记一个简单的webpack.config.js

module.exports = {
	entry: './basic/app.js',
	output: {
		path: './assets/',
		filename: '[name].bundle.js'
	},
	module: {
		loaders: [{
			//babel-loader加载器，将es6转es5
			test: /\.js$/,
			loader: 'babel'
		}, {
			//style-loader,css-loader加载器，当调用bundle.js
			//时动态生成sytle标签，插入html中的head
			test: /\.css$/,
			loader: 'style!css'
		}]
	}
};

package.json 中的安装依赖

  "devDependencies": {
    "babel-loader": "^6.2.5",
    "babel-preset-es2015": "^6.16.0",
    "css-loader": "^0.25.0",
    "style-loader": "^0.13.1",
    "webpack": "^1.13.2"
  }

安装过程的坑

cnpm install webpack --save-dev
cnpm install babel-loader --save-dev
cnpm install css-loader --save-dev
cnpm install style-loader --save-dev

运行webpack 出现错误，后来查了babel-loader需要安装babel-preset-es2015包依赖

cnpm install babel-preset-es2015 --save-dev
