+title: "Area of Interest (AOI)"
+description: "View range based network entity filtering"
+---
+
+AOI (Area of Interest) is a key technique in large-scale multiplayer games for optimizing network bandwidth. By only synchronizing entities within a player's view range, network traffic can be significantly reduced.
+
+## NetworkAOISystem
+
+`NetworkAOISystem` provides grid-based area of interest management.
+
+### Enable AOI
+
+```typescript
+import { NetworkPlugin } from '@esengine/network';
+
+const networkPlugin = new NetworkPlugin({
+    enableAOI: true,
+    aoiConfig: {
+        cellSize: 100,           // Grid cell size
+        defaultViewRange: 500,   // Default view range
+        enabled: true,
+    }
+});
+
+await Core.installPlugin(networkPlugin);
+```
+
+### Adding Observers
+
+Each player that needs to receive sync data must be added as an observer:
+
+```typescript
+// Add observer when player joins
+networkPlugin.registerPrefab('player', (scene, spawn) => {
+    const entity = scene.createEntity(`player_${spawn.netId}`);
+
+    // ... setup components
+
+    // Add player as AOI observer
+    networkPlugin.addAOIObserver(
+        spawn.netId,     // Network ID
+        spawn.pos.x,     // Initial X position
+        spawn.pos.y,     // Initial Y position
+        600              // View range (optional)
+    );
+
+    return entity;
+});
+
+// Remove observer when player leaves
+networkPlugin.removeAOIObserver(playerNetId);
+```
+
+### Updating Observer Position
+
+When a player moves, update their AOI position:
+
+```typescript
+// Update in game loop or sync callback
+networkPlugin.updateAOIObserverPosition(playerNetId, newX, newY);
+```
+
+## AOI Configuration
+
+| Property | Type | Default | Description |
+|----------|------|---------|-------------|
+| `cellSize` | `number` | 100 | Grid cell size |
+| `defaultViewRange` | `number` | 500 | Default view range |
+| `enabled` | `boolean` | true | Whether AOI is enabled |
+
+### Grid Size Recommendations
+
+Grid size should be set based on game view range:
+
+```typescript
+// Recommendation: cellSize = defaultViewRange / 3 to / 5
+aoiConfig: {
+    cellSize: 100,
+    defaultViewRange: 500,  // Grid is about 1/5 of view range
+}
+```
+
+## Query Interface
+
+### Get Visible Entities
+
+```typescript
+// Get all entities visible to player
+const visibleEntities = networkPlugin.getVisibleEntities(playerNetId);
+console.log('Visible entities:', visibleEntities);
+```
+
+### Check Visibility
+
+```typescript
+// Check if player can see an entity
+if (networkPlugin.canSee(playerNetId, targetEntityNetId)) {
+    // Target is in view
+}
+```
+
+## Event Listening
+
+The AOI system triggers events when entities enter/exit view:
+
+```typescript
+const aoiSystem = networkPlugin.aoiSystem;
+
+if (aoiSystem) {
+    aoiSystem.addListener((event) => {
+        if (event.type === 'enter') {
+            console.log(`Entity ${event.targetNetId} entered view of ${event.observerNetId}`);
+            // Can send entity's initial state here
+        } else if (event.type === 'exit') {
+            console.log(`Entity ${event.targetNetId} left view of ${event.observerNetId}`);
+            // Can cleanup resources here
+        }
+    });
+}
+```
+
+## Server-Side Filtering
+
+AOI is most commonly used server-side to filter sync data for each client:
+
+```typescript
+// Server-side example
+import { NetworkAOISystem, createNetworkAOISystem } from '@esengine/network';
+
+class GameServer {
+    private aoiSystem = createNetworkAOISystem({
+        cellSize: 100,
+        defaultViewRange: 500,
+    });
+
+    // Player joins
+    onPlayerJoin(playerId: number, x: number, y: number) {
+        this.aoiSystem.addObserver(playerId, x, y);
+    }
+
+    // Player moves
+    onPlayerMove(playerId: number, x: number, y: number) {
+        this.aoiSystem.updateObserverPosition(playerId, x, y);
+    }
+
+    // Send sync data
+    broadcastSync(allEntities: EntitySyncState[]) {
+        for (const playerId of this.players) {
+            // Filter using AOI
+            const filteredEntities = this.aoiSystem.filterSyncData(
+                playerId,
+                allEntities
+            );
+
+            // Send only visible entities
+            this.sendToPlayer(playerId, { entities: filteredEntities });
+        }
+    }
+}
+```
+
+## How It Works

+```
+
+### Grid Optimization
+
+AOI uses spatial grid to accelerate queries:
+
+1. **Add Entity**: Calculate grid cell based on position
+2. **View Detection**: Only check cells covered by view range
+3. **Move Update**: Update cell assignment when crossing cells
+4. **Event Trigger**: Detect enter/exit view
+
+## Dynamic View Range
+
+Different player types can have different view ranges:
+
+```typescript
+// Regular player
+networkPlugin.addAOIObserver(playerId, x, y, 500);
+
+// VIP player (larger view)
+networkPlugin.addAOIObserver(vipPlayerId, x, y, 800);
+
+// Adjust view range at runtime
+const aoiSystem = networkPlugin.aoiSystem;
+if (aoiSystem) {
+    aoiSystem.updateObserverViewRange(playerId, 600);
+}
+```
+
+## Best Practices
+
+### 1. Server-Side Usage
+
+AOI filtering should be done server-side; clients should not trust their own AOI judgment:
+
+```typescript
+// Filter on server before sending
+const filtered = aoiSystem.filterSyncData(playerId, entities);
+sendToClient(playerId, filtered);
+```
+
+### 2. Edge Handling
+
+Add buffer zone at view edge to prevent flickering:
+
+```typescript
+// Add immediately when entering view
+// Remove with delay when exiting (keep for 1-2 extra seconds)
+aoiSystem.addListener((event) => {
+    if (event.type === 'exit') {
+        setTimeout(() => {
+            // Re-check if really exited
+            if (!aoiSystem.canSee(event.observerNetId, event.targetNetId)) {
+                removeFromClient(event.observerNetId, event.targetNetId);
+            }
+        }, 1000);
+    }
+});
+```
+
+### 3. Large Entities
+
+Large entities (like bosses) may need special handling:
+
+```typescript
+// Boss is always visible to everyone
+function filterWithBoss(playerId: number, entities: EntitySyncState[]) {
+    const filtered = aoiSystem.filterSyncData(playerId, entities);
+
+    // Add boss entity
+    const bossState = entities.find(e => e.netId === bossNetId);
+    if (bossState && !filtered.includes(bossState)) {
+        filtered.push(bossState);
+    }
+
+    return filtered;
+}
+```
+
+### 4. Performance Considerations
+
+```typescript
+// Large-scale game recommended config
+aoiConfig: {
+    cellSize: 200,           // Larger grid reduces cell count
+    defaultViewRange: 800,   // Set based on actual view
+}
+```
+
+## Debugging
+
+```typescript
+const aoiSystem = networkPlugin.aoiSystem;
+
+if (aoiSystem) {
+    console.log('AOI enabled:', aoiSystem.enabled);
+    console.log('Observer count:', aoiSystem.observerCount);
+
+    // Get visible entities for specific player
+    const visible = aoiSystem.getVisibleEntities(playerId);
+    console.log('Visible entities:', visible.length);
+}
+```

