QueueEvents不使用Heroku触发BullMQ

Question

我试图在NodeJS中使用BullMQ实现队列，但在使用远程Redis (Heroku或Redis )时，我在生产中遇到了一些问题。

在本地，一切都运行良好，但当我尝试使用REDIS_URL时，会创建一个作业，但事件不起作用。

以下是代码：

// test_job.js
import { Queue, Worker, QueueEvents } from "bullmq";
import IORedis from "ioredis";

import Dotenv from "dotenv";
Dotenv.config();

// Good
const connection = new IORedis(process.env.REDIS_URL || 6379);

// Good
const queue = new Queue("Paint", { connection });

// Good
const worker = new Worker(
  "Paint",
  async job => {
    if (job.name === "cars") {
      console.log(job.data.color);
    }
  },
  { connection }
);

/**
 * BUG HERE: Events work in local but not when using a remote Redis (REDIS_URL)
 */
const queueEvents = new QueueEvents("Paint");
queueEvents.on("completed", jobId => {
  console.log("done painting");
});

queue.add("cars", { color: "blue" });

Answer 1

const queueEvents = new QueueEvents("Paint", { connection: connection.duplicate() });
