Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

Save Automatically?

If active, Pens will autosave every 30 seconds after being saved once.

Auto-Updating Preview

              class Plugin {
  apply(compiler) {
    compiler.plugin('emit', function (compilation, callback) {
      // compilation.chunks 存放所有代码块,是一个数组
      compilation.chunks.forEach(function (chunk) {
        // chunk 代表一个代码块
        // 代码块由多个模块组成,通过 chunk.forEachModule 能读取组成代码块的每个模块
        chunk.forEachModule(function (module) {
          // module 代表一个模块
          // module.fileDependencies 存放当前模块的所有依赖的文件路径,是一个数组
          module.fileDependencies.forEach(function (filepath) {

        // Webpack 会根据 Chunk 去生成输出的文件资源,每个 Chunk 都对应一个及其以上的输出文件
        // 例如在 Chunk 中包含了 CSS 模块并且使用了 ExtractTextPlugin 时,
        // 该 Chunk 就会生成 .js 和 .css 两个文件
        chunk.files.forEach(function (filename) {
          // compilation.assets 存放当前所有即将输出的资源
          // 调用一个输出资源的 source() 方法能获取到输出资源的内容
          let source = compilation.assets[filename].source();

      // 这是一个异步事件,要记得调用 callback 通知 Webpack 本次事件监听处理结束。
      // 如果忘记了调用 callback,Webpack 将一直卡在这里而不会往后执行。
🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
