Authentication flow for React/Node/Express stack?


sorry for the naive question, I’m trying to implement Auth0 for the first time.

I am writing code for this app with this regular auth flow.

From a React frontend form, Users send a registration request to the Node API.
Username and password are saved into my DB.

In my MySQL DB, every User has a relationship with many Posts.
When user authenticates himself, React calls the API to get the Posts of that user and load them on page.

I have trouble finding the right workflow in the guides and quickstarts.
I’m completely disoriented.

Someone has a hint?
