Use angular 4 login form to authenticate the app with IdentityServer 4

Is there a way to use a login form from my angular 4 application and post to the identityserver 4 project in order to authenticate the Angular app.

I'm using oidc-client in the Angular app

Actually, to authenticate the Angular App, the user is redirect to the Identity Server 4 project where the login form is sit, then return back to the angular app with the token. This token is saved and used to call Web API application.

Thanks a lot
