index.html
component.jsx
main.js
webpack.config.js //webpack配置文件
#在 "scripts":{}
#{}内 添加一行
"dev": "webpack-dev-server --hot",
编辑webpack.config.jsjava
var config = {

},
devServer: {
inline: true,
port: 8080
},
module: {
loaders: [{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015', 'stage-0', 'react']
