Hi all. Please pardon my stupid question, but I'm still learning front end, so everything about the back end is mystifying to me.
I've built an app for learning purpose, but it's just occurred to me that one day I'd like to integrate user registration and authentication into it. So what language/framework/platform do I need to learn? Laravel, Mongdb, asp.net, AWS or anything else?
I don't mind anything, but it's be a plus if it can integrate well with React or Vue, since it is what I'm more familiar with.
