Searching Tutorials and Tipps for ionic 5 mysql angular12

Hello people,
I am looking for an actual tutorial for ionic5 angular mysql login.
I want to create a login app with existing data from mysql database. My weak point at the moment is to integrate the backend into the ionic project.
I have already found some tutorials on the net and worked through them, but most of them are still leading earlier versions of ionic and angular.

I would also appreciate any other tips for my project.

You’re going to need to write a middleware server that responds to REST endpoints and speaks to the database. I would use JWT for the authentication protocol. Further, I would suggest anything but JavaScript/TypeScript for the backend language, because having different implementation languages for the frontend and backend ensures that you won’t be tempted to reuse code across them.
