I have written the frontend of an application using React.js and whose backend REST API is built using Spring boot.
I am successful is in integrating the "social login for Facebook" from frontend and now I have this information returned from facebook
Now, my requirement is to create an account of this user into my own application(own Database) using the user's email as the primary key for his/her account. This user will have its own content(likes, interests, feeds).
But I have no idea where should I start now, what would be the flow of the backend API and the complete application.
