/**
* *** NOTE ON IMPORTING FROM ANGULAR AND NGUNIVERSAL IN THIS FILE ***
*
* If your application uses third-party dependencies, you'll need to
* either use Webpack or the Angular CLI's `bundleDependencies` feature
* in order to adequately package them for use on the server without a
* node_modules directory.
*
* However, due to the nature of the CLI's `bundleDependencies`, importing
* Angular in this file will create a different instance of Angular than
* the version in the compiled application code. This leads to unavoidable
* conflicts. Therefore, please do not explicitly import from @angular or
* @nguniversal in this file. You can export any needed resources
* from your application's main.server.ts file, as seen below with the
* import for `ngExpressEngine`.
