Reducing backend latency with BullMQ job queues in Node.js

Short summary

Synchronous backend APIs can force users to wait 7+ seconds while emails, image processing, and notifications complete sequentially. The fix is to save core data, queue heavy work in Redis-backed BullMQ, and return a response in ~50ms while workers process jobs asynchronously with automatic retries and exponential backoff. The article includes concrete Node.js code for setting up queues, workers, and job options.

• •Synchronous request handling causes multi-second user waits for tasks like emails and notifications
• •BullMQ + Redis lets you queue jobs and return responses in ~50ms
• •Includes working Node.js code with retry logic, exponential backoff, and job lifecycle options