+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)
+```
+
+### 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: "State Delta Compression"
+description: "Reduce network bandwidth with incremental sync"
+---
+
+State delta compression reduces network bandwidth by only sending fields that have changed. For frequently synchronized game state, this can significantly reduce data transmission.
+
+## StateDeltaCompressor
+
+The `StateDeltaCompressor` class is used to compress and decompress state deltas.
+
+### Basic Usage
+
+```typescript
+import { createStateDeltaCompressor, type SyncData } from '@esengine/network';
+
+// Create compressor
+const compressor = createStateDeltaCompressor({
+    positionThreshold: 0.01,      // Position change threshold
+    rotationThreshold: 0.001,     // Rotation change threshold (radians)
+    velocityThreshold: 0.1,       // Velocity change threshold
+    fullSnapshotInterval: 60,     // Full snapshot interval (frames)
+});
+
+// Compress sync data
+const syncData: SyncData = {
+    frame: 100,
+    timestamp: Date.now(),
+    entities: [
+        { netId: 1, pos: { x: 100, y: 200 }, rot: 0 },
+        { netId: 2, pos: { x: 300, y: 400 }, rot: 1.5 },
+    ],
+};
+
+const deltaData = compressor.compress(syncData);
+// deltaData only contains changed fields
+
+// Decompress delta data
+const fullData = compressor.decompress(deltaData);
+```
+
+## Configuration Options
+
+| Property | Type | Default | Description |
+|----------|------|---------|-------------|
+| `positionThreshold` | `number` | 0.01 | Position change threshold |
+| `rotationThreshold` | `number` | 0.001 | Rotation change threshold (radians) |
+| `velocityThreshold` | `number` | 0.1 | Velocity change threshold |
+| `fullSnapshotInterval` | `number` | 60 | Full snapshot interval (frames) |
+
+## Delta Flags
+
+Bit flags indicate which fields have changed:
+
+```typescript
+import { DeltaFlags } from '@esengine/network';
+
+// Flag definitions
+DeltaFlags.NONE           // 0 - No change
+DeltaFlags.POSITION       // 1 - Position changed
+DeltaFlags.ROTATION       // 2 - Rotation changed
+DeltaFlags.VELOCITY       // 4 - Velocity changed
+DeltaFlags.ANGULAR_VELOCITY // 8 - Angular velocity changed
+DeltaFlags.CUSTOM         // 16 - Custom data changed
+```
+
+## Data Format
+
+### Full State
+
+```typescript
+interface EntitySyncState {
+    netId: number;
+    pos?: { x: number; y: number };
+    rot?: number;
+    vel?: { x: number; y: number };
+    angVel?: number;
+    custom?: Record<string, unknown>;
+}
+```
+
+### Delta State
+
+```typescript
+interface EntityDeltaState {
+    netId: number;
+    flags: number;        // Change flags
+    pos?: { x: number; y: number };   // Only present when POSITION flag set
+    rot?: number;         // Only present when ROTATION flag set
+    vel?: { x: number; y: number };   // Only present when VELOCITY flag set
+    angVel?: number;      // Only present when ANGULAR_VELOCITY flag set
+    custom?: Record<string, unknown>; // Only present when CUSTOM flag set
+}
+```
+
+## How It Works
+
+```
+Frame 1 (full snapshot):
+  Entity 1: pos=(100, 200), rot=0
+
+Frame 2 (delta):
+  Entity 1: flags=POSITION, pos=(101, 200)  // Only X changed
+
+Frame 3 (delta):
+  Entity 1: flags=0  // No change, not sent
+
+Frame 4 (delta):
+  Entity 1: flags=POSITION|ROTATION, pos=(105, 200), rot=0.5
+
+Frame 60 (forced full snapshot):
+  Entity 1: pos=(200, 300), rot=1.0, vel=(5, 0)
+```
+
+## Server-Side Usage
+
+```typescript
+import { createStateDeltaCompressor } from '@esengine/network';
+
+class GameServer {
+    private compressor = createStateDeltaCompressor();
+
+    // Broadcast state updates
+    broadcastState(entities: EntitySyncState[]) {
+        const syncData: SyncData = {
+            frame: this.currentFrame,
+            timestamp: Date.now(),
+            entities,
+        };
+
+        // Compress data
+        const deltaData = this.compressor.compress(syncData);
+
+        // Send delta data
+        this.broadcast('sync', deltaData);
+    }
+
+    // Cleanup when player leaves
+    onPlayerLeave(netId: number) {
+        this.compressor.removeEntity(netId);
+    }
+}
+```
+
+## Client-Side Usage
+
+```typescript
+class GameClient {
+    private compressor = createStateDeltaCompressor();
+
+    // Receive delta data
+    onSyncReceived(deltaData: DeltaSyncData) {
+        // Decompress to full state
+        const fullData = this.compressor.decompress(deltaData);
+
+        // Apply state
+        for (const entity of fullData.entities) {
+            this.applyEntityState(entity);
+        }
+    }
+}
+```
+
+## Bandwidth Savings Example
+
+Assume each entity has the following data:
+
+| Field | Size (bytes) |
+|-------|-------------|
+| netId | 4 |
+| pos.x | 8 |
+| pos.y | 8 |
+| rot | 8 |
+| vel.x | 8 |
+| vel.y | 8 |
+| angVel | 8 |
+| **Total** | **52** |
+
+With delta compression:
+
+| Scenario | Original | Compressed | Savings |
+|----------|----------|------------|---------|
+| Only position changed | 52 | 4+1+16 = 21 | 60% |
+| Only rotation changed | 52 | 4+1+8 = 13 | 75% |
+| Stationary | 52 | 0 | 100% |
+| Position + rotation changed | 52 | 4+1+24 = 29 | 44% |
+
+## Forcing Full Snapshot
+
+Some situations require sending full snapshots:
+
+```typescript
+// When new player joins
+compressor.forceFullSnapshot();
+const data = compressor.compress(syncData);
+// This will send full state
+
+// On reconnection
+compressor.clear();  // Clear history
+compressor.forceFullSnapshot();
+```
+
+## Custom Data
+
+Support for syncing custom game data:
+
+```typescript
+const syncData: SyncData = {
+    frame: 100,
+    timestamp: Date.now(),
+    entities: [
+        {
+            netId: 1,
+            pos: { x: 100, y: 200 },
+            custom: {
+                health: 80,
+                mana: 50,
+                buffs: ['speed', 'shield'],
+            },
+        },
+    ],
+};
+
+// Custom data is also delta compressed
+const deltaData = compressor.compress(syncData);
+```
+
+## Best Practices
+
+### 1. Set Appropriate Thresholds
+
+```typescript
+// High precision games (e.g., competitive)
+const compressor = createStateDeltaCompressor({
+    positionThreshold: 0.001,
+    rotationThreshold: 0.0001,
+});
+
+// Casual games
+const compressor = createStateDeltaCompressor({
+    positionThreshold: 0.1,
+    rotationThreshold: 0.01,
+});
+```
+
+### 2. Adjust Full Snapshot Interval
+
+```typescript
+// High reliability (unstable network)
+fullSnapshotInterval: 30,  // Full snapshot every 30 frames
+
+// Low bandwidth priority
+fullSnapshotInterval: 120, // Full snapshot every 120 frames
+```
+
+### 3. Combine with AOI
+
+```typescript
+// Filter with AOI first, then delta compress
+const filteredEntities = aoiSystem.filterSyncData(playerId, allEntities);
+const syncData = { frame, timestamp, entities: filteredEntities };
+const deltaData = compressor.compress(syncData);
+```
+
+### 4. Handle Entity Removal
+
+```typescript
+// Clean up compressor state when entity despawns
+function onEntityDespawn(netId: number) {
+    compressor.removeEntity(netId);
+}
+```
+

