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

+
+## Quick Start
+
+### MongoDB Connection
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers'
+
+// Create connection
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game',
+    pool: {
+        minSize: 5,
+        maxSize: 20
+    },
+    autoReconnect: true
+})
+
+// Listen to events
+mongo.on('connected', () => console.log('MongoDB connected'))
+mongo.on('disconnected', () => console.log('MongoDB disconnected'))
+mongo.on('error', (e) => console.error('Error:', e.error))
+
+// Connect
+await mongo.connect()
+
+// Use collections
+const users = mongo.collection<User>('users')
+await users.insertOne({ name: 'John', score: 100 })
+
+const user = await users.findOne({ name: 'John' })
+
+// Disconnect when done
+await mongo.disconnect()
+```
+
+### Redis Connection
+
+```typescript
+import { createRedisConnection } from '@esengine/database-drivers'
+
+const redis = createRedisConnection({
+    host: 'localhost',
+    port: 6379,
+    keyPrefix: 'game:',
+    autoReconnect: true
+})
+
+await redis.connect()
+
+// Basic operations
+await redis.set('session:123', 'data', 3600)  // With TTL
+const value = await redis.get('session:123')
+
+await redis.disconnect()
+```
+
+## Service Container Integration
+
+```typescript
+import { ServiceContainer } from '@esengine/ecs-framework'
+import {
+    createMongoConnection,
+    MongoConnectionToken,
+    RedisConnectionToken
+} from '@esengine/database-drivers'
+
+const services = new ServiceContainer()
+
+// Register connections
+const mongo = createMongoConnection({ uri: '...', database: 'game' })
+await mongo.connect()
+services.register(MongoConnectionToken, mongo)
+
+// Retrieve in other modules
+const connection = services.get(MongoConnectionToken)
+const users = connection.collection('users')
+```

+
+## Installation
+
+```bash
+npm install @esengine/database @esengine/database-drivers
+```
+
+## Quick Start
+
+### Basic Repository
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers'
+import { Repository, createRepository } from '@esengine/database'
+
+// Define entity
+interface Player {
+    id: string
+    name: string
+    score: number
+    createdAt: Date
+    updatedAt: Date
+}
+
+// Create connection
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game'
+})
+await mongo.connect()
+
+// Create repository
+const playerRepo = createRepository<Player>(mongo, 'players')
+
+// CRUD operations
+const player = await playerRepo.create({
+    name: 'John',
+    score: 0
+})
+
+const found = await playerRepo.findById(player.id)
+
+await playerRepo.update(player.id, { score: 100 })
+
+await playerRepo.delete(player.id)
+```
+
+### Custom Repository
+
+```typescript
+import { Repository, BaseEntity } from '@esengine/database'
+import type { IMongoConnection } from '@esengine/database-drivers'
+
+interface Player extends BaseEntity {
+    name: string
+    score: number
+    rank?: string
+}
+
+class PlayerRepository extends Repository<Player> {
+    constructor(connection: IMongoConnection) {
+        super(connection, 'players')
+    }
+
+    async findTopPlayers(limit: number = 10): Promise<Player[]> {
+        return this.findMany({
+            sort: { score: 'desc' },
+            limit
+        })
+    }
+
+    async findByRank(rank: string): Promise<Player[]> {
+        return this.findMany({
+            where: { rank }
+        })
+    }
+}
+
+// Usage
+const playerRepo = new PlayerRepository(mongo)
+const topPlayers = await playerRepo.findTopPlayers(5)
+```
+
+### User Repository
+
+```typescript
+import { UserRepository } from '@esengine/database'
+
+const userRepo = new UserRepository(mongo)
+
+// Register new user
+const user = await userRepo.register({
+    username: 'john',
+    password: 'securePassword123',
+    email: 'john@example.com'
+})
+
+// Authenticate
+const authenticated = await userRepo.authenticate('john', 'securePassword123')
+if (authenticated) {
+    console.log('Login successful:', authenticated.username)
+}
+
+// Change password
+await userRepo.changePassword(user.id, 'securePassword123', 'newPassword456')
+
+// Role management
+await userRepo.addRole(user.id, 'admin')
+await userRepo.removeRole(user.id, 'admin')
+
+// Find users
+const admins = await userRepo.findByRole('admin')
+const john = await userRepo.findByUsername('john')
+```
+
+### Pagination
+
+```typescript
+const result = await playerRepo.findPaginated(
+    { page: 1, pageSize: 20 },
+    {
+        where: { rank: 'gold' },
+        sort: { score: 'desc' }
+    }
+)
+
+console.log(result.data)        // Player[]
+console.log(result.total)       // Total count
+console.log(result.totalPages)  // Total pages
+console.log(result.hasNext)     // Has next page
+console.log(result.hasPrev)     // Has previous page
+```
+
+### Soft Delete
+
+```typescript
+// Enable soft delete
+const playerRepo = createRepository<Player>(mongo, 'players', true)
+
+// Delete (marks as deleted)
+await playerRepo.delete(playerId)
+
+// Find excludes soft-deleted by default
+const players = await playerRepo.findMany()
+
+// Include soft-deleted records
+const allPlayers = await playerRepo.findMany({
+    includeSoftDeleted: true
+})
+
+// Restore soft-deleted record
+await playerRepo.restore(playerId)
+```
+
+### Query Options
+
+```typescript
+// Complex queries
+const players = await playerRepo.findMany({
+    where: {
+        score: { $gte: 100 },
+        rank: { $in: ['gold', 'platinum'] },
+        name: { $like: 'John%' }
+    },
+    sort: {
+        score: 'desc',
+        name: 'asc'
+    },
+    limit: 10,
+    offset: 0
+})
+
+// OR conditions
+const players = await playerRepo.findMany({
+    where: {
+        $or: [
+            { score: { $gte: 1000 } },
+            { rank: 'legendary' }
+        ]
+    }
+})
+```
+
+## Query Operators
+
+| Operator | Description | Example |
+|----------|-------------|---------|
+| `$eq` | Equal | `{ score: { $eq: 100 } }` |
+| `$ne` | Not equal | `{ status: { $ne: 'banned' } }` |
+| `$gt` | Greater than | `{ score: { $gt: 50 } }` |
+| `$gte` | Greater or equal | `{ level: { $gte: 10 } }` |
+| `$lt` | Less than | `{ age: { $lt: 18 } }` |

