title: Angular universal rendering for some routes only
body: <p>I was playing with angular universal a bit but cant find option to use server side rendering only for some pages like home page and render all other routes in standard angular way. I don't want to use server side rendering for private pages where SEO is not needed. I can  configure routes in express like this</p>
  
  <pre><code>// send all requests to Angular Universal
  // if you want Express to handle certain routes (ex. for an API) make sure you adjust this
  app.get('/', ngApp);
  app.get('/home', ngApp);
  app.get('/about', ngApp);
  </code></pre>
  
  <p>Ideally I don't want to know about NodeJs at all and configure it on angular routes config with property like serverSide: true</p>
  
  <pre><code>const appRoutes: Routes = [
    //public route, I want server rendering for SEO
    { path: 'home', component: HomeComponent, serverSide: true },
    //private user profile page, SEO is not needed
    { path: 'user/profile/:id', component: UserProfileComponent },
  ];
  </code></pre>
