Package Exports

oxc-minify
oxc-minify/browser.js
oxc-minify/index.js
oxc-minify/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (oxc-minify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Oxc Minify

This is alpha software and may yield incorrect results, feel free to submit a bug report.

Performance and Compression Size

See minification-benchmarks for details.

The current version already outperforms esbuild, but it still lacks a few key minification techniques such as constant inlining and dead code removal, which we plan to implement next.

Caveats

To maximize performance, oxc-minify assumes the input code is semantically correct. It uses oxc-parser's fast mode to parse the input code, which does not check for semantic errors related to symbols and scopes.

API

import { minify } from 'oxc-minify';

const filename = 'test.js';
const code = "const x = 'a' + 'b'; console.log(x);";
const options = {
  compress: {
    target: 'esnext',
  },
  mangle: {
    toplevel: false,
  },
  codegen: {
    removeWhitespace: true,
  },
  sourcemap: true,
};
const result = minify(filename, code, options);

console.log(result.code);
console.log(result.map);

Assumptions

oxc-minify makes some assumptions about the source code.
