+## Runtime Environment
+
+For networked games, you can configure the runtime environment to distinguish between server and client logic.
+
+### Global Configuration (Recommended)
+
+Set the runtime environment once at the Core level - all Scenes will inherit this setting:
+
+```typescript
+import { Core } from '@esengine/ecs-framework';
+
+// Method 1: Set in Core.create()
+Core.create({ runtimeEnvironment: 'server' });
+
+// Method 2: Set static property directly
+Core.runtimeEnvironment = 'server';
+```
+
+### Per-Scene Override
+
+Individual scenes can override the global setting:
+
+```typescript
+const clientScene = new Scene({ runtimeEnvironment: 'client' });
+```
+
+### Environment Types
+
+| Environment | Use Case |
+|-------------|----------|
+| `'standalone'` | Single-player games (default) |
+| `'server'` | Game server, authoritative logic |
+| `'client'` | Game client, rendering/input |
+
+### Checking Environment in Systems
+
+```typescript
+class CollectibleSpawnSystem extends EntitySystem {
+  private checkCollections(): void {
+    // Skip on client - only server handles authoritative logic
+    if (!this.scene.isServer) return;
+
+    // Server-authoritative spawn logic...
+  }
+}
+```
+
+See [System Runtime Decorators](/en/guide/system/index#runtime-environment-decorators) for decorator-based approach.

 ```
 
+## Runtime Environment Decorators
+
+For networked games, you can use decorators to control which environment a system method runs in.
+
+### Available Decorators
+
+| Decorator | Effect |
+|-----------|--------|
+| `@ServerOnly()` | Method only executes on server |
+| `@ClientOnly()` | Method only executes on client |
+| `@NotServer()` | Method skipped on server |
+| `@NotClient()` | Method skipped on client |
+
+### Usage Example
+
+```typescript
+import { EntitySystem, ServerOnly, ClientOnly } from '@esengine/ecs-framework';
+
+class GameSystem extends EntitySystem {
+  @ServerOnly()
+  private spawnEnemies(): void {
+    // Only runs on server - authoritative spawn logic
+  }
+
+  @ClientOnly()
+  private playEffects(): void {
+    // Only runs on client - visual effects
+  }
+}
+```
+
+### Simple Conditional Check
+
+For simple cases, a direct check is often clearer than decorators:
+
+```typescript
+class CollectibleSystem extends EntitySystem {
+  private checkCollections(): void {
+    if (!this.scene.isServer) return;  // Skip on client
+
+    // Server-authoritative logic...
+  }
+}

+## Using Custom Executors in BehaviorTreeBuilder
+
+After defining a custom executor with `@NodeExecutorMetadata`, use the `.action()` method in the builder:
+
+```typescript
+import { BehaviorTreeBuilder, BehaviorTreeStarter } from '@esengine/behavior-tree';
+
+// Use custom executor in behavior tree
+const tree = BehaviorTreeBuilder.create('CombatAI')
+    .defineBlackboardVariable('health', 100)
+    .defineBlackboardVariable('target', null)
+    .selector('Root')
+        .sequence('AttackSequence')
+            // Use custom action - matches implementationType in decorator
+            .action('AttackAction', 'Attack', { damage: 25 })
+            .action('MoveToTarget', 'Chase')
+        .end()
+        .action('WaitAction', 'Idle', { duration: 1000 })
+    .end()
+    .build();
+
+// Start the behavior tree
+const entity = scene.createEntity('Enemy');
+BehaviorTreeStarter.start(entity, tree);
+```
+
+### Builder Methods for Custom Nodes
+
+| Method | Description |
+|--------|-------------|
+| `.action(type, name?, config?)` | Add custom action node |
+| `.condition(type, name?, config?)` | Add custom condition node |
+| `.executeAction(name)` | Use blackboard function `action_{name}` |
+| `.executeCondition(name)` | Use blackboard function `condition_{name}` |
+
+### Complete Example
+
+```typescript
+// 1. Define custom executor
+@NodeExecutorMetadata({
+    implementationType: 'AttackAction',
+    nodeType: NodeType.Action,
+    displayName: 'Attack',
+    category: 'Combat',
+    configSchema: {
+        damage: { type: 'number', default: 10, supportBinding: true }
+    }
+})
+class AttackAction implements INodeExecutor {
+    execute(context: NodeExecutionContext): TaskStatus {
+        const damage = BindingHelper.getValue<number>(context, 'damage', 10);
+        console.log(`Attacking with ${damage} damage!`);
+        return TaskStatus.Success;
+    }
+}
+
+// 2. Build and use
+const tree = BehaviorTreeBuilder.create('AI')
+    .selector('Root')
+        .action('AttackAction', 'Attack', { damage: 50 })

+title: "Authentication"
+description: "Add authentication to your game server with JWT and Session providers"
+---
+
+The `@esengine/server` package includes a pluggable authentication system that supports JWT, session-based auth, and custom providers.
+
+## Installation
+
+Authentication is included in the server package:
+
+```bash
+npm install @esengine/server jsonwebtoken
+```
+
+> Note: `jsonwebtoken` is an optional peer dependency, required only for JWT authentication.
+
+## Quick Start
+
+### JWT Authentication
+
+```typescript
+import { createServer } from '@esengine/server'
+import { withAuth, createJwtAuthProvider, withRoomAuth, requireAuth } from '@esengine/server/auth'
+
+// Create JWT provider
+const jwtProvider = createJwtAuthProvider({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600, // 1 hour
+})
+
+// Wrap server with authentication
+const server = withAuth(await createServer({ port: 3000 }), {
+    provider: jwtProvider,
+    extractCredentials: (req) => {
+        const url = new URL(req.url ?? '', 'http://localhost')
+        return url.searchParams.get('token')
+    },
+})
+
+// Define authenticated room
+class GameRoom extends withRoomAuth(Room, { requireAuth: true }) {
+    onJoin(player) {
+        console.log(`${player.user?.name} joined!`)
+    }
+}
+
+server.define('game', GameRoom)
+await server.start()
+```
+
+## Auth Providers
+
+### JWT Provider
+
+Use JSON Web Tokens for stateless authentication:
+
+```typescript
+import { createJwtAuthProvider } from '@esengine/server/auth'
+
+const jwtProvider = createJwtAuthProvider({
+    // Required: secret key
+    secret: 'your-secret-key',
+
+    // Optional: algorithm (default: HS256)
+    algorithm: 'HS256',
+
+    // Optional: expiration in seconds (default: 3600)
+    expiresIn: 3600,
+
+    // Optional: issuer for validation
+    issuer: 'my-game-server',
+
+    // Optional: audience for validation
+    audience: 'my-game-client',
+
+    // Optional: custom user extraction
+    getUser: async (payload) => {
+        // Fetch user from database
+        return await db.users.findById(payload.sub)
+    },
+})
+
+// Sign a token (for login endpoints)
+const token = jwtProvider.sign({
+    sub: user.id,
+    name: user.name,
+    roles: ['player'],
+})
+
+// Decode without verification (for debugging)
+const payload = jwtProvider.decode(token)
+```
+
+### Custom Provider
+
+You can create custom authentication providers by implementing the `IAuthProvider` interface to integrate with any authentication system (OAuth, LDAP, custom database auth, etc.).
+
+#### IAuthProvider Interface
+
+```typescript
+interface IAuthProvider<TUser = unknown, TCredentials = unknown> {
+    /** Provider name */
+    readonly name: string;
+
+    /** Verify credentials */
+    verify(credentials: TCredentials): Promise<AuthResult<TUser>>;
+
+    /** Refresh token (optional) */
+    refresh?(token: string): Promise<AuthResult<TUser>>;
+
+    /** Revoke token (optional) */
+    revoke?(token: string): Promise<boolean>;
+}
+
+interface AuthResult<TUser> {
+    success: boolean;
+    user?: TUser;
+    error?: string;
+    errorCode?: AuthErrorCode;
+    token?: string;
+    expiresAt?: number;
+}
+
+type AuthErrorCode =
+    | 'INVALID_CREDENTIALS'
+    | 'EXPIRED_TOKEN'
+    | 'INVALID_TOKEN'
+    | 'USER_NOT_FOUND'
+    | 'ACCOUNT_DISABLED'
+    | 'RATE_LIMITED'
+    | 'INSUFFICIENT_PERMISSIONS';
+```
+
+#### Custom Provider Examples
+
+**Example 1: Database Password Authentication**
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface User {
+    id: string
+    username: string
+    roles: string[]
+}
+
+interface PasswordCredentials {
+    username: string
+    password: string
+}
+
+class DatabaseAuthProvider implements IAuthProvider<User, PasswordCredentials> {
+    readonly name = 'database'
+
+    async verify(credentials: PasswordCredentials): Promise<AuthResult<User>> {
+        const { username, password } = credentials
+
+        // Query user from database
+        const user = await db.users.findByUsername(username)
+        if (!user) {
+            return {
+                success: false,
+                error: 'User not found',
+                errorCode: 'USER_NOT_FOUND'
+            }
+        }
+
+        // Verify password (using bcrypt or similar)
+        const isValid = await bcrypt.compare(password, user.passwordHash)
+        if (!isValid) {
+            return {
+                success: false,
+                error: 'Invalid password',
+                errorCode: 'INVALID_CREDENTIALS'
+            }
+        }
+
+        // Check account status
+        if (user.disabled) {
+            return {
+                success: false,
+                error: 'Account is disabled',
+                errorCode: 'ACCOUNT_DISABLED'
+            }
+        }
+
+        return {
+            success: true,
+            user: {
+                id: user.id,
+                username: user.username,
+                roles: user.roles
+            }
+        }
+    }
+}
+```
+
+**Example 2: OAuth/Third-party Authentication**
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface OAuthUser {
+    id: string
+    email: string
+    name: string
+    provider: string
+    roles: string[]
+}
+
+interface OAuthCredentials {
+    provider: 'google' | 'github' | 'discord'
+    accessToken: string
+}
+
+class OAuthProvider implements IAuthProvider<OAuthUser, OAuthCredentials> {
+    readonly name = 'oauth'
+
+    async verify(credentials: OAuthCredentials): Promise<AuthResult<OAuthUser>> {
+        const { provider, accessToken } = credentials
+
+        try {
+            // Verify token with provider
+            const profile = await this.fetchUserProfile(provider, accessToken)
+
+            // Find or create local user
+            let user = await db.users.findByOAuth(provider, profile.id)
+            if (!user) {
+                user = await db.users.create({
+                    oauthProvider: provider,
+                    oauthId: profile.id,
+                    email: profile.email,
+                    name: profile.name,
+                    roles: ['player']
+                })
+            }
+
+            return {
+                success: true,
+                user: {
+                    id: user.id,
+                    email: user.email,
+                    name: user.name,
+                    provider,
+                    roles: user.roles
+                }
+            }
+        } catch (error) {
+            return {
+                success: false,
+                error: 'OAuth verification failed',
+                errorCode: 'INVALID_TOKEN'
+            }
+        }
+    }
+
+    private async fetchUserProfile(provider: string, token: string) {
+        switch (provider) {
+            case 'google':
+                return fetch('https://www.googleapis.com/oauth2/v2/userinfo', {
+                    headers: { Authorization: `Bearer ${token}` }
+                }).then(r => r.json())
+            case 'github':
+                return fetch('https://api.github.com/user', {
+                    headers: { Authorization: `Bearer ${token}` }
+                }).then(r => r.json())
+            // Other providers...
+            default:
+                throw new Error(`Unsupported provider: ${provider}`)
+        }
+    }
+}
+```
+
+**Example 3: API Key Authentication**
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface ApiUser {
+    id: string
+    name: string
+    roles: string[]
+    rateLimit: number
+}
+
+class ApiKeyAuthProvider implements IAuthProvider<ApiUser, string> {
+    readonly name = 'api-key'
+
+    private revokedKeys = new Set<string>()
+
+    async verify(apiKey: string): Promise<AuthResult<ApiUser>> {
+        if (!apiKey || !apiKey.startsWith('sk_')) {
+            return {
+                success: false,
+                error: 'Invalid API Key format',
+                errorCode: 'INVALID_TOKEN'
+            }
+        }
+
+        if (this.revokedKeys.has(apiKey)) {
+            return {
+                success: false,
+                error: 'API Key has been revoked',
+                errorCode: 'INVALID_TOKEN'
+            }
+        }
+
+        // Query API Key from database
+        const keyData = await db.apiKeys.findByKey(apiKey)
+        if (!keyData) {
+            return {
+                success: false,
+                error: 'API Key not found',
+                errorCode: 'INVALID_CREDENTIALS'
+            }
+        }
+
+        // Check expiration
+        if (keyData.expiresAt && keyData.expiresAt < Date.now()) {
+            return {
+                success: false,
+                error: 'API Key has expired',
+                errorCode: 'EXPIRED_TOKEN'
+            }
+        }
+
+        return {
+            success: true,
+            user: {
+                id: keyData.userId,
+                name: keyData.name,
+                roles: keyData.roles,
+                rateLimit: keyData.rateLimit
+            },
+            expiresAt: keyData.expiresAt
+        }
+    }
+
+    async revoke(apiKey: string): Promise<boolean> {
+        this.revokedKeys.add(apiKey)
+        await db.apiKeys.revoke(apiKey)
+        return true
+    }
+}
+```
+
+#### Using Custom Providers
+
+```typescript
+import { createServer } from '@esengine/server'
+import { withAuth } from '@esengine/server/auth'
+
+// Create custom provider
+const dbAuthProvider = new DatabaseAuthProvider()
+
+// Or use OAuth provider
+const oauthProvider = new OAuthProvider()
+
+// Use custom provider
+const server = withAuth(await createServer({ port: 3000 }), {
+    provider: dbAuthProvider, // or oauthProvider
+
+    // Extract credentials from WebSocket connection request
+    extractCredentials: (req) => {
+        const url = new URL(req.url, 'http://localhost')
+
+        // For database auth: get from query params
+        const username = url.searchParams.get('username')
+        const password = url.searchParams.get('password')
+        if (username && password) {
+            return { username, password }
+        }
+
+        // For OAuth: get from token param
+        const provider = url.searchParams.get('provider')
+        const accessToken = url.searchParams.get('access_token')
+        if (provider && accessToken) {
+            return { provider, accessToken }
+        }
+
+        // For API Key: get from header
+        const apiKey = req.headers['x-api-key']
+        if (apiKey) {
+            return apiKey as string
+        }
+
+        return null
+    },
+
+    onAuthFailure: (conn, error) => {
+        console.log(`Auth failed: ${error.errorCode} - ${error.error}`)
+    }
+})
+
+await server.start()
+```
+
+#### Combining Multiple Providers
+
+You can create a composite provider to support multiple authentication methods:
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface MultiAuthCredentials {
+    type: 'jwt' | 'oauth' | 'apikey' | 'password'
+    data: unknown
+}
+
+class MultiAuthProvider implements IAuthProvider<User, MultiAuthCredentials> {
+    readonly name = 'multi'
+
+    constructor(
+        private jwtProvider: JwtAuthProvider<User>,
+        private oauthProvider: OAuthProvider,
+        private apiKeyProvider: ApiKeyAuthProvider,
+        private dbProvider: DatabaseAuthProvider
+    ) {}
+
+    async verify(credentials: MultiAuthCredentials): Promise<AuthResult<User>> {
+        switch (credentials.type) {
+            case 'jwt':
+                return this.jwtProvider.verify(credentials.data as string)
+            case 'oauth':
+                return this.oauthProvider.verify(credentials.data as OAuthCredentials)
+            case 'apikey':
+                return this.apiKeyProvider.verify(credentials.data as string)
+            case 'password':
+                return this.dbProvider.verify(credentials.data as PasswordCredentials)
+            default:
+                return {
+                    success: false,
+                    error: 'Unsupported authentication type',
+                    errorCode: 'INVALID_CREDENTIALS'
+                }
+        }
+    }
+}
+```
+
+### Session Provider
+
+Use server-side sessions for stateful authentication:
+
+```typescript
+import { createSessionAuthProvider, type ISessionStorage } from '@esengine/server/auth'
+
+// Custom storage implementation
+const storage: ISessionStorage = {
+    async get<T>(key: string): Promise<T | null> {
+        return await redis.get(key)
+    },
+    async set<T>(key: string, value: T): Promise<void> {
+        await redis.set(key, value)
+    },
+    async delete(key: string): Promise<boolean> {
+        return await redis.del(key) > 0
+    },
+}
+
+const sessionProvider = createSessionAuthProvider({
+    storage,
+    sessionTTL: 86400000, // 24 hours in ms
+
+    // Optional: validate user on each request
+    validateUser: (user) => !user.banned,
+})
+
+// Create session (for login endpoints)
+const sessionId = await sessionProvider.createSession(user, {
+    ipAddress: req.ip,
+    userAgent: req.headers['user-agent'],
+})
+
+// Revoke session (for logout)
+await sessionProvider.revoke(sessionId)
+```
+
+## Server Auth Mixin
+
+The `withAuth` function wraps your server to add authentication:
+
+```typescript
+import { withAuth } from '@esengine/server/auth'
+
+const server = withAuth(baseServer, {
+    // Required: auth provider
+    provider: jwtProvider,
+
+    // Required: extract credentials from request
+    extractCredentials: (req) => {
+        // From query string
+        return new URL(req.url, 'http://localhost').searchParams.get('token')
+
+        // Or from headers
+        // return req.headers['authorization']?.replace('Bearer ', '')
+    },
+
+    // Optional: handle auth failure
+    onAuthFailed: (conn, error) => {
+        console.log(`Auth failed: ${error}`)
+    },
+})
+```
+
+### Accessing Auth Context
+
+After authentication, the auth context is available on connections:
+
+```typescript
+import { getAuthContext } from '@esengine/server/auth'
+
+server.onConnect = (conn) => {
+    const auth = getAuthContext(conn)
+
+    if (auth.isAuthenticated) {
+        console.log(`User ${auth.userId} connected`)
+        console.log(`Roles: ${auth.roles}`)
+    }
+}
+```
+
+## Room Auth Mixin
+
+The `withRoomAuth` function adds authentication checks to rooms:
+
+```typescript
+import { withRoomAuth, type AuthPlayer } from '@esengine/server/auth'
+
+interface User {
+    id: string
+    name: string
+    roles: string[]
+}
+
+class GameRoom extends withRoomAuth<User>(Room, {
+    // Require authentication to join
+    requireAuth: true,
+
+    // Optional: require specific roles
+    allowedRoles: ['player', 'premium'],
+
+    // Optional: role check mode ('any' or 'all')
+    roleCheckMode: 'any',
+}) {
+    // player has .auth and .user properties
+    onJoin(player: AuthPlayer<User>) {
+        console.log(`${player.user?.name} joined`)
+        console.log(`Is premium: ${player.auth.hasRole('premium')}`)
+    }
+
+    // Optional: custom auth validation
+    async onAuth(player: AuthPlayer<User>): Promise<boolean> {
+        // Additional validation logic
+        if (player.auth.hasRole('banned')) {
+            return false
+        }
+        return true
+    }
+
+    @onMessage('Chat')
+    handleChat(data: { text: string }, player: AuthPlayer<User>) {
+        this.broadcast('Chat', {
+            from: player.user?.name ?? 'Guest',
+            text: data.text,
+        })
+    }
+}
+```
+
+### AuthPlayer Interface
+
+Players in auth rooms have additional properties:
+
+```typescript
+interface AuthPlayer<TUser> extends Player {
+    // Full auth context
+    readonly auth: IAuthContext<TUser>
+
+    // User info (shortcut for auth.user)
+    readonly user: TUser | null
+}
+```
+
+### Room Auth Helpers
+
+```typescript
+class GameRoom extends withRoomAuth<User>(Room) {
+    someMethod() {
+        // Get player by user ID
+        const player = this.getPlayerByUserId('user-123')
+
+        // Get all players with a role
+        const admins = this.getPlayersByRole('admin')
+
+        // Get player with auth info
+        const authPlayer = this.getAuthPlayer(playerId)
+    }
+}
+```
+
+## Auth Decorators
+
+### @requireAuth
+
+Mark message handlers as requiring authentication:
+
+```typescript
+import { requireAuth, requireRole, onMessage } from '@esengine/server/auth'
+
+class GameRoom extends withRoomAuth(Room) {
+    @requireAuth()
+    @onMessage('Trade')
+    handleTrade(data: TradeData, player: AuthPlayer) {
+        // Only authenticated players can trade
+    }
+
+    @requireAuth({ allowGuest: true })
+    @onMessage('Chat')
+    handleChat(data: ChatData, player: AuthPlayer) {
+        // Guests can also chat
+    }
+}
+```
+
+### @requireRole
+
+Require specific roles for message handlers:
+
+```typescript
+class AdminRoom extends withRoomAuth(Room) {
+    @requireRole('admin')
+    @onMessage('Ban')
+    handleBan(data: BanData, player: AuthPlayer) {
+        // Only admins can ban
+    }
+
+    @requireRole(['moderator', 'admin'])
+    @onMessage('Mute')
+    handleMute(data: MuteData, player: AuthPlayer) {
+        // Moderators OR admins can mute
+    }
+
+    @requireRole(['verified', 'premium'], { mode: 'all' })
+    @onMessage('SpecialFeature')
+    handleSpecial(data: any, player: AuthPlayer) {
+        // Requires BOTH verified AND premium roles
+    }
+}
+```
+
+## Auth Context API
+
+The auth context provides various methods for checking authentication state:
+
+```typescript
+interface IAuthContext<TUser> {
+    // Authentication state
+    readonly isAuthenticated: boolean
+    readonly user: TUser | null
+    readonly userId: string | null
+    readonly roles: ReadonlyArray<string>
+    readonly authenticatedAt: number | null
+    readonly expiresAt: number | null
+
+    // Role checking
+    hasRole(role: string): boolean
+    hasAnyRole(roles: string[]): boolean
+    hasAllRoles(roles: string[]): boolean
+}
+```
+
+The `AuthContext` class (implementation) also provides:
+
+```typescript
+class AuthContext<TUser> implements IAuthContext<TUser> {
+    // Set authentication from result
+    setAuthenticated(result: AuthResult<TUser>): void
+
+    // Clear authentication state
+    clear(): void
+}
+```
+
+## Testing
+
+Use the mock auth provider for unit tests:
+
+```typescript
+import { createMockAuthProvider } from '@esengine/server/auth/testing'
+
+// Create mock provider with preset users
+const mockProvider = createMockAuthProvider({
+    users: [
+        { id: '1', name: 'Alice', roles: ['player'] },
+        { id: '2', name: 'Bob', roles: ['admin', 'player'] },
+    ],
+    autoCreate: true, // Create users for unknown tokens
+})
+
+// Use in tests
+const server = withAuth(testServer, {
+    provider: mockProvider,
+    extractCredentials: (req) => req.headers['x-token'],
+})
+
+// Verify with user ID as token
+const result = await mockProvider.verify('1')
+// result.user = { id: '1', name: 'Alice', roles: ['player'] }
+
+// Add/remove users dynamically
+mockProvider.addUser({ id: '3', name: 'Charlie', roles: ['guest'] })
+mockProvider.removeUser('3')
+
+// Revoke tokens
+await mockProvider.revoke('1')
+
+// Reset to initial state
+mockProvider.clear()
+```
+
+## Error Handling
+
+Auth errors include error codes for programmatic handling:
+
+```typescript
+type AuthErrorCode =
+    | 'INVALID_CREDENTIALS'       // Invalid username/password
+    | 'INVALID_TOKEN'             // Token is malformed or invalid
+    | 'EXPIRED_TOKEN'             // Token has expired
+    | 'USER_NOT_FOUND'            // User lookup failed
+    | 'ACCOUNT_DISABLED'          // User account is disabled
+    | 'RATE_LIMITED'              // Too many requests
+    | 'INSUFFICIENT_PERMISSIONS'  // Insufficient permissions
+
+// In your auth failure handler
+const server = withAuth(baseServer, {
+    provider: jwtProvider,
+    extractCredentials,
+    onAuthFailed: (conn, error) => {
+        switch (error.errorCode) {
+            case 'EXPIRED_TOKEN':
+                conn.send('AuthError', { code: 'TOKEN_EXPIRED' })
+                break
+            case 'INVALID_TOKEN':
+                conn.send('AuthError', { code: 'INVALID_TOKEN' })
+                break
+            default:
+                conn.close()
+        }
+    },
+})
+```
+
+## Complete Example
+
+Here's a complete example with JWT authentication:
+
+```typescript
+// server.ts
+import { createServer } from '@esengine/server'
+import {
+    withAuth,
+    withRoomAuth,
+    createJwtAuthProvider,
+    requireAuth,
+    requireRole,
+    type AuthPlayer,
+} from '@esengine/server/auth'
+
+// Types
+interface User {
+    id: string
+    name: string
+    roles: string[]
+}
+
+// JWT Provider
+const jwtProvider = createJwtAuthProvider<User>({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600,
+    getUser: async (payload) => ({
+        id: payload.sub as string,
+        name: payload.name as string,
+        roles: (payload.roles as string[]) ?? [],
+    }),
+})
+
+// Create authenticated server
+const server = withAuth(
+    await createServer({ port: 3000 }),
+    {
+        provider: jwtProvider,
+        extractCredentials: (req) => {
+            return new URL(req.url ?? '', 'http://localhost')
+                .searchParams.get('token')
+        },
+    }
+)
+
+// Game Room with auth
+class GameRoom extends withRoomAuth<User>(Room, {
+    requireAuth: true,
+    allowedRoles: ['player'],
+}) {
+    onCreate() {
+        console.log('Game room created')
+    }
+
+    onJoin(player: AuthPlayer<User>) {
+        console.log(`${player.user?.name} joined!`)
+        this.broadcast('PlayerJoined', {
+            id: player.id,
+            name: player.user?.name,
+        })
+    }
+
+    @requireAuth()
+    @onMessage('Move')
+    handleMove(data: { x: number; y: number }, player: AuthPlayer<User>) {
+        // Handle movement
+    }
+
+    @requireRole('admin')
+    @onMessage('Kick')
+    handleKick(data: { playerId: string }, player: AuthPlayer<User>) {
+        const target = this.getPlayer(data.playerId)
+        if (target) {
+            this.kick(target, 'Kicked by admin')
+        }
+    }
+}
+
+server.define('game', GameRoom)
+await server.start()
+```
+
+## Best Practices
+
+1. **Secure your secrets**: Never hardcode JWT secrets. Use environment variables.
