title: Add additional angular libraries at runtime (not declared as routes)
body: <p>Do you know if there is a way to dynamically add routes &amp; libraries <strong>at run-time</strong> for an angular app ?
  Even with lazy loading mechanism, all the routes <strong>must be defined in a typescript routing file</strong> (so that angular compiler can generate chunks at build-time). I didn't find a way for an app, to load additional routes and libraries on demand at runtime.</p>
  <p>The idea behind that, is that whenever an angular app starts, it looks inside a json file for the libraries it should load. It then dynamically populates the router with those routes and associates a module to lazy-load when the user will click on a route. By doing that, we could add some new features to an app, without having to rebuild it.</p>
  <p>Any ideas ?
  Thanks :)</p>
