折腾：
【已解决】把ReactJS项目react-hot-boilerplate中的Webpack 1升级到Webpack 3
期间，在升级Webpack 3同时，需要去把react-hot-boilerplate之前的调试方式，从：
“webpack-dev-middleware”: “^1.6.1”, “webpack-hot-middleware”: “^2.10.0” |
react-hot-boilerplate/react-hot-boilerplate/server.js
var path = require(‘path’); var webpack = require(‘webpack’); var express = require(‘express’); var config = require(‘./webpack.config’); var app = express(); var compiler = webpack(config); app.use(require(‘webpack-dev-middleware’)(compiler, { publicPath: config.output.publicPath })); app.use(require(‘webpack-hot-middleware’)(compiler)); // app.use(express.static(‘./public’)); //Set the folder from where you serve all static files like images, css, javascripts, libraries etc app.get(‘*’, function(req, res) { res.sendFile(path.join(__dirname, ‘index.html’)); }); app.listen(3000, function(err) { if (err) { return console.error(err); } console.log(‘Listening at http://localhost:3000/’); }); |
改为直接用webpack-dev-server，这样调试起来很方便。
尤其是直接能用上HMR，而无序繁杂的配置。

之前此处是：
“react-hot-loader”: “^1.3.0”,
现在去卸载了安装最新版：

react-hot-loader/docs at master · gaearon/react-hot-loader
“react-hot-loader”: “^3.0.0-beta.7”, |
【总结】
最后用如下方式：
先去安装对应插件：
npm install webpack-dev-server –save-dev npm install –save react-hot-loader@next |
然后代码和配置：

然后在运行npm run dev（调用webpack-dev-server之前）
先去：
npm run build（运行webpack -p去生成此处的
index.js
vendor.bundle.js
到对应的build文件夹中
然后再去运行：
npm run dev
即可启动：
webpack-dev-server
去编译和加载模块和HMR了。
然后去（Chrome）浏览器打开：
即可正常调试。
然后貌似可以基本工作了：
至少：
（1）webpack-dev-server可以运行了，貌似没啥大问题
（2）HMR基本工作了，修改代码后，可以自动加载更新了
效果：
只不过，还有点其他小问题：
HMR虽然可以工作，但是修改代码后，结果却是更新所有页面的代码，而不是只更新单个模块。
暂时先不去深究。等写了很多页面之后，还是全部刷新，而不是只刷新模块等话，再说。
