How to accept data from another resource on nodejs/express?

Question

JavaScript

Good afternoon! Please tell me how to accept data in nodejs/express from another resource and send it to the client?
I’m just starting to understand the node (more on the front), so sorry for the stupid question, I can’t google something.
It is not clear whether they need to be processed or not, to prescribe some headers ... I
figured out how to send a string or something like that, but I can’t accept data from another resource and send it.
I would be grateful for any help!

To receive data, you must first make a request, either ajax if through the front or request if through the back. After that you get a response, you can send the response to the front via res.json for example.
