Example

const broker = new RPCRedisBroker({ redisClient: new Redis() });

console.log(await broker.call('testcall', 'Hello World!'));
await broker.destroy();

// responder.js
import { RPCRedisBroker } from '@discordjs/brokers';
import Redis from 'ioredis';

const broker = new RPCRedisBroker({ redisClient: new Redis() });
broker.on('testcall', ({ data, ack, reply }) => {
	console.log('responder', data);
	void ack();
	void reply(`Echo: ${data}`);
});

await broker.subscribe('responders', ['testcall']);
