-    // While we're investigating better solutions, for now we will take a
-    // compromise. Since our WDS configuration only serves files in the `public`
-    // folder we won't consider accessing them a vulnerability. However, if you
-    // use the `proxy` feature, it gets more dangerous because it can expose
-    // remote code execution vulnerabilities in backends like Django and Rails.
-    // So we will disable the host check normally, but enable it if you have
-    // specified the `proxy` setting. Finally, we let you override it if you
-    // really know what you're doing with a special environment variable.

-    // By default WebpackDevServer serves physical files from current directory
-    // in addition to all the virtual build products that it serves from memory.
-    // This is confusing because those files won’t automatically be available in
-    // production build folder unless we copy them. However, copying the whole
-    // project directory is dangerous because we may expose sensitive files.
-    // Instead, we establish a convention that only files in `public` directory
-    // get served. Our build script will copy `public` into the `build` folder.
-    // In `index.html`, you can get URL of `public` folder with %PUBLIC_URL%:
-    // <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
-    // In JavaScript code, you can access it with `process.env.PUBLIC_URL`.
-    // Note that we only recommend to use `public` folder as an escape hatch
-    // for files like `favicon.ico`, `manifest.json`, and libraries that are
-    // for some reason broken when imported through Webpack. If you just want to
-    // use an image, put it in `src` and `import` it from JavaScript instead.
