From node:zlib

node:zlib has gzip, zlib, raw deflate, brotli, and since Node.js 22.15, experimental zstd. comprs adds LZ4, a browser build, Web Streams, and the same API in Node.js, Deno, Bun and browsers. Its brotli is libbrotli, as in node:zlib, and it writes the same bytes at the same quality and window when Node.js bundles the same libbrotli release.

const compressed = compressSync(data, { format: 'gzip', level: 9 });
const restored = decompressSync(compressed, { format: 'gzip' });

Brotli quality. node:zlib compresses brotli at quality 11 by default; comprs at 6, which is much faster. Pass level: 11 for the output of node:zlib.
Limits. node:zlib decompresses up to buffer.kMaxLength by default; comprs stops at 256 MiB unless you raise maxOutputSize, so that a small malicious input cannot exhaust memory.
Strictness. comprs rejects truncated and empty input, and data after the end of the compressed stream (see Errors and limits).
Threads. The async functions and the streams run on the libuv thread pool, as those of node:zlib do.
Streams. @derodero24/comprs/node has a stream.Transform factory for each format, such as createGzipCompressTransform(), for stream.pipeline().
