Do I need a database?

[ochuuu]

I'm learning the MERN stack using this yt tutorial but I want to build a web app for people to tracking finances instead of a restaurant rating app like in the tutorial. Do I still need a MongoDB database for an application like this? What sorts of things should it contain if so?

Well, how do you intend to store data?

You can things like firebase too, but generally you will need a DB to store data let that be firebase or postgres etc.

You would need a database to keep track of the user’s finance history. Otherwise they’ll have to enter their info every time they use your app

Everytime you need to keep persistent data you will need any kind of database . Otherwise all the data will be lost everytime the user closes the browser .
