A zero-configuration bundler for tiny modules, powered by Rollup.
- Bundles your library using nothing but a
package.json - Supports multiple entry modules (
cli.js+index.js, etc) - Creates multiple output formats for each entry (CommonJS, UMD & ESM)
npm i -D microbundle
... then add it as an npm script:
{
"scripts": {
"build": "microbundle",
"dev": "microbundle watch"
}
}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.
Watches source files and rebuilds on any change.
