import IORedis from ioredis; // 所有队列共享同一个连接 const connection new IORedis(process.env.REDIS_URL, { maxRetriesPerRequest: null, // BullMQ 必需项 enableReadyCheck: false, }); // 带合理默认值的队列 const emailQueue new Queue(emails, { connection, defaultJobOptions: { attempts: 3, backoff: { type: exponential, delay: 1000, }, removeOnComplete: { count: 1000 }, removeOnFail: { count: 5000 }, }, }); // 带并发上限的 Worker const worker new Worker(emails, async (job) { await sendEmail(job.data); }, { connection, concurrency: 5, limiter: { max: 100, duration: 60000, // 每分钟 100 个任务 }, }); // 事件监听 worker.on(failed, (job, err) { console.error(Job ${job?.id} failed:, err); });要点解析maxRetriesPerRequest: null是 BullMQ 的硬性要求否则 Redis 连接异常会导致 Worker 停止工作对应 Validation Checks 中的 ERROR 级检查defaultJobOptions将重试次数、指数退避、完成/失败保留策略固化到队列级避免每个任务重复配置removeOnComplete: { count: 1000 }/removeOnFail: { count: 5000 }用保留最近 N 条代替无限堆积控制 Redis 内存占用limiter实现队列级速率限制concurrency控制并发两者配合既保护 Redis 又保护下游服务数据库连接池、第三方 API 限流。3.2 延迟任务与定时Repeatable任务技能用三个调用覆盖调度场景// 延迟任务24 小时后执行一次 await queue.add(reminder, { userId: 123 }, { delay: 24 * 60 * 60 * 1000, // 24 hours }); // 定时任务每天 9 点执行显式时区 await queue.add(daily-digest, { type: summary }, { repeat: { pattern: 0 9 * * *, // 每天 9am tz: America/New_York, }, }); // 移除定时任务 await queue.removeRepeatable(daily-digest, { pattern: 0 9 * * *, tz: America/New_York, });两个关键坑位在技能 Validation Checks 中单独列出Repeatable job without explicit timezoneWARNING——不指定时区会用服务器本地时间跨夏令时DST会出现漂移因此tz参数应视为必填Retry without backoff strategyWARNING——有重试但没有退避会造成惊群效应。3.3 Job Flows多步骤任务编排与依赖FlowProducer 让父任务等待所有子任务完成成为一等公民import { FlowProducer } from bullmq; const flowProducer new FlowProducer({ connection }); // 父任务等待所有子任务完成后继续 await flowProducer.add({ name: process-order, queueName: orders, data: { orderId: 123 }, children: [ { name: validate-inventory, queueName: inventory, data: { orderId: 123 }, }, { name: charge-payment, queueName: payments, data: { orderId: 123 }, }, { name: notify-warehouse, queueName: notifications, data: { orderId: 123 }, }, ], });这是技能 Capabilities 中flow-producers与job-dependencies的具体落地库存校验、扣款、仓库通知三个子任务可以并行执行且分属不同队列父任务process-order会在全部子任务成功后才被触发天然实现多阶段、有依赖、可并行的复杂流程。结合原则 7子任务数据同样只传orderId这类 ID 而非完整对象。3.4 优雅关闭部署时零任务丢失Worker 直接被杀掉会留下孤儿任务技能的关闭流程是const shutdown async () { console.log(Shutting down gracefully...); // 1. 停止接收新任务 await worker.pause(); // 2. 等待当前任务执行完成可加超时 await worker.close(); // 3. 关闭队列连接 await queue.close(); process.exit(0); }; process.on(SIGTERM, shutdown); process.on(SIGINT, shutdown);顺序上有讲究先pause()停止消费再close()等待在途任务收尾最后关闭连接。技能在 Validation Checks 中将No graceful shutdown handling标记为 WARNING——缺失时部署/重启会造成任务孤儿化。3.5 Bull Board 可视化看板需要可见性时技能推荐 bull-board 系列import { createBullBoard } from bull-board/api; import { BullMQAdapter } from bull-board/api/bullMQAdapter; import { ExpressAdapter } from bull-board/express; const serverAdapter new ExpressAdapter(); serverAdapter.setBasePath(/admin/queues); createBullBoard({ queues: [ new BullMQAdapter(emailQueue), new BullMQAdapter(orderQueue), ], serverAdapter, }); app.use(/admin/queues, serverAdapter.getRouter());挂载后即可在/admin/queues可视化查看队列状态、任务状态分布与失败详情与技能 Tooling 中的bull-board、arena对应。四、Validation Checks把经验固化为可执行检查技能最有工程价值的产出是 11 项代码检查含严重级别与告警文案可直接沉淀为 Lint 规则或 Code Review 清单检查项级别核心信息Redis 连接缺少maxRetriesPerRequestERROR缺省会导致 Redis 异常时 Worker 停摆无 stalled 事件处理器WARNINGstalled 任务提示 Worker 崩溃应监控无 failed 事件处理器WARNING失败任务应记录日志并告警无优雅关闭处理WARNING部署时任务可能被孤儿化请求处理器中 await queue.addINFO建议 fire-and-forget 以加快响应任务数据可能过大WARNING传 ID 而非完整对象控制 Redis 内存任务无超时配置INFO建议设置 timeout 防卡死有重试但无退避策略WARNING应使用指数退避防惊群定时任务未指定时区WARNING服务器本地时间会随 DST 漂移Worker 并发可能过高INFO确认下游DB 连接、API 限流能承受请求处理器阻塞入队INFO入队应异步、快速返回这些检查与第三节的代码模式一一对应可作为代码写完自检一遍的 checklist。五、协作栈与其他技能组合的实战编排技能的 Collaboration 部分定义了委托触发词与多技能工作流体现了本仓库技能组合的工程理念委托触发触发词 → 目标技能redis infrastructure|redis cluster|memory tuning→redis-specialist队列依赖 Redis 基础设施serverless queue|edge queue|no redis→upstash-qstash不想自管 Rediscomplex workflow|saga|compensation|long-running→temporal-craftsman超出简单 Job 的编排event sourcing|CQRS|event streaming→event-architectdeploy|kubernetes|scaling|infrastructure→devopsmonitor|metrics|alerting|dashboard→performance-hunter。Email Queue Stackbullmq-specialistemail-systemsredis-specialist1.
