Mach is a super fast multi-threaded bundler written in Rust that puts an emphasis on
developer experience and the runtime performance of the compiled application.

Mach is heavily inspired by the Parcel bundler

You can install Mach from npm or get the latest binary from the github releases

npm install @alshdavid/mach
npx mach version

$ mach build ./src/index.html
$ mach dev ./src/index.html #todo

import { Mach } from '@alshdavid/mach'

// Create a Mach instance
const mach = new Mach()

// Build a target
const report = await mach.build({
  projectRoot: process.cwd(),
  outFolder: 'dist',
  entries: ['src/index.js']
})

Mach comes preconfigured with sensible defaults and does not need configuration. Mach ships with built-in support for the most common source files in web development.

• TypeScript
• JavaScript
• JSX and TSX
• CSS
• HTML
• Images (todo)

Mach supports plugins that share the ideas and API of Parcel Plugins for cases where bundling must be customized.

• Resolver partial support
• Transformer partial support
• Reporter todo
• Namer todo

Plugins can be written in:

• JavaScript in progress
• Rust (Dynamically Loaded) todo
• Wasm todo

Import the plugin API from the @alshdavid/mach npm package

import { Transformer } from '@alshdavid/mach'

Below is a build of the three-js source code multiplied 100 times and reexported from a single entry point. The benchmark was run on an M1 MacBook Pro with optimizations/minification turned off.

Mach is still under development and has lots of known opportunities for further build time improvements 🙂

The goal of Mach 1 will be a super fast production ready bundler with plugin support with some features remaining to be added (for instance - incremental bundling, or caching).

The order of these may change and some may be pushed back to Mach 2

🧩 Prerelease Shooting Star

• Incremental Bundling for Development

👀 Release Candidate X-1

• TBD

🛩️ Mach 1 - Codenamed Concorde

• TBD

The benchmark takes the three-js source code, copies it 50 times, imports the 50 copies from a single entrypoint and measures the time to build.

import * as copy_1 from './copy_1/Three.js'; window.copy_1 = copy_1;
import * as copy_2 from './copy_2/Three.js'; window.copy_2 = copy_2;
import * as copy_3 from './copy_3/Three.js'; window.copy_3 = copy_3;
// ... and so on

The hardware I am using is a desktop AMD 7950x with 16 cores and the builds are using 16 threads.

Build Time (lower is better)
