Build a Job Queue with Redis
Move slow work off the request/response cycle with a Redis-backed job queue — producers, workers, automatic retries with backoff, and multi-step job flows using BullMQ.
Prerequisites: REST API Fundamentals with Node.js; Redis running locally.
Targeted versions: BullMQ 5.7x; ioredis as the Redis client; verified against docs.bullmq.io and the taskforcesh/bullmq GitHub repo, mid-2026.
Some work — sending an email, generating a report, processing an upload — shouldn't block an HTTP response. You'll build a producer that enqueues jobs from your API and a worker that processes them independently, with automatic retries when a job fails, backed entirely by Redis so it works the same whether your worker runs in-process or on a completely separate machine.
