How to work with Node js backend and React js frontend?

Question

JavaScript

Hello everyone, I decided to try to work with a real Rest Api (with this https://openweathermap.org/api ) because of the CORS policy, javascript alone is not enough, you need a backend.
In this regard, the question is, now you always need two servers to run one for node js and the other for react js?
And how is it all then uploaded to the hosting? Maybe somewhere there is documentation or a video suitable or an example ready
