Bundle ES6 modules with gobble and rollup.
First, you need to have gobble installed - see the gobble readme for details. Then,
npm i -D gobble-rollupgobblefile.js
var gobble = require( 'gobble' );
module.exports = gobble( 'src' ).transform( 'rollup', {
// REQUIRED - the file to start bundling from
entry: 'app.js',
// where to write the file to. If omitted,
// will match the entry module's name
dest: 'bundle.js',
// what type of module to create - can be one of
// 'amd', 'cjs', 'es6', 'iife', 'umd'. Defaults to 'cjs'
format: 'umd',
// if generating a 'umd' module, and the entry module
// (and therefore the bundle) has exports, specify
// a global name
moduleName: 'myApp', // becomes `window.myApp`
// if generated 'amd' or 'umd', you can specify a
// moduleId which will be used by AMD loaders
moduleId: 'my-app',
// set export type explicitly - 'named', 'default' or 'none'.
// By default this will be set automatically
exports: 'default',
// disable caching, in case that's necessary for
// some reason
cache: false
