此处用到nodemon跑服务器：命令行输入：npm run serve即可，会忽略components的改变，其余时候都会自动重启服务器
不用nodemon的话，就用node server/server.js 启动服务器

在此处是用的node做后台，并且配置了webpack.config.js的信息，不然，在跑服务器前，要先输入webpack --config webpack.config.js 命令来生成bundle.js文件。
并且也用到了热加载，webpack-dev-middleware webpack-hot-middleware 在代码改变后，立马更新html页面

var express = require('express');
var path = require('path');
var config = require('../webpack.config.js');
var webpack = require('webpack');
var webpackDevMiddleware = require('webpack-dev-middleware');
var webpackHotMiddleware = require('webpack-hot-middleware');

var app = express();

var compiler = webpack(config);

app.use(webpackDevMiddleware(compiler,{noInfo: true,publicPath: config.output.publicPath}));
app.use(webpackHotMiddleware(compiler));

app.use(express.static('./dist'));

app.use('/',function (req,res) {
    res.sendFile(path.resolve('client/index.html'));
});

var port = 3000;

app.listen(port,function(error) {
  if (error) throw error;
  console.log("Express server listening on port",port);
});
