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);
},
);