+
+2. **Set reasonable expiration**: Balance security and user experience when setting token TTL.
+
+3. **Validate on critical actions**: Use `@requireAuth` on sensitive message handlers.
+
+4. **Use role-based access**: Implement proper role hierarchy for admin functions.
+
+5. **Handle token refresh**: Implement token refresh logic for long sessions.
+
+6. **Log auth events**: Track login attempts and failures for security monitoring.
+
+7. **Test auth flows**: Use `MockAuthProvider` to test authentication scenarios.

+title: "Rate Limiting"
+description: "Protect your game server from abuse with configurable rate limiting"
+---
+
+The `@esengine/server` package includes a pluggable rate limiting system to protect against DDoS attacks, message flooding, and other abuse.
+
+## Installation
+
+Rate limiting is included in the server package:
+
+```bash
+npm install @esengine/server
+```
+
+## Quick Start
+
+```typescript
+import { Room, onMessage } from '@esengine/server'
+import { withRateLimit, rateLimit, noRateLimit } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room, {
+    messagesPerSecond: 10,
+    burstSize: 20,
+    onLimited: (player, type, result) => {
+        player.send('Error', {
+            code: 'RATE_LIMITED',
+            retryAfter: result.retryAfter,
+        })
+    },
+}) {
+    @onMessage('Move')
+    handleMove(data: { x: number; y: number }, player: Player) {
+        // Protected by rate limit (10 msg/s default)
+    }
+
+    @rateLimit({ messagesPerSecond: 1 })
+    @onMessage('Trade')
+    handleTrade(data: TradeData, player: Player) {
+        // Stricter limit for trading
+    }
+
+    @noRateLimit()
+    @onMessage('Heartbeat')
+    handleHeartbeat(data: any, player: Player) {
+        // No rate limit for heartbeat
+    }
+}
+```
+
+## Rate Limit Strategies
+
+### Token Bucket (Default)
+
+The token bucket algorithm allows burst traffic while maintaining long-term rate limits. Tokens are added at a fixed rate, and each request consumes tokens.
+
+```typescript
+import { withRateLimit } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room, {
+    strategy: 'token-bucket',
+    messagesPerSecond: 10, // Refill rate
+    burstSize: 20,         // Bucket capacity
+}) { }
+```
+
+**How it works:**
+```
+Config: rate=10/s, burstSize=20
+
+[0s]   Bucket full: 20 tokens
+[0s]   15 messages → allowed, 5 remaining
+[0.5s] Refill 5 tokens → 10 tokens
+[0.5s] 8 messages → allowed, 2 remaining
+[0.6s] Refill 1 token → 3 tokens
+[0.6s] 5 messages → 3 allowed, 2 rejected
+```
+
+**Best for:** Most general use cases, balances burst tolerance with protection.
+
+### Sliding Window
+
+The sliding window algorithm precisely tracks requests within a time window. More accurate than fixed window but uses slightly more memory.
+
+```typescript
+class GameRoom extends withRateLimit(Room, {
+    strategy: 'sliding-window',
+    messagesPerSecond: 10,
+    burstSize: 10,
+}) { }
+```
+
+**Best for:** When you need precise rate limiting without burst tolerance.
+
+### Fixed Window
+
+The fixed window algorithm divides time into fixed intervals and counts requests per interval. Simple and memory-efficient but allows 2x burst at window boundaries.
+
+```typescript
+class GameRoom extends withRateLimit(Room, {
+    strategy: 'fixed-window',
+    messagesPerSecond: 10,
+    burstSize: 10,
+}) { }
+```
+
+**Best for:** Simple scenarios where boundary burst is acceptable.
+
+## Configuration
+
+### Room Configuration
+
+```typescript
+import { withRateLimit } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room, {
+    // Messages allowed per second (default: 10)
+    messagesPerSecond: 10,
+
+    // Burst capacity / bucket size (default: 20)
+    burstSize: 20,
+
+    // Strategy: 'token-bucket' | 'sliding-window' | 'fixed-window'
+    strategy: 'token-bucket',
+
+    // Callback when rate limited
+    onLimited: (player, messageType, result) => {
+        player.send('RateLimited', {
+            type: messageType,
+            retryAfter: result.retryAfter,
+        })
+    },
+
+    // Disconnect on rate limit (default: false)
+    disconnectOnLimit: false,
+
+    // Disconnect after N consecutive limits (0 = never)
+    maxConsecutiveLimits: 10,
+
+    // Custom key function (default: player.id)
+    getKey: (player) => player.id,
+
+    // Cleanup interval in ms (default: 60000)
+    cleanupInterval: 60000,
+}) { }
+```
+
+### Per-Message Configuration
+
+Use decorators to configure rate limits for specific messages:
+
+```typescript
+import { rateLimit, noRateLimit, rateLimitMessage } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room) {
+    // Custom rate limit for this message
+    @rateLimit({ messagesPerSecond: 1, burstSize: 2 })
+    @onMessage('Trade')
+    handleTrade(data: TradeData, player: Player) { }
+
+    // This message costs 5 tokens
+    @rateLimit({ cost: 5 })
+    @onMessage('ExpensiveAction')
+    handleExpensive(data: any, player: Player) { }
+
+    // Exempt from rate limiting
+    @noRateLimit()
+    @onMessage('Heartbeat')
+    handleHeartbeat(data: any, player: Player) { }
+
+    // Alternative: specify message type explicitly
+    @rateLimitMessage('SpecialAction', { messagesPerSecond: 2 })
+    @onMessage('SpecialAction')
+    handleSpecial(data: any, player: Player) { }
+}
+```
+
+## Combining with Authentication
+
+Rate limiting works seamlessly with the authentication system:
+
+```typescript
+import { withRoomAuth } from '@esengine/server/auth'
+import { withRateLimit } from '@esengine/server/ratelimit'
+
+// Apply both mixins
+class GameRoom extends withRateLimit(
+    withRoomAuth(Room, { requireAuth: true }),
+    { messagesPerSecond: 10 }
+) {
+    onJoin(player: AuthPlayer) {
+        console.log(`${player.user?.name} joined with rate limit protection`)
+    }
+}
+```
+
+## Rate Limit Result
+
+When a message is rate limited, the callback receives a result object:
+
+```typescript
+interface RateLimitResult {
+    // Whether the request was allowed
+    allowed: boolean
+
+    // Remaining quota
+    remaining: number
+
+    // When the quota resets (timestamp)
+    resetAt: number
+
+    // How long to wait before retrying (ms)
+    retryAfter?: number
+}
+```
+
+## Accessing Rate Limit Context
+
+You can access the rate limit context for any player:
+
+```typescript
+import { getPlayerRateLimitContext } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room) {
+    someMethod(player: Player) {
+        const context = this.getRateLimitContext(player)
+
+        // Check without consuming
+        const status = context?.check()
+        console.log(`Remaining: ${status?.remaining}`)
+
+        // Get consecutive limit count
+        console.log(`Consecutive limits: ${context?.consecutiveLimitCount}`)
+    }
+}
+
+// Or use the standalone function
+const context = getPlayerRateLimitContext(player)
+```
+
+## Custom Strategies
+
+You can use the strategies directly for custom implementations:
+
+```typescript
+import {
+    TokenBucketStrategy,
+    SlidingWindowStrategy,
+    FixedWindowStrategy,
+    createTokenBucketStrategy,
+} from '@esengine/server/ratelimit'
+
+// Create strategy directly
+const strategy = createTokenBucketStrategy({
+    rate: 10,      // tokens per second
+    capacity: 20,  // max tokens
+})
+
+// Check and consume
+const result = strategy.consume('player-123')
+if (result.allowed) {
+    // Process message
+} else {
+    // Rate limited, wait result.retryAfter ms
+}
+
+// Check without consuming
+const status = strategy.getStatus('player-123')
+
+// Reset a key
+strategy.reset('player-123')
+
+// Cleanup expired records
+strategy.cleanup()
+```
+
+## Rate Limit Context
+
+The `RateLimitContext` class manages rate limiting for a single player:
+
+```typescript
+import { RateLimitContext, TokenBucketStrategy } from '@esengine/server/ratelimit'
+
+const strategy = new TokenBucketStrategy({ rate: 10, capacity: 20 })
+const context = new RateLimitContext('player-123', strategy)
+
+// Check without consuming
+context.check()
+
+// Consume quota
+context.consume()
+
+// Consume with cost
+context.consume(undefined, 5)
+
+// Consume for specific message type
+context.consume('Trade')
+
+// Set per-message strategy
+context.setMessageStrategy('Trade', new TokenBucketStrategy({ rate: 1, capacity: 2 }))
+
+// Reset
+context.reset()
+
+// Get consecutive limit count
+console.log(context.consecutiveLimitCount)
+```
+
+## Room Lifecycle Hook
+
+You can override the `onRateLimited` hook for custom handling:
+
+```typescript
+class GameRoom extends withRateLimit(Room) {
+    onRateLimited(player: Player, messageType: string, result: RateLimitResult) {
+        // Log the event
+        console.log(`Player ${player.id} rate limited on ${messageType}`)
+
+        // Send custom error
+        player.send('SystemMessage', {
+            type: 'warning',
+            message: `Slow down! Try again in ${result.retryAfter}ms`,
+        })
+    }
+}
+```
+
+## Best Practices
+
+1. **Start with token bucket**: It's the most flexible algorithm for games.
+
+2. **Set appropriate limits**: Consider your game's mechanics:
+   - Movement messages: Higher limits (20-60/s)
+   - Chat messages: Lower limits (1-5/s)
+   - Trade/purchase: Very low limits (0.5-1/s)
+
+3. **Use burst capacity**: Allow short bursts for responsive gameplay:
+   ```typescript
+   messagesPerSecond: 10,
+   burstSize: 30, // Allow 3s worth of burst
+   ```
+
+4. **Exempt critical messages**: Don't rate limit heartbeats or system messages:
+   ```typescript
+   @noRateLimit()
+   @onMessage('Heartbeat')
+   handleHeartbeat() { }
+   ```
+
+5. **Combine with auth**: Rate limit by user ID for authenticated users:
+   ```typescript
+   getKey: (player) => player.auth?.userId ?? player.id
+   ```
+
+6. **Monitor and adjust**: Log rate limit events to tune your limits:
+   ```typescript
+   onLimited: (player, type, result) => {
+       metrics.increment('rate_limit', { messageType: type })
+   }
+   ```
+
+7. **Graceful degradation**: Send informative errors instead of just disconnecting:
+   ```typescript
+   onLimited: (player, type, result) => {
+       player.send('Error', {
+           code: 'RATE_LIMITED',
+           message: 'Too many requests',
+           retryAfter: result.retryAfter,
+       })
+   }
+   ```
+
+## Complete Example
+
+```typescript
+import { Room, onMessage, type Player } from '@esengine/server'
+import { withRoomAuth, type AuthPlayer } from '@esengine/server/auth'
+import {
+    withRateLimit,
+    rateLimit,
+    noRateLimit,
+    type RateLimitResult,
+} from '@esengine/server/ratelimit'
+
+interface User {
+    id: string
+    name: string
+    premium: boolean
+}
+
+// Combine auth and rate limit
+class GameRoom extends withRateLimit(
+    withRoomAuth<User>(Room, { requireAuth: true }),
+    {
+        messagesPerSecond: 10,
+        burstSize: 30,
+        strategy: 'token-bucket',
+
+        // Use user ID for rate limiting
+        getKey: (player) => (player as AuthPlayer<User>).user?.id ?? player.id,
+
+        // Handle rate limits
+        onLimited: (player, type, result) => {
+            player.send('Error', {
+                code: 'RATE_LIMITED',
+                messageType: type,
+                retryAfter: result.retryAfter,
+            })
+        },
+
+        // Disconnect after 20 consecutive rate limits
+        maxConsecutiveLimits: 20,
+    }
+) {
+    onCreate() {
+        console.log('Room created with auth + rate limit protection')
+    }
+
+    onJoin(player: AuthPlayer<User>) {
+        this.broadcast('PlayerJoined', { name: player.user?.name })
+    }
+

+## HTTP Routing
+
+Supports HTTP API sharing the same port with WebSocket, ideal for login, registration, and similar scenarios.
+
+### File-based Routing
+
+Create route files in the `httpDir` directory, automatically mapped to HTTP endpoints:
+
+```
+src/http/
+├── login.ts       → POST /api/login
+├── register.ts    → POST /api/register
+├── health.ts      → GET  /api/health (set method: 'GET')
+└── users/
+    └── [id].ts    → POST /api/users/:id (dynamic route)
+```
+
+### Define Routes
+
+Use `defineHttp` to define type-safe route handlers:
+
+```typescript
+// src/http/login.ts
+import { defineHttp } from '@esengine/server'
+
+interface LoginBody {
+    username: string
+    password: string
+}
+
+export default defineHttp<LoginBody>({
+    method: 'POST',  // Default POST, options: GET/PUT/DELETE/PATCH
+    handler(req, res) {
+        const { username, password } = req.body
+
+        // Validate credentials...
+        if (!isValid(username, password)) {
+            res.error(401, 'Invalid credentials')
+            return
+        }
+
+        // Generate token...
+        res.json({ token: '...', userId: '...' })
+    }
+})
+```
+
+### Request Object (HttpRequest)
+
+```typescript
+interface HttpRequest {
+    raw: IncomingMessage     // Node.js raw request
+    method: string           // Request method
+    path: string             // Request path
+    query: Record<string, string>  // Query parameters
+    headers: Record<string, string | string[] | undefined>
+    body: unknown            // Parsed JSON body
+    ip: string               // Client IP
+}
+```
+
+### Response Object (HttpResponse)
+
+```typescript
+interface HttpResponse {
+    raw: ServerResponse      // Node.js raw response
+    status(code: number): HttpResponse   // Set status code (chainable)
+    header(name: string, value: string): HttpResponse  // Set header (chainable)
+    json(data: unknown): void            // Send JSON
+    text(data: string): void             // Send text
+    error(code: number, message: string): void  // Send error
+}
+```
+
+### Usage Example
+
+```typescript
+// Complete login server example
+import { createServer, defineHttp } from '@esengine/server'
+import { createJwtAuthProvider, withAuth } from '@esengine/server/auth'
+
+const jwtProvider = createJwtAuthProvider({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600 * 24,
+})
+
+const server = await createServer({
+    port: 8080,
+    httpDir: 'src/http',
+    httpPrefix: '/api',
+    cors: true,
+})
+
+// Wrap with auth (WebSocket connections validate token)
+const authServer = withAuth(server, {
+    provider: jwtProvider,
+    extractCredentials: (req) => {
+        const url = new URL(req.url, 'http://localhost')
+        return url.searchParams.get('token')
+    },
+})
+
+await authServer.start()
+// HTTP: http://localhost:8080/api/*
+// WebSocket: ws://localhost:8080?token=xxx
+```
+
+### Inline Routes
+
+Routes can also be defined directly in configuration (merged with file routes, inline takes priority):
+
+```typescript
+const server = await createServer({
+    port: 8080,
+    http: {
+        '/health': {
+            GET: (req, res) => res.json({ status: 'ok' }),
+        },
+        '/webhook': async (req, res) => {
+            // Accepts all methods
+            await handleWebhook(req.body)
+            res.json({ received: true })
+        },
+    },
+})
+```

+## ECSRoom
+
+`ECSRoom` is a room base class with ECS World support, suitable for games that need ECS architecture.
