If using Google Firebase I want to compile a list of all the users who use my app (server side of course) and then return each user another user to work with, what Firebase product would I use. I initially thought I would use cloud functions but after watching some videos about cloud functions and reading the docs for cloud functions, I am more confused. I want all this code to be server side, not client side.
I watched some YouTube videos about cloud functions and read some documentation but now I am more confused about what exact Firebase product I should use to compile my list of users that, just for an extreme case, could be millions and then assign each user another user to communicate with on my app. The reason I want to do this all backend is because it is just safer. I know I could do this client side because I have no users for my app but the main thing I want to get out of this is how to set up backend code. By the way, I know that with Firebase authentication there is a list of users but I am more talking about taking that list of users and assigning each user with another user.
Thanks a lot!
