Want to use Nestjs with other Redis command-CodePudding

I try to implement nestjs backend and redis as caching. I can do it according to the official document https://docs.nestjs.com/techniques/caching#in-memory-cache.

I use the package cache-manager-redis-store and the code in app.module.ts is as shown below.

import { Module, CacheModule } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import * as redisStore from 'cache-manager-redis-store';
import * as Joi from 'joi';
import { AppController } from './app.controller';
import { AppService } from './app.service';

@Module({
  imports: [
    CacheModule.registerAsync({
      imports: [
        ConfigModule.forRoot({
          validationSchema: Joi.object({
            REDIS_HOST: Joi.string().default('localhost'),
            REDIS_PORT: Joi.number().default(6379),
            REDIS_PASSWORD: Joi.string(),
          }),
        }),
      ],
      useFactory: async (configService: ConfigService) => ({
        store: redisStore,
        auth_pass: configService.get('REDIS_PASSWORD'),
        host: configService.get('REDIS_HOST'),
        port: configService.get('REDIS_PORT'),
        ttl: 0,
      }),
      inject: [ConfigService],
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

With this setting, I can use get and set as expected but I want to use other redis command such as hget and zadd. Unfortunately, I cannot find the guide anywhere.

I think there must be a way since cache-manager-redis-store package said that it just passing the configuration to the underlying node_redis package. And node-redis package can use those fancy redis commands.

Would be appreciated if you have solutions.

You can retrieve the underlying redis client by calling
cacheManager.store.getClient() even tho the interface Cache (from cache-manager) doesn't has that getClient method defined. I don't know what's the best way to type that.

The return of that will be the Redis client created by cache-manager-redis-store

I suggest nestjs-redis package. It's compatible with typescript and is dependent on ioredis package thus you get all other Redis APIs as well.
