How to implement social logins in MEAN stack?

I have successfully implemented multiple social logins in Node JS.

I'm stuck with the implementation in MEAN stack.

The flow I have implemented till now:

Step 1:

Button in Angular. On Click, I'm calling an API in Node which returns the OAuth URL to which the user has to be forwarded.

Step2:

Once the user enters his correct credentials, access_token is generated and sent to callback URL in Node.

Step3:

I need to send a callback to Angular, whether access_token has been generated or not. I'm not sure as to how I should pass data to Angular Page.

Is this the right approach?
