The zero-configuration bundler for tiny modules, powered by Rollup.
- Bundles your library using nothing but a
package.json - Support for ESnext & async/await (via Bublé & Nodent)
- Supports multiple entry modules (
cli.js+index.js, etc) - Creates multiple output formats for each entry (CJS, UMD & ESM)
- Built-in Uglify compression & gzipped bundle size tracking
npm i -D microbundle
... then add the scripts to your package.json:
{
"scripts": {
"build": "microbundle",
"dev": "microbundle watch"
}
}Microbundle includes two commands - build (the default) and watch. Neither require any options, but you can tailor things to suit your needs a bit if you like.
By default, microbundle will infer the location of your source entry file
(the root module in your program) from the module field in your package.json. It will infer the output directory and filename(s) from the main field.
Just like microbundle build, but watches your source files and rebuilds on any change.
microbundle [entries..]
