Promise queue with concurrency control, interval-based rate limiting, and priority scheduling for async tasks.

A zero-dependency cron job scheduler and cron-expression evaluator for JavaScript and TypeScript
node-cron
Zero-dependency cron job scheduling for Node.js with overlap prevention and distributed coordination
Bull
Redis-backed job queue for Node.js with retries, rate limiting, and scheduling
RQ
Simple Python library for queueing jobs and processing them in the background with Redis or Valkey workers
monotonic
Backport of time.monotonic() providing a clock that never goes backwards for Python 2 and pre-3.3 Python 3
Dramatiq

ember-concurrency
Cancelable, restartable async task primitives for Ember.js that replace manual promise and flag juggling with declarative concurrency control.
quick-cache
A lightweight, high-performance concurrent cache for Rust with S3-FIFO/CLOCK-Pro eviction, atomic get-or-insert coordination, and per-item weights.
p-debounce
Debounce promise-returning and async functions, sharing one resolved value across rapid calls.
