database - Best practice monogdb embed or not

Question

I'm just starting using MongoDB and more used to relational DBs. I want to store users (id, name ...) in one collection and posts (id, title, content, userID) in another. At the frontend, I want to show the posts including the user, who posted them. Obviously the username and not a cryptic id. In a relation DB, I would join the tables and sent the combined object to the frontend.

But what would be the best approach for a Mongo DB? Should I include the username in the posts collection or also join the collections? I'm really unsure about the joins in Mongo since I heard it should be avoided.

Thanks for any help or suggestions!
