Queue

Construct a queue and the full producer/admin API.

Sub-pages

The Queue API is split across several pages for readability:

Job Management — fetch jobs, await results, stream partials, cancel
Queue & Stats — statistics, dead letters, pause/resume, cleanup
Workers & Hooks — run workers, list workers, event hooks, middleware
Resources & Locking — resources, enqueue gates, distributed locks, periodic tasks
Events & Logs — webhooks, task logs
Pub/Sub — topic subscriptions, fan-out publish

import { Queue } from "@byteveda/flexiq";

const queue = new Queue(options);

Constructor options

Option	Type	Description
`dbPath`	`string`	SQLite file path (default backend).
`backend`	`"sqlite" \| "postgres" \| "redis"`	Storage backend.
`dsn`	`string`	Connection string for postgres/redis.
`poolSize`	`number`	Connection pool size (sqlite/postgres).
`schema`	`string`	Postgres schema (default `flexiq`).
`prefix`	`string`	Redis key prefix.
`namespace`	`string`	Namespace applied to enqueued jobs + the worker scheduler.
`serializer`	`Serializer`	Arg/result serializer (default `JsonSerializer`).
`codec`	`PayloadCodec \| PayloadCodec[]`	Global codec chain wrapping the serializer — covers every payload and result. See Serializers.
`codecs`	`Record<string, PayloadCodec>`	Named codec registry for per-task `codecs` (payload only).

Method	Description
`task(name, fn, config?)`	Register a task. See Task.
`configureQueue(name, config)`	Set per-queue rate limit / concurrency.
`enqueue(task, args?, options?)`	Enqueue a job → job id. Throws if a gate rejects or skips.
`tryEnqueue(task, args?, options?)`	Enqueue a job → job id, or `null` when a gate skipped it. A gate that rejects still throws.
`enqueueMany(task, jobs[])`	Batch-enqueue `{ args?, options? }[]` → job ids in input order, `uniqueKey` entries deduped.
