I think maybe this is a good place to post this since I have only a front end experience. So I would like insights from people that are also in front-end.

I have a project in mind that would require a good server with a database. I have never created a solid back-end before, aside from a small API in nodejs.

I want to learn and create a good back end, one that is scalable. I thought to use GraphQL for querying, maybe Apollo on the front end. But what about the back end?

I am willing to learn a new language if necessary, or can I do all that “back end languages” do with nodeJS? Where to set my database? Where to host my API?

Could you guys give some light? Thanks!