+
+## Debugging
+
+```typescript
+const compressor = createStateDeltaCompressor();
+
+// Check compression efficiency
+const original = syncData;
+const compressed = compressor.compress(original);
+
+console.log('Original entities:', original.entities.length);
+console.log('Compressed entities:', compressed.entities.length);
+console.log('Is full snapshot:', compressed.isFullSnapshot);
+
+// View each entity's changes
+for (const delta of compressed.entities) {
+    console.log(`Entity ${delta.netId}:`, {
+        hasPosition: !!(delta.flags & DeltaFlags.POSITION),
+        hasRotation: !!(delta.flags & DeltaFlags.ROTATION),
+        hasVelocity: !!(delta.flags & DeltaFlags.VELOCITY),

+    });
+}

+title: "Client Prediction"
+description: "Local input prediction and server reconciliation"
+---
+
+Client prediction is a key technique in networked games to reduce input latency. By immediately applying player inputs locally while waiting for server confirmation, games feel more responsive.
+
+## NetworkPredictionSystem
+
+`NetworkPredictionSystem` is an ECS system dedicated to handling local player prediction.
+
+### Basic Usage
+
+```typescript
+import { NetworkPlugin } from '@esengine/network';
+
+const networkPlugin = new NetworkPlugin({
+    enablePrediction: true,
+    predictionConfig: {
+        moveSpeed: 200,           // Movement speed (units/second)
+        maxUnacknowledgedInputs: 60,  // Max unacknowledged inputs
+        reconciliationThreshold: 0.5,  // Reconciliation threshold
+        reconciliationSpeed: 10,       // Reconciliation speed
+    }
+});
+
+await Core.installPlugin(networkPlugin);
+```
+
+### Setting Up Local Player
+
+After the local player entity spawns, set its network ID:
+
+```typescript
+networkPlugin.registerPrefab('player', (scene, spawn) => {
+    const entity = scene.createEntity(`player_${spawn.netId}`);
+
+    const identity = entity.addComponent(new NetworkIdentity());
+    identity.netId = spawn.netId;
+    identity.ownerId = spawn.ownerId;
+    identity.bHasAuthority = spawn.ownerId === networkPlugin.localPlayerId;
+    identity.bIsLocalPlayer = identity.bHasAuthority;
+
+    entity.addComponent(new NetworkTransform());
+
+    // Set local player for prediction
+    if (identity.bIsLocalPlayer) {
+        networkPlugin.setLocalPlayerNetId(spawn.netId);
+    }
+
+    return entity;
+});
+```
+
+### Sending Input
+
+```typescript
+// Send movement input in game loop
+function onUpdate() {
+    const moveX = Input.getAxis('horizontal');
+    const moveY = Input.getAxis('vertical');
+
+    if (moveX !== 0 || moveY !== 0) {
+        networkPlugin.sendMoveInput(moveX, moveY);
+    }
+
+    // Send action input
+    if (Input.isPressed('attack')) {
+        networkPlugin.sendActionInput('attack');
+    }
+}
+```
+
+## Prediction Configuration
+
+| Property | Type | Default | Description |
+|----------|------|---------|-------------|
+| `moveSpeed` | `number` | 200 | Movement speed (units/second) |
+| `enabled` | `boolean` | true | Whether prediction is enabled |
+| `maxUnacknowledgedInputs` | `number` | 60 | Max unacknowledged inputs |
+| `reconciliationThreshold` | `number` | 0.5 | Position difference threshold for reconciliation |
+| `reconciliationSpeed` | `number` | 10 | Reconciliation smoothing speed |

