如何在Heroku上运行React SSR和客户端

Question

我试图弄清楚如何在部署到Heroku的同时运行我的React SSR和构建客户端。我想我需要更改.package.json文件。开发人员运行npm run dev。

"scripts": {
    "dev:build-server": "NODE_ENV=development webpack --config webpack.server.js --mode=development -w",
    "dev:start": "nodemon ./server-build/index.js",
    "dev": "npm-run-all --parallel build dev:*",
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-scripts eject",
    "heroku-postbuild": "npm run build"
  },

我的webpack.server.js文件是这样的：

const path = require('path');
const nodeExternals = require('webpack-node-externals');

module.exports = {
  entry: './server/index.js',

  target: 'node',

  externals: [nodeExternals()],

  output: {
    path: path.resolve('server-build'),
    filename: 'index.js'
  },

  module: {
    rules: [
      {
        test: /\.js$/,
        use: 'babel-loader'
      }
    ]
  }
};