+
+### Server Startup
+
+```typescript
+import { Core } from '@esengine/ecs-framework';
+import { createServer } from '@esengine/server';
+import { GameRoom } from './rooms/GameRoom.js';
+
+// Initialize Core

+## @NetworkEntity Decorator
+
+The `@NetworkEntity` decorator marks components for automatic spawn/despawn broadcasting. When an entity containing this component is created or destroyed, ECSRoom automatically broadcasts the corresponding message to all clients.
+
+### Basic Usage
+
+```typescript
+import { Component, ECSComponent, sync, NetworkEntity } from '@esengine/ecs-framework';
+
+@ECSComponent('Enemy')
+@NetworkEntity('Enemy')
+class EnemyComponent extends Component {
+    @sync('float32') x: number = 0;
+    @sync('float32') y: number = 0;
+    @sync('uint16') health: number = 100;
+}
+```
+
+When adding this component to an entity, ECSRoom automatically broadcasts the spawn message:
+
+```typescript
+// Server-side
+const entity = scene.createEntity('Enemy');
+entity.addComponent(new EnemyComponent()); // Auto-broadcasts spawn
+
+// Destroying auto-broadcasts despawn
+entity.destroy(); // Auto-broadcasts despawn
+```
+
+### Configuration Options
+
+```typescript
+@NetworkEntity('Bullet', {
+    autoSpawn: true,    // Auto-broadcast spawn (default true)
+    autoDespawn: false  // Disable auto-broadcast despawn
+})
+class BulletComponent extends Component { }
+```
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `autoSpawn` | `boolean` | `true` | Auto-broadcast spawn when component is added |
+| `autoDespawn` | `boolean` | `true` | Auto-broadcast despawn when entity is destroyed |
+
+### Initialization Order
+
+When using `@NetworkEntity`, initialize data **before** adding the component:
+
+```typescript
+// ✅ Correct: Initialize first, then add
+const comp = new PlayerComponent();
+comp.playerId = player.id;
+comp.x = 100;
+comp.y = 200;
+entity.addComponent(comp); // Data is correct at spawn
+
+// ❌ Wrong: Add first, then initialize
+const comp = entity.addComponent(new PlayerComponent());
+comp.playerId = player.id; // Data has default values at spawn
+```
+
+### Simplified GameRoom
+
+With `@NetworkEntity`, GameRoom becomes much cleaner:
+
+```typescript
+// No manual callbacks needed
+class GameRoom extends ECSRoom {
+    private setupSystems(): void {
+        // Enemy spawn system (auto-broadcasts spawn)
+        this.addSystem(new EnemySpawnSystem());
+
+        // Enemy AI system
+        const enemyAI = new EnemyAISystem();
+        enemyAI.onDeath((enemy) => {
+            enemy.destroy(); // Auto-broadcasts despawn
+        });
+        this.addSystem(enemyAI);
+    }
+}
+```
+
+### ECSRoom Configuration
+
+You can disable the auto network entity feature in ECSRoom:
+
+```typescript
+class GameRoom extends ECSRoom {
+    constructor() {
+        super({
+            enableAutoNetworkEntity: false // Disable auto-broadcasting
+        });
+    }
+}
+```
+
+## Component Sync System
+
+ECS component state synchronization based on `@sync` decorator.
+
+### Define Sync Component
+
+```typescript
+import { Component, ECSComponent, sync } from '@esengine/ecs-framework';
+
+@ECSComponent('Player')
+class PlayerComponent extends Component {
+    @sync("string") name: string = "";
+    @sync("uint16") score: number = 0;
+    @sync("float32") x: number = 0;
+    @sync("float32") y: number = 0;
+
+    // Fields without @sync won't be synced
+    localData: any;
+}
+```
+
+### Server-side Encoding
+
+```typescript
+import { ComponentSyncSystem } from '@esengine/network';
+
+const syncSystem = new ComponentSyncSystem({}, true);
+scene.addSystem(syncSystem);
+
+// Encode all entities (initial connection)
+const fullData = syncSystem.encodeAllEntities(true);
+sendToClient(fullData);
+
+// Encode delta (only send changes)
+const deltaData = syncSystem.encodeDelta();
+if (deltaData) {
+    broadcast(deltaData);
+}
+```
+
+### Client-side Decoding
+
+```typescript
+const syncSystem = new ComponentSyncSystem();
+scene.addSystem(syncSystem);
+
+// Register component types
+syncSystem.registerComponent(PlayerComponent);
+
+// Listen for sync events
+syncSystem.addSyncListener((event) => {
+    if (event.type === 'entitySpawned') {
+        console.log('New entity:', event.entityId);
+    }
+});
+
+// Apply state
+syncSystem.applySnapshot(data);
+```
+
+### Sync Types
+
+| Type | Description | Bytes |
+|------|-------------|-------|
+| `"boolean"` | Boolean | 1 |
+| `"int8"` / `"uint8"` | 8-bit integer | 1 |
+| `"int16"` / `"uint16"` | 16-bit integer | 2 |
+| `"int32"` / `"uint32"` | 32-bit integer | 4 |
+| `"float32"` | 32-bit float | 4 |
+| `"float64"` | 64-bit float | 8 |
+| `"string"` | String | Variable |
+

+
+## Transaction State
+
+A transaction can be in the following states:
+
+```typescript
+type TransactionState =
+    | 'pending'     // Waiting to execute
+    | 'executing'   // Executing
+    | 'committed'   // Committed
+    | 'rolledback'  // Rolled back
+    | 'failed'      // Failed
+```
+
+## TransactionContext
+
+The transaction context encapsulates transaction state, operations, and execution logic.
+
+### Creating Transactions
+
+```typescript
+import { TransactionManager } from '@esengine/transaction';
+
+const manager = new TransactionManager();
+
+// Method 1: Manual management with begin()
+const tx = manager.begin({ timeout: 5000 });
+tx.addOperation(op1);
+tx.addOperation(op2);
+const result = await tx.execute();
+
+// Method 2: Automatic management with run()
+const result = await manager.run((tx) => {
+    tx.addOperation(op1);
+    tx.addOperation(op2);
+});
+```
+
+### Chaining Operations
+
+```typescript
+const result = await manager.run((tx) => {
+    tx.addOperation(new CurrencyOperation({ ... }))
+      .addOperation(new InventoryOperation({ ... }))
+      .addOperation(new InventoryOperation({ ... }));
+});
+```
+
+### Context Data
+
+Operations can share data through the context:
+
+```typescript
+class CustomOperation extends BaseOperation<MyData, MyResult> {
+    async execute(ctx: ITransactionContext): Promise<OperationResult<MyResult>> {
+        // Read data set by previous operations
+        const previousResult = ctx.get<number>('previousValue');
+
+        // Set data for subsequent operations
+        ctx.set('myResult', { value: 123 });
+
+        return this.success({ ... });
+    }
+}
+```
+
+## TransactionManager
+
+The transaction manager is responsible for creating, executing, and recovering transactions.
+
+### Configuration Options
+
+```typescript
+interface TransactionManagerConfig {
+    storage?: ITransactionStorage;    // Storage instance
+    defaultTimeout?: number;          // Default timeout (ms)
+    serverId?: string;                // Server ID (for distributed)
+    autoRecover?: boolean;            // Auto-recover pending transactions
+}
+
+const manager = new TransactionManager({
+    storage: new RedisStorage({ client: redis }),
+    defaultTimeout: 10000,
+    serverId: 'server-1',
+    autoRecover: true,
+});
+```
+
+### Distributed Locking
+
+```typescript
+// Acquire lock
+const token = await manager.acquireLock('player:123:inventory', 10000);
+
+if (token) {
+    try {
+        // Perform operations
+        await doSomething();
+    } finally {
+        // Release lock
+        await manager.releaseLock('player:123:inventory', token);
+    }
+}
+
+// Or use withLock for convenience
+await manager.withLock('player:123:inventory', async () => {
+    await doSomething();
+}, 10000);
+```
+
+### Transaction Recovery
+
+Recover pending transactions after server restart:
+
+```typescript
+const manager = new TransactionManager({
+    storage: new RedisStorage({ client: redis }),
+    serverId: 'server-1',
+});
+
+// Recover pending transactions
+const recoveredCount = await manager.recover();
+console.log(`Recovered ${recoveredCount} transactions`);
+```
+
+## Saga Pattern
+
+The transaction system uses the Saga pattern. Each operation must implement `execute` and `compensate` methods:
+
+```typescript
+interface ITransactionOperation<TData, TResult> {
+    readonly name: string;
+    readonly data: TData;
+
+    // Validate preconditions
+    validate(ctx: ITransactionContext): Promise<boolean>;
+
+    // Forward execution
+    execute(ctx: ITransactionContext): Promise<OperationResult<TResult>>;
+
+    // Compensate (rollback)
+    compensate(ctx: ITransactionContext): Promise<void>;
+}
+```
+
+### Execution Flow
+
+```
+Begin Transaction

+    ▼

+
+## Cross-Server Transaction Examples
+
+### Scenario: Cross-Server Purchase
+
+A player purchases an item on a game server, with currency on an account server and items on an inventory server.
+
+```typescript
+const orchestrator = new SagaOrchestrator({
+    storage: redisStorage,
+    serverId: 'purchase-orchestrator',
+});
+
+async function crossServerPurchase(
+    playerId: string,
+    itemId: string,
+    price: number
+): Promise<SagaResult> {
+    return orchestrator.execute([
+        // Step 1: Deduct balance on account server
+        {
+            name: 'deduct_balance',
+            serverId: 'account-server',
+            data: { playerId, amount: price },
+            execute: async (data) => {
+                const result = await accountService.deduct(data.playerId, data.amount);
+                return { success: result.ok, error: result.error };
+            },
+            compensate: async (data) => {
+                await accountService.refund(data.playerId, data.amount);
+            },
+        },
+
+        // Step 2: Add item on inventory server
+        {
+            name: 'add_item',
+            serverId: 'inventory-server',
+            data: { playerId, itemId },
+            execute: async (data) => {
+                const result = await inventoryService.addItem(data.playerId, data.itemId);
+                return { success: result.ok, error: result.error };
+            },
+            compensate: async (data) => {
+                await inventoryService.removeItem(data.playerId, data.itemId);
+            },
+        },
+
+        // Step 3: Record purchase log
+        {
+            name: 'log_purchase',
+            serverId: 'log-server',
+            data: { playerId, itemId, price, timestamp: Date.now() },
+            execute: async (data) => {
+                await logService.recordPurchase(data);
+                return { success: true };
+            },
+            compensate: async (data) => {
+                await logService.cancelPurchase(data);
+            },
+        },
+    ]);
+}
+```
+
+### Scenario: Cross-Server Trade
+
+Two players on different servers trade with each other.
+
+```typescript
+async function crossServerTrade(
+    playerA: { id: string; server: string; items: string[] },
+    playerB: { id: string; server: string; items: string[] }
+): Promise<SagaResult> {
+    const steps: SagaStep[] = [];
+
+    // Remove items from player A
+    for (const itemId of playerA.items) {
+        steps.push({
+            name: `remove_${playerA.id}_${itemId}`,
+            serverId: playerA.server,
+            data: { playerId: playerA.id, itemId },
+            execute: async (data) => {
+                return await inventoryService.removeItem(data.playerId, data.itemId);
+            },
+            compensate: async (data) => {
+                await inventoryService.addItem(data.playerId, data.itemId);
+            },
+        });
+    }
+
+    // Add items to player B (from A)
+    for (const itemId of playerA.items) {
+        steps.push({
+            name: `add_${playerB.id}_${itemId}`,
+            serverId: playerB.server,
+            data: { playerId: playerB.id, itemId },
+            execute: async (data) => {
+                return await inventoryService.addItem(data.playerId, data.itemId);
+            },
+            compensate: async (data) => {
+                await inventoryService.removeItem(data.playerId, data.itemId);
+            },
+        });
+    }
+
+    // Similarly handle player B's items...
+
+    return orchestrator.execute(steps);
+}
+```
+
+## Recovering Incomplete Sagas
+
+Recover incomplete Sagas after server restart:
+
+```typescript
+const orchestrator = new SagaOrchestrator({
+    storage: redisStorage,
+    serverId: 'my-orchestrator',
+});
+
+// Recover incomplete Sagas (will execute compensation)
+const recoveredCount = await orchestrator.recover();
+console.log(`Recovered ${recoveredCount} sagas`);
+```
+
+## Best Practices
+
+### 1. Idempotency
+
+Ensure all operations are idempotent:
+
+```typescript
+{
+    execute: async (data) => {
+        // Use unique ID to ensure idempotency
+        const result = await service.process(data.requestId, data);
+        return { success: result.ok };
+    },
+    compensate: async (data) => {
+        // Compensation must also be idempotent
+        await service.rollback(data.requestId);
+    },
+}
+```
+
+### 2. Timeout Handling
+
+Set appropriate timeout values:
+
+```typescript
+const orchestrator = new SagaOrchestrator({
+    timeout: 60000,  // Cross-server operations need longer timeout
+});
+```
+
+### 3. Monitoring and Alerts
+
+Log Saga execution results:
+
+```typescript
+const result = await orchestrator.execute(steps);
+
+if (!result.success) {
+    // Send alert
+    alertService.send({
+        type: 'saga_failed',
+        sagaId: result.sagaId,
+        failedStep: result.failedStep,
+        error: result.error,
+    });
+
+    // Log details
+    const log = await orchestrator.getSagaLog(result.sagaId);
+    logger.error('Saga failed', { log });
+}
+```

+title: "Transaction System"
+description: "Game transaction system with distributed support for shop purchases, player trading, and more"
+---
+
+`@esengine/transaction` provides comprehensive game transaction capabilities based on the Saga pattern, supporting shop purchases, player trading, multi-step tasks, and distributed transactions with Redis/MongoDB.
+
+## Overview
+
+The transaction system solves common data consistency problems in games:
+
+| Scenario | Problem | Solution |
+|----------|---------|----------|
+| Shop Purchase | Payment succeeded but item not delivered | Atomic transaction with auto-rollback |
+| Player Trade | One party transferred items but other didn't receive | Saga compensation mechanism |
+| Cross-Server | Data inconsistency across servers | Distributed lock + transaction log |
+
+## Installation
+
+```bash
+npm install @esengine/transaction
+```
+
+Optional dependencies (install based on storage needs):
+```bash
+npm install ioredis   # Redis storage
+npm install mongodb   # MongoDB storage
+```
+

+
+## Quick Start
+
+### Basic Usage
+
+```typescript
+import {
+    TransactionManager,
+    MemoryStorage,
+    CurrencyOperation,
+    InventoryOperation,
+} from '@esengine/transaction';
+
+// Create transaction manager
+const manager = new TransactionManager({
+    storage: new MemoryStorage(),
+    defaultTimeout: 10000,
+});
+
+// Execute transaction
+const result = await manager.run((tx) => {
+    // Deduct gold
+    tx.addOperation(new CurrencyOperation({
+        type: 'deduct',
+        playerId: 'player1',
+        currency: 'gold',
+        amount: 100,
+    }));
+
+    // Add item
+    tx.addOperation(new InventoryOperation({
+        type: 'add',
+        playerId: 'player1',
+        itemId: 'sword_001',
+        quantity: 1,
+    }));
+});
+
+if (result.success) {
+    console.log('Purchase successful!');
+} else {
+    console.log('Purchase failed:', result.error);
+}
+```
+
+### Player Trading
+
+```typescript
+import { TradeOperation } from '@esengine/transaction';
+
+const result = await manager.run((tx) => {
+    tx.addOperation(new TradeOperation({
+        tradeId: 'trade_001',
+        partyA: {
+            playerId: 'player1',
+            items: [{ itemId: 'sword', quantity: 1 }],
+        },
+        partyB: {
+            playerId: 'player2',
+            currencies: [{ currency: 'gold', amount: 1000 }],
+        },
+    }));
+}, { timeout: 30000 });
+```
+
+### Using Redis Storage
+
+```typescript
+import Redis from 'ioredis';
+import { TransactionManager, RedisStorage } from '@esengine/transaction';
+
+const redis = new Redis('redis://localhost:6379');
+const storage = new RedisStorage({ client: redis });
+
+const manager = new TransactionManager({ storage });
+```
+
+### Using MongoDB Storage
+
+```typescript
+import { MongoClient } from 'mongodb';
+import { TransactionManager, MongoStorage } from '@esengine/transaction';
+
+const client = new MongoClient('mongodb://localhost:27017');
+await client.connect();
+const db = client.db('game');
+
+const storage = new MongoStorage({ db });
+await storage.ensureIndexes();
+
+const manager = new TransactionManager({ storage });
+```
+
+## Room Integration
+
+```typescript
+import { Room } from '@esengine/server';
+import { withTransactions, CurrencyOperation, RedisStorage } from '@esengine/transaction';
+
+class GameRoom extends withTransactions(Room, {
+    storage: new RedisStorage({ client: redisClient }),
+}) {
+    @onMessage('Buy')
+    async handleBuy(data: { itemId: string }, player: Player) {
+        const result = await this.runTransaction((tx) => {
+            tx.addOperation(new CurrencyOperation({
+                type: 'deduct',
+                playerId: player.id,
+                currency: 'gold',
+                amount: getItemPrice(data.itemId),
+            }));
+        });
+
+        if (result.success) {
+            player.send('buy_success', { itemId: data.itemId });
+        } else {
+            player.send('buy_failed', { error: result.error });
+        }
+    }
+}
+```

+## Service Tokens
+
+For dependency injection:
+
+```typescript
+import {
+    TransactionManagerToken,
+    TransactionStorageToken,
+} from '@esengine/transaction';
+
+const manager = services.get(TransactionManagerToken);
+```
+
+## Best Practices
+
+### 1. Operation Granularity
+
+```typescript
+// ✅ Good: Fine-grained operations, easy to rollback
+tx.addOperation(new CurrencyOperation({ type: 'deduct', ... }));
+tx.addOperation(new InventoryOperation({ type: 'add', ... }));
+
+// ❌ Bad: Coarse-grained operation, hard to partially rollback
+tx.addOperation(new ComplexPurchaseOperation({ ... }));
+```
+
+### 2. Timeout Settings
+
+```typescript
+// Simple operations: short timeout
+await manager.run(tx => { ... }, { timeout: 5000 });
+
+// Complex trades: longer timeout
+await manager.run(tx => { ... }, { timeout: 30000 });
+
+// Cross-server: even longer timeout
+await manager.run(tx => { ... }, { timeout: 60000, distributed: true });
+```
+
+### 3. Error Handling
+
+```typescript
+const result = await manager.run((tx) => { ... });
+
+if (!result.success) {
+    // Log the error
+    logger.error('Transaction failed', {
+        transactionId: result.transactionId,
+        error: result.error,
+        duration: result.duration,
+    });
+
+    // Notify user
+    player.send('error', { message: getErrorMessage(result.error) });
+}
+```

+## BaseOperation
+
+Base class for all operations, providing a common implementation template.
+
+```typescript

+    }
+}
+```
+
+## TradeOperation
+
+Handles item and currency exchange between players.
+
+### Basic Usage
+
+```typescript
+import { TradeOperation } from '@esengine/transaction';
+
+tx.addOperation(new TradeOperation({
+    tradeId: 'trade_001',
+    partyA: {
+        playerId: 'player1',
+        items: [{ itemId: 'sword', quantity: 1 }],
+        currencies: [{ currency: 'diamond', amount: 10 }],
+    },
+    partyB: {
+        playerId: 'player2',
+        currencies: [{ currency: 'gold', amount: 1000 }],
+    },
+    reason: 'player_trade',
+}));
+```
+
+### Operation Data
+
+```typescript
+interface TradeOperationData {
+    tradeId: string;      // Trade ID
+    partyA: TradeParty;   // Trade initiator
+    partyB: TradeParty;   // Trade receiver
+    reason?: string;      // Reason/note
+}
+
+interface TradeParty {
+    playerId: string;              // Player ID
+    items?: TradeItem[];           // Items to give
+    currencies?: TradeCurrency[];  // Currencies to give
+}
+
+interface TradeItem {
+    itemId: string;
+    quantity: number;
+}
+
+interface TradeCurrency {
+    currency: string;
+    amount: number;
+}
+```
+
+### Execution Flow
+
+TradeOperation internally generates the following sub-operation sequence:
+
+```
+1. Remove partyA's items
+2. Add items to partyB (from partyA)
+3. Deduct partyA's currencies
+4. Add currencies to partyB (from partyA)
+5. Remove partyB's items
+6. Add items to partyA (from partyB)
+7. Deduct partyB's currencies
+8. Add currencies to partyA (from partyB)
+```
+
+If any step fails, all previous operations are rolled back.