+
+### Step by Step
+
+1. **Input Capture**: Capture player input and assign sequence number
+2. **Local Prediction**: Immediately apply input to local state
+3. **Send Input**: Send input to server
+4. **Cache Input**: Save input for later reconciliation
+5. **Receive Acknowledgment**: Server returns authoritative state with ack sequence
+6. **State Comparison**: Compare predicted state with server state
+7. **Input Replay**: Recalculate state using cached unacknowledged inputs
+8. **Smooth Correction**: Interpolate smoothly to correct position
+
+## Low-Level API
+
+For fine-grained control, use the `ClientPrediction` class directly:
+
+```typescript
+import { createClientPrediction, type IPredictor } from '@esengine/network';
+
+// Define state type
+interface PlayerState {
+    x: number;
+    y: number;
+    rotation: number;
+}
+
+// Define input type
+interface PlayerInput {
+    dx: number;
+    dy: number;
+}
+
+// Define predictor
+const predictor: IPredictor<PlayerState, PlayerInput> = {
+    predict(state: PlayerState, input: PlayerInput, dt: number): PlayerState {
+        return {
+            x: state.x + input.dx * MOVE_SPEED * dt,
+            y: state.y + input.dy * MOVE_SPEED * dt,
+            rotation: state.rotation,
+        };
+    }
+};
+
+// Create client prediction
+const prediction = createClientPrediction(predictor, {
+    maxUnacknowledgedInputs: 60,
+    reconciliationThreshold: 0.5,
+    reconciliationSpeed: 10,
+});
+
+// Record input and get predicted state
+const input = { dx: 1, dy: 0 };
+const predictedState = prediction.recordInput(input, currentState, deltaTime);
+
+// Get input to send
+const inputToSend = prediction.getInputToSend();
+
+// Reconcile with server state
+prediction.reconcile(
+    serverState,
+    serverAckSeq,
+    (state) => ({ x: state.x, y: state.y }),
+    deltaTime
+);
+
+// Get correction offset
+const offset = prediction.correctionOffset;
+```
+
+## Enable/Disable Prediction
+
+```typescript
+// Toggle prediction at runtime
+networkPlugin.setPredictionEnabled(false);
+
+// Check prediction status
+if (networkPlugin.isPredictionEnabled) {
+    console.log('Prediction is active');
+}
+```
+
+## Best Practices
+
+### 1. Set Appropriate Reconciliation Threshold
+
+```typescript
+// Action games: lower threshold, more precise
+predictionConfig: {
+    reconciliationThreshold: 0.1,
+}
+
+// Casual games: higher threshold, smoother
+predictionConfig: {
+    reconciliationThreshold: 1.0,
+}
+```
+
+### 2. Prediction Only for Local Player
+
+Remote players should use interpolation, not prediction:
+
+```typescript
+const identity = entity.getComponent(NetworkIdentity);
+
+if (identity.bIsLocalPlayer) {
+    // Use prediction system
+} else {
+    // Use NetworkSyncSystem interpolation
+}
+```
+
+### 3. Handle High Latency
+
+```typescript
+// High latency network: increase buffer
+predictionConfig: {
+    maxUnacknowledgedInputs: 120,  // Increase buffer
+    reconciliationSpeed: 5,        // Slower correction
+}
+```
+
+### 4. Deterministic Prediction
+
+Ensure client and server use the same physics calculations:
+
+```typescript
+// Use fixed timestep
+const FIXED_DT = 1 / 60;
+
+function applyInput(state: PlayerState, input: PlayerInput): PlayerState {
+    // Use fixed timestep instead of actual deltaTime
+    return {
+        x: state.x + input.dx * MOVE_SPEED * FIXED_DT,
+        y: state.y + input.dy * MOVE_SPEED * FIXED_DT,
+        rotation: state.rotation,
+    };
+}
+```
+
+## Debugging
+
+```typescript
+// Get prediction system instance
+const predictionSystem = networkPlugin.predictionSystem;
+
+if (predictionSystem) {
+    console.log('Pending inputs:', predictionSystem.pendingInputCount);
+    console.log('Current sequence:', predictionSystem.inputSequence);
+}
+```

+---
+
+## 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
+
+```

+    }
+
+    private async saveItem(ctx: ITransactionContext, item: any) {

+
+## 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) => {

+            },
+        },
+
+        // 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
+import { BaseOperation, ITransactionContext, OperationResult } from '@esengine/transaction';
+
+class MyOperation extends BaseOperation<MyData, MyResult> {
+    readonly name = 'myOperation';

+
+## CurrencyOperation
+
+Handles currency addition and deduction.
+
+### Deduct Currency
+
+```typescript
+import { CurrencyOperation } from '@esengine/transaction';
+
+tx.addOperation(new CurrencyOperation({
+    type: 'deduct',
+    playerId: 'player1',
+    currency: 'gold',
+    amount: 100,
+    reason: 'purchase_item',
+}));
+```
+
+### Add Currency
+
+```typescript
+tx.addOperation(new CurrencyOperation({
+    type: 'add',
+    playerId: 'player1',
+    currency: 'diamond',
+    amount: 50,
+    reason: 'daily_reward',
+}));
+```
+
+### Operation Data
+
+```typescript
+interface CurrencyOperationData {
+    type: 'add' | 'deduct';   // Operation type
+    playerId: string;          // Player ID
+    currency: string;          // Currency type
+    amount: number;            // Amount
+    reason?: string;           // Reason/source
+}
+```
+
+### Operation Result
+
+```typescript
+interface CurrencyOperationResult {
+    beforeBalance: number;     // Balance before operation
+    afterBalance: number;      // Balance after operation
+}
+```
+
+### Custom Data Provider
+
+```typescript
+interface ICurrencyProvider {
+    getBalance(playerId: string, currency: string): Promise<number>;
+    setBalance(playerId: string, currency: string, amount: number): Promise<void>;
+}
+
+class MyCurrencyProvider implements ICurrencyProvider {
+    async getBalance(playerId: string, currency: string): Promise<number> {
+        // Get balance from database
+        return await db.getCurrency(playerId, currency);
+    }
+
+    async setBalance(playerId: string, currency: string, amount: number): Promise<void> {
+        // Save to database
+        await db.setCurrency(playerId, currency, amount);
+    }
+}
+
+// Use custom provider
+const op = new CurrencyOperation({ ... });
+op.setProvider(new MyCurrencyProvider());
+tx.addOperation(op);
+```
+
+## InventoryOperation
+
+Handles item addition, removal, and updates.
+
+### Add Item
+
+```typescript
+import { InventoryOperation } from '@esengine/transaction';
+
+tx.addOperation(new InventoryOperation({
+    type: 'add',
+    playerId: 'player1',
+    itemId: 'sword_001',
+    quantity: 1,
+    properties: { enchant: 'fire' },
+}));
+```
+
+### Remove Item
+
+```typescript
+tx.addOperation(new InventoryOperation({
+    type: 'remove',
+    playerId: 'player1',
+    itemId: 'potion_hp',
+    quantity: 5,
+}));
+```
+
+### Update Item
+
+```typescript
+tx.addOperation(new InventoryOperation({
+    type: 'update',
+    playerId: 'player1',
+    itemId: 'sword_001',
+    quantity: 1,  // Optional, keeps original if not provided
+    properties: { enchant: 'lightning', level: 5 },
+}));
+```
+
+### Operation Data
+
+```typescript
+interface InventoryOperationData {
+    type: 'add' | 'remove' | 'update';  // Operation type
+    playerId: string;                    // Player ID
+    itemId: string;                      // Item ID
+    quantity: number;                    // Quantity
+    properties?: Record<string, unknown>; // Item properties
+    reason?: string;                     // Reason/source
+}
+```
+
+### Operation Result
+
+```typescript
+interface InventoryOperationResult {
+    beforeItem?: ItemData;   // Item before operation
+    afterItem?: ItemData;    // Item after operation
+}
+
+interface ItemData {
+    itemId: string;
+    quantity: number;
+    properties?: Record<string, unknown>;
+}
+```
+
+### Custom Data Provider
+
+```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
+
+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 factory pattern with lazy connection.
+
+```typescript
+import { MongoClient } from 'mongodb';
+import { MongoStorage } from '@esengine/transaction';
+
+// Factory pattern: lazy connection, connects on first operation
+const storage = new MongoStorage({
+    factory: async () => {
+        const client = new MongoClient('mongodb://localhost:27017');
+        await client.connect();
+        return client;
+    },
+    database: 'game',
+    transactionCollection: 'transactions',  // Transaction log collection
+    dataCollection: 'transaction_data',     // Business data collection
+    lockCollection: 'transaction_locks',    // Lock collection
+});
+
+// Create indexes (run on first startup)
+await storage.ensureIndexes();
+
+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 MongoStorage({ ... });
+```
+
+### 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
+}
+```

