✨ Key Features

⚡ Extreme Performance: Core bundling logic implemented in Rust via NAPI-RS.
????️ Turbopack Powered: Built on top of the same engine that powers Next.js Turbopack.
???? Webpack Compatibility: Support for consuming webpack.config.js to simplify migration from Webpack.
???? Modern Web Support: Native support for TypeScript, JSX, CSS Modules, Less, Sass, and more.
???? Extensible Architecture: Support for custom loaders, plugins, and flexible configuration.
???? Fast HMR: Instant updates during development with optimized Hot Module Replacement.

✨ Supported Features

@utoo/pack aims for high compatibility with the Webpack ecosystem while providing superior performance.

Entry: Supports name, import, and filename templates.
Module Rules: Support for most mainstream Webpack loaders via loader-runner.
Resolve: Full support for alias and extensions.
Styles: Built-in support for Less, Sass, PostCSS, CSS Modules, and LightningCSS.
Optimization: Minification, Tree Shaking, Module Concatenation, and more.
Frameworks: Optimized for React (including styled-jsx, styled-components).
Tools: Integrated Bundle Analyzer and Tracing Logs.

[!TIP] For a detailed status of all features, see the Features List.

???? Installation

ut install @utoo/pack --save-dev

???? Quick Start

Programmatic API

You can use @utoo/pack directly in your Node.js scripts:

const { build, dev } = require('@utoo/pack');

// Production build
async function runBuild() {
  await build({
    config: {
      entry: [
        {
          import: "./src/index.ts",
          html: {
            template: "./index.html"
          }
        }
      ],
      output: {
        path: "./dist",
        filename: "[name].[contenthash:8].js",
        chunkFilename: "[name].[contenthash:8].js",
        clean: true
      },
      sourceMaps: true
    }
  });
}

// Development mode with HMR
async function startDev() {
  const server = await dev({
    config: {
      entry: [
        {
          import: "./src/index.ts",
          html: {
            template: "./index.html"
          }
        }
      ],
      output: {
        path: "./dist",
        filename: "[name].[contenthash:8].js",
        chunkFilename: "[name].[contenthash:8].js",
        clean: true
      },
      sourceMaps: true
    }
  });
}

???? Webpack Compatibility Mode

@utoo/pack provides a partial compatibility layer for Webpack.

const { build } = require('@utoo/pack');
const webpackConfig = require('./webpack.config.js');

async function run() {
  await build({ ...webpackConfig, webpackMode: true });
}

[!NOTE] Not all Webpack features and plugins are supported. Check the Features List for details on supported configuration options.

⚙️ Configuration

The bundler can be configured via a utoopack.json or through the programmatic API. Key configuration areas include:

entry: Define your application entry points.
define: Build-time variable replacement.
externals: Exclude specific dependencies from the bundle.
mode: development or production.

For a full list of options, see the Configuration Schema.

????️ Development

Prerequisites

Rust: Nightly toolchain (see rust-toolchain.toml).
