p-queue
A promise queue with concurrency control for rate-limiting async operations.
What is p-queue?
p-queue is a JavaScript library that provides a promise queue with configurable concurrency control and rate limiting. It helps developers manage asynchronous operations by limiting how many tasks run simultaneously and enforcing execution rates over time intervals. This is essential for preventing resource exhaustion when interacting with APIs or performing intensive computations.
JavaScript and Node.js developers who need to manage concurrent async operations, particularly those working with rate-limited APIs, performing batch processing, or implementing task scheduling with priority control.
Developers choose p-queue for its comprehensive feature set including priority scheduling, strict rate limiting modes, abort support, and detailed monitoring capabilities. It offers more control and reliability than simpler concurrency libraries while maintaining a clean API.
