pkg-bundler

Zero-config rollup bundler for npm packages built with babel

npm i -D pkg-bundler

Add a .babelrc file for your package.

{
  presets: [
    [ 'env', { modules: false } ],
    'react'
  ]
}

Add a main and optional module field to your package.json

"main": "dist/index.cjs.js",
"module": "dist/index.es.js",

Add a prepare script to your package.json

"scripts": {
  "prepare": "pkg-bundler src/index.js"
}

When publishing your package, pkg-bundler will use Rollup to create the dist bundles

Motivation

Setting up similar build configs for multiple packages is a lot of overhead. This is meant to reduce the amount of custom config added to any npm package. This is a sort of react-scripts-like package for publishing packages.