+
+### Using Custom Providers
+
+```typescript
+const op = new TradeOperation({ ... });
+op.setProvider({
+    currencyProvider: new MyCurrencyProvider(),
+    inventoryProvider: new MyInventoryProvider(),
+});
+tx.addOperation(op);
+```
+
+## Factory Functions
+
+Each operation class provides a factory function:
+
+```typescript
+import {
+    createCurrencyOperation,
+    createInventoryOperation,
+    createTradeOperation,
+} from '@esengine/transaction';
+
+tx.addOperation(createCurrencyOperation({
+    type: 'deduct',
+    playerId: 'player1',
+    currency: 'gold',
+    amount: 100,
+}));
+
+tx.addOperation(createInventoryOperation({
+    type: 'add',
+    playerId: 'player1',
+    itemId: 'sword',
+    quantity: 1,
+}));
+```

+title: "Storage Layer"
+description: "Transaction storage interface and implementations: MemoryStorage, RedisStorage, MongoStorage"
+---
+
+## Storage Interface
+
+All storage implementations must implement the `ITransactionStorage` interface:
+
+```typescript
+interface ITransactionStorage {
+    // Lifecycle
+    close?(): Promise<void>;
+
+    // Distributed lock
+    acquireLock(key: string, ttl: number): Promise<string | null>;
+    releaseLock(key: string, token: string): Promise<boolean>;
+
+    // Transaction log
+    saveTransaction(tx: TransactionLog): Promise<void>;
+    getTransaction(id: string): Promise<TransactionLog | null>;
+    updateTransactionState(id: string, state: TransactionState): Promise<void>;
+    updateOperationState(txId: string, opIndex: number, state: string, error?: string): Promise<void>;
+    getPendingTransactions(serverId?: string): Promise<TransactionLog[]>;
+    deleteTransaction(id: string): Promise<void>;
+
+    // Data operations
+    get<T>(key: string): Promise<T | null>;
+    set<T>(key: string, value: T, ttl?: number): Promise<void>;
+    delete(key: string): Promise<boolean>;
+}
+```
+
+## MemoryStorage
+
+In-memory storage, suitable for development and testing.
+
+```typescript
+import { MemoryStorage } from '@esengine/transaction';
+
+const storage = new MemoryStorage({
+    maxTransactions: 1000,  // Maximum transaction log count
+});
+
+const manager = new TransactionManager({ storage });
+```
+
+### Characteristics
+
+- ✅ No external dependencies
+- ✅ Fast, good for debugging
+- ❌ Data only stored in memory
+- ❌ No true distributed locking
+- ❌ Data lost on restart
+
+### Test Helpers
+
+```typescript
+// Clear all data
+storage.clear();
+
+// Get transaction count
+console.log(storage.transactionCount);
+```
+
+## RedisStorage
+
+Redis storage, suitable for production distributed systems. Uses factory pattern with lazy connection.
+
+```typescript
+import Redis from 'ioredis';
+import { RedisStorage } from '@esengine/transaction';
+
+// Factory pattern: lazy connection, connects on first operation
+const storage = new RedisStorage({
+    factory: () => new Redis('redis://localhost:6379'),
+    prefix: 'tx:',              // Key prefix
+    transactionTTL: 86400,      // Transaction log TTL (seconds)
+});
+
+const manager = new TransactionManager({ storage });
+
+// Close connection when done
+await storage.close();
+
+// Or use await using for automatic cleanup (TypeScript 5.2+)
+await using storage = new RedisStorage({
+    factory: () => new Redis('redis://localhost:6379')
+});
+// Automatically closed when scope ends
+```
+
+### Characteristics
+
+- ✅ High-performance distributed locking
+- ✅ Fast read/write
+- ✅ Supports TTL auto-expiration
+- ✅ Suitable for high concurrency
+- ❌ Requires Redis server
+
+### Distributed Lock Implementation
+
+Uses Redis `SET NX EX` for distributed locking:
+
+```typescript
+// Acquire lock (atomic operation)
+SET tx:lock:player:123 <token> NX EX 10
+
+// Release lock (Lua script for atomicity)
+if redis.call("get", KEYS[1]) == ARGV[1] then
+    return redis.call("del", KEYS[1])
+else
+    return 0
+end
+```
+
+### Key Structure
+
+```
+tx:lock:{key}           - Distributed locks
+tx:tx:{id}              - Transaction logs
+tx:server:{id}:txs      - Server transaction index
+tx:data:{key}           - Business data
+```
+
+## MongoStorage
+
+MongoDB storage, suitable for scenarios requiring persistence and complex queries. Uses shared connection from `@esengine/database-drivers`.
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers';
+import { createMongoStorage, TransactionManager } from '@esengine/transaction';
+
+// Create shared connection
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game'
+});
+await mongo.connect();
+
+// Create storage using shared connection
+const storage = createMongoStorage(mongo, {
+    transactionCollection: 'transactions',  // Transaction log collection (optional)
+    dataCollection: 'transaction_data',     // Business data collection (optional)
+    lockCollection: 'transaction_locks',    // Lock collection (optional)
+});
+
+// Create indexes (run on first startup)
+await storage.ensureIndexes();
+
+const manager = new TransactionManager({ storage });
+
+// Close storage (does not close shared connection)
+await storage.close();
+
+// Shared connection can continue to be used by other modules
+const userRepo = new UserRepository(mongo);  // @esengine/database
+
+// Finally close the shared connection
+await mongo.disconnect();
+```
+
+### Characteristics
+
+- ✅ Persistent storage
+- ✅ Supports complex queries
+- ✅ Transaction logs are traceable
+- ✅ Suitable for audit requirements
+- ❌ Slightly lower performance than Redis
+- ❌ Requires MongoDB server
+
+### Index Structure
+
+```javascript
+// transactions collection
+{ state: 1 }
+{ 'metadata.serverId': 1 }
+{ createdAt: 1 }
+
+// transaction_locks collection
+{ expireAt: 1 }  // TTL index
+
+// transaction_data collection
+{ expireAt: 1 }  // TTL index
+```
+
+### Distributed Lock Implementation
+
+Uses MongoDB unique index for distributed locking:
+
+```typescript
+// Acquire lock
+db.transaction_locks.insertOne({
+    _id: 'player:123',
+    token: '<token>',
+    expireAt: new Date(Date.now() + 10000)
+});
+
+// If key exists, check if expired
+db.transaction_locks.updateOne(
+    { _id: 'player:123', expireAt: { $lt: new Date() } },
+    { $set: { token: '<token>', expireAt: new Date(Date.now() + 10000) } }
+);
+```
+
+## Storage Selection Guide
+
+| Scenario | Recommended Storage | Reason |
+|----------|---------------------|--------|
+| Development/Testing | MemoryStorage | No dependencies, fast startup |
+| Single-machine Production | RedisStorage | High performance, simple |
+| Distributed System | RedisStorage | True distributed locking |
+| Audit Required | MongoStorage | Persistent logs |
+| Mixed Requirements | Redis + Mongo | Redis for locks, Mongo for logs |
+
+## Custom Storage
+
+Implement `ITransactionStorage` interface to create custom storage:
+
+```typescript
+import { ITransactionStorage, TransactionLog, TransactionState } from '@esengine/transaction';
+
+class MyCustomStorage implements ITransactionStorage {
+    async acquireLock(key: string, ttl: number): Promise<string | null> {
+        // Implement distributed lock acquisition
+    }
+
+    async releaseLock(key: string, token: string): Promise<boolean> {
+        // Implement distributed lock release
+    }
+
+    async saveTransaction(tx: TransactionLog): Promise<void> {
+        // Save transaction log
+    }
+
+    // ... implement other methods
+}
+```

+
+对于网络游戏，你可以配置运行时环境来区分服务端和客户端逻辑。
+
+### 全局配置（推荐）
+
+在 Core 层级设置一次运行时环境，所有场景都会继承此设置：
+
+```typescript
+import { Core } from '@esengine/ecs-framework';
+
+// 方式1：在 Core.create() 中设置
+Core.create({ runtimeEnvironment: 'server' });
+
+// 方式2：直接设置静态属性
+Core.runtimeEnvironment = 'server';
+```
+
+### 单个场景覆盖
+
+个别场景可以覆盖全局设置：
+
+```typescript
+const clientScene = new Scene({ runtimeEnvironment: 'client' });
+```
+
+### 环境类型
+
+| 环境 | 使用场景 |
+|------|----------|
+| `'standalone'` | 单机游戏（默认） |
+| `'server'` | 游戏服务器，权威逻辑 |
+| `'client'` | 游戏客户端，渲染/输入 |
+
+### 在系统中检查环境
+
+```typescript
+class CollectibleSpawnSystem extends EntitySystem {
+  private checkCollections(): void {
+    // 客户端跳过 - 只有服务端处理权威逻辑
+    if (!this.scene.isServer) return;

+
+### 可用装饰器
+
+| 装饰器 | 效果 |
+|--------|------|
+| `@ServerOnly()` | 方法仅在服务端执行 |
+| `@ClientOnly()` | 方法仅在客户端执行 |
+| `@NotServer()` | 方法在服务端跳过 |
+| `@NotClient()` | 方法在客户端跳过 |
+
+### 使用示例
+
+```typescript
+import { EntitySystem, ServerOnly, ClientOnly } from '@esengine/ecs-framework';
+
+class GameSystem extends EntitySystem {
+  @ServerOnly()
+  private spawnEnemies(): void {

+  @ClientOnly()
+  private playEffects(): void {
+    // 仅在客户端运行 - 视觉效果
+  }
+}
+```
+
+### 简单条件检查
+
+对于简单场景，直接检查通常比装饰器更清晰：

+### MongoDB 连接
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers'
+
+// 创建连接
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game',
+    pool: {
+        minSize: 5,
+        maxSize: 20
+    },
+    autoReconnect: true
+})
+
+// 监听事件
+mongo.on('connected', () => console.log('MongoDB 已连接'))
+mongo.on('disconnected', () => console.log('MongoDB 已断开'))
+mongo.on('error', (e) => console.error('错误:', e.error))
+
+// 建立连接
+await mongo.connect()
+
+// 使用集合
+const users = mongo.collection<User>('users')
+await users.insertOne({ name: 'John', score: 100 })
+
+const user = await users.findOne({ name: 'John' })
+
+// 完成后断开连接
+await mongo.disconnect()
+```
+
+### Redis 连接
+
+```typescript
+import { createRedisConnection } from '@esengine/database-drivers'
+
+const redis = createRedisConnection({
+    host: 'localhost',
+    port: 6379,
+    keyPrefix: 'game:',

+})
+
+await redis.connect()
+
+// 基本操作
+await redis.set('session:123', 'data', 3600)  // 带 TTL
+const value = await redis.get('session:123')
+
+await redis.disconnect()
+```
+
+## 服务容器集成
+

+import { ServiceContainer } from '@esengine/ecs-framework'
+import {
+    createMongoConnection,
+    MongoConnectionToken,
+    RedisConnectionToken
+} from '@esengine/database-drivers'
+
+const services = new ServiceContainer()
+
+// 注册连接
+const mongo = createMongoConnection({ uri: '...', database: 'game' })
+await mongo.connect()
+services.register(MongoConnectionToken, mongo)
+
+// 在其他模块中获取
+const connection = services.get(MongoConnectionToken)
+const users = connection.collection('users')

+
+// 查询
+const user = await users.findOne({ name: 'John' })
+
+const topUsers = await users.find(

+    { id: '1' },
+    { $inc: { score: 10 } }
+)
+
+// 删除
+await users.deleteOne({ id: '1' })
+```
+
+### 批量操作
+
+```typescript
+// 批量插入
+await users.insertMany([
+    { id: '1', name: 'Alice', email: 'alice@example.com', score: 100 },
+    { id: '2', name: 'Bob', email: 'bob@example.com', score: 200 },

+    { $set: { status: 'inactive' } }
+)
+
+// 批量删除
+await users.deleteMany({ status: 'inactive' })
+```
+
+### 索引管理
+
+```typescript
+// 创建索引
+await users.createIndex({ email: 1 }, { unique: true })
+await users.createIndex({ score: -1 })
+await users.createIndex({ name: 1, score: -1 })
+```

+
+// 使用 Pipeline

+pipeline.set('key1', 'value1')
+pipeline.set('key2', 'value2')

+
+// 使用事务
+const multi = client.multi()
+multi.incr('counter')
+multi.get('counter')
+const results = await multi.exec()
+
+// 使用 Lua 脚本
+const result = await client.eval(
+    `return redis.call('get', KEYS[1])`,
+    1,
+    'mykey'
+)
+```
+
+## 与事务系统集成

+
+const redis = createRedisConnection({
+    host: 'localhost',

+    factory: () => redis.getNativeClient(),
+    prefix: 'tx:'
+})
+
+const txManager = new TransactionManager({ storage })

+
+### $like 语法
+
+- `%` - 匹配任意字符序列
+- `_` - 匹配单个字符

+{ name: { $like: '%oh%' } }
+
+// 第二个字符是 'o'
+{ name: { $like: '_o%' } }
+```
+
+### $regex 语法
+
+使用标准正则表达式：
+
+```typescript
+// 以 'John' 开头（大小写不敏感）
+{ name: { $regex: '^john' } }
+
+// Gmail 邮箱
+{ email: { $regex: '@gmail\\.com$' } }
+
+// 包含数字
+{ username: { $regex: '\\d+' } }
+```
+
+## 排序
+
+```typescript
+await repo.findMany({
+    sort: {
+        score: 'desc',  // 降序
+        name: 'asc'     // 升序
+    }
+})
+```
+
+## 分页
+
+### 使用 limit/offset
+
+```typescript
+// 第一页

+title: "用户管理"
+description: "UserRepository 用户注册、认证、角色管理"
+---
+
+## 概述
+
+`UserRepository` 提供开箱即用的用户管理功能：
+
+- 用户注册与认证
+- 密码哈希（使用 scrypt）
+- 角色管理
+- 账户状态管理
+
+## 快速开始
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers'
+import { UserRepository } from '@esengine/database'
+
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game'
+})
+await mongo.connect()
+
+const userRepo = new UserRepository(mongo)
+```
+
+## 用户注册
+
+```typescript
+const user = await userRepo.register({
+    username: 'john',
+    password: 'securePassword123',
+    email: 'john@example.com',      // 可选
+    displayName: 'John Doe',         // 可选
+    roles: ['player']                // 可选，默认 []
+})
+
+console.log(user)
+// {
+//   id: 'uuid-...',
+//   username: 'john',
+//   email: 'john@example.com',
+//   displayName: 'John Doe',
+//   roles: ['player'],
+//   status: 'active',
+//   createdAt: Date,
+//   updatedAt: Date
+// }
+```
+
+**注意**：`register` 返回的 `SafeUser` 不包含密码哈希。
+
+## 用户认证
+
+```typescript
+const user = await userRepo.authenticate('john', 'securePassword123')
+
+if (user) {
+    console.log('登录成功:', user.username)
+} else {
+    console.log('用户名或密码错误')
+}
+```
+
+## 密码管理
+
+### 修改密码
+
+```typescript
+const success = await userRepo.changePassword(
+    userId,
+    'oldPassword123',
+    'newPassword456'
+)
+
+if (success) {
+    console.log('密码修改成功')
+} else {
+    console.log('原密码错误')
+}
+```
+
+### 重置密码
+
+```typescript
+// 管理员直接重置密码
+const success = await userRepo.resetPassword(userId, 'newPassword123')
+```
+
+## 角色管理
+
+### 添加角色
+
+```typescript
+await userRepo.addRole(userId, 'admin')
+await userRepo.addRole(userId, 'moderator')
+```
+
+### 移除角色
+
+```typescript
+await userRepo.removeRole(userId, 'moderator')
+```
+
+### 查询角色
+
+```typescript
+// 查找所有管理员
+const admins = await userRepo.findByRole('admin')
+
+// 检查用户是否有某角色
+const user = await userRepo.findById(userId)
+const isAdmin = user?.roles.includes('admin')
+```
+
+## 查询用户
+
+### 按用户名查找
+
+```typescript
+const user = await userRepo.findByUsername('john')
+```
+
+### 按邮箱查找
+
+```typescript
+const user = await userRepo.findByEmail('john@example.com')
+```
+
+### 按角色查找
+
+```typescript
+const admins = await userRepo.findByRole('admin')
+```
+
+### 使用继承的方法
+
+```typescript
+// 分页查询
+const result = await userRepo.findPaginated(
+    { page: 1, pageSize: 20 },
+    {
+        where: { status: 'active' },
+        sort: { createdAt: 'desc' }
+    }
+)
+
+// 复杂查询
+const users = await userRepo.findMany({
+    where: {
+        status: 'active',
+        roles: { $in: ['admin', 'moderator'] }
+    }
+})
+```
+
+## 账户状态
+
+```typescript
+type UserStatus = 'active' | 'inactive' | 'banned' | 'suspended'
+```
+
+### 更新状态
+
+```typescript
+await userRepo.update(userId, { status: 'banned' })
+```
+
+### 查询特定状态
+
+```typescript
+const activeUsers = await userRepo.findMany({
+    where: { status: 'active' }
+})
+
+const bannedUsers = await userRepo.findMany({
+    where: { status: 'banned' }
+})
+```
+
+## 类型定义
+
+### UserEntity
+
+```typescript
+interface UserEntity extends BaseEntity {
+    username: string
+    passwordHash: string
+    email?: string
+    displayName?: string
+    roles: string[]
+    status: UserStatus
+    lastLoginAt?: Date
+}
+```
+
+### SafeUser
+
+```typescript
+type SafeUser = Omit<UserEntity, 'passwordHash'>
+```
+
+### CreateUserParams
+
+```typescript
+interface CreateUserParams {
+    username: string
+    password: string
+    email?: string
+    displayName?: string
+    roles?: string[]
+}
+```
+
+## 密码工具
+
+独立的密码工具函数：
+
+```typescript
+import { hashPassword, verifyPassword } from '@esengine/database'
+
+// 哈希密码
+const hash = await hashPassword('myPassword123')
+
+// 验证密码
+const isValid = await verifyPassword('myPassword123', hash)
+```
+
+### 安全说明
+
+- 使用 Node.js 内置的 `scrypt` 算法
+- 自动生成随机盐值
+- 默认使用安全的迭代参数
+- 哈希格式：`salt:hash`（均为 hex 编码）
+
+## 扩展 UserRepository
+
+```typescript
+import { UserRepository, UserEntity } from '@esengine/database'
+
+interface GameUser extends UserEntity {
+    level: number
+    experience: number
+    coins: number
+}
+
+class GameUserRepository extends UserRepository {
+    // 重写集合名
+    constructor(connection: IMongoConnection) {
+        super(connection, 'game_users')
+    }
+
+    // 添加游戏相关方法
+    async addExperience(userId: string, amount: number): Promise<GameUser | null> {
+        const user = await this.findById(userId) as GameUser | null
+        if (!user) return null
+
+        const newExp = user.experience + amount
+        const newLevel = Math.floor(newExp / 1000) + 1
+
+        return this.update(userId, {
+            experience: newExp,
+            level: newLevel
+        }) as Promise<GameUser | null>
+    }
+
+    async findTopPlayers(limit: number = 10): Promise<GameUser[]> {
+        return this.findMany({
+            sort: { level: 'desc', experience: 'desc' },
+            limit
+        }) as Promise<GameUser[]>
+    }
+}
+```

+title: "认证系统"
+description: "使用 JWT 和 Session 提供者为游戏服务器添加认证功能"
+---
+
+`@esengine/server` 包内置了可插拔的认证系统，支持 JWT、会话认证和自定义提供者。
+
+## 安装
+
+认证功能已包含在 server 包中：
+
+```bash
+npm install @esengine/server jsonwebtoken
+```
+
+> 注意：`jsonwebtoken` 是可选的 peer dependency，仅在使用 JWT 认证时需要。
+
+## 快速开始
+
+### JWT 认证
+
+```typescript
+import { createServer } from '@esengine/server'
+import { withAuth, createJwtAuthProvider, withRoomAuth, requireAuth } from '@esengine/server/auth'
+
+// 创建 JWT 提供者
+const jwtProvider = createJwtAuthProvider({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600, // 1 小时
+})
+
+// 用认证包装服务器
+const server = withAuth(await createServer({ port: 3000 }), {
+    provider: jwtProvider,
+    extractCredentials: (req) => {
+        const url = new URL(req.url ?? '', 'http://localhost')
+        return url.searchParams.get('token')
+    },
+})
+
+// 定义需要认证的房间
+class GameRoom extends withRoomAuth(Room, { requireAuth: true }) {
+    onJoin(player) {
+        console.log(`${player.user?.name} 加入了游戏！`)
+    }
+}
+
+server.define('game', GameRoom)
+await server.start()
+```
+
+## 认证提供者
+
+### JWT 提供者
+
+使用 JSON Web Tokens 实现无状态认证：
+
+```typescript
+import { createJwtAuthProvider } from '@esengine/server/auth'
+
+const jwtProvider = createJwtAuthProvider({
+    // 必填：密钥
+    secret: 'your-secret-key',
+
+    // 可选：算法（默认：HS256）
+    algorithm: 'HS256',
+
+    // 可选：过期时间（秒，默认：3600）
+    expiresIn: 3600,
+
+    // 可选：签发者（用于验证）
+    issuer: 'my-game-server',
+
+    // 可选：受众（用于验证）
+    audience: 'my-game-client',
+
+    // 可选：自定义用户提取
+    getUser: async (payload) => {
+        // 从数据库获取用户
+        return await db.users.findById(payload.sub)
+    },
+})
+
+// 签发令牌（用于登录接口）
+const token = jwtProvider.sign({
+    sub: user.id,
+    name: user.name,
+    roles: ['player'],
+})
+
+// 解码但不验证（用于调试）
+const payload = jwtProvider.decode(token)
+```
+
+### 自定义提供者
+
+你可以通过实现 `IAuthProvider` 接口来创建自定义认证提供者，以集成任何认证系统（如 OAuth、LDAP、自定义数据库认证等）。
+
+#### IAuthProvider 接口
+
+```typescript
+interface IAuthProvider<TUser = unknown, TCredentials = unknown> {
+    /** 提供者名称 */
+    readonly name: string;
+
+    /** 验证凭证 */
+    verify(credentials: TCredentials): Promise<AuthResult<TUser>>;
+
+    /** 刷新令牌（可选） */
+    refresh?(token: string): Promise<AuthResult<TUser>>;
+
+    /** 撤销令牌（可选） */
+    revoke?(token: string): Promise<boolean>;
+}
+
+interface AuthResult<TUser> {
+    success: boolean;
+    user?: TUser;
+    error?: string;
+    errorCode?: AuthErrorCode;
+    token?: string;
+    expiresAt?: number;
+}
+
+type AuthErrorCode =
+    | 'INVALID_CREDENTIALS'
+    | 'EXPIRED_TOKEN'
+    | 'INVALID_TOKEN'
+    | 'USER_NOT_FOUND'
+    | 'ACCOUNT_DISABLED'
+    | 'RATE_LIMITED'
+    | 'INSUFFICIENT_PERMISSIONS';
+```
+
+#### 自定义提供者示例
+
+**示例 1：数据库密码认证**
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface User {
+    id: string
+    username: string

+}
+
+class DatabaseAuthProvider implements IAuthProvider<User, PasswordCredentials> {
+    readonly name = 'database'
+
+    async verify(credentials: PasswordCredentials): Promise<AuthResult<User>> {
+        const { username, password } = credentials
+
+        // 从数据库查询用户
+        const user = await db.users.findByUsername(username)
+        if (!user) {
+            return {

+                errorCode: 'USER_NOT_FOUND'
+            }
+        }
+
+        // 验证密码（使用 bcrypt 等库）
+        const isValid = await bcrypt.compare(password, user.passwordHash)
+        if (!isValid) {
+            return {
+                success: false,
+                error: '密码错误',
+                errorCode: 'INVALID_CREDENTIALS'
+            }
+        }
+
+        // 检查账号状态
+        if (user.disabled) {
+            return {
+                success: false,
+                error: '账号已禁用',
+                errorCode: 'ACCOUNT_DISABLED'
+            }
+        }
+
+        return {
+            success: true,
+            user: {
+                id: user.id,
+                username: user.username,
+                roles: user.roles
+            }
+        }
+    }
+}
+```
+
+**示例 2：OAuth/第三方认证**
+
+```typescript

+            case 'google':
+                return fetch('https://www.googleapis.com/oauth2/v2/userinfo', {
+                    headers: { Authorization: `Bearer ${token}` }
+                }).then(r => r.json())

+            // 其他提供商...
