How to pick a right hardware configuration setup(server) for MERN stack

Question

I'm learning programming(MERN stack) and along with that basic DevOps(linux, containers etc). I've read a lot about software configuration setups(with NGINX, and without, etc), but can't find anywhere regards how well the MERN stack will behave on different server hardware configuration setups.

I will probably host my app on Linode, for various reasons(price, anti-ddos etc), but I guess it will applicable for alike services too(digital ocean etc).

So, is there a way to approximately know before deploying, how much my app will need resources? Are there any assumptions I can make regards MongoDB's usage(of RAM, for example?), for example?

Any info will be valuable for me, thank you.

Since this is for your learning, it shouldn't tax your hardware incredibly. If you are hosting I would with a free student account if you can. But if you have a linux laptop all of this should work well on it. You're not writing apps that are getting 10,000's of connections and transforming complex data. If you had an enterprise app I would indeed split off the DB from the frontend etc.
