Node Redis Support

[apedroferreira]

Does this library still support https://github.com/redis/node-redis? Doesn't seem to be working for v4 of node-redis.

I want to know this as well

I would love to get an example, since I have problems passing a valid RedisClient to publisher / subscriber prop. MAybe somebody can help me here out. I try to get it setup with NestJS

import { ConfigModule, ConfigService } from '@nestjs/config';
import { RedisPubSub } from 'graphql-redis-subscriptions';
import * as Redis from 'redis';

export const PUB_SUB = 'PUB_SUB';

@Global()
@Module({
  imports: [ConfigModule],
  providers: [
    {
      provide: 'PUB_SUB',
      useFactory: (configService: ConfigService) => {
        return new RedisPubSub({
          publisher: Redis,
          subscriber: Redis,
        });
      },
      inject: [ConfigService],
    },
  ],
  exports: [PUB_SUB],
})
export class PubSubModule {}

I know I also have to pass host and port but I'm not sure how to pass the correct Class...

UPDATE: I managed it, please see as follows - Does anyone have concerns that it is not ok?

import { Global, Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { RedisPubSub } from 'graphql-redis-subscriptions';
import * as Redis from 'redis';

export const PUB_SUB = 'PUB_SUB';

@Global()
@Module({
  imports: [ConfigModule],
  providers: [
    {
      provide: 'PUB_SUB',
      useFactory: async (configService: ConfigService) => {
        const client = await Redis.createClient({
          url:
            configService.get<string>('NODE_ENV') === 'production'
              ? 'redis://redis:6379'
              : 'redis://localhost:6379',
        }).connect();
        return new RedisPubSub({
          publisher: client as any,
          subscriber: client as any,
          messageEventName: 'message_buffer',
          pmessageEventName: 'pmessage_buffer',
        });
      },
      inject: [ConfigService],
    },
  ],
  exports: [PUB_SUB],
})
export class PubSubModule {}
