reactjs - Electron/React 应用程序中的热重载

Question

热重载似乎不再起作用。我不确定我的设置可以改变什么，事实上，据我所知，并且 git 日志显示，没有任何改变。

无论如何，我正在尝试重新加载 CSS 和 React .jsx 文件。

目前，我在另一个控制台选项卡中运行 npm run watch，然后运行 ​​npm run start。应用程序启动，但文件中的任何更改都不会重新加载。我的 package.json 如下所示:

{
  ...
  "main": "main.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "cross-env ENVIRONMENT=DEV electron main.js",
    "watch": "webpack-dev-server --hot --inline",
    "build": "webpack"
  },
  "dependencies": {
    "axios": "^0.15.2",
    "babel": "^6.5.2",
    "babel-loader": "^6.2.5",
    "babel-plugin-transform-class-properties": "^6.19.0",
    "babel-preset-es2015": "^6.6.0",
    "babel-preset-react": "^6.5.0",
    "babelify": "^7.2.0",
    "cross-env": "^3.1.1",
    "electron": "^1.3.4",
    "electron-prebuilt": "^1.4.2",
    "json-loader": "^0.5.4",
    "react": "^15.3.2",
    "react-dom": "^15.3.2",
    "react-router": "^2.8.1",
    "react-tap-event-plugin": "^1.0.0",
    "semantic-ui-react": "^0.56.13",
    "socket.io-client": "^1.5.0",
    "store": "^1.3.20",
    "webpack": "^1.13.3"
  },
  "devDependencies": {
    "css-loader": "^0.25.0",
    "style-loader": "^0.13.1",
    "webpack-dev-server": "^1.16.2"
  }
}

省略了一些不必要的依赖项。我的 webpack.config.js 如下所示:

var path = require("path");

module.exports = {
  entry: path.resolve(__dirname, "app/index.jsx"),
  output: {
    path: path.resolve(__dirname, "build"),
    publicPath: 'http://localhost:8080/build/',
    filename: 'app.js'
  },
  module: {
    loaders: [
        {
            test: /\.jsx?$/,
            loader: 'babel',
            exclude: /node_modules/
        },
        { 
            test: /\.css$/,
            loader: "style-loader!css-loader"
        },
        { 
            test: /\.json$/, 
            loader: "json-loader"
        }
    ]
  }    
};

在这个设置中我缺少什么来让热重载工作？

编辑:如您所见，入口点定义为index.jsx。这个文件非常简单，如下所示:

import React from 'react';
import ReactDOM from 'react-dom';
import styles from './styles.css'
import routes from './router.jsx'

ReactDOM.render(
  routes,
  document.getElementById('app')
);

每当我对此文件进行更改时，就会触发热重载。此外，对此处导入的文件(如 styles.css)的更改也会重新加载。问题是，我的所有组件显然都是导入到我的路由器中的。因此，对我的组件的任何更改都不会热重新加载。我怎样才能让它正常工作？

我在 webpack.config.js 中使用此选项:

var path = require('path');
var webpack = require('webpack');

module.exports = {
  name: 'client',
  entry: './client.js',
  output: {
    path: __dirname, filename: 'bundle.js'
  },
  module: {
    loaders: [
      { 
        test: /\.jsx?$/,         // Match both .js and .jsx files
        exclude: /node_modules/, 
        loader: "babel-loader", 
        query:
        {
          presets: ['es2015', 'react']
        }
      }
    ]
  },
  devServer: {
    historyApiFallback: true
  },
}

并进入package.json这个选项:

  "scripts": {
    "start": "npm run dev",
    "webpack": "webpack --progress --colors",
    "dev": "webpack-dev-server --devtool eval --progress --colors --inline"
  },