+            default:
+                throw new Error(`不支持的提供商: ${provider}`)
+        }
+    }
+}
+```
+
+**示例 3：API Key 认证**
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface ApiUser {
+    id: string
+    name: string
+    roles: string[]
+    rateLimit: number
+}
+
+class ApiKeyAuthProvider implements IAuthProvider<ApiUser, string> {
+    readonly name = 'api-key'
+
+    private revokedKeys = new Set<string>()
+
+    async verify(apiKey: string): Promise<AuthResult<ApiUser>> {
+        if (!apiKey || !apiKey.startsWith('sk_')) {
+            return {
+                success: false,
+                error: 'API Key 格式无效',
+                errorCode: 'INVALID_TOKEN'
+            }
+        }
+
+        if (this.revokedKeys.has(apiKey)) {
+            return {
+                success: false,
+                error: 'API Key 已被撤销',
+                errorCode: 'INVALID_TOKEN'
+            }
+        }
+
+        // 从数据库查询 API Key
+        const keyData = await db.apiKeys.findByKey(apiKey)
+        if (!keyData) {
+            return {
+                success: false,
+                error: 'API Key 不存在',
+                errorCode: 'INVALID_CREDENTIALS'
+            }
+        }
+
+        // 检查过期
+        if (keyData.expiresAt && keyData.expiresAt < Date.now()) {
+            return {
+                success: false,
+                error: 'API Key 已过期',
+                errorCode: 'EXPIRED_TOKEN'
+            }
+        }
+
+        return {
+            success: true,
+            user: {
+                id: keyData.userId,
+                name: keyData.name,
+                roles: keyData.roles,
+                rateLimit: keyData.rateLimit
+            },
+            expiresAt: keyData.expiresAt
+        }
+    }
+
+    async revoke(apiKey: string): Promise<boolean> {
+        this.revokedKeys.add(apiKey)
+        await db.apiKeys.revoke(apiKey)
+        return true
+    }
+}
+```
+
+#### 使用自定义提供者
+
+```typescript
+import { createServer } from '@esengine/server'
+import { withAuth } from '@esengine/server/auth'
+
+// 创建自定义提供者
+const dbAuthProvider = new DatabaseAuthProvider()
+
+// 或使用 OAuth 提供者
+const oauthProvider = new OAuthProvider()
+
+// 使用自定义提供者
+const server = withAuth(await createServer({ port: 3000 }), {
+    provider: dbAuthProvider, // 或 oauthProvider
+
+    // 从 WebSocket 连接请求中提取凭证
+    extractCredentials: (req) => {
+        const url = new URL(req.url, 'http://localhost')
+
+        // 对于数据库认证：从查询参数获取
+        const username = url.searchParams.get('username')
+        const password = url.searchParams.get('password')
+        if (username && password) {
+            return { username, password }
+        }
+
+        // 对于 OAuth：从 token 参数获取
+        const provider = url.searchParams.get('provider')
+        const accessToken = url.searchParams.get('access_token')
+        if (provider && accessToken) {
+            return { provider, accessToken }
+        }
+
+        // 对于 API Key：从请求头获取
+        const apiKey = req.headers['x-api-key']
+        if (apiKey) {
+            return apiKey as string
+        }
+
+        return null
+    },
+
+    onAuthFailure: (conn, error) => {
+        console.log(`认证失败: ${error.errorCode} - ${error.error}`)
+    }
+})
+
+await server.start()
+```
+
+#### 组合多个提供者
+
+你可以创建一个复合提供者来支持多种认证方式：
+
+```typescript
+import type { IAuthProvider, AuthResult } from '@esengine/server/auth'
+
+interface MultiAuthCredentials {
+    type: 'jwt' | 'oauth' | 'apikey' | 'password'
+    data: unknown
+}
+
+class MultiAuthProvider implements IAuthProvider<User, MultiAuthCredentials> {
+    readonly name = 'multi'
+
+    constructor(
+        private jwtProvider: JwtAuthProvider<User>,
+        private oauthProvider: OAuthProvider,
+        private apiKeyProvider: ApiKeyAuthProvider,
+        private dbProvider: DatabaseAuthProvider
+    ) {}
+
+    async verify(credentials: MultiAuthCredentials): Promise<AuthResult<User>> {
+        switch (credentials.type) {
+            case 'jwt':
+                return this.jwtProvider.verify(credentials.data as string)
+            case 'oauth':
+                return this.oauthProvider.verify(credentials.data as OAuthCredentials)
+            case 'apikey':
+                return this.apiKeyProvider.verify(credentials.data as string)
+            case 'password':
+                return this.dbProvider.verify(credentials.data as PasswordCredentials)
+            default:
+                return {
+                    success: false,
+                    error: '不支持的认证类型',
+                    errorCode: 'INVALID_CREDENTIALS'
+                }
+        }
+    }
+}
+```
+
+### Session 提供者
+
+使用服务端会话实现有状态认证：
+
+```typescript
+import { createSessionAuthProvider, type ISessionStorage } from '@esengine/server/auth'
+
+// 自定义存储实现
+const storage: ISessionStorage = {
+    async get<T>(key: string): Promise<T | null> {
+        return await redis.get(key)
+    },
+    async set<T>(key: string, value: T): Promise<void> {
+        await redis.set(key, value)
+    },
+    async delete(key: string): Promise<boolean> {
+        return await redis.del(key) > 0
+    },
+}
+
+const sessionProvider = createSessionAuthProvider({
+    storage,
+    sessionTTL: 86400000, // 24 小时（毫秒）
+
+    // 可选：每次请求时验证用户
+    validateUser: (user) => !user.banned,
+})
+
+// 创建会话（用于登录接口）
+const sessionId = await sessionProvider.createSession(user, {
+    ipAddress: req.ip,
+    userAgent: req.headers['user-agent'],
+})
+
+// 撤销会话（用于登出）
+await sessionProvider.revoke(sessionId)
+```
+
+## 服务器认证 Mixin
+
+`withAuth` 函数用于包装服务器添加认证功能：
+
+```typescript
+import { withAuth } from '@esengine/server/auth'
+
+const server = withAuth(baseServer, {
+    // 必填：认证提供者
+    provider: jwtProvider,
+
+    // 必填：从请求中提取凭证
+    extractCredentials: (req) => {
+        // 从查询字符串获取
+        return new URL(req.url, 'http://localhost').searchParams.get('token')
+
+        // 或从请求头获取
+        // return req.headers['authorization']?.replace('Bearer ', '')
+    },
+
+    // 可选：处理认证失败
+    onAuthFailed: (conn, error) => {
+        console.log(`认证失败: ${error}`)
+    },
+})
+```
+
+### 访问认证上下文
+
+认证后，可以从连接获取认证上下文：
+
+```typescript
+import { getAuthContext } from '@esengine/server/auth'
+
+server.onConnect = (conn) => {
+    const auth = getAuthContext(conn)
+
+    if (auth.isAuthenticated) {
+        console.log(`用户 ${auth.userId} 已连接`)
+        console.log(`角色: ${auth.roles}`)
+    }
+}
+```
+
+## 房间认证 Mixin
+
+`withRoomAuth` 函数为房间添加认证检查：
+
+```typescript
+import { withRoomAuth, type AuthPlayer } from '@esengine/server/auth'
+
+interface User {
+    id: string
+    name: string
+    roles: string[]
+}
+
+class GameRoom extends withRoomAuth<User>(Room, {
+    // 要求认证才能加入
+    requireAuth: true,
+
+    // 可选：要求特定角色
+    allowedRoles: ['player', 'premium'],
+
+    // 可选：角色检查模式（'any' 或 'all'）
+    roleCheckMode: 'any',
+}) {
+    // player 拥有 .auth 和 .user 属性
+    onJoin(player: AuthPlayer<User>) {
+        console.log(`${player.user?.name} 加入了`)
+        console.log(`是否高级会员: ${player.auth.hasRole('premium')}`)
+    }
+
+    // 可选：自定义认证验证
+    async onAuth(player: AuthPlayer<User>): Promise<boolean> {
+        // 额外的验证逻辑
+        if (player.auth.hasRole('banned')) {
+            return false
+        }
+        return true
+    }
+
+    @onMessage('Chat')
+    handleChat(data: { text: string }, player: AuthPlayer<User>) {
+        this.broadcast('Chat', {
+            from: player.user?.name ?? '访客',
+            text: data.text,
+        })
+    }
+}
+```
+
+### AuthPlayer 接口
+
+认证房间中的玩家拥有额外属性：
+
+```typescript
+interface AuthPlayer<TUser> extends Player {
+    // 完整认证上下文
+    readonly auth: IAuthContext<TUser>
+
+    // 用户信息（auth.user 的快捷方式）
+    readonly user: TUser | null
+}
+```
+
+### 房间认证辅助方法
+
+```typescript
+class GameRoom extends withRoomAuth<User>(Room) {
+    someMethod() {
+        // 通过用户 ID 获取玩家
+        const player = this.getPlayerByUserId('user-123')
+
+        // 获取拥有特定角色的所有玩家
+        const admins = this.getPlayersByRole('admin')
+
+        // 获取带认证信息的玩家
+        const authPlayer = this.getAuthPlayer(playerId)
+    }
+}
+```
+
+## 认证装饰器
+
+### @requireAuth
+
+标记消息处理器需要认证：
+
+```typescript
+import { requireAuth, requireRole, onMessage } from '@esengine/server/auth'
+
+class GameRoom extends withRoomAuth(Room) {
+    @requireAuth()
+    @onMessage('Trade')
+    handleTrade(data: TradeData, player: AuthPlayer) {
+        // 只有已认证玩家才能交易
+    }
+
+    @requireAuth({ allowGuest: true })
+    @onMessage('Chat')
+    handleChat(data: ChatData, player: AuthPlayer) {
+        // 访客也可以聊天
+    }
+}
+```
+
+### @requireRole
+
+要求特定角色才能访问消息处理器：
+
+```typescript
+class AdminRoom extends withRoomAuth(Room) {
+    @requireRole('admin')
+    @onMessage('Ban')
+    handleBan(data: BanData, player: AuthPlayer) {
+        // 只有管理员才能封禁
+    }
+
+    @requireRole(['moderator', 'admin'])
+    @onMessage('Mute')
+    handleMute(data: MuteData, player: AuthPlayer) {
+        // 版主或管理员可以禁言
+    }
+
+    @requireRole(['verified', 'premium'], { mode: 'all' })
+    @onMessage('SpecialFeature')
+    handleSpecial(data: any, player: AuthPlayer) {
+        // 需要同时拥有 verified 和 premium 角色
+    }
+}
+```
+
+## 认证上下文 API
+
+认证上下文提供多种检查认证状态的方法：
+
+```typescript
+interface IAuthContext<TUser> {
+    // 认证状态
+    readonly isAuthenticated: boolean
+    readonly user: TUser | null
+    readonly userId: string | null
+    readonly roles: ReadonlyArray<string>
+    readonly authenticatedAt: number | null
+    readonly expiresAt: number | null
+
+    // 角色检查
+    hasRole(role: string): boolean
+    hasAnyRole(roles: string[]): boolean
+    hasAllRoles(roles: string[]): boolean
+}
+```
+
+`AuthContext` 类（实现类）还提供：
+
+```typescript
+class AuthContext<TUser> implements IAuthContext<TUser> {
+    // 从认证结果设置认证状态
+    setAuthenticated(result: AuthResult<TUser>): void
+
+    // 清除认证状态
+    clear(): void
+}
+```
+
+## 测试
+
+使用模拟认证提供者进行单元测试：
+
+```typescript
+import { createMockAuthProvider } from '@esengine/server/auth/testing'
+
+// 创建带预设用户的模拟提供者
+const mockProvider = createMockAuthProvider({
+    users: [
+        { id: '1', name: 'Alice', roles: ['player'] },
+        { id: '2', name: 'Bob', roles: ['admin', 'player'] },
+    ],
+    autoCreate: true, // 为未知令牌创建用户
+})
+
+// 在测试中使用
+const server = withAuth(testServer, {
+    provider: mockProvider,
+    extractCredentials: (req) => req.headers['x-token'],
+})
+
+// 使用用户 ID 作为令牌进行验证
+const result = await mockProvider.verify('1')
+// result.user = { id: '1', name: 'Alice', roles: ['player'] }
+
+// 动态添加/移除用户
+mockProvider.addUser({ id: '3', name: 'Charlie', roles: ['guest'] })
+mockProvider.removeUser('3')
+
+// 撤销令牌
+await mockProvider.revoke('1')
+
+// 重置到初始状态
+mockProvider.clear()
+```
+
+## 错误处理
+
+认证错误包含错误码用于程序化处理：
+
+```typescript
+type AuthErrorCode =
+    | 'INVALID_CREDENTIALS'       // 用户名/密码无效
+    | 'INVALID_TOKEN'             // 令牌格式错误或无效
+    | 'EXPIRED_TOKEN'             // 令牌已过期
+    | 'USER_NOT_FOUND'            // 用户查找失败
+    | 'ACCOUNT_DISABLED'          // 用户账号已禁用
+    | 'RATE_LIMITED'              // 请求过于频繁
+    | 'INSUFFICIENT_PERMISSIONS'  // 权限不足
+
+// 在认证失败处理器中
+const server = withAuth(baseServer, {
+    provider: jwtProvider,
+    extractCredentials,
+    onAuthFailed: (conn, error) => {
+        switch (error.errorCode) {
+            case 'EXPIRED_TOKEN':
+                conn.send('AuthError', { code: 'TOKEN_EXPIRED' })
+                break
+            case 'INVALID_TOKEN':
+                conn.send('AuthError', { code: 'INVALID_TOKEN' })
+                break
+            default:
+                conn.close()
+        }
+    },
+})
+```
+
+## 完整示例
+
+以下是使用 JWT 认证的完整示例：
+
+```typescript
+// server.ts
+import { createServer } from '@esengine/server'
+import {
+    withAuth,
+    withRoomAuth,
+    createJwtAuthProvider,
+    requireAuth,
+    requireRole,
+    type AuthPlayer,
+} from '@esengine/server/auth'
+
+// 类型定义
+interface User {
+    id: string
+    name: string
+    roles: string[]
+}
+
+// JWT 提供者
+const jwtProvider = createJwtAuthProvider<User>({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600,
+    getUser: async (payload) => ({
+        id: payload.sub as string,
+        name: payload.name as string,
+        roles: (payload.roles as string[]) ?? [],
+    }),
+})
+
+// 创建带认证的服务器
+const server = withAuth(
+    await createServer({ port: 3000 }),
+    {
+        provider: jwtProvider,
+        extractCredentials: (req) => {
+            return new URL(req.url ?? '', 'http://localhost')
+                .searchParams.get('token')
+        },
+    }
+)
+
+// 带认证的游戏房间
+class GameRoom extends withRoomAuth<User>(Room, {
+    requireAuth: true,
+    allowedRoles: ['player'],
+}) {
+    onCreate() {
+        console.log('游戏房间已创建')
+    }
+
+    onJoin(player: AuthPlayer<User>) {
+        console.log(`${player.user?.name} 加入了！`)
+        this.broadcast('PlayerJoined', {
+            id: player.id,
+            name: player.user?.name,
+        })
+    }
+
+    @requireAuth()
+    @onMessage('Move')
+    handleMove(data: { x: number; y: number }, player: AuthPlayer<User>) {
+        // 处理移动
+    }
+
+    @requireRole('admin')
+    @onMessage('Kick')
+    handleKick(data: { playerId: string }, player: AuthPlayer<User>) {
+        const target = this.getPlayer(data.playerId)
+        if (target) {
+            this.kick(target, '被管理员踢出')
+        }
+    }
+}
+
+server.define('game', GameRoom)
+await server.start()
+```
+
+## 最佳实践
+
+1. **保护密钥安全**：永远不要硬编码 JWT 密钥，使用环境变量。
+
+2. **设置合理的过期时间**：在安全性和用户体验之间平衡令牌 TTL。
+
+3. **在关键操作上验证**：在敏感消息处理器上使用 `@requireAuth`。
+
+4. **使用基于角色的访问控制**：为管理功能实现适当的角色层级。
+
+5. **处理令牌刷新**：为长会话实现令牌刷新逻辑。
+
+6. **记录认证事件**：跟踪登录尝试和失败以进行安全监控。
+
+7. **测试认证流程**：使用 `MockAuthProvider` 测试认证场景。

+description: "使用可配置的速率限制保护你的游戏服务器免受滥用"
+---
+
+`@esengine/server` 包含可插拔的速率限制系统，用于防止 DDoS 攻击、消息洪水和其他滥用行为。
+
+## 安装
+
+速率限制包含在 server 包中：
+
+```bash
+npm install @esengine/server
+```
+
+## 快速开始
+
+```typescript
+import { Room, onMessage } from '@esengine/server'
+import { withRateLimit, rateLimit, noRateLimit } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room, {
+    messagesPerSecond: 10,
+    burstSize: 20,
+    onLimited: (player, type, result) => {
+        player.send('Error', {
+            code: 'RATE_LIMITED',
+            retryAfter: result.retryAfter,
+        })
+    },
+}) {
+    @onMessage('Move')
+    handleMove(data: { x: number; y: number }, player: Player) {
+        // 受速率限制保护（默认 10 msg/s）
+    }
+
+    @rateLimit({ messagesPerSecond: 1 })
+    @onMessage('Trade')
+    handleTrade(data: TradeData, player: Player) {
+        // 交易使用更严格的限制
+    }
+
+    @noRateLimit()
+    @onMessage('Heartbeat')
+    handleHeartbeat(data: any, player: Player) {
+        // 心跳不限制
+    }
+}
+```
+
+## 速率限制策略
+
+### 令牌桶（默认）
+
+令牌桶算法允许突发流量，同时保持长期速率限制。令牌以固定速率添加，每个请求消耗令牌。
+
+```typescript
+import { withRateLimit } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room, {
+    strategy: 'token-bucket',
+    messagesPerSecond: 10, // 补充速率
+    burstSize: 20,         // 桶容量
+}) { }
+```
+
+**工作原理：**
+```
+配置: rate=10/s, burstSize=20
+
+[0s]   桶满: 20 令牌
+[0s]   收到 15 条消息 → 允许，剩余 5
+[0.5s] 补充 5 令牌 → 10 令牌
+[0.5s] 收到 8 条消息 → 允许，剩余 2
+[0.6s] 补充 1 令牌 → 3 令牌
+[0.6s] 收到 5 条消息 → 允许 3，拒绝 2
+```
+
+**最适合：** 大多数通用场景，平衡突发容忍度与保护。

+滑动窗口算法精确跟踪时间窗口内的请求。比固定窗口更准确，但内存使用稍多。
+
+```typescript
+class GameRoom extends withRateLimit(Room, {
+    strategy: 'sliding-window',
+    messagesPerSecond: 10,
+    burstSize: 10,
+}) { }
+```
+
+**最适合：** 需要精确限流且不需要突发容忍的场景。
+
+### 固定窗口
+
+固定窗口算法将时间划分为固定间隔，并计算每个间隔内的请求数。简单且内存高效，但在窗口边界允许 2 倍突发。
+
+```typescript
+class GameRoom extends withRateLimit(Room, {
+    strategy: 'fixed-window',
+    messagesPerSecond: 10,
+    burstSize: 10,
+}) { }
+```
+
+**最适合：** 简单场景，可接受边界突发。
+
+## 配置
+
+### 房间配置
+
+```typescript
+import { withRateLimit } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room, {
+    // 每秒允许的消息数（默认: 10）
+    messagesPerSecond: 10,
+
+    // 突发容量 / 桶大小（默认: 20）
+    burstSize: 20,
+
+    // 策略: 'token-bucket' | 'sliding-window' | 'fixed-window'
+    strategy: 'token-bucket',
+
+    // 被限流时的回调
+    onLimited: (player, messageType, result) => {
+        player.send('RateLimited', {
+            type: messageType,
+            retryAfter: result.retryAfter,
+        })
+    },
+
+    // 限流时断开连接（默认: false）
+    disconnectOnLimit: false,
+
+    // 连续 N 次限流后断开（0 = 永不）
+    maxConsecutiveLimits: 10,
+
+    // 自定义键函数（默认: player.id）
+    getKey: (player) => player.id,
+
+    // 清理间隔（毫秒，默认: 60000）
+    cleanupInterval: 60000,
+}) { }
+```
+
+### 单消息配置
+
+使用装饰器为特定消息配置速率限制：
+
+```typescript
+import { rateLimit, noRateLimit, rateLimitMessage } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room) {
+    // 此消息使用自定义速率限制
+    @rateLimit({ messagesPerSecond: 1, burstSize: 2 })
+    @onMessage('Trade')
+    handleTrade(data: TradeData, player: Player) { }
+
+    // 此消息消耗 5 个令牌
+    @rateLimit({ cost: 5 })
+    @onMessage('ExpensiveAction')
+    handleExpensive(data: any, player: Player) { }
+
+    // 豁免速率限制
+    @noRateLimit()
+    @onMessage('Heartbeat')
+    handleHeartbeat(data: any, player: Player) { }
+
+    // 替代方案：显式指定消息类型
+    @rateLimitMessage('SpecialAction', { messagesPerSecond: 2 })
+    @onMessage('SpecialAction')
+    handleSpecial(data: any, player: Player) { }
+}
+```
+
+## 与认证系统组合
+
+速率限制可与认证系统无缝配合：
+
+```typescript
+import { withRoomAuth } from '@esengine/server/auth'
+import { withRateLimit } from '@esengine/server/ratelimit'
+
+// 同时应用两个 mixin
+class GameRoom extends withRateLimit(
+    withRoomAuth(Room, { requireAuth: true }),
+    { messagesPerSecond: 10 }
+) {
+    onJoin(player: AuthPlayer) {
+        console.log(`${player.user?.name} 已加入，受速率限制保护`)
+    }
+}
+```
+
+## 速率限制结果
+
+当消息被限流时，回调会收到结果对象：
