# Used by Some notable organizations using BullMQ:

# The gist Install: ``` $ yarn add bullmq ``` Add jobs to the queue: ```ts import { Queue } from 'bullmq'; const queue = new Queue('Paint'); queue.add('cars', { color: 'blue' }); ``` Process the jobs in your workers: ```ts 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: ```ts 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); }, ); ``` This is just scratching the surface, check all the features and more in the official documentation # Feature Comparison Since there are a few job queue solutions, here is a table comparing them: | Feature | [BullMQ-Pro](https://bullmq.io/#bullmq-pro) | [BullMQ](https://bullmq.io) | Bull | Kue | Bee | Agenda | | :------------------------ | :-------------: | :-------------: | :-------------: | :---: | -------- | ------ | | Backend | redis | redis | redis | redis | redis | mongo | | Observables | ✓ | | | | | | | Group Rate Limit | ✓ | | | | | | | Group Support | ✓ | | | | | | | Batches Support | ✓ | | | | | | | Parent/Child Dependencies | ✓ | ✓ | | | | | | Priorities | ✓ | ✓ | ✓ | ✓ | | ✓ | | Concurrency | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | Delayed jobs | ✓ | ✓ | ✓ | ✓ | | ✓ | | Global events | ✓ | ✓ | ✓ | ✓ | | | | Rate Limiter | ✓ | ✓ | ✓ | | | | | Pause/Resume | ✓ | ✓ | ✓ | ✓ | | | | Sandboxed worker | ✓ | ✓ | ✓ | | | | | Repeatable jobs | ✓ | ✓ | ✓ | | | ✓ | | Atomic ops | ✓ | ✓ | ✓ | | ✓ | | | Persistence | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | | UI | ✓ | ✓ | ✓ | ✓ | | ✓ | | Optimized for | Jobs / Messages | Jobs / Messages | Jobs / Messages | Jobs | Messages | Jobs | ## Contributing Fork the repo, make some changes, submit a pull-request!
