Nestjs集成redis

一、安装

yarn add redis

 二、使用

1.在module中注册

import { createClient } from 'redis'

@Module({
    providers:[{
      provide: 'REDIS_CLIENT',// 定义一个服务提供者
      // 创建 Redis 客户端实例
      async useFactory() {
        const client = createClient({
          socket: {
            host: '127.0.0.1',
            port: 6379,
          }
        })
        await client.connect()
        return client;
      }
    }]
})

2.在 service中使用

import { Injectable, Inject } from '@nestjs/common';
import { RedisClientType } from 'redis';

@Injectable()
export class AppService {
  @Inject('REDIS_CLIENT')
  private redisClient: RedisClientType;

  async getHello() {
    // 获取所有值
    const value = await this.redisClient.keys('*');

    // 设置值
    const setvalue = await this.redisClient.set('demo', '11111');

    // 获取值
    const getvalue = await this.redisClient.get('demo');

    // 删除值 1代表成功 0代表没有
    const delvalue = await this.redisClient.del('demo');

    // 定时设置值 10s
    const setTimevalue = await this.redisClient.set('demo', '11111', { EX: 10 })
    return 'Hello World!';
  }
}