+title: "兴趣区域管理 (AOI)"
+description: "基于视野范围的网络实体过滤"
+---
+
+AOI（Area of Interest，兴趣区域）是大规模多人游戏中用于优化网络带宽的关键技术。通过只同步玩家视野范围内的实体，可以大幅减少网络流量。
+
+## NetworkAOISystem
+
+`NetworkAOISystem` 提供基于网格的兴趣区域管理。
+
+### 启用 AOI
+
+```typescript
+import { NetworkPlugin } from '@esengine/network';
+
+const networkPlugin = new NetworkPlugin({
+    enableAOI: true,
+    aoiConfig: {
+        cellSize: 100,           // 网格单元大小
+        defaultViewRange: 500,   // 默认视野范围
+        enabled: true,
+    }
+});
+
+await Core.installPlugin(networkPlugin);
+```
+
+### 添加观察者
+
+每个需要接收同步数据的玩家都需要作为观察者添加：
+
+```typescript
+// 玩家加入时添加观察者
+networkPlugin.registerPrefab('player', (scene, spawn) => {
+    const entity = scene.createEntity(`player_${spawn.netId}`);
+
+    // ... 设置组件
+
+    // 将玩家添加为 AOI 观察者
+    networkPlugin.addAOIObserver(
+        spawn.netId,     // 网络 ID
+        spawn.pos.x,     // 初始 X 位置
+        spawn.pos.y,     // 初始 Y 位置
+        600              // 视野范围（可选）
+    );
+
+    return entity;
+});
+
+// 玩家离开时移除观察者
+networkPlugin.removeAOIObserver(playerNetId);
+```
+
+### 更新观察者位置
+
+当玩家移动时，需要更新其 AOI 位置：
+
+```typescript
+// 在游戏循环或同步回调中更新
+networkPlugin.updateAOIObserverPosition(playerNetId, newX, newY);
+```
+
+## AOI 配置
+
+| 属性 | 类型 | 默认值 | 描述 |
+|------|------|--------|------|
+| `cellSize` | `number` | 100 | 网格单元大小 |
+| `defaultViewRange` | `number` | 500 | 默认视野范围 |
+| `enabled` | `boolean` | true | 是否启用 AOI |
+
+### 网格大小建议
+
+网格大小应根据游戏视野范围设置：
+
+```typescript
+// 建议：cellSize = defaultViewRange / 3 到 / 5
+aoiConfig: {
+    cellSize: 100,
+    defaultViewRange: 500,  // 网格大约是视野的 1/5
+}
+```
+
+## 查询接口
+
+### 获取可见实体
+
+```typescript
+// 获取玩家能看到的所有实体
+const visibleEntities = networkPlugin.getVisibleEntities(playerNetId);
+console.log('Visible entities:', visibleEntities);
+```
+
+### 检查可见性
+
+```typescript
+// 检查玩家是否能看到某个实体
+if (networkPlugin.canSee(playerNetId, targetEntityNetId)) {
+    // 目标在视野内
+}
+```
+
+## 事件监听
+
+AOI 系统会在实体进入/离开视野时触发事件：
+
+```typescript
+const aoiSystem = networkPlugin.aoiSystem;
+
+if (aoiSystem) {
+    aoiSystem.addListener((event) => {
+        if (event.type === 'enter') {
+            console.log(`Entity ${event.targetNetId} entered view of ${event.observerNetId}`);
+            // 可以在这里发送实体的初始状态
+        } else if (event.type === 'exit') {
+            console.log(`Entity ${event.targetNetId} left view of ${event.observerNetId}`);
+            // 可以在这里清理资源
+        }
+    });
+}
+```
+
+## 服务器端过滤
+
+AOI 最常用于服务器端，过滤发送给每个客户端的同步数据：
+
+```typescript
+// 服务器端示例
+import { NetworkAOISystem, createNetworkAOISystem } from '@esengine/network';
+
+class GameServer {
+    private aoiSystem = createNetworkAOISystem({
+        cellSize: 100,
+        defaultViewRange: 500,
+    });
+
+    // 玩家加入
+    onPlayerJoin(playerId: number, x: number, y: number) {
+        this.aoiSystem.addObserver(playerId, x, y);
+    }
+
+    // 玩家移动
+    onPlayerMove(playerId: number, x: number, y: number) {
+        this.aoiSystem.updateObserverPosition(playerId, x, y);
+    }
+
+    // 发送同步数据
+    broadcastSync(allEntities: EntitySyncState[]) {
+        for (const playerId of this.players) {
+            // 使用 AOI 过滤
+            const filteredEntities = this.aoiSystem.filterSyncData(
+                playerId,
+                allEntities
+            );
+
+            // 只发送可见实体
+            this.sendToPlayer(playerId, { entities: filteredEntities });
+        }
+    }
+}
+```
+
+## 工作原理

+└─────────────────────────────────────────────────────────────┘
+```
+
+### 网格优化
+
+AOI 使用空间网格加速查询：
+
+1. **添加实体**：根据位置计算所在网格
+2. **视野检测**：只检查视野范围覆盖的网格
+3. **移动更新**：跨网格时更新网格归属
+4. **事件触发**：检测进入/离开视野
+
+## 动态视野范围
+
+可以为不同类型的玩家设置不同的视野：
+
+```typescript
+// 普通玩家
+networkPlugin.addAOIObserver(playerId, x, y, 500);
+
+// VIP 玩家（更大视野）
+networkPlugin.addAOIObserver(vipPlayerId, x, y, 800);
+
+// 运行时调整视野
+const aoiSystem = networkPlugin.aoiSystem;
+if (aoiSystem) {
+    aoiSystem.updateObserverViewRange(playerId, 600);
+}
+```
+
+## 最佳实践
+
+### 1. 服务器端使用
+
+AOI 过滤应在服务器端进行，客户端不应信任自己的 AOI 判断：
+
+```typescript
+// 服务器端过滤后再发送
+const filtered = aoiSystem.filterSyncData(playerId, entities);
+sendToClient(playerId, filtered);
+```
+
+### 2. 边界处理
+
+在视野边缘添加缓冲区防止闪烁：
+
+```typescript
+// 进入视野时立即添加
+// 离开视野时延迟移除（保持额外 1-2 秒）
+aoiSystem.addListener((event) => {
+    if (event.type === 'exit') {
+        setTimeout(() => {
+            // 再次检查是否真的离开
+            if (!aoiSystem.canSee(event.observerNetId, event.targetNetId)) {
+                removeFromClient(event.observerNetId, event.targetNetId);
+            }
+        }, 1000);
+    }
+});
+```
+
+### 3. 大型实体
+
+对于大型实体（如 Boss），可能需要特殊处理：
+
+```typescript
+// Boss 总是对所有人可见
+function filterWithBoss(playerId: number, entities: EntitySyncState[]) {
+    const filtered = aoiSystem.filterSyncData(playerId, entities);
+
+    // 添加 Boss 实体
+    const bossState = entities.find(e => e.netId === bossNetId);
+    if (bossState && !filtered.includes(bossState)) {
+        filtered.push(bossState);
+    }
+
+    return filtered;
+}
+```
+
+### 4. 性能考虑
+
+```typescript
+// 大规模游戏建议配置
+aoiConfig: {
+    cellSize: 200,           // 较大的网格减少网格数量
+    defaultViewRange: 800,   // 根据实际视野设置
+}
+```
+
+## 调试
+
+```typescript
+const aoiSystem = networkPlugin.aoiSystem;
+
+if (aoiSystem) {
+    console.log('AOI enabled:', aoiSystem.enabled);
+    console.log('Observer count:', aoiSystem.observerCount);
+
+    // 获取特定玩家的可见实体
+    const visible = aoiSystem.getVisibleEntities(playerId);
+    console.log('Visible entities:', visible.length);
+}
+```

