# BullMQ - Premium Message Queue for Node.js
> Fast, reliable Redis-based distributed queue for Node.js with support for multiple languages
BullMQ
The fastest, most reliable Redis-based distributed queue for Node.js. Carefully written for rock solid stability and atomicity.
## Why BullMQ?
BullMQ is a Node.js library that implements a fast and robust queue system built on top of Redis. It helps resolve many modern microservices architecture challenges with exactly-once queue semantics, horizontal scalability, and high performance.
Optimized Redis scripts and pipelining deliver maximum throughput with minimal CPU usage
Exactly-once delivery semantics with automatic recovery from process crashes
Add more workers to process jobs in parallel across multiple servers
Native support for Node.js, Python, Elixir, and PHP implementations
## Key Features
Schedule jobs for future execution or set up repeatable jobs with cron patterns
Create complex job dependencies with parent-child relationships
Control job processing rates to prevent overwhelming downstream services
Process important jobs first with flexible priority levels
Automatic retry logic with exponential backoff strategies
Built-in metrics and OpenTelemetry support for monitoring
## Quick Example
Get started with BullMQ in just a few lines of code:
```typescript Producer theme={null}
import { Queue } from 'bullmq';
const queue = new Queue('image-processing');
// Add a job to the queue
await queue.add('resize', {
imagePath: '/path/to/image.jpg',
width: 800,
height: 600
});
```
```typescript Worker theme={null}
import { Worker } from 'bullmq';
const worker = new Worker('image-processing', async job => {
if (job.name === 'resize') {
// Process the image resize job
await resizeImage(job.data);
}
});
```
