Question: How can I establish a connection in BullMQ?


To establish a connection in BullMQ, you primarily need to create an instance of a queue by using the Queue class provided by the BullMQ library. This involves setting up a Redis server as BullMQ is backed by this. Here's a basic example:

const { Queue } = require('bullmq'); // You need to have redis server running const connectionOpts = { host: '', port: 6379, password: 'your_password', // If set in your Redis server }; const myQueue = new Queue('my-queue', { connection: connectionOpts }); // Now you can add jobs to the queue myQueue.add('myJob', { foo: 'bar' });

In the above code snippet,

  1. We import the Queue module from the bullmq package.
  2. We define the connectionOpts object for our Redis connection.
  3. We create a new instance of a Queue named 'my-queue' and pass the connection options to it.

After this, we've successfully connected to our Redis instance and have a BullMQ queue ready to use. You can then proceed to add jobs to the queue using the add method on the queue instance (like myQueue.add('myJob', { foo: 'bar' });).

Please make sure the Redis server is running before initiating the Queue. The host and port are the address where the Redis server is running.
