@wasm-zoo/brotli

Unofficial WASM Zoo distribution of the upstream Google Brotli 1.2.0 CLI for browsers. This package is backed by Brotli 1.2.0, Zoo builder 0.1.0, and the reviewed browser-full Release asset.

Install

npm install @wasm-zoo/brotli

Use

import { load } from "@wasm-zoo/brotli";

const brotli = await load();
try {
  const compressed = await brotli.exec(["-q", "11", "-o", "/output.br", "/input.bin"], {
    files: [{ name: "/input.bin", data: inputBytes }],
    outputs: ["/output.br"]
  });
  console.log(compressed.files[0].data);
} finally {
  brotli.dispose();
}

The default entry imports the reviewed browser wrapper and uses static new URL(..., import.meta.url) references so modern bundlers can emit brotli-core.js, brotli-core.wasm. For manual/self-hosted deployments use @wasm-zoo/brotli/self-hosted and the Consumer API v1 baseUrl contract.

Single-threaded upstream brotli CLI in an isolated Web Worker with Emscripten MEMFS. No SharedArrayBuffer or cross-origin isolation is required. Inputs and outputs are explicitly staged in browser memory; the package preserves ordinary upstream CLI arguments rather than replacing Brotli with a JavaScript codec API.