+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)
+```
+
+### 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。

+title: "状态增量压缩"
+description: "减少网络带宽的增量同步"
+---
+
+状态增量压缩通过只发送变化的字段来减少网络带宽。对于频繁同步的游戏状态，这可以显著降低数据传输量。
+
+## StateDeltaCompressor
+
+`StateDeltaCompressor` 类用于压缩和解压状态增量。
+
+### 基本用法
+
+```typescript
+import { createStateDeltaCompressor, type SyncData } from '@esengine/network';
+
+// 创建压缩器
+const compressor = createStateDeltaCompressor({
+    positionThreshold: 0.01,      // 位置变化阈值
+    rotationThreshold: 0.001,     // 旋转变化阈值（弧度）
+    velocityThreshold: 0.1,       // 速度变化阈值
+    fullSnapshotInterval: 60,     // 完整快照间隔（帧数）
+});
+
+// 压缩同步数据
+const syncData: SyncData = {
+    frame: 100,
+    timestamp: Date.now(),
+    entities: [
+        { netId: 1, pos: { x: 100, y: 200 }, rot: 0 },
+        { netId: 2, pos: { x: 300, y: 400 }, rot: 1.5 },
+    ],
+};
+
+const deltaData = compressor.compress(syncData);
+// deltaData 只包含变化的字段
+
+// 解压增量数据
+const fullData = compressor.decompress(deltaData);
+```
+
+## 配置选项
+
+| 属性 | 类型 | 默认值 | 描述 |
+|------|------|--------|------|
+| `positionThreshold` | `number` | 0.01 | 位置变化阈值 |
+| `rotationThreshold` | `number` | 0.001 | 旋转变化阈值（弧度） |
+| `velocityThreshold` | `number` | 0.1 | 速度变化阈值 |
+| `fullSnapshotInterval` | `number` | 60 | 完整快照间隔（帧数） |
+
+## 增量标志
+
+使用位标志表示哪些字段发生了变化：
+
+```typescript
+import { DeltaFlags } from '@esengine/network';
+
+// 位标志定义
+DeltaFlags.NONE           // 0 - 无变化
+DeltaFlags.POSITION       // 1 - 位置变化
+DeltaFlags.ROTATION       // 2 - 旋转变化
+DeltaFlags.VELOCITY       // 4 - 速度变化
+DeltaFlags.ANGULAR_VELOCITY // 8 - 角速度变化
+DeltaFlags.CUSTOM         // 16 - 自定义数据变化
+```
+
+## 数据格式
+
+### 完整状态
+
+```typescript
+interface EntitySyncState {
+    netId: number;
+    pos?: { x: number; y: number };
+    rot?: number;
+    vel?: { x: number; y: number };
+    angVel?: number;
+    custom?: Record<string, unknown>;
+}
+```
+
+### 增量状态
+
+```typescript
+interface EntityDeltaState {
+    netId: number;
+    flags: number;        // 变化标志位
+    pos?: { x: number; y: number };   // 仅在 POSITION 标志时存在
+    rot?: number;         // 仅在 ROTATION 标志时存在
+    vel?: { x: number; y: number };   // 仅在 VELOCITY 标志时存在
+    angVel?: number;      // 仅在 ANGULAR_VELOCITY 标志时存在
+    custom?: Record<string, unknown>; // 仅在 CUSTOM 标志时存在
+}
+```
+
+## 工作原理
+
+```
+帧 1 (完整快照)：
+  Entity 1: pos=(100, 200), rot=0
+
+帧 2 (增量)：
+  Entity 1: flags=POSITION, pos=(101, 200)  // 只有 X 变化
+
+帧 3 (增量)：
+  Entity 1: flags=0  // 无变化，不发送
+
+帧 4 (增量)：
+  Entity 1: flags=POSITION|ROTATION, pos=(105, 200), rot=0.5
+
+帧 60 (强制完整快照)：
+  Entity 1: pos=(200, 300), rot=1.0, vel=(5, 0)
+```
+
+## 服务器端使用
+
+```typescript
+import { createStateDeltaCompressor } from '@esengine/network';
+
+class GameServer {
+    private compressor = createStateDeltaCompressor();
+
+    // 广播状态更新
+    broadcastState(entities: EntitySyncState[]) {
+        const syncData: SyncData = {
+            frame: this.currentFrame,
+            timestamp: Date.now(),
+            entities,
+        };
+
+        // 压缩数据
+        const deltaData = this.compressor.compress(syncData);
+
+        // 发送增量数据
+        this.broadcast('sync', deltaData);
+    }
+
+    // 玩家离开时清理
+    onPlayerLeave(netId: number) {
+        this.compressor.removeEntity(netId);
+    }
+}
+```
+
+## 客户端使用
+
+```typescript
+class GameClient {
+    private compressor = createStateDeltaCompressor();
+
+    // 接收增量数据
+    onSyncReceived(deltaData: DeltaSyncData) {
+        // 解压为完整状态
+        const fullData = this.compressor.decompress(deltaData);
+
+        // 应用状态
+        for (const entity of fullData.entities) {
+            this.applyEntityState(entity);
+        }
+    }
+}
+```
+
+## 带宽节省示例
+
+假设每个实体有以下数据：
+
+| 字段 | 大小（字节） |
+|------|------------|
+| netId | 4 |
+| pos.x | 8 |
+| pos.y | 8 |
+| rot | 8 |
+| vel.x | 8 |
+| vel.y | 8 |
+| angVel | 8 |
+| **总计** | **52** |
+
+使用增量压缩：
+
+| 场景 | 原始 | 压缩后 | 节省 |
+|------|------|--------|------|
+| 只有位置变化 | 52 | 4+1+16 = 21 | 60% |
+| 只有旋转变化 | 52 | 4+1+8 = 13 | 75% |
+| 静止不动 | 52 | 0 | 100% |
+| 位置+旋转变化 | 52 | 4+1+24 = 29 | 44% |
+
+## 强制完整快照
+
+某些情况下需要发送完整快照：
+
+```typescript
+// 新玩家加入时
+compressor.forceFullSnapshot();
+const data = compressor.compress(syncData);
+// 这次会发送完整状态
+
+// 重连时
+compressor.clear();  // 清除历史状态
+compressor.forceFullSnapshot();
+```
+
+## 自定义数据
+
+支持同步自定义游戏数据：
+
+```typescript
+const syncData: SyncData = {
+    frame: 100,
+    timestamp: Date.now(),
+    entities: [
+        {
+            netId: 1,
+            pos: { x: 100, y: 200 },
+            custom: {
+                health: 80,
+                mana: 50,
+                buffs: ['speed', 'shield'],
+            },
+        },
+    ],
+};
+
+// 自定义数据也会进行增量压缩
+const deltaData = compressor.compress(syncData);
+```
+
+## 最佳实践
+
+### 1. 合理设置阈值
+
+```typescript
+// 高精度游戏（如竞技游戏）
+const compressor = createStateDeltaCompressor({
+    positionThreshold: 0.001,
+    rotationThreshold: 0.0001,
+});
+
+// 普通游戏
+const compressor = createStateDeltaCompressor({
+    positionThreshold: 0.1,
+    rotationThreshold: 0.01,
+});
+```
+
+### 2. 调整完整快照间隔
+
+```typescript
+// 高可靠性（网络不稳定）
+fullSnapshotInterval: 30,  // 每 30 帧发送完整快照
+
+// 低带宽优先
+fullSnapshotInterval: 120, // 每 120 帧发送完整快照
+```
+
+### 3. 配合 AOI 使用
+
+```typescript
+// 先用 AOI 过滤，再用增量压缩
+const filteredEntities = aoiSystem.filterSyncData(playerId, allEntities);
+const syncData = { frame, timestamp, entities: filteredEntities };
+const deltaData = compressor.compress(syncData);
+```
+
+### 4. 处理实体移除
+
+```typescript
+// 实体销毁时清理压缩器状态
+function onEntityDespawn(netId: number) {
+    compressor.removeEntity(netId);
+}
+```
+
+## 与其他功能配合
+
+```

