How to create a simple application with react, nodejs and mongodb?

Question

JavaScript

How to start creating such an application? As I understand it, not with create-react-app, but with a node, and then connect the react?
Maybe there is an example of a simple application on react + nodejs + mongodb. Let's say a list of 5 items is displayed, which is taken from mongodb, the list item can be deleted. Here, maybe there is an example of such a simple application (or similar) somewhere? And how to implement this? Exactly where to start? Thank you.
ps links to courses on creating a complex application do not need to be given, it is important for me to understand how it works with a small simple example.

Answer 1

I asked myself this question when I was studying, I don’t remember what I found
But here is one of my first projects for react, node and mongo https://github.com/Jeerjmin/weather-app
If you write in telegram, I will answer a couple of questions on project

Answer 2

react+nodejs+mongodb

This can already be considered a complex application because 3 simple applications interact with each other.
If simplified: frontend (in the form of react.js, but can be any), communicates with backed (node.js, but can be any - the same php or ruby), which makes a change to the database (mongodb, but can be any , the same mySql).
A simple example based on Vue.js can be found here: https://github.com/DarkScorpion/vue2-express-blank. See the logic of creation and build and run better with package.json scripts section.
