    "@nestjs/core": "^11.1.2",
    "@nestjs/platform-express": "^11.1.2",

  },

}

✅ Nest.js가 v11일 경우 Redis 셋팅 방법

1. 의존성 설치

$ npm install @keyv/redis

2. app.module.ts 셋팅 변경

import { Module } from "@nestjs/common";
import { TypeOrmModule } from "@nestjs/typeorm";
import { Board } from "./board.entity";
import { BoardController } from "./board.controller";
import { BoardService } from "./board.service";
import { CacheModule } from "@nestjs/cache-manager";
import KeyvRedis from "@keyv/redis";

@Module({
  imports: [
    TypeOrmModule.forRoot({
      type: 'mysql',
      host: 'localhost',
      port: 3306,
      username: 'root',
      password: 'password123',
      database: 'mydb',
      autoLoadEntities: true,
      synchronize: true,
    }),
    TypeOrmModule.forFeature([Board]),
    CacheModule.registerAsync({
      imports: undefined, useClass: undefined, useExisting: undefined,
      useFactory: async () => {
        return {
          stores: [
            new KeyvRedis('redis://localhost:6379'),
          ]
        }
      }
    }),
  ],
  controllers: [BoardController],
  providers: [BoardService],
})
export class AppModule {}

 

3. Service 로직 수정

@Injectable()
export class BoardService {
  constructor(
    @InjectRepository(Board)
    private boardRepository: Repository<Board>,
    @Inject(CACHE_MANAGER)
    private cacheManager: Cache,
  ) {}

  async getBoards(page: number, size: number): Promise<Board[]> {
    const cacheKey = `boards:page:${page}:size:${size}`;
    const cachedData = await this.cacheManager.get<Board[]>(cacheKey);
    if (cachedData) {
      return cachedData;
    }

    const skip = (page - 1) * size;
    const boards = await this.boardRepository.find({
      order: { createdAt: 'DESC' },
      skip: skip,
      take: size,
    });
    
    // ttl 값 추가 (단위 : milliseconds)
    await this.cacheManager.set(cacheKey, boards, 60 * 1000); 

    return boards;
  }
}

 

3. Redis-cli를 활용해 정상적으로 캐싱이 됐는 지 확인하기

$ redis-cli 

$ keys * # Redis에 저장되어 있는 모든 key 조회
$ get boards:page:1:size:10 # 특정 key의 Value 조회
$ ttl boards:page:1:size:10 # 특정 key의 TTL 조회
