React Hot Reload无法与Webpack 4一起使用 [英] React hot reload not working with webpack 4

问题描述

反应热重装无法正常工作. 在webpack条目中，我有以下代码.

React hot reload is not working. In webpack entry, I have following code.

entry: {
        home: [
            'webpack-dev-server/client?http://0.0.0.0:8000', 
            'webpack/hot/dev-server', // add "only-dev-server" prevents reload on syntax errors
            path.join(__dirname, 'app/home-styles.js')
        ],
        main: [
            'babel-polyfill',
            path.join(__dirname, 'app/styles.js'),
            path.join(__dirname, 'app/vendor.js'),
            path.join(__dirname, 'app/index.js')
        ]
    },

在开发服务器中，我的名字是hot = true;

and in dev-server I have hot = true;

并且我有以下代码用于将提供程序封装为热

and i have below code for wrapping Provider in hot

class Root extends Component {
    render() {
        const { store, history } = this.props;
        return (
            <Provider store={store}>
                <Router history={history} routes={routes(store)}/>
            </Provider>
        );
    }
}

export default hot(module)(Root);

这是在控制台中得到的结果，但是当进行一些更改时什么也没有发生.因此，基本上看起来好像热装正在工作，但是..没有任何变化反映出来.我在这里想念什么. ?

This is result in console, but nothing happens when there is some change. So basically it appears as if hot reload is working but.. no changes reflects. What am I missing here. ?

我正在使用react 16.2.*和react-hot-loader @ 4.0.*一个webpack @ 4.5.*

I am using react 16.2.* and react-hot-loader @4.0.* an webpack @4.5.*

推荐答案

尝试像这样更新您的开发服务器配置

try updating your dev server config like so

const devServerOptions = {
    contentBase: './dist',
    hot: true,
    host: 'beta.whenidev.net',
    https: true,
  };
// if you're adding a dev server entry do it like this
  WebpackDevServer.addDevServerEntrypoints(config, devServerOptions);
