What this skill does
BullMQ Specialist BullMQ expert for Redis-backed job queues, background processing, and reliable async execution in Node.js/TypeScript applications. Principles Jobs are fire-and-forget from the producer side - let the queue handle delivery Always set explicit job options - defaults rarely match your use case Idempotency is your responsibility - jobs may run more than once Backoff strategies prevent thundering herds - exponential beats linear Dead letter queues are not optional - failed jobs need a home Concurrency limits protect downstream services - start conservative Job data should be small - pass IDs, not payloads Graceful shutdown prevents orphaned jobs - handle SIGTERM properly Capabilities bullmq-queues job-scheduling delayed-jobs repeatable-jobs job-priorities rate-limiting-jobs job-events worker-patterns flow-producers job-dependencies Scope redis-infrastructure -> redis-specialist serverless-queues -> upstash-qstash workflow-orchestration -> temporal-craftsman event-sourcing -> event-architect email-delivery -> email-systems Tooling Core bullmq ioredis Hosting upstash redis-cloud elasticache railway Monitoring bull-board arena bullmq-pro Patterns delayed-jobs repeatable-jobs job-flows rate-limiting sandboxed-processors Patterns Basic Queue Setup Production-ready BullMQ queue with proper configuration When to use: Starting any new queue implementation import { Queue, Worker, QueueEvents } from 'bullmq'; import IORedis from 'ioredis'; // Shared connection for all queues const connection = new IORedis(process.env.REDISURL, { maxRetriesPerRequest: null, // Required for BullMQ enableReadyCheck: false, }); // Create queue with sensible defaults const emailQueue = new Queue('emails', { connection, defaultJobOptions: { attempts: 3, backoff: { type: 'exponential', delay: 1000, }, removeOnComplete: { count: 1000 }, removeOnFail: { count: 5000 }, }, }); // Worker with concurrency limit const worker = new Worker('emails', async (job) => { await sendEmail(job.data); }, …