+### MongoDB 连接
+
+```typescript
+import { createMongoConnection } from '@esengine/database-drivers'
+
+// 创建连接
+const mongo = createMongoConnection({
+    uri: 'mongodb://localhost:27017',
+    database: 'game',

+
+## IMongoCollection 接口
+
+类型安全的集合接口，与原生 MongoDB 类型解耦：
+
+```typescript
+interface IMongoCollection<T extends object> {

+
+    // 查询
+    findOne(filter: object, options?: FindOptions): Promise<T | null>

+
+    // 更新
+    updateOne(filter: object, update: object): Promise<UpdateResult>

+    createIndex(
+        spec: Record<string, 1 | -1>,
+        options?: IndexOptions
+    ): Promise<string>
+}
+```
+
+## 使用示例
+
+### 基本 CRUD
+
+```typescript

+    name: string
+    email: string
+    score: number
+}
+
+const users = mongo.collection<User>('users')

+    id: '1',
+    name: 'John',
+    email: 'john@example.com',
+    score: 100
+})
+
+// 查询
+const user = await users.findOne({ name: 'John' })
+
+const topUsers = await users.find(
+    { score: { $gte: 100 } },
+    { sort: { score: -1 }, limit: 10 }
+)
+
+// 更新
+await users.updateOne(
+    { id: '1' },
+    { $inc: { score: 10 } }
+)
+
+// 删除
+await users.deleteOne({ id: '1' })
+```
+
+### 批量操作
+
+```typescript
+// 批量插入
+await users.insertMany([
+    { id: '1', name: 'Alice', email: 'alice@example.com', score: 100 },
+    { id: '2', name: 'Bob', email: 'bob@example.com', score: 200 },
+    { id: '3', name: 'Carol', email: 'carol@example.com', score: 150 }
+])
+
+// 批量更新
+await users.updateMany(
+    { score: { $lt: 100 } },
+    { $set: { status: 'inactive' } }
+)
+
+// 批量删除
+await users.deleteMany({ status: 'inactive' })
+```
+
+### 索引管理
+
+```typescript
+// 创建索引
+await users.createIndex({ email: 1 }, { unique: true })
+await users.createIndex({ score: -1 })
+await users.createIndex({ name: 1, score: -1 })
+```
+
+## 与其他模块集成
+
+### 与 @esengine/database 集成

+
+// 获取剩余过期时间

+const redis = createRedisConnection({
+    host: 'localhost',
+    keyPrefix: 'game:'
+})
+

