async-cache-queue

A lightweight asynchronous task queue with built-in caching, timeout, throttle, and background prefetching. Version 0.2.8 is stable as of 2025, with infrequent releases. It differentiates from similar libraries (e.g., p-limit, memoizee) by combining queue, concurrency control, positive/negative caching, TTL-based expiration, background refresh, and optional external storage support in a single small package (~2KB gzipped). Ships TypeScript declarations and supports both CJS and ESM.