+
+```typescript
+interface RateLimitResult {
+    // 是否允许请求
+    allowed: boolean
+
+    // 剩余配额
+    remaining: number
+
+    // 配额重置时间（时间戳）
+    resetAt: number
+
+    // 重试等待时间（毫秒）
+    retryAfter?: number
+}
+```
+
+## 访问速率限制上下文
+
+你可以访问任何玩家的速率限制上下文：
+
+```typescript
+import { getPlayerRateLimitContext } from '@esengine/server/ratelimit'
+
+class GameRoom extends withRateLimit(Room) {
+    someMethod(player: Player) {
+        const context = this.getRateLimitContext(player)
+
+        // 检查但不消费
+        const status = context?.check()
+        console.log(`剩余: ${status?.remaining}`)
+
+        // 获取连续限流次数
+        console.log(`连续限流: ${context?.consecutiveLimitCount}`)
+    }
+}
+
+// 或使用独立函数
+const context = getPlayerRateLimitContext(player)
+```
+
+## 自定义策略
+
+你可以直接使用策略进行自定义实现：
+
+```typescript
+import {
+    TokenBucketStrategy,
+    SlidingWindowStrategy,
+    FixedWindowStrategy,
+    createTokenBucketStrategy,
+} from '@esengine/server/ratelimit'
+
+// 直接创建策略
+const strategy = createTokenBucketStrategy({
+    rate: 10,      // 每秒令牌数
+    capacity: 20,  // 最大令牌数
+})
+
+// 检查并消费
+const result = strategy.consume('player-123')
+if (result.allowed) {
+    // 处理消息
+} else {
+    // 被限流，等待 result.retryAfter 毫秒
+}
+
+// 检查但不消费
+const status = strategy.getStatus('player-123')
+
+// 重置某个键
+strategy.reset('player-123')
+
+// 清理过期记录
+strategy.cleanup()
+```
+
+## 速率限制上下文
+
+`RateLimitContext` 类管理单个玩家的速率限制：
+
+```typescript
+import { RateLimitContext, TokenBucketStrategy } from '@esengine/server/ratelimit'
+
+const strategy = new TokenBucketStrategy({ rate: 10, capacity: 20 })
+const context = new RateLimitContext('player-123', strategy)
+
+// 检查但不消费
+context.check()
+
+// 消费配额
+context.consume()
+
+// 带消耗量消费
+context.consume(undefined, 5)
+
+// 为特定消息类型消费
+context.consume('Trade')
+
+// 设置单消息策略
+context.setMessageStrategy('Trade', new TokenBucketStrategy({ rate: 1, capacity: 2 }))
+
+// 重置
+context.reset()
+
+// 获取连续限流次数
+console.log(context.consecutiveLimitCount)
+```
+
+## 房间生命周期钩子
+
+你可以重写 `onRateLimited` 钩子进行自定义处理：
+
+```typescript
+class GameRoom extends withRateLimit(Room) {
+    onRateLimited(player: Player, messageType: string, result: RateLimitResult) {
+        // 记录事件
+        console.log(`玩家 ${player.id} 在 ${messageType} 上被限流`)
+
+        // 发送自定义错误
+        player.send('SystemMessage', {
+            type: 'warning',
+            message: `请慢一点！${result.retryAfter}ms 后重试`,
+        })
+    }
+}
+```
+
+## 最佳实践
+
+1. **从令牌桶开始**：对于游戏来说是最灵活的算法。
+
+2. **设置合适的限制**：考虑你的游戏机制：
+   - 移动消息：较高限制（20-60/s）
+   - 聊天消息：较低限制（1-5/s）
+   - 交易/购买：非常低的限制（0.5-1/s）
+
+3. **使用突发容量**：允许短暂突发以获得响应式体验：
+   ```typescript
+   messagesPerSecond: 10,
+   burstSize: 30, // 允许 3 秒的突发
+   ```
+
+4. **豁免关键消息**：不要限制心跳或系统消息：
+   ```typescript
+   @noRateLimit()
+   @onMessage('Heartbeat')
+   handleHeartbeat() { }
+   ```
+
+5. **与认证结合**：对已认证用户按用户 ID 限流：
+   ```typescript
+   getKey: (player) => player.auth?.userId ?? player.id
+   ```
+
+6. **监控和调整**：记录限流事件以调整限制：
+   ```typescript
+   onLimited: (player, type, result) => {
+       metrics.increment('rate_limit', { messageType: type })
+   }
+   ```
+
+7. **优雅降级**：发送信息性错误而不是直接断开：
+   ```typescript
+   onLimited: (player, type, result) => {
+       player.send('Error', {
+           code: 'RATE_LIMITED',
+           message: '请求过于频繁',
+           retryAfter: result.retryAfter,
+       })
+   }
+   ```
+

+## HTTP 路由
+
+支持 HTTP API 与 WebSocket 共用端口，适用于登录、注册等场景。
+
+### 文件路由
+
+在 `httpDir` 目录下创建路由文件，自动映射为 HTTP 端点：
+
+```
+src/http/
+├── login.ts       → POST /api/login
+├── register.ts    → POST /api/register
+├── health.ts      → GET  /api/health (需设置 method: 'GET')
+└── users/
+    └── [id].ts    → POST /api/users/:id (动态路由)
+```
+
+### 定义路由
+
+使用 `defineHttp` 定义类型安全的路由处理器：
+
+```typescript
+// src/http/login.ts
+import { defineHttp } from '@esengine/server'
+
+interface LoginBody {
+    username: string
+    password: string
+}
+
+export default defineHttp<LoginBody>({
+    method: 'POST',  // 默认 POST，可选 GET/PUT/DELETE/PATCH
+    handler(req, res) {
+        const { username, password } = req.body
+
+        // 验证凭证...
+        if (!isValid(username, password)) {
+            res.error(401, 'Invalid credentials')
+            return
+        }
+
+        // 生成 token...
+        res.json({ token: '...', userId: '...' })
+    }
+})
+```
+
+### 请求对象 (HttpRequest)
+
+```typescript
+interface HttpRequest {
+    raw: IncomingMessage     // Node.js 原始请求
+    method: string           // 请求方法
+    path: string             // 请求路径
+    query: Record<string, string>  // 查询参数
+    headers: Record<string, string | string[] | undefined>
+    body: unknown            // 解析后的 JSON 请求体
+    ip: string               // 客户端 IP
+}
+```
+
+### 响应对象 (HttpResponse)
+
+```typescript
+interface HttpResponse {
+    raw: ServerResponse      // Node.js 原始响应
+    status(code: number): HttpResponse   // 设置状态码（链式）
+    header(name: string, value: string): HttpResponse  // 设置头（链式）
+    json(data: unknown): void            // 发送 JSON
+    text(data: string): void             // 发送文本
+    error(code: number, message: string): void  // 发送错误
+}
+```
+
+### 使用示例
+
+```typescript
+// 完整的登录服务器示例
+import { createServer, defineHttp } from '@esengine/server'
+import { createJwtAuthProvider, withAuth } from '@esengine/server/auth'
+
+const jwtProvider = createJwtAuthProvider({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600 * 24,
+})
+
+const server = await createServer({
+    port: 8080,
+    httpDir: 'src/http',
+    httpPrefix: '/api',
+    cors: true,
+})
+
+// 包装认证（WebSocket 连接验证 token）
+const authServer = withAuth(server, {
+    provider: jwtProvider,
+    extractCredentials: (req) => {
+        const url = new URL(req.url, 'http://localhost')
+        return url.searchParams.get('token')
+    },
+})
+
+await authServer.start()
+// HTTP: http://localhost:8080/api/*
+// WebSocket: ws://localhost:8080?token=xxx
+```
+
+### 内联路由
+
+也可以直接在配置中定义路由（与文件路由合并，内联优先）：
+
+```typescript
+const server = await createServer({
+    port: 8080,
+    http: {
+        '/health': {
+            GET: (req, res) => res.json({ status: 'ok' }),
+        },
+        '/webhook': async (req, res) => {
+            // 接受所有方法
+            await handleWebhook(req.body)
+            res.json({ received: true })
+        },
+    },
+})

+## @NetworkEntity 装饰器
+
+`@NetworkEntity` 装饰器用于标记需要自动广播生成/销毁的组件。当包含此组件的实体被创建或销毁时，ECSRoom 会自动广播相应的消息给所有客户端。
+
+### 基本用法
+
+```typescript
+import { Component, ECSComponent, sync, NetworkEntity } from '@esengine/ecs-framework';
+
+@ECSComponent('Enemy')
+@NetworkEntity('Enemy')
+class EnemyComponent extends Component {
+    @sync('float32') x: number = 0;
+    @sync('float32') y: number = 0;
+    @sync('uint16') health: number = 100;
+}
+```
+
+当添加此组件到实体时，ECSRoom 会自动广播 spawn 消息：
+
+```typescript
+// 服务端
+const entity = scene.createEntity('Enemy');
+entity.addComponent(new EnemyComponent()); // 自动广播 spawn
+
+// 销毁时自动广播 despawn
+entity.destroy(); // 自动广播 despawn
+```
+
+### 配置选项
+
+```typescript
+@NetworkEntity('Bullet', {
+    autoSpawn: true,    // 自动广播生成（默认 true）
+    autoDespawn: false  // 禁用自动广播销毁
+})
+class BulletComponent extends Component { }
+```
+
+| 选项 | 类型 | 默认值 | 描述 |
+|------|------|--------|------|
+| `autoSpawn` | `boolean` | `true` | 添加组件时自动广播 spawn |
+| `autoDespawn` | `boolean` | `true` | 销毁实体时自动广播 despawn |
+
+### 初始化顺序
+
+使用 `@NetworkEntity` 时，应在添加组件**之前**初始化数据：
+
+```typescript
+// ✅ 正确：先初始化，再添加
+const comp = new PlayerComponent();
+comp.playerId = player.id;
+comp.x = 100;
+comp.y = 200;
+entity.addComponent(comp); // spawn 时数据已正确
+
+// ❌ 错误：先添加，再初始化
+const comp = entity.addComponent(new PlayerComponent());
+comp.playerId = player.id; // spawn 时数据是默认值
+```
+
+### 简化 GameRoom
+
+使用 `@NetworkEntity` 后，GameRoom 变得更加简洁：
+
+```typescript
+// 无需手动回调
+class GameRoom extends ECSRoom {
+    private setupSystems(): void {
+        // 敌人生成系统（自动广播 spawn）
+        this.addSystem(new EnemySpawnSystem());
+
+        // 敌人 AI 系统
+        const enemyAI = new EnemyAISystem();
+        enemyAI.onDeath((enemy) => {
+            enemy.destroy(); // 自动广播 despawn
+        });
+        this.addSystem(enemyAI);
+    }
+}
+```
+
+### ECSRoom 配置
+
+可以在 ECSRoom 中禁用自动网络实体功能：
+
+```typescript
+class GameRoom extends ECSRoom {
+    constructor() {
+        super({
+            enableAutoNetworkEntity: false // 禁用自动广播
+        });
+    }
+}
+```
+
+## 组件同步系统
+
+基于 `@sync` 装饰器的 ECS 组件状态同步。
+
+### 定义同步组件
+
+```typescript
+import { Component, ECSComponent, sync } from '@esengine/ecs-framework';
+
+@ECSComponent('Player')
+class PlayerComponent extends Component {
+    @sync("string") name: string = "";
+    @sync("uint16") score: number = 0;
+    @sync("float32") x: number = 0;
+    @sync("float32") y: number = 0;
+
+    // 不带 @sync 的字段不会同步
+    localData: any;
+}
+```
+
+### 服务端编码
+
+```typescript
+import { ComponentSyncSystem } from '@esengine/network';
+
+const syncSystem = new ComponentSyncSystem({}, true);

+description: "事务系统的核心概念：事务上下文、事务管理器、Saga 模式"
+---
+
+## 事务状态
+
+事务有以下几种状态：
+
+```typescript
+type TransactionState =
+    | 'pending'     // 等待执行
+    | 'executing'   // 执行中
+    | 'committed'   // 已提交
+    | 'rolledback'  // 已回滚
+    | 'failed'      // 失败
+```
+
+## TransactionContext
+
+事务上下文封装了事务的状态、操作和执行逻辑。
+
+### 创建事务
+
+```typescript
+import { TransactionManager } from '@esengine/transaction';
+
+const manager = new TransactionManager();
+
+// 方式 1：使用 begin() 手动管理
+const tx = manager.begin({ timeout: 5000 });
+tx.addOperation(op1);
+tx.addOperation(op2);
+const result = await tx.execute();
+
+// 方式 2：使用 run() 自动管理
+const result = await manager.run((tx) => {
+    tx.addOperation(op1);
+    tx.addOperation(op2);
+});
+```
+
+### 链式添加操作
+
+```typescript
+const result = await manager.run((tx) => {
+    tx.addOperation(new CurrencyOperation({ ... }))
+      .addOperation(new InventoryOperation({ ... }))
+      .addOperation(new InventoryOperation({ ... }));
+});
+```
+
+### 上下文数据
+
+操作之间可以通过上下文共享数据：
+
+```typescript
+class CustomOperation extends BaseOperation<MyData, MyResult> {
+    async execute(ctx: ITransactionContext): Promise<OperationResult<MyResult>> {
+        // 读取之前操作设置的数据
+        const previousResult = ctx.get<number>('previousValue');
+
+        // 设置数据供后续操作使用
+        ctx.set('myResult', { value: 123 });
+
+        return this.success({ ... });
+    }
+}
+```
+
+## TransactionManager
+
+事务管理器负责创建、执行和恢复事务。
+
+### 配置选项
+
+```typescript
+interface TransactionManagerConfig {
+    storage?: ITransactionStorage;    // 存储实例
+    defaultTimeout?: number;          // 默认超时（毫秒）
+    serverId?: string;                // 服务器 ID（分布式用）
+    autoRecover?: boolean;            // 自动恢复未完成事务
+}
+
+const manager = new TransactionManager({
+    storage: new RedisStorage({ client: redis }),
+    defaultTimeout: 10000,
+    serverId: 'server-1',
+    autoRecover: true,
+});
+```
+
+### 分布式锁
+
+```typescript
+// 获取锁
+const token = await manager.acquireLock('player:123:inventory', 10000);
+
+if (token) {
+    try {
+        // 执行操作
+        await doSomething();
+    } finally {
+        // 释放锁
+        await manager.releaseLock('player:123:inventory', token);
+    }
+}
+
+// 或使用 withLock 简化
+await manager.withLock('player:123:inventory', async () => {
+    await doSomething();
+}, 10000);
+```
+
+### 事务恢复
+
+服务器重启时恢复未完成的事务：
+
+```typescript
+const manager = new TransactionManager({
+    storage: new RedisStorage({ client: redis }),
+    serverId: 'server-1',
+});
+
+// 恢复未完成的事务
+const recoveredCount = await manager.recover();
+console.log(`Recovered ${recoveredCount} transactions`);
+```
+
+## Saga 模式
+
+事务系统采用 Saga 模式，每个操作必须实现 `execute` 和 `compensate` 方法：
+
+```typescript
+interface ITransactionOperation<TData, TResult> {
+    readonly name: string;
+    readonly data: TData;
+
+    // 验证前置条件
+    validate(ctx: ITransactionContext): Promise<boolean>;
+
+    // 正向执行
+    execute(ctx: ITransactionContext): Promise<OperationResult<TResult>>;
+
+    // 补偿操作（回滚）
+    compensate(ctx: ITransactionContext): Promise<void>;
+}
+```
+
+### 执行流程
+
+```

+            await this.saveItem(ctx, item);
+        }
+    }
+
+    private async getItem(ctx: ITransactionContext) {
+        // 从存储获取物品
+    }
+
+    private async saveItem(ctx: ITransactionContext, item: any) {
+        // 保存物品到存储
+    }
+}
+```
+
+## 事务结果

+
+## Saga 编排器
+
+`SagaOrchestrator` 用于编排跨服务器的分布式事务。
+
+### 基本用法
+
+```typescript
+import { SagaOrchestrator, RedisStorage } from '@esengine/transaction';
+
+const orchestrator = new SagaOrchestrator({
+    storage: new RedisStorage({ client: redis }),
+    timeout: 30000,
+    serverId: 'orchestrator-1',
+});
+
+const result = await orchestrator.execute([
+    {
+        name: 'deduct_currency',
+        serverId: 'game-server-1',
+        data: { playerId: 'player1', amount: 100 },
+        execute: async (data) => {
+            // 调用游戏服务器 API 扣除货币
+            const response = await gameServerApi.deductCurrency(data);
+            return { success: response.ok };
+        },
+        compensate: async (data) => {
+            // 调用游戏服务器 API 恢复货币
+            await gameServerApi.addCurrency(data);
+        },
+    },
+    {
+        name: 'add_item',
+        serverId: 'inventory-server-1',
+        data: { playerId: 'player1', itemId: 'sword' },
+        execute: async (data) => {
+            const response = await inventoryServerApi.addItem(data);
+            return { success: response.ok };
+        },
+        compensate: async (data) => {
+            await inventoryServerApi.removeItem(data);
+        },
+    },
+]);
+
+if (result.success) {
+    console.log('Saga completed successfully');
+} else {
+    console.log('Saga failed:', result.error);
+    console.log('Completed steps:', result.completedSteps);
+    console.log('Failed at:', result.failedStep);
+}
+```
+
+### 配置选项
+
+```typescript
+interface SagaOrchestratorConfig {
+    storage?: ITransactionStorage;  // 存储实例
+    timeout?: number;               // 超时时间（毫秒）
+    serverId?: string;              // 编排器服务器 ID
+}
+```
+
+### Saga 步骤
+
+```typescript
+interface SagaStep<T = unknown> {
+    name: string;                   // 步骤名称
+    serverId?: string;              // 目标服务器 ID
+    data: T;                        // 步骤数据
+    execute: (data: T) => Promise<OperationResult>;    // 执行函数
+    compensate: (data: T) => Promise<void>;            // 补偿函数
+}
+```
+
+### Saga 结果
+
+```typescript
+interface SagaResult {
+    success: boolean;       // 是否成功
+    sagaId: string;         // Saga ID
+    completedSteps: string[]; // 已完成的步骤
+    failedStep?: string;    // 失败的步骤

+}
+
+type SagaLogState =

+    | 'compensated'   // 已补偿
+    | 'failed'        // 失败
+
+interface SagaStepLog {
+    name: string;                   // 步骤名称
+    serverId?: string;              // 服务器 ID

+    startedAt?: number;             // 开始时间
+    completedAt?: number;           // 完成时间
+    error?: string;                 // 错误信息
+}
+
+type SagaStepState =
+    | 'pending'       // 等待执行

+    | 'compensating'  // 补偿中
+    | 'compensated'   // 已补偿
+    | 'failed'        // 失败

+
+### 查询 Saga 日志
+
+```typescript
+const log = await orchestrator.getSagaLog('saga_xxx');
+
+if (log) {
+    console.log('Saga state:', log.state);
+    for (const step of log.steps) {
+        console.log(`  ${step.name}: ${step.state}`);
+    }
+}
+```
+
+## 跨服务器事务示例
+
+### 场景：跨服购买
+
+玩家在游戏服务器购买物品，货币在账户服务器，物品在背包服务器。
+
+```typescript
+const orchestrator = new SagaOrchestrator({

+
+async function crossServerPurchase(

+): Promise<SagaResult> {
+    return orchestrator.execute([

+            serverId: 'inventory-server',
+            data: { playerId, itemId },
+            execute: async (data) => {

+                return { success: result.ok, error: result.error };
+            },
+            compensate: async (data) => {
+                await inventoryService.removeItem(data.playerId, data.itemId);
+            },
+        },
+
+        // 步骤 3：记录购买日志
+        {
+            name: 'log_purchase',
+            serverId: 'log-server',
+            data: { playerId, itemId, price, timestamp: Date.now() },
+            execute: async (data) => {
+                await logService.recordPurchase(data);
+                return { success: true };
+            },
+            compensate: async (data) => {
+                await logService.cancelPurchase(data);
+            },
+        },
+    ]);
+}
+```
+
+### 场景：跨服交易
+
+两个玩家在不同服务器上进行交易。
+
+```typescript
+async function crossServerTrade(
+    playerA: { id: string; server: string; items: string[] },
+    playerB: { id: string; server: string; items: string[] }
+): Promise<SagaResult> {
+    const steps: SagaStep[] = [];
+
+    // 移除 A 的物品
+    for (const itemId of playerA.items) {
+        steps.push({
+            name: `remove_${playerA.id}_${itemId}`,
+            serverId: playerA.server,
+            data: { playerId: playerA.id, itemId },
+            execute: async (data) => {
+                return await inventoryService.removeItem(data.playerId, data.itemId);
+            },
+            compensate: async (data) => {
+                await inventoryService.addItem(data.playerId, data.itemId);
+            },
+        });
+    }
+
+    // 添加物品到 B
+    for (const itemId of playerA.items) {
+        steps.push({
+            name: `add_${playerB.id}_${itemId}`,
+            serverId: playerB.server,
+            data: { playerId: playerB.id, itemId },
+            execute: async (data) => {
+                return await inventoryService.addItem(data.playerId, data.itemId);
+            },
+            compensate: async (data) => {
+                await inventoryService.removeItem(data.playerId, data.itemId);
+            },
+        });
+    }
+
+    // 类似地处理 B 的物品...
