@youneed/server-middleware-compression

gzip/brotli the response when the client accepts it and the body is worth compressing. It buffers the response (intercepting res.write/res.end), so it suits typical JSON/text/HTML payloads rather than very large streams.

import { Application } from "@youneed/server";
import { compression } from "@youneed/server-middleware-compression";

Application()
  .use(compression({ threshold: 1024 }))
  .listen(3000, () => {});

| option | default | meaning | | --- | --- | --- | | threshold | 1024 | minimum body size (bytes) before compressing | | brotli | true | prefer brotli when the client supports it |

Sets Content-Encoding, recomputes Content-Length, and appends Accept-Encoding to Vary. Bodies below threshold, already-encoded responses, and non-compressible content types are passed through untouched.
