Satellizer gives you an illusion that you're doing an implicit grant flow by opening a popup and then magically you are signed-in. But authorization process is handled on the server: https://github.com/sahat/satellizer/blob/master/examples/ser...

I just implemented a GitHub sign-in and it took me only 8 minutes because on the server it was mostly copy-&-paste of the Facebook sign-in and on the client it's just:

  $authProvider.oauth2({
    name: 'github',
    clientId: 'xxxxxx',
    url: '/auth/github',
    authorizationEndpoint: 'https://github.com/login/oauth/authorize',
    redirectUri: window.location.origin
  });

Thank you. I like React too so perhaps someone could implement something like Satellizer that integrates with React.
