webpack modules output

commonjs_webpack_output.js

// es6 modules 打包结果大体一样，细节不同

//  app.js(entry)
var c = require('./c')
console.log(c)
module.exports = {
    a: '我是a'
}

// c.js

let c1 = 'c1'
let c2 = 'c2'
module.exports = {
	c1,
	c2,
}

// 打包结果（提取了 factory 出来）：


(function webpackUniversalModuleDefinition(root, factory) {
	if(typeof exports === 'object' && typeof module === 'object')
		module.exports = factory();
	else if(typeof define === 'function' && define.amd)
		define([], factory);
	else if(typeof exports === 'object')
		exports["app"] = factory();
	else
		root["app"] = factory();
})(typeof self !== 'undefined' ? self : this, factory);
