The gist

Install:

$ yarn add bullmq

Add jobs to the queue:

import { Queue } from 'bullmq';

const queue = new Queue('Paint');

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

Process the jobs in your workers:

import { Worker } from 'bullmq';

const worker = new Worker('Paint', async job => {
if (job.name === 'cars') {
await paintCar(job.data.color);
}
});

Listen to jobs for completion:

import { QueueEvents } from 'bullmq';

const queueEvents = new QueueEvents('Paint');

queueEvents.on('completed', ({ jobId }) => {
console.log('done painting');
});

queueEvents.on(
'failed',
({ jobId, failedReason }: { jobId: string; failedReason: string }) => {
console.error('error painting', failedReason);
},
);
