This is default configuration for rollup that compile javascript libraries.
It parse ECMAScript 6 javascript syntax using Babel env preset. Supported browsers are defined from package.json of compiled library. Default configuration can also handle Flow Type syntax.
All files are bundled separately. It allowed to create smaller files with compilers that does not have tree shaking like webpack.
To the destination folder are copied .js.flow so the library can be use with Flow Types.
First, install this package:
npm install @socifi/rollup-config --save-dev
Then create your rollup.config.js file:
import getConfig from 'ui-rollup-config';
import path from 'path';
import packageJson from './package.json';
export default getConfig(packageJson, path.resolve(__dirname, 'src'), {
custom: 'settings',
});
