title: How to make an Angular app witch Universal SSR use dynamic configurations from json file?
body: <p>I was assigned the task of making a dynamic load of settings for the Angular application from the JSON file on the server during the application start. The peculiarity is that the application uses server rendering with Universal.
  I tried to do this for the browser using this method.

  But it works only for the browser app rendering.
  How to do it for server-side rendering?</p>