+
+// 实际查询的键是 'game:user:1'
+const data = await redis.get('user:1')
+```
+
+### 高级操作
+
+使用原生客户端进行高级操作：
+
+```typescript
+const client = redis.getNativeClient()
+
+// 使用 Pipeline
+const pipeline = client.pipeline()
+pipeline.set('key1', 'value1')
+pipeline.set('key2', 'value2')
+pipeline.set('key3', 'value3')
+await pipeline.exec()
+
+// 使用事务
+const multi = client.multi()
+multi.incr('counter')
+multi.get('counter')
+const results = await multi.exec()
+
+// 使用 Lua 脚本
+const result = await client.eval(
+    `return redis.call('get', KEYS[1])`,
+    1,
+    'mykey'
+)
+```
+
+## 与事务系统集成
+
+```typescript
+import { createRedisConnection } from '@esengine/database-drivers'
+import { RedisStorage, TransactionManager } from '@esengine/transaction'
+
+const redis = createRedisConnection({
+    host: 'localhost',
+    port: 6379,
+    keyPrefix: 'tx:'
+})
+await redis.connect()
+
+// 创建事务存储
+const storage = new RedisStorage({
+    factory: () => redis.getNativeClient(),
+    prefix: 'tx:'
+})
+
+const txManager = new TransactionManager({ storage })
+```
+
+## 连接状态
+
+```typescript
+type ConnectionState =
+    | 'disconnected'  // 未连接
+    | 'connecting'    // 连接中
+    | 'connected'     // 已连接
+    | 'disconnecting' // 断开中
+    | 'error'         // 错误状态
+```
+
+## 事件
+
+| 事件 | 描述 |
+|------|------|
+| `connected` | 连接成功 |
+| `disconnected` | 连接断开 |
+| `reconnecting` | 正在重连 |
+| `reconnected` | 重连成功 |

+
+## 逻辑操作符
+
+### $or
+
+```typescript
+await repo.findMany({
+    where: {
+        $or: [
+            { score: { $gte: 1000 } },
+            { rank: 'legendary' }
+        ]
+    }
+})
+```
+
+### $and
+
+```typescript
+await repo.findMany({
+    where: {
+        $and: [
+            { score: { $gte: 100 } },
+            { score: { $lte: 500 } }
+        ]
+    }
+})
+```
+
+### 组合使用
+
+```typescript
+await repo.findMany({
+    where: {
+        status: 'active',
+        $or: [
+            { rank: 'gold' },
+            { score: { $gte: 1000 } }
+        ]
+    }
+})
+```
+
+## 模式匹配
+
+### $like 语法
+
+- `%` - 匹配任意字符序列
+- `_` - 匹配单个字符
+
+```typescript
+// 以 'John' 开头
+{ name: { $like: 'John%' } }
+
+// 以 'son' 结尾
+{ name: { $like: '%son' } }
+
+// 包含 'oh'
+{ name: { $like: '%oh%' } }
+
+// 第二个字符是 'o'
+{ name: { $like: '_o%' } }
+```
+
+### $regex 语法
+
+使用标准正则表达式：
+
+```typescript
+// 以 'John' 开头（大小写不敏感）
+{ name: { $regex: '^john' } }
+
+// Gmail 邮箱
+{ email: { $regex: '@gmail\\.com$' } }
+
+// 包含数字
+{ username: { $regex: '\\d+' } }
+```
+
+## 排序
+
+```typescript
+await repo.findMany({
+    sort: {
+        score: 'desc',  // 降序
+        name: 'asc'     // 升序
+    }
+})
+```
+
+## 分页
+
+### 使用 limit/offset
+
+```typescript
+// 第一页
+await repo.findMany({
+    limit: 20,
+    offset: 0
+})
+
+// 第二页
+await repo.findMany({
+    limit: 20,
+    offset: 20
+})
+```
+
+### 使用 findPaginated
+
+```typescript
+const result = await repo.findPaginated(
+    { page: 2, pageSize: 20 },
+    { sort: { createdAt: 'desc' } }
+)
+```
+
+## 完整示例
+
+```typescript
+// 查找活跃的金牌玩家，分数在 100-1000 之间
+// 按分数降序排列，取前 10 个
+const players = await repo.findMany({
+    where: {
+        status: 'active',
+        rank: 'gold',
+        score: { $gte: 100, $lte: 1000 }
+    },
+    sort: { score: 'desc' },
+    limit: 10
+})
+
+// 搜索用户名包含 'john' 或邮箱是 gmail 的用户
+const users = await repo.findMany({
+    where: {
+        $or: [
+            { username: { $like: '%john%' } },
+            { email: { $regex: '@gmail\\.com$' } }
+        ]
+    }
+})

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