`async-transforms` provides drop‑in stream.Transform utilities for Node that let you write asynchronous handlers (with async/await) and run them in parallel, optionally preserving order or limiting concurrency. It’s aimed at build‑tool authors and Gulp‑style pipelines that need fast, easy‑to‑write async processing (e.g., compiling Less, minifying files), and it also ships a lightweight worker‑pool helper for CPU‑bound tasks.
