A unified javascript build system

📦 Optimized bundler

Robust rollup based bundler that supports typescript and generates commonjs and module formats + type declarations.

📁 Bundleless build

Integration with mkdist for generating bundleless dists with file-to-file transpilation.

✨ Passive watcher

Stub dist once using jiti and you can try and link your project without needing to watch and rebuild during development.

✍ Untype Generator

Integration with untyped.

✔️ Build Validator

Automatically check for potential missing and unused dependencies. Also you can check output size and exports quickly in CLI output.

Usage

Create src/index.ts and build.config.ts:

export default {
  entries: [
    './src/index'
  ]
}

Configuration

You can either use unbuild key in package.json or build.config.{js,ts,json} to specify configuration.

See options here.

Example:

import { defineBuildConfig } from 'unbuild'

export default defineBuildConfig({
    // If entries is not provided, will be automatically inferred from package.json 
    entries: [
        // default
        './src/index',
        // mkdist builder transpiles file-to-file keeping original sources structure
        {
            builder: 'mkdist',
            input: './src/package/components/',
            outDir: './build/components'
        },
    ],

    // Change outDir, default is 'dist'
    outDir: 'build',

    // Generates .d.ts declaration file
    declaration: true,
})
