配置快递服务器为我的Webpack生产站点提供服务

Question

我一直在通过模板购买的Angular 2 / Webpack项目，该模板已经具有Webpack开发和生产服务器。 他们如下：

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');

抱歉，如果是TL; DR。 我对Webpack相当陌生，我希望能够通过我正在创建的另一个Express服务器为我的Angular应用程序提供服务，该服务器也为我的REST API提供服务。 我本来打算在单独的环境中使用webpack生产服务器和我的快递服务器，但是我想首先看看这是否可行，如果可以的话。

Answer 1

所以有两种方法可以做到

1. 在一个端口上运行Express，在另一个端口上运行前端（Webpack）...通常在浏览器的两个选项卡中（如果要查看api）
2. 使用webpack代理快速服务器，以便您可以在同一端口上“运行”两者。

方法2的设置较为复杂，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;
