BullMQ

BullMQ is a fast, robust, Redis-backed job queue library for Node.js, engineered for reliable, distributed background task processing.

BullMQ is the next-generation, TypeScript-based rewrite of the popular Bull library, purpose-built for high-performance background job processing in Node.js. It leverages Redis for rock-solid persistence and horizontal scaling, ensuring zero job loss and high throughput across multiple workers and servers. The library handles complex workflows with features like delayed jobs, automatic retries, priority queuing, and explicit rate limiting. Use it to offload resource-intensive tasks: think video transcoding, bulk email campaigns, or large-scale data processing. BullMQ provides the stability and feature set—including flow producers and global events—required for modern, decoupled microservices architectures.
