Rspack Has a Free Rust-Based Bundler Compatible With the Webpack Ecosystem

Rspack is a high-performance JavaScript bundler written in Rust. Webpack-compatible but 5-10x faster.

What You Get for Free

• Webpack compatible — existing loaders and plugins
• 5-10x faster — Rust compilation
• HMR — fast hot module replacement
• Tree shaking — dead code elimination
• Code splitting — dynamic imports
• CSS built-in — no extra loaders

Config (same as webpack)

module.exports = {
  entry: './src/index.js',
  output: { filename: 'bundle.js' },
  module: {
    rules: [
      { test: /\.css$/, type: 'css' },
      { test: /\.tsx?$/, use: 'builtin:swc-loader' },
    ],
  },
};