+                    │    游戏状态      │

+                    └─────────────────┘
+```
+
+## 调试
+
+```typescript
+const compressor = createStateDeltaCompressor();
+
+// 检查压缩效果
+const original = syncData;
+const compressed = compressor.compress(original);
+
+console.log('Original entities:', original.entities.length);
+console.log('Compressed entities:', compressed.entities.length);
+console.log('Is full snapshot:', compressed.isFullSnapshot);
+
+// 查看每个实体的变化
+for (const delta of compressed.entities) {
+    console.log(`Entity ${delta.netId}:`, {
+        hasPosition: !!(delta.flags & DeltaFlags.POSITION),
+        hasRotation: !!(delta.flags & DeltaFlags.ROTATION),
+        hasVelocity: !!(delta.flags & DeltaFlags.VELOCITY),
+        hasCustom: !!(delta.flags & DeltaFlags.CUSTOM),
+    });
+}
+```

+title: "客户端预测"
+description: "本地输入预测和服务器校正"
+---
+
+客户端预测是网络游戏中用于减少输入延迟的关键技术。通过在本地立即应用玩家输入，同时等待服务器确认，可以让游戏感觉更加流畅响应。
+
+## NetworkPredictionSystem
+
+`NetworkPredictionSystem` 是专门处理本地玩家预测的 ECS 系统。
+
+### 基本用法
+
+```typescript
+import { NetworkPlugin } from '@esengine/network';
+
+const networkPlugin = new NetworkPlugin({
+    enablePrediction: true,
+    predictionConfig: {
+        moveSpeed: 200,           // 移动速度（单位/秒）
+        maxUnacknowledgedInputs: 60,  // 最大未确认输入数
+        reconciliationThreshold: 0.5,  // 校正阈值
+        reconciliationSpeed: 10,       // 校正速度
+    }
+});
+
+await Core.installPlugin(networkPlugin);
+```
+
+### 设置本地玩家
+
+当本地玩家实体生成后，需要设置其网络 ID：
+
+```typescript
+networkPlugin.registerPrefab('player', (scene, spawn) => {
+    const entity = scene.createEntity(`player_${spawn.netId}`);
+
+    const identity = entity.addComponent(new NetworkIdentity());
+    identity.netId = spawn.netId;
+    identity.ownerId = spawn.ownerId;
+    identity.bHasAuthority = spawn.ownerId === networkPlugin.localPlayerId;
+    identity.bIsLocalPlayer = identity.bHasAuthority;
+
+    entity.addComponent(new NetworkTransform());
+
+    // 设置本地玩家用于预测
+    if (identity.bIsLocalPlayer) {
+        networkPlugin.setLocalPlayerNetId(spawn.netId);
+    }
+
+    return entity;
+});
+```
+
+### 发送输入
+
+```typescript
+// 在游戏循环中发送移动输入
+function onUpdate() {
+    const moveX = Input.getAxis('horizontal');
+    const moveY = Input.getAxis('vertical');
+
+    if (moveX !== 0 || moveY !== 0) {
+        networkPlugin.sendMoveInput(moveX, moveY);
+    }
+
+    // 发送动作输入
+    if (Input.isPressed('attack')) {
+        networkPlugin.sendActionInput('attack');
+    }
+}
+```
+
+## 预测配置
+
+| 属性 | 类型 | 默认值 | 描述 |
+|------|------|--------|------|
+| `moveSpeed` | `number` | 200 | 移动速度（单位/秒） |
+| `enabled` | `boolean` | true | 是否启用预测 |
+| `maxUnacknowledgedInputs` | `number` | 60 | 最大未确认输入数 |
+| `reconciliationThreshold` | `number` | 0.5 | 触发校正的位置差异阈值 |
+| `reconciliationSpeed` | `number` | 10 | 校正平滑速度 |

