2.1.1

Patch Changes

• Updated dependencies [85171a0]:
  • @esengine/database-drivers@1.1.1

2.1.0

Minor Changes

• #410 71022ab Thanks @esengine! - feat: add database layer architecture

  Added new database packages with layered architecture:

  @esengine/database-drivers (Layer 1)

  • MongoDB connection with pool management, auto-reconnect, events
  • Redis connection with auto-reconnect, key prefix
  • Type-safe IMongoCollection<T> interface decoupled from mongodb types
  • Service tokens for dependency injection (MongoConnectionToken, RedisConnectionToken)

  @esengine/database (Layer 2)

  • Generic Repository<T> with CRUD, pagination, soft delete
  • UserRepository with registration, authentication, role management
  • Password hashing utilities using scrypt
  • Query operators: $eq, $ne, $gt, $gte, $lt, $lte, $in, $nin, $like, $regex

  @esengine/transaction

  • Refactored MongoStorage to use shared connection from @esengine/database-drivers
  • Removed factory pattern in favor of shared connection (breaking change)
  • Simplified API: createMongoStorage(connection, options?)

  Example usage:

  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 });

Major Changes

• #384 3b97838 Thanks @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):

  // Direct client injection - NO LONGER SUPPORTED
  const storage = new RedisStorage({ client: redisClient });
  const storage = new MongoStorage({ client: mongoClient, database: 'game' });
  

  After (factory pattern only):

  // 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