+
+    return orchestrator.execute(steps);
+}
+```
+
+## 恢复未完成的 Saga
+
+服务器重启后恢复未完成的 Saga：
+
+```typescript
+const orchestrator = new SagaOrchestrator({
+    storage: redisStorage,
+    serverId: 'my-orchestrator',
+});
+
+// 恢复未完成的 Saga（会执行补偿）
+const recoveredCount = await orchestrator.recover();
+console.log(`Recovered ${recoveredCount} sagas`);
+```
+
+## 最佳实践
+
+### 1. 幂等性
+
+确保所有操作都是幂等的：
+
+```typescript
+{
+    execute: async (data) => {
+        // 使用唯一 ID 确保幂等
+        const result = await service.process(data.requestId, data);
+        return { success: result.ok };
+    },
+    compensate: async (data) => {
+        // 补偿也要幂等
+        await service.rollback(data.requestId);
+    },
+}
+```
+
+### 2. 超时处理
+
+设置合适的超时时间：
+
+```typescript
+const orchestrator = new SagaOrchestrator({
+    timeout: 60000,  // 跨服务器操作需要更长超时
+});
+```
+
+### 3. 监控和告警
+
+记录 Saga 执行结果：
+
+```typescript
+const result = await orchestrator.execute(steps);
+
+if (!result.success) {
+    // 发送告警
+    alertService.send({
+        type: 'saga_failed',
+        sagaId: result.sagaId,
+        failedStep: result.failedStep,
+        error: result.error,
+    });
+
+    // 记录详细日志
+    const log = await orchestrator.getSagaLog(result.sagaId);
+    logger.error('Saga failed', { log });
+}
+```

+## 快速开始
+
+### 基础用法
+
+```typescript
+import {
+    TransactionManager,
+    MemoryStorage,
+    CurrencyOperation,
+    InventoryOperation,
+} from '@esengine/transaction';
+
+// 创建事务管理器
+const manager = new TransactionManager({
+    storage: new MemoryStorage(),
+    defaultTimeout: 10000,
+});
+
+// 执行事务
+const result = await manager.run((tx) => {
+    // 扣除金币
+    tx.addOperation(new CurrencyOperation({
+        type: 'deduct',
+        playerId: 'player1',
+        currency: 'gold',
+        amount: 100,
+    }));
+
+    // 添加物品
+    tx.addOperation(new InventoryOperation({
+        type: 'add',
+        playerId: 'player1',
+        itemId: 'sword_001',
+        quantity: 1,
+    }));
+});
+
+if (result.success) {
+    console.log('购买成功！');
+} else {
+    console.log('购买失败：', result.error);
+}
+```
+
+### 玩家交易
+
+```typescript
+import { TradeOperation } from '@esengine/transaction';
+
+const result = await manager.run((tx) => {
+    tx.addOperation(new TradeOperation({
+        tradeId: 'trade_001',
+        partyA: {
+            playerId: 'player1',
+            items: [{ itemId: 'sword', quantity: 1 }],
+        },
+        partyB: {
+            playerId: 'player2',
+            currencies: [{ currency: 'gold', amount: 1000 }],
+        },
+    }));
+}, { timeout: 30000 });
+```
+
+### 使用 Redis 存储
+
+```typescript
+import Redis from 'ioredis';
+import { TransactionManager, RedisStorage } from '@esengine/transaction';
+
+const redis = new Redis('redis://localhost:6379');
+const storage = new RedisStorage({ client: redis });
+
+const manager = new TransactionManager({ storage });
+```
+
+### 使用 MongoDB 存储
+
+```typescript
+import { MongoClient } from 'mongodb';
+import { TransactionManager, MongoStorage } from '@esengine/transaction';
+
+const client = new MongoClient('mongodb://localhost:27017');
+await client.connect();
+const db = client.db('game');
+
+const storage = new MongoStorage({ db });
+await storage.ensureIndexes();
+
+const manager = new TransactionManager({ storage });
+```
+
+## 与 Room 集成
+
+```typescript
+import { Room } from '@esengine/server';
+import { withTransactions, CurrencyOperation, RedisStorage } from '@esengine/transaction';
+
+class GameRoom extends withTransactions(Room, {
+    storage: new RedisStorage({ client: redisClient }),
+}) {
+    @onMessage('Buy')
+    async handleBuy(data: { itemId: string }, player: Player) {
+        const result = await this.runTransaction((tx) => {
+            tx.addOperation(new CurrencyOperation({
+                type: 'deduct',
+                playerId: player.id,
+                currency: 'gold',
+                amount: getItemPrice(data.itemId),
+            }));
+        });
+
+        if (result.success) {
+            player.send('buy_success', { itemId: data.itemId });
+        } else {
+            player.send('buy_failed', { error: result.error });
+        }
+    }
+}
+```

+## 服务令牌
+
+用于依赖注入：
+
+```typescript
+import {
+    TransactionManagerToken,
+    TransactionStorageToken,
+} from '@esengine/transaction';
+
+const manager = services.get(TransactionManagerToken);
+```
+
+## 最佳实践
+
+### 1. 操作粒度
+
+```typescript
+// ✅ 好：细粒度操作，便于回滚
+tx.addOperation(new CurrencyOperation({ type: 'deduct', ... }));
+tx.addOperation(new InventoryOperation({ type: 'add', ... }));
+
+// ❌ 差：粗粒度操作，难以部分回滚
+tx.addOperation(new ComplexPurchaseOperation({ ... }));
+```
+
+### 2. 超时设置
+
+```typescript
+// 简单操作：短超时
+await manager.run(tx => { ... }, { timeout: 5000 });
+
+// 复杂交易：长超时
+await manager.run(tx => { ... }, { timeout: 30000 });
+
+// 跨服务器：更长超时
+await manager.run(tx => { ... }, { timeout: 60000, distributed: true });
+```
+
+### 3. 错误处理
+
+```typescript
+const result = await manager.run((tx) => { ... });
+
+if (!result.success) {
+    // 记录日志
+    logger.error('Transaction failed', {
+        transactionId: result.transactionId,
+        error: result.error,
+        duration: result.duration,
+    });
+
+    // 通知用户
+    player.send('error', { message: getErrorMessage(result.error) });
+}
+```

+## CurrencyOperation
+
+处理货币的增加和扣除。
+
+### 扣除货币
+
+```typescript
+import { CurrencyOperation } from '@esengine/transaction';
+
+tx.addOperation(new CurrencyOperation({
+    type: 'deduct',
+    playerId: 'player1',
+    currency: 'gold',

+```
+
+### 操作数据
+
+```typescript
+interface CurrencyOperationData {
+    type: 'add' | 'deduct';   // 操作类型
+    playerId: string;          // 玩家 ID
+    currency: string;          // 货币类型
+    amount: number;            // 数量
+    reason?: string;           // 原因/来源
+}
+```
+
+### 操作结果
+
+```typescript
+interface CurrencyOperationResult {
+    beforeBalance: number;     // 操作前余额
+    afterBalance: number;      // 操作后余额
+}
+```
+
+### 自定义数据提供者
+
+```typescript

+    }
+}
+
+// 使用自定义提供者
+const op = new CurrencyOperation({ ... });
+op.setProvider(new MyCurrencyProvider());
+tx.addOperation(op);
+```
+
+## InventoryOperation
+
+处理物品的添加、移除和更新。
+
+### 添加物品
+
+```typescript
+import { InventoryOperation } from '@esengine/transaction';
+
+tx.addOperation(new InventoryOperation({
+    type: 'add',
+    playerId: 'player1',
+    itemId: 'sword_001',
+    quantity: 1,
+    properties: { enchant: 'fire' },
+}));
+```
+
+### 移除物品
+
+```typescript
+tx.addOperation(new InventoryOperation({
+    type: 'remove',
+    playerId: 'player1',
+    itemId: 'potion_hp',
+    quantity: 5,
+}));
+```
+
+### 更新物品
+
+```typescript
+tx.addOperation(new InventoryOperation({
+    type: 'update',
+    playerId: 'player1',
+    itemId: 'sword_001',
+    quantity: 1,  // 可选，不传则保持原数量
+    properties: { enchant: 'lightning', level: 5 },
+}));
+```
+
+### 操作数据
+
+```typescript
+interface InventoryOperationData {
+    type: 'add' | 'remove' | 'update';  // 操作类型
+    playerId: string;                    // 玩家 ID
+    itemId: string;                      // 物品 ID
+    quantity: number;                    // 数量
+    properties?: Record<string, unknown>; // 物品属性
+    reason?: string;                     // 原因/来源
+}
+```
+
+### 操作结果
+
+```typescript
+interface InventoryOperationResult {
+    beforeItem?: ItemData;   // 操作前物品
+    afterItem?: ItemData;    // 操作后物品
+}
+
+interface ItemData {
+    itemId: string;
+    quantity: number;
+    properties?: Record<string, unknown>;
+}
+```
+
+### 自定义数据提供者
+
+```typescript
+interface IInventoryProvider {
+    getItem(playerId: string, itemId: string): Promise<ItemData | null>;
+    setItem(playerId: string, itemId: string, item: ItemData | null): Promise<void>;
+    hasCapacity?(playerId: string, count: number): Promise<boolean>;
+}
+
+class MyInventoryProvider implements IInventoryProvider {
+    async getItem(playerId: string, itemId: string): Promise<ItemData | null> {
+        return await db.getItem(playerId, itemId);
+    }
+
+    async setItem(playerId: string, itemId: string, item: ItemData | null): Promise<void> {
+        if (item) {
+            await db.saveItem(playerId, itemId, item);
+        } else {
+            await db.deleteItem(playerId, itemId);
+        }
+    }
+
+    async hasCapacity(playerId: string, count: number): Promise<boolean> {
+        const current = await db.getItemCount(playerId);
+        const max = await db.getMaxCapacity(playerId);
+        return current + count <= max;
+    }
+}
+```
+
+## TradeOperation
+
+处理玩家之间的物品和货币交换。
+
+### 基本用法
+
+```typescript
+import { TradeOperation } from '@esengine/transaction';
+
+tx.addOperation(new TradeOperation({
+    tradeId: 'trade_001',
+    partyA: {
+        playerId: 'player1',
+        items: [{ itemId: 'sword', quantity: 1 }],
+        currencies: [{ currency: 'diamond', amount: 10 }],
+    },
+    partyB: {
+        playerId: 'player2',
+        currencies: [{ currency: 'gold', amount: 1000 }],
+    },
+    reason: 'player_trade',
+}));
+```
+
+### 操作数据
+
+```typescript
+interface TradeOperationData {
+    tradeId: string;      // 交易 ID
+    partyA: TradeParty;   // 交易发起方
+    partyB: TradeParty;   // 交易接收方
+    reason?: string;      // 原因/备注
+}
+
+interface TradeParty {
+    playerId: string;              // 玩家 ID
+    items?: TradeItem[];           // 给出的物品
+    currencies?: TradeCurrency[];  // 给出的货币
+}
+
+interface TradeItem {
+    itemId: string;
+    quantity: number;
+}
+
+interface TradeCurrency {
+    currency: string;
+    amount: number;
+}
+```
+
+### 执行流程
+
+TradeOperation 内部会生成以下子操作序列：
+
+```
+1. 移除 partyA 的物品
+2. 添加 partyB 的物品（来自 partyA）
+3. 扣除 partyA 的货币
+4. 增加 partyB 的货币（来自 partyA）
+5. 移除 partyB 的物品
+6. 添加 partyA 的物品（来自 partyB）
+7. 扣除 partyB 的货币
+8. 增加 partyA 的货币（来自 partyB）
+```
+
+任何一步失败都会回滚之前的所有操作。
+
+### 使用自定义提供者
+
+```typescript
+const op = new TradeOperation({ ... });
+op.setProvider({
+    currencyProvider: new MyCurrencyProvider(),
+    inventoryProvider: new MyInventoryProvider(),
+});
+tx.addOperation(op);
+```
+
+## 创建工厂函数
+
+每个操作类都提供工厂函数：
+
+```typescript
+import {
+    createCurrencyOperation,
+    createInventoryOperation,
+    createTradeOperation,
+} from '@esengine/transaction';
+
+tx.addOperation(createCurrencyOperation({
+    type: 'deduct',
+    playerId: 'player1',
+    currency: 'gold',
+    amount: 100,
+}));
+
+tx.addOperation(createInventoryOperation({
+    type: 'add',
+    playerId: 'player1',
+    itemId: 'sword',
+    quantity: 1,
+}));
+```

+---
+title: "存储层"
+description: "事务存储接口和实现：MemoryStorage、RedisStorage、MongoStorage"
+---
+
+## 存储接口
+
+所有存储实现都需要实现 `ITransactionStorage` 接口：
+
+```typescript
+interface ITransactionStorage {
+    // 生命周期
+    close?(): Promise<void>;
+
+    // 分布式锁
+    acquireLock(key: string, ttl: number): Promise<string | null>;
+    releaseLock(key: string, token: string): Promise<boolean>;
+
+    // 事务日志
+    saveTransaction(tx: TransactionLog): Promise<void>;
+    getTransaction(id: string): Promise<TransactionLog | null>;
+    updateTransactionState(id: string, state: TransactionState): Promise<void>;
+    updateOperationState(txId: string, opIndex: number, state: string, error?: string): Promise<void>;
+    getPendingTransactions(serverId?: string): Promise<TransactionLog[]>;
+    deleteTransaction(id: string): Promise<void>;
+
+    // 数据操作
+    get<T>(key: string): Promise<T | null>;
+    set<T>(key: string, value: T, ttl?: number): Promise<void>;
+    delete(key: string): Promise<boolean>;
+}
+```
+
+## MemoryStorage
+
+内存存储，适用于开发和测试环境。
+
+```typescript
+import { MemoryStorage } from '@esengine/transaction';
+
+const storage = new MemoryStorage({
+    maxTransactions: 1000,  // 最大事务日志数量
+});
+
+const manager = new TransactionManager({ storage });
+```
+
+### 特点
+
+- ✅ 无需外部依赖
+- ✅ 快速，适合开发调试
+- ❌ 数据仅保存在内存中
+- ❌ 不支持真正的分布式锁
+- ❌ 服务重启后数据丢失
+
+### 测试辅助
+
+```typescript
+// 清空所有数据
+storage.clear();
+
+// 获取事务数量
+console.log(storage.transactionCount);
+```
+
+## RedisStorage
+
+Redis 存储，适用于生产环境的分布式系统。使用工厂模式实现惰性连接。
+
+```typescript
+import Redis from 'ioredis';
+import { RedisStorage } from '@esengine/transaction';
+
+// 工厂模式：惰性连接，首次操作时才创建连接
+const storage = new RedisStorage({
+    factory: () => new Redis('redis://localhost:6379'),
+    prefix: 'tx:',              // 键前缀
+    transactionTTL: 86400,      // 事务日志过期时间（秒）
+});
+
+const manager = new TransactionManager({ storage });
+
+// 使用后关闭连接
+await storage.close();
+
+// 或使用 await using 自动关闭 (TypeScript 5.2+)
+await using storage = new RedisStorage({
+    factory: () => new Redis('redis://localhost:6379')
+});
+// 作用域结束时自动关闭
+```
+
+### 特点
+
+- ✅ 高性能分布式锁
+- ✅ 快速读写
+- ✅ 支持 TTL 自动过期
+- ✅ 适合高并发场景
+- ❌ 需要 Redis 服务器
+
+### 分布式锁实现
+
+使用 Redis `SET NX EX` 实现分布式锁：
+
+```typescript
+// 获取锁（原子操作）
+SET tx:lock:player:123 <token> NX EX 10
+
+// 释放锁（Lua 脚本保证原子性）
+if redis.call("get", KEYS[1]) == ARGV[1] then
+    return redis.call("del", KEYS[1])
+else
+    return 0
+end
+```
+
+### 键结构
+
+```
+tx:lock:{key}           - 分布式锁
+tx:tx:{id}              - 事务日志
+tx:server:{id}:txs      - 服务器事务索引
+tx:data:{key}           - 业务数据
+```
+
+## MongoStorage
+
+MongoDB 存储，适用于需要持久化和复杂查询的场景。使用 `@esengine/database-drivers` 的共享连接。
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers';
+import { createMongoStorage, TransactionManager } from '@esengine/transaction';
+
+// 创建共享连接
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game'
+});
+await mongo.connect();
+
+// 使用共享连接创建存储
+const storage = createMongoStorage(mongo, {
+    transactionCollection: 'transactions',  // 事务日志集合（可选）
+    dataCollection: 'transaction_data',     // 业务数据集合（可选）
+    lockCollection: 'transaction_locks',    // 锁集合（可选）
+});
+
+// 创建索引（首次运行时执行）
+await storage.ensureIndexes();
+
+const manager = new TransactionManager({ storage });
+
+// 关闭存储（不会关闭共享连接）
+await storage.close();
+
+// 共享连接可继续用于其他模块
+const userRepo = new UserRepository(mongo);  // @esengine/database
+
+// 最后关闭共享连接
+await mongo.disconnect();
+```
+
+### 特点
+
+- ✅ 持久化存储
+- ✅ 支持复杂查询
+- ✅ 事务日志可追溯
+- ✅ 适合需要审计的场景
+- ❌ 相比 Redis 性能略低
+- ❌ 需要 MongoDB 服务器
+
+### 索引结构
+
+```javascript
+// transactions 集合
+{ state: 1 }
+{ 'metadata.serverId': 1 }
+{ createdAt: 1 }
+
+// transaction_locks 集合
+{ expireAt: 1 }  // TTL 索引
+
+// transaction_data 集合
+{ expireAt: 1 }  // TTL 索引
+```
+
+### 分布式锁实现
+
+使用 MongoDB 唯一索引实现分布式锁：
+
+```typescript
+// 获取锁
+db.transaction_locks.insertOne({
+    _id: 'player:123',
+    token: '<token>',
+    expireAt: new Date(Date.now() + 10000)
+});
+
+// 如果键已存在，检查是否过期
+db.transaction_locks.updateOne(
+    { _id: 'player:123', expireAt: { $lt: new Date() } },
+    { $set: { token: '<token>', expireAt: new Date(Date.now() + 10000) } }
+);
+```
+
+## 存储选择指南
+
+| 场景 | 推荐存储 | 理由 |
+|------|----------|------|
+| 开发/测试 | MemoryStorage | 无依赖，快速启动 |
+| 单机生产 | RedisStorage | 高性能，简单 |
+| 分布式系统 | RedisStorage | 真正的分布式锁 |
+| 需要审计 | MongoStorage | 持久化日志 |
+| 混合需求 | Redis + Mongo | Redis 做锁，Mongo 做日志 |
+
+## 自定义存储
+
+实现 `ITransactionStorage` 接口创建自定义存储：
+
+```typescript
+import { ITransactionStorage, TransactionLog, TransactionState } from '@esengine/transaction';
+
+class MyCustomStorage implements ITransactionStorage {
+    async acquireLock(key: string, ttl: number): Promise<string | null> {
+        // 实现分布式锁获取逻辑
+    }
+
+    async releaseLock(key: string, token: string): Promise<boolean> {
+        // 实现分布式锁释放逻辑
+    }
+
+    async saveTransaction(tx: TransactionLog): Promise<void> {
+        // 保存事务日志
+    }
+
+    // ... 实现其他方法
+}
+```

+# ESEngine Editor
+
+A cross-platform desktop visual editor built with Tauri 2.x + React 18.
