streaming-cache

A Node.js library that caches and replays streams using an LRU cache, enabling immediate delivery of streaming data even while the source stream is still being written. Current stable version is 0.5.5, which is likely the last release (no updates since 2019). It focuses on low-latency reuse of slow streams like S3 downloads or database queries, using a fixed-size LRU cache from the lru-cache package. Its key differentiator is the ability to replay unfinished streams, unlike caching complete files.
