要启用Webpack的热更新功能,你需要安装和配置两个插件:webpack-dev-server和webpack-hot-middleware。首先,你需要在webpack配置文件中添加devServer选项,指定一些配置参数,比如设置热更新的入口文件和输出路径等。然后,你需要在你的应用程序中引入webpack-dev-server/client和webpack/hot/dev-server这两个文件。这两个文件负责与Webpack Dev Server建立websocket连接,并且监听文件的变化。当文件发生变化时,Webpack Dev Server会通过websocket通知客户端进行热更新。所以,通过这两个插件的配合,你就可以实现Webpack的热更新功能了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
