p-queue is a TypeScript promise queue library for Node.js that provides concurrency control for async or sync operations. It lets you rate-limit tasks with configurable concurrency, timeouts, priorities, and pause/resume behavior.

Use cases

• rate-limit requests to a REST API
• run async tasks with a concurrency limit
• throttle CPU or memory intensive operations
• queue background jobs in a Node.js app
• prioritize certain async tasks over others
• add timeouts to queued async operations

When to choose

• you need in-process concurrency control for promises in Node.js
• you want a lightweight rate limiter for API calls or batch tasks
• you need priority queues or per-task timeouts for async work

When to avoid

• you need a persistent or distributed job queue across servers (use a Redis-backed queue like BullMQ)
• your project uses CommonJS since the package is ESM-only
• you need features beyond what the feature-complete library offers
