我一直在研究一个Angular 2/Webpack项目，该项目通过模板购买了WebPack开发和生产服务器。他们按照以下方式进行：
webpack.config.js：
// Look in ./config folder for webpack.dev.js
switch (process.env.NODE_ENV) {
case 'prod':
case 'production':
module.exports = require('./config/webpack.prod')({env: 'production'});
break;
case 'dev':
case 'development':
default:
module.exports = require('./config/webpack.dev')({env: 'development'});
}
webpack.common.js：
const webpack = require('webpack');
const helpers = require('./helpers');

对不起，如果是tl; dr。我是WebPack的新手，我希望能够通过我创建的另一台Express Server为我的Angular应用程序提供服务，该应用程序也可以为我的REST API提供服务。我本来将WebPack Production Server和我的Express Server在单独的环境中，但我想看看是否可以，如果是这样。
所以有两种方法
- 在一个端口上运行Express，另一个端口（WebPack）在另一个端口上...通常在浏览器的两个选项卡中（如果您想查看API）
- 使用WebPack代理Express Server，因此您可以在同一端口上"运行"。
方法＃2的设置更为复杂，但要点是：
webpack.config.js var config = {
// webpack stuff here ...
//dev server configuration
devServer: {
// ...
// every request made to 'locahost:8080/api/xxxx' will be proxyfied to 'http://localhost:7000/api/xxxx'
proxy: {
"/api/*": {
target: "http://localhost:7000",
secure: false,
rewrite: function(req, options) {
//you can handle rewrite here if you need to
}
},
}
},
//
};
module.exports = config;
