Which backend to choose for React APP?

Question

Backend

The applications will have a lot of data that needs to be updated Real Time. And for this, sockets will probably be needed.
The choice was between Django, PHP, Ruby on Rails, NodeJS (ExpressJS). It is obvious that Real Time + Sockets, the best option would be NodeJS with Express, and I think to take the base MongoDB (No SQL).
Googling, I came across the fact that the MERN stack, which is architecturally similar to my future application, is already outdated. Digging deeper into the new technologies GraphQL, Realm, Apollo, honestly, I still have no idea what they are for, some kind of new replacement for the REST API.
So the question arose of what would be the most ideal Backend for React APP today, preferably separate from Fronta. Maybe someone has an article or is there an example from github on this topic?

Answer 1

There is no perfect backend
