搭建es6开发环境

1、安装 babel-core、babel-loader、babel-preset-es2015

2、配置webpack.config.js

module.exports = {
    entry:'./index.js',
    output:{
        path:__dirname,
        filename:'bundle.js',
    },
    module:{
        loaders: [{
            test: /\.js$/,
            loaders: ['babel-loader?presets[]=es2015'],
            exclude: /node_modules/
        }]
    },
    watch:ture

}

3、执行命令webpack即可，把es6转换成普通js语法
