I'm creating a e-commerce website with node and angular. I have made server with node, created api with all the endpoints, designed datebase. Fetching data and showing it with angular works.
But I have a problem with user authentication, I heard about Auth0 but problem is that I am storing users data (watchlist,shopping cart etc.) in my postgres datebase and I can't find any example how to get personal user data from my db with it.
