旧代码存档：用 Rollup 打包 ES6 模块

build-es.js

'use strict'

var gulp = require('gulp')


gulp.task('mobile/build-es', function () {
	var path = require('path')
	var glob = require('glob')

	var rollup = require('rollup').rollup
	// var commonjs = require('rollup-plugin-commonjs')
	// var nodeResolve = require('rollup-plugin-node-resolve')

	var config = require('../config')

	var entries = glob.sync('./mobile/js/*.js')

	var tasks = entries.map(function (item) {
		console.log('[Rollup] Bundling: ' + item)
		return rollup({
			entry: item,
			plugins: [
				// nodeResolve({
				// 	jsnext: true,
				// 	main: true,
				// }),
				// commonjs(),
			],
		}).then(function (bundle) {
			var dest = path.join(config.dist, 'w', path.basename(item))
			console.log('[Rollup] Bundled to: ' + dest)
			return bundle.write({
				format: 'iife',
				dest: dest,
			})
		}, function (err) {
			console.error('[Rollup] Error: ' + err.message)
		})
	})

	return Promise.all(tasks)
})