+2. **本地预测**：立即应用输入到本地状态
+3. **发送输入**：将输入发送到服务器
+4. **缓存输入**：保存输入用于后续校正
+5. **接收确认**：服务器返回权威状态和已确认序列号
+6. **状态比较**：比较预测状态和服务器状态
+7. **输入重放**：使用缓存的未确认输入重新计算状态
+8. **平滑校正**：平滑插值到正确位置
+
+## 底层 API
+
+如果需要更细粒度的控制，可以直接使用 `ClientPrediction` 类：
+
+```typescript
+import { createClientPrediction, type IPredictor } from '@esengine/network';
+
+// 定义状态类型
+interface PlayerState {
+    x: number;
+    y: number;
+    rotation: number;
+}
+
+// 定义输入类型
+interface PlayerInput {
+    dx: number;
+    dy: number;
+}
+
+// 定义预测器
+const predictor: IPredictor<PlayerState, PlayerInput> = {
+    predict(state: PlayerState, input: PlayerInput, dt: number): PlayerState {
+        return {
+            x: state.x + input.dx * MOVE_SPEED * dt,
+            y: state.y + input.dy * MOVE_SPEED * dt,
+            rotation: state.rotation,
+        };
+    }
+};
+
+// 创建客户端预测
+const prediction = createClientPrediction(predictor, {
+    maxUnacknowledgedInputs: 60,
+    reconciliationThreshold: 0.5,
+    reconciliationSpeed: 10,
+});
+
+// 记录输入并获取预测状态
+const input = { dx: 1, dy: 0 };
+const predictedState = prediction.recordInput(input, currentState, deltaTime);
+
+// 获取要发送的输入
+const inputToSend = prediction.getInputToSend();
+
+// 与服务器状态校正
+prediction.reconcile(
+    serverState,
+    serverAckSeq,
+    (state) => ({ x: state.x, y: state.y }),
+    deltaTime
+);
+
+// 获取校正偏移
+const offset = prediction.correctionOffset;
+```
+
+## 启用/禁用预测
+
+```typescript
+// 运行时切换预测
+networkPlugin.setPredictionEnabled(false);
+
+// 检查预测状态
+if (networkPlugin.isPredictionEnabled) {
+    console.log('Prediction is active');
+}
+```
+
+## 最佳实践
+
+### 1. 合理设置校正阈值
+
+```typescript
+// 动作游戏：较低阈值，更精确
+predictionConfig: {
+    reconciliationThreshold: 0.1,
+}
+
+// 休闲游戏：较高阈值，更平滑
+predictionConfig: {
+    reconciliationThreshold: 1.0,
+}
+```
+
+### 2. 预测仅用于本地玩家
+
+远程玩家应使用插值而非预测：
+
+```typescript
+const identity = entity.getComponent(NetworkIdentity);
+
+if (identity.bIsLocalPlayer) {
+    // 使用预测系统
+} else {
+    // 使用 NetworkSyncSystem 的插值
+}
+```
+
+### 3. 处理高延迟
+
+```typescript
+// 高延迟网络增加缓冲
+predictionConfig: {
+    maxUnacknowledgedInputs: 120,  // 增加缓冲
+    reconciliationSpeed: 5,        // 减慢校正速度
+}
+```
+
+### 4. 确定性预测
+
+确保客户端和服务器使用相同的物理计算：
+
+```typescript
+// 使用固定时间步长
+const FIXED_DT = 1 / 60;
+
+function applyInput(state: PlayerState, input: PlayerInput): PlayerState {
+    // 使用固定时间步长而非实际 deltaTime
+    return {
+        x: state.x + input.dx * MOVE_SPEED * FIXED_DT,
+        y: state.y + input.dy * MOVE_SPEED * FIXED_DT,
+        rotation: state.rotation,
+    };
+}
+```
+
+## 调试
+
+```typescript
+// 获取预测系统实例
+const predictionSystem = networkPlugin.predictionSystem;
+
+if (predictionSystem) {
+    console.log('Pending inputs:', predictionSystem.pendingInputCount);
+    console.log('Current sequence:', predictionSystem.inputSequence);
+}
+```

+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
+
+```

+    }
+
+    private async saveItem(ctx: ITransactionContext, item: any) {

+
+## 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

+## 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

+
+    // 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) => {

+            },
+            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',
+    amount: 100,

+
+### 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
+}
+```

+
+// 使用自定义提供者
+const op = new CurrencyOperation({ ... });
+op.setProvider(new MyCurrencyProvider());

+```
+
+## 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[]>;

+    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。使用工厂模式实现惰性连接。
+
+```typescript
+import { MongoClient } from 'mongodb';
+import { MongoStorage } from '@esengine/transaction';
+
+// 工厂模式：惰性连接，首次操作时才创建连接
+const storage = new MongoStorage({
+    factory: async () => {
+        const client = new MongoClient('mongodb://localhost:27017');
+        await client.connect();
+        return client;
+    },
+    database: 'game',
+    transactionCollection: 'transactions',  // 事务日志集合
+    dataCollection: 'transaction_data',     // 业务数据集合
+    lockCollection: 'transaction_locks',    // 锁集合
+});
+
+// 创建索引（首次运行时执行）
+await storage.ensureIndexes();
+
+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 MongoStorage({ ... });
+```
+
+### 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
+}
+```

+## 2.0.1
+
+### Patch Changes
+
+- Updated dependencies [[`61a13ba`](https://github.com/esengine/esengine/commit/61a13baca2e1e8fba14e23d439521ec0e6b7ca6e)]:
+    - @esengine/server@1.2.0
+
+## 2.0.0
+
+### Major Changes
+
+- [#384](https://github.com/esengine/esengine/pull/384) [`3b97838`](https://github.com/esengine/esengine/commit/3b978384c7d4570f9af9d139e3bfea04c6875543) Thanks [@esengine](https://github.com/esengine)! - ## Breaking Changes
+
+    ### Storage API Simplification
+
+    RedisStorage and MongoStorage now use **factory pattern only** for connection management. The direct client injection option has been removed.
+
+    **Before (removed):**
+
+    ```typescript
+    // Direct client injection - NO LONGER SUPPORTED
+    const storage = new RedisStorage({ client: redisClient });
+    const storage = new MongoStorage({ client: mongoClient, database: 'game' });
+    ```
+
+    **After (factory pattern only):**
+
+    ```typescript
+    // RedisStorage
+    const storage = new RedisStorage({
+        factory: () => new Redis('redis://localhost:6379'),
+        prefix: 'tx:',
+        transactionTTL: 86400
+    });
+
+    // MongoStorage
+    const storage = new MongoStorage({
+        factory: async () => {
+            const client = new MongoClient('mongodb://localhost:27017');
+            await client.connect();
+            return client;
+        },
+        database: 'game'
+    });
+    ```
+
+    ### New Features
+    - **Lazy Connection**: Connection is established on first operation, not at construction time
+    - **Automatic Cleanup**: Support `await using` syntax (TypeScript 5.2+) for automatic resource cleanup
+    - **Explicit Close**: Call `storage.close()` when done, or use `await using` for automatic disposal
+
+    ### Migration Guide
+    1. Replace `client` option with `factory` function
+    2. Add `storage.close()` call when done, or use `await using`
+    3. For MongoStorage, ensure factory returns a connected client
+
