Microbundle

A zero-configuration bundler for tiny modules, powered by Rollup.

• Reads all the necessary information from your package.json
• Supports multiple entry modules (cli.js + index.js, etc)
• Creates multiple output formats for each entry (CommonJS, UMD & ESM).

Installation

npm i -D microbundle

... then add it as an npm script:

{
	"scripts": {
		"build": "microbundle",
		"dev": "microbundle watch"
	}
}
