The **sass-css-stream** package provides a tiny Node.js wrapper that turns a Sass file into a CSS stream using node‑sass. It exports a function `sassCssStream(file, [opts])` that returns a through‑stream, allowing Sass content to be piped in and compiled CSS to be piped out—ideal for build pipelines such as Parcelify or Cartero. It’s aimed at developers who need a simple, streaming Sass‑to‑CSS transform in their Node build scripts.
