修改文件后自动打包配置（监听源代码变动打包）第一种方法： package.json文件配置scripts "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "bundle": "webpack", "watch": "webpack --watch" // 监听源代码变动，自动打包 }, 第二种方法：通过webpack的devServer实现监听打包，安装webpack-dev-server // webpack.config.js中的配置 devServer: { contentBase: './dist', // 定义服务器启动服务的位置 open: true , // 启动webpack devServer的时候自动打开浏览器 proxy: { // 用于跨域配置 }, port: 8089, // 定义服务的端口号 } package.json中的配置 "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "bundle": "webpack", "server": "webpack-dev-server" // webpack-dev-server启动本地服务 }, 来源： CSDN 作者：

So // my_app.js require('./my_app

四、配置webpack-dev-server （1）理解为什么要使用 webpack-dev-server 在上面一篇文章中，我们已经可以通过webpack去打包整个项目了，但是每次写完代码，都需要手动运行一下webpack执行打包，才能看到修改后的效果，这对于我们前端开发来说是十分不方便的。还有一点就是如果我们想发送一个ajax请求，那么必须要使用http协议，而直接打开本地文件使用的则是file协议。因此，我们可以使用webpack自带的devServer来在前端开启一个小型服务器，这个服务器可以监听我们的文件改动然后自动刷新页面，可以帮助我们实现ajax请求的发送。我们在第一篇文章的开头就已经安装好了 webpack-dev-server 因此我们可以直接进入webpack.config.js去开启他！（2）配置webpack-dev-server 在module.exports中增加如下配置： devServer: { open: true, // 开启服务器后是否自动打开浏览器 port: 9090, // 服务器所占端口 contentBase: path.resolve(__dirname, 'dist'), // 服务器打开本地文件的地址 hot: true, historyApiFallback: true,//找不到页面默认跳index.html },
