From pako

pako is a JavaScript port of zlib. comprs reads and writes the same three formats, gzip, zlib and raw deflate, with native code in Node.js, Deno and Bun and WebAssembly in browsers, and adds zstd, brotli and LZ4.

import pako from 'pako';
const compressed = pako.gzip(data, { level: 9 });
const restored = pako.ungzip(compressed);
import { compressSync, decompressSync } from '@derodero24/comprs/next';
const compressed = compressSync(data, { format: 'gzip', level: 9 });
const restored = decompressSync(compressed, { format: 'gzip' });

zlib and raw deflate. pako’s deflate() writes zlib data, as 'deflate' of the unified API does. The deflateCompress() function of the package root writes raw deflate, like pako’s deflateRaw().
Results. The unified API returns a Uint8Array, as pako does. The functions of the package root return a Node.js Buffer in the native addon, which is a Uint8Array too.
Strings. comprs takes and returns bytes only: encode a string with new TextEncoder().encode(text), and decode the result with new TextDecoder().decode(bytes).
Errors. comprs throws an Error with a code for invalid, truncated and oversized data, and stops at a decompression limit of 256 MiB by default.
Dictionaries. pako’s deflate dictionaries have no counterpart in comprs, which has dictionaries for zstd and brotli instead.
