title: Identityserver4 authentication - login and registration handled in client angular application without redirection
body: <p>Is it possible to handle login and registration in identityserver4 using asp.net identity and to <strong>not</strong> be redirected to server page from client javascript(angular5) app?</p>
  
  <p>I am developing app that consists of multiple API's. I want to have all of them protected but one (frontoffice) should be accessible both from angular by lets say individual user accounts and by other API's. While I'm able to do API to API authorization (from tutorials) i'm struggling a bit with angular one. I saw identityserver4 doc's page but theres no mention if its possible to implement this concrete scenario.</p>
  
  <p>Do i have to live with this redirection or is it possible to make a direct call from angular or something? Maybe there is some different library that i can use except identityserver?</p>
