title: Angular2 - Authentication with auth0 or rails?
body: <p>Cause i'm new to the whole angular (specific angular2) thing i wonder about something.</p>
  
  <p>I want to build an "api" backend with rails 5 as they released the api mode and my frontend with angular2. Because i'm used to rails i wanted to implement a devise user authentication and because i'm new to angular2 i searched for a way to authenticate the user against my rails/devise backend. </p>
  
  <p>But all i find are tutorials about angular2 and auth0, which i never heared before. </p>
  
  <p>So my question is, is it "normal" to user angular2 with auth0 authentication?
  And when i use auth0 my user data are not in my database right? So how do i create relationships with my rails models?</p>
  
  <p>Would be great if someone can explain that to me or link me some article if they exists.</p>
