file: An app shell lets Universal render a portion of your application via a route at build time.
  This gives users a meaningful first paint of your application that appears quickly
  because the browser can simply render the HTML without the need to initialize any JavaScript.
  
  Use this command with a routing app that is accompanied by a Universal server-side app.
  
  To create an app shell, use the following command.
  
  <code-example format="." language="bash">
   ng generate app-shell my-app
  </code-example>
  
  - `my-app` is the name of your client application
  - `server-app` is the name of the Universal (server) application
  
  The command adds two new architect build targets to your `angular.json` configuration file (along with a few other changes).
  
  <code-example  format="." language="none" linenums="false">
  "server": {
    "builder": "@angular-devkit/build-angular:server",
    "options": {
      "outputPath": "dist/my-app-server",
      "main": "src/main.server.ts",
      "tsConfig": "src/tsconfig.server.json"
    }
  },
  "app-shell": {
    "builder": "@angular-devkit/build-angular:app-shell",
    "options": {
      "browserTarget": "my-app:build",
      "serverTarget": "my-app:server",
      "route": "shell"
    }
  }
  </code-example>
  
  To verify the that the app has been built with the default shell content:
  
  1. Run the app-shell target.
  
     <code-example format="." language="bash">
         ng run my-app:app-shell
      </code-example>
  
  1. Open `dist/app-shell/index.html` in your browser.
  
  The default text "app-shell works!" verifies that the app-shell route was rendered as part of the output.