+
+## Prerequisites
+
+Before running the editor, ensure you have the following installed:
+
+- **Node.js** >= 18.x
+- **pnpm** >= 10.x
+- **Rust** >= 1.70 (for Tauri and WASM builds)
+- **wasm-pack** (for building Rapier2D physics engine)
+- **Platform-specific dependencies**:
+  - **Windows**: Microsoft Visual Studio C++ Build Tools
+  - **macOS**: Xcode Command Line Tools (`xcode-select --install`)
+  - **Linux**: See [Tauri prerequisites](https://tauri.app/v1/guides/getting-started/prerequisites)
+
+### Installing wasm-pack
+
+```bash
+# Using cargo
+cargo install wasm-pack
+
+# Or using the official installer script (Linux/macOS)
+curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
+```
+
+## Quick Start
+
+### 1. Clone and Install
+
+```bash
+git clone https://github.com/esengine/esengine.git
+cd esengine
+pnpm install
+```
+
+### 2. Build Rapier2D WASM
+
+The editor depends on Rapier2D physics engine WASM artifacts. First-time setup only requires one command:
+
+```bash
+pnpm build:rapier2d
+```
+
+This command automatically:
+1. Prepares the Rust project
+2. Builds WASM
+3. Copies artifacts to `packages/physics/rapier2d/pkg`
+4. Generates TypeScript source code
+
+> **Note**: Requires Rust and wasm-pack to be installed.
+
+### 3. Build Editor
+
+From the project root:
+
+```bash
+pnpm build:editor
+```
+
+### 4. Run Editor
+
+```bash
+cd packages/editor/editor-app
+pnpm tauri:dev
+```
+
+## Available Scripts
+
+| Script | Description |
+|--------|-------------|
+| `pnpm build:rapier2d` | Build Rapier2D WASM (required for first-time setup) |
+| `pnpm build:editor` | Build editor and all dependencies |
+| `pnpm tauri:dev` | Run editor in development mode with hot-reload |
+| `pnpm tauri:build` | Build production application |
+| `pnpm build:sdk` | Build editor-runtime SDK |
+
+## Project Structure

+```
+
+## Troubleshooting
+
+### Rapier2D WASM Build Failed
+
+**Error**: `Could not resolve "../pkg/rapier_wasm2d"`
+
+**Cause**: Missing Rapier2D WASM artifacts.
+
+**Solution**:
+1. Ensure `wasm-pack` is installed: `cargo install wasm-pack`
+2. Run `pnpm build:rapier2d`
+3. Verify `packages/physics/rapier2d/pkg/` directory exists and contains `rapier_wasm2d_bg.wasm` file
+
+### Build Errors
+
+```bash
+pnpm clean
+pnpm install
+pnpm build:editor
+```
+
+### Rust/Tauri Errors
+
+```bash
+rustup update
+```
+
+### Windows Users Building WASM
+
+The `pnpm build:rapier2d` script works directly on Windows. If you encounter issues:
+1. Use Git Bash or WSL
+2. Or download pre-built WASM artifacts from [Releases](https://github.com/esengine/esengine/releases)

 # @esengine/behavior-tree
 
+## 4.2.0
+
+### Minor Changes
+
+- [#408](https://github.com/esengine/esengine/pull/408) [`b9ea8d1`](https://github.com/esengine/esengine/commit/b9ea8d14cf38e1480f638c229f9ee150b65f0c60) Thanks [@esengine](https://github.com/esengine)! - feat: add action() and condition() methods to BehaviorTreeBuilder
+
+    Added new methods to support custom executor types directly in the builder:
+    - `action(implementationType, name?, config?)` - Use custom action executors registered via `@NodeExecutorMetadata`
+    - `condition(implementationType, name?, config?)` - Use custom condition executors
+
+    This provides a cleaner API for using custom node executors compared to the existing `executeAction()` which only supports blackboard functions.
+
+    Example:
+
+    ```typescript
+    // Define custom executor
+    @NodeExecutorMetadata({
+        implementationType: 'AttackAction',
+        nodeType: NodeType.Action,
+        displayName: 'Attack',
+        category: 'Combat'
+    })
+    class AttackAction implements INodeExecutor {
+        execute(context: NodeExecutionContext): TaskStatus {
+            return TaskStatus.Success;
+        }
+    }
+
+    // Use in builder
+    const tree = BehaviorTreeBuilder.create('AI')
+        .selector('Root')
+        .action('AttackAction', 'Attack', { damage: 50 })
+        .end()
+        .build();
+    ```

+- [#406](https://github.com/esengine/esengine/pull/406) [`0de4527`](https://github.com/esengine/esengine/commit/0de45279e612c04ae9be7fbd65ce496e4797a43c) Thanks [@esengine](https://github.com/esengine)! - fix(behavior-tree): export NodeExecutorMetadata as value instead of type
+
+    Fixed the export of `NodeExecutorMetadata` decorator in `execution/index.ts`.
+    Previously it was exported as `export type { NodeExecutorMetadata }` which only
+    exported the type signature, not the actual function. This caused runtime errors
+    in Cocos Creator: "TypeError: (intermediate value) is not a function".
+
+    Changed to `export { NodeExecutorMetadata }` to properly export the decorator function.

+## 4.1.0
+
+### Minor Changes
+
+- [#400](https://github.com/esengine/esengine/pull/400) [`d2af9ca`](https://github.com/esengine/esengine/commit/d2af9caae9d5620c5f690272ab80dc246e9b7e10) Thanks [@esengine](https://github.com/esengine)! - feat(behavior-tree): add pure BehaviorTreePlugin class for Cocos/Laya integration
+    - Added `BehaviorTreePlugin` class that only depends on `@esengine/ecs-framework`
+    - Implements `IPlugin` interface with `install()`, `uninstall()`, and `setupScene()` methods
+    - Removed `esengine/` subdirectory that incorrectly depended on `@esengine/engine-core`
+    - Updated package documentation with correct usage examples
+
+    Usage:
+
+    ```typescript
+    import { Core, Scene } from '@esengine/ecs-framework';
+    import { BehaviorTreePlugin, BehaviorTreeBuilder, BehaviorTreeStarter } from '@esengine/behavior-tree';
+
+    Core.create();
+    const plugin = new BehaviorTreePlugin();
+    await Core.installPlugin(plugin);
+
+    const scene = new Scene();
+    plugin.setupScene(scene);
+    Core.setScene(scene);
+    ```

+    - 新增 `RuntimeConfig` 模块，作为运行时环境配置的独立存储
+    - `Core.runtimeEnvironment` 和 `Scene.runtimeEnvironment` 现在都从 `RuntimeConfig` 读取
+    - 移除 `Scene.ts` 中的 `require()` 调用，解决 Node.js ESM 环境下的兼容性问题
+
+    此修复解决了在 Node.js ESM 环境（如游戏服务端）中使用 `scene.isServer` 时报错 `ReferenceError: require is not defined` 的问题。

+
+    新增功能：
+    - `Core` 新增静态属性 `runtimeEnvironment`，支持 `'server' | 'client' | 'standalone'`
+    - `Core` 新增 `isServer` / `isClient` 静态只读属性
+    - `ICoreConfig` 新增 `runtimeEnvironment` 配置项
+    - `Scene` 新增 `isServer` / `isClient` 只读属性（默认从 Core 继承，可通过 config 覆盖）
+    - 新增 `@ServerOnly()` / `@ClientOnly()` / `@NotServer()` / `@NotClient()` 方法装饰器
+
+    用于网络游戏中区分服务端权威逻辑和客户端逻辑：
+
+    ```typescript
+    // 方式1: 全局设置（推荐）
+    Core.create({ runtimeEnvironment: 'server' });
+    // 或直接设置静态属性
+    Core.runtimeEnvironment = 'server';
+
+    // 所有场景自动继承
+    const scene = new Scene();
+    console.log(scene.isServer); // true
+
+    // 方式2: 单个场景覆盖（可选）
+    const clientScene = new Scene({ runtimeEnvironment: 'client' });
+
+    // 在系统中检查环境
+    class CollectibleSpawnSystem extends EntitySystem {
+        private checkCollections(): void {
+            if (!this.scene.isServer) return; // 客户端跳过
+            // ... 服务端权威逻辑

+
+    修复 `ECSEventType.COMPONENT_ADDED` 事件缺少 `entity` 字段的问题，导致 ECSRoom 的 `@NetworkEntity` 自动广播功能报错。
+
+## 2.6.0
+
+### Minor Changes
+
+- feat(ecs): 添加 @NetworkEntity 装饰器，支持自动广播实体生成/销毁
+
+    ### 新功能
+
+    **@NetworkEntity 装饰器**
+    - 标记组件为网络实体，自动广播 spawn/despawn 消息
+    - 支持 `autoSpawn` 和 `autoDespawn` 配置选项
+    - 通过事件系统（`ECSEventType.COMPONENT_ADDED` / `ECSEventType.ENTITY_DESTROYED`）实现
+
+    **ECSRoom 增强**
+    - 新增 `enableAutoNetworkEntity` 配置选项（默认启用）
+    - 自动监听组件添加和实体销毁事件
+    - 简化 GameRoom 实现，无需手动回调
+
+    ### 改进
+
+    **Entity 事件**
+    - `Entity.destroy()` 现在发出 `entity:destroyed` 事件
+    - `Entity.active` 变化时发出 `entity:enabled` / `entity:disabled` 事件
+    - 使用 `ECSEventType` 常量替代硬编码字符串
+
+    ### 使用示例
+
+    ```typescript
+    import { Component, ECSComponent, sync, NetworkEntity } from '@esengine/ecs-framework';
+
+    @ECSComponent('Enemy')
+    @NetworkEntity('Enemy')
+    class EnemyComponent extends Component {
+        @sync('float32') x: number = 0;
+        @sync('float32') y: number = 0;
+    }
+
+    // 服务端
+    const entity = scene.createEntity('Enemy');
+    entity.addComponent(new EnemyComponent()); // 自动广播 spawn
+    entity.destroy(); // 自动广播 despawn
+    ```

+
+    **问题 | Problem:**
+    1. `Decoder.ts` 有自己独立的 `componentRegistry` Map，与 `GlobalComponentRegistry` 完全分离。这导致通过 `@ECSComponent` 装饰器注册的组件在网络反序列化时找不到，产生 "Unknown component type" 错误。
+    2. `@sync` 装饰器使用 `constructor.name` 作为 `typeId`，而不是 `@ECSComponent` 装饰器指定的名称，导致编码和解码使用不同的类型 ID。
+    3. `Decoder.ts` had its own local `componentRegistry` Map that was completely separate from `GlobalComponentRegistry`. This caused components registered via `@ECSComponent` decorator to not be found during network deserialization, resulting in "Unknown component type" errors.
+    4. `@sync` decorator used `constructor.name` as `typeId` instead of the name specified by `@ECSComponent` decorator, causing encoding and decoding to use different type IDs.
+
+    **修改 | Changes:**
+    - 从 Decoder.ts 中移除本地 `componentRegistry`
+    - 更新 `decodeEntity` 和 `decodeSpawn` 使用 `GlobalComponentRegistry.getComponentType()`
+    - 移除已废弃的 `registerSyncComponent` 和 `autoRegisterSyncComponent` 函数
+    - 更新 `@sync` 装饰器使用 `getComponentTypeName()` 获取组件类型名称
+    - 更新 `@ECSComponent` 装饰器同步更新 `SYNC_METADATA.typeId`
+    - Removed local `componentRegistry` from Decoder.ts
+    - Updated `decodeEntity` and `decodeSpawn` to use `GlobalComponentRegistry.getComponentType()`
+    - Removed deprecated `registerSyncComponent` and `autoRegisterSyncComponent` functions
+    - Updated `@sync` decorator to use `getComponentTypeName()` for component type name
+    - Updated `@ECSComponent` decorator to sync update `SYNC_METADATA.typeId`
+
+    现在使用 `@ECSComponent` 装饰器的组件会自动可用于网络同步解码，无需手动注册。
+
+    Now `@ECSComponent` decorated components are automatically available for network sync decoding without any manual registration.

+
+    ## @esengine/ecs-framework
+
+    新增 `@sync` 装饰器和二进制编解码器，支持基于 Component 的网络状态同步：
+
+    ```typescript
+    import { Component, ECSComponent, sync } from '@esengine/ecs-framework';
+
+    @ECSComponent('Player')
+    class PlayerComponent extends Component {
+        @sync('string') name: string = '';
+        @sync('uint16') score: number = 0;
+        @sync('float32') x: number = 0;
+        @sync('float32') y: number = 0;
+    }
+    ```
+
+    ### 新增导出
+    - `sync` - 标记需要同步的字段装饰器
+    - `SyncType` - 支持的同步类型
+    - `SyncOperation` - 同步操作类型（FULL/DELTA/SPAWN/DESPAWN）
+    - `encodeSnapshot` / `decodeSnapshot` - 批量编解码
+    - `encodeSpawn` / `decodeSpawn` - 实体生成编解码
+    - `encodeDespawn` / `processDespawn` - 实体销毁编解码
+    - `ChangeTracker` - 字段级变更追踪
+    - `initChangeTracker` / `clearChanges` / `hasChanges` - 变更追踪工具函数
+
+    ### 内部方法标记
+
+    将以下方法标记为 `@internal`，用户应通过 `Core.update()` 驱动更新：
+    - `Scene.update()`
+    - `SceneManager.update()`
+    - `WorldManager.updateAll()`
+
+    ## @esengine/network
+
+    新增 `ComponentSyncSystem`，基于 `@sync` 装饰器自动同步组件状态：
+
+    ```typescript
+    import { ComponentSyncSystem } from '@esengine/network';
+
+    // 服务端：编码状态
+    const data = syncSystem.encodeAllEntities(false);
+
+    // 客户端：解码状态
+    syncSystem.applySnapshot(data);
+    ```
+
+    ### 修复
+    - 将 `@esengine/ecs-framework` 从 devDependencies 移到 peerDependencies
+
+    ## @esengine/server
+
+    新增 `ECSRoom`，带有 ECS World 支持的房间基类：
+
+    ```typescript
+    import { ECSRoom } from '@esengine/server/ecs';
+
+    // 服务端启动
+    Core.create();
+    setInterval(() => Core.update(1 / 60), 16);
+
+    // 定义房间
+    class GameRoom extends ECSRoom {
+        onCreate() {
+            this.addSystem(new PhysicsSystem());
+        }
+
+        onJoin(player: Player) {
+            const entity = this.createPlayerEntity(player.id);
+            entity.addComponent(new PlayerComponent());
+        }
+    }
+    ```
+
+    ### 设计
+    - 每个 `ECSRoom` 在 `Core.worldManager` 中创建独立的 World
+    - `Core.update()` 统一更新 Time 和所有 World
+    - `onTick()` 只处理状态同步逻辑
+

+# @esengine/database-drivers
+
+## 1.1.0
+
+### Minor Changes
+
+- [#410](https://github.com/esengine/esengine/pull/410) [`71022ab`](https://github.com/esengine/esengine/commit/71022abc99ad4a1b349f19f4ccf1e0a2a0923dfa) Thanks [@esengine](https://github.com/esengine)! - feat: add database layer architecture
+
+    Added new database packages with layered architecture:
+
+    **@esengine/database-drivers (Layer 1)**
+    - MongoDB connection with pool management, auto-reconnect, events
+    - Redis connection with auto-reconnect, key prefix
+    - Type-safe `IMongoCollection<T>` interface decoupled from mongodb types
+    - Service tokens for dependency injection (`MongoConnectionToken`, `RedisConnectionToken`)
+
+    **@esengine/database (Layer 2)**
+    - Generic `Repository<T>` with CRUD, pagination, soft delete
+    - `UserRepository` with registration, authentication, role management
+    - Password hashing utilities using scrypt
+    - Query operators: `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$in`, `$nin`, `$like`, `$regex`
+
+    **@esengine/transaction**
+    - Refactored `MongoStorage` to use shared connection from `@esengine/database-drivers`
+    - Removed factory pattern in favor of shared connection (breaking change)
+    - Simplified API: `createMongoStorage(connection, options?)`
+
+    Example usage:
+
+    ```typescript
+    import { createMongoConnection } from '@esengine/database-drivers';
+    import { UserRepository } from '@esengine/database';
+    import { createMongoStorage, TransactionManager } from '@esengine/transaction';
+
+    // Create shared connection
+    const mongo = createMongoConnection({
+        uri: 'mongodb://localhost:27017',
+        database: 'game'
+    });
+    await mongo.connect();
+
+    // Use for database operations
+    const userRepo = new UserRepository(mongo);
+    await userRepo.register({ username: 'john', password: '123456' });
+
+    // Use for transactions (same connection)
+    const storage = createMongoStorage(mongo);
+    const txManager = new TransactionManager({ storage });
+    ```
