PortQueue is a database-backed job queue for Node.js — no broker required. If your app already runs a relational database, you already have everything you need for a reliable queue. PortQueue treats that database as the single source of truth and works across PostgreSQL, Oracle, PGLite, and SQLite from one API.

Adding a queue shouldn't mean adding a broker. If you already run PostgreSQL (or SQLite, or Oracle), you already have durable storage, transactions, and — with SKIP LOCKED and LISTEN/NOTIFY — everything a robust queue needs.

An honest look at where each of these shines — and where PortQueue's multi-driver, distributed-by-design, transactional approach matters.

You write an order row, then enqueue its fulfillment job. What happens if the process dies between the two? Or the transaction rolls back after the job was queued? You get a job referencing data that doesn't exist — the dual-write bug.
