Can you recommend an example application in react and express js for a beginner?

Question

JavaScript

The task is to write a site with several sections using the following technology stack:
React, Express, Mongo, the rest is optional.
What are some good open source examples?
I don't want to do server rendering until I get to that point, I'll just get more confused. It is desirable, if any, examples without it. And so that there are sections on the site - i.e. to use react-router. And from what I found - examples of a single-page 'todo-application'.
