# 🚀 Sponsors 🚀
Dragonfly is a new Redis™ drop-in replacement that is fully compatible with BullMQ and brings some important advantages over Redis™ such as massive
better performance by utilizing all CPU cores available and faster and more memory efficient data structures. Read more here on how to use it with BullMQ.
# 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
