p-queue-es5

Promise queue with concurrency control, priority, and rate limiting. Version 6.0.2 is stable and maintained. Allows limiting concurrent async operations, per-operation timeouts, interval-based rate limiting, and priority scheduling. Compatible with ES5 environments like older Node.js and some bundlers. Built as CommonJS with TypeScript declarations. No native dependencies. Lightweight alternative to bottleneck, p-limit, or async.queue.
