Node.js for forwarding information from a third-party API

Question

What I want to do with Node.js is basically LISTEN to an API (json) and process the results to send to multiple clients.

Example:

What I want to know is: This My VPS computer has to exist and run the server application for 24 hours?

I thought of something like a Crontab to replace the VPS, but I think I’m wrong about this, because Node.js should be "LISTENING" to the API and not accessing it through multiple requests in a given time interval.

Could I leave the script running on the server itself forever?

I see several notifications apps that collect third-party data and wonder if that’s how they work.

Answer 1

Research on socket., it maintains a bidirectional connection(websocket) with any customer that connects, so you can create private rooms, login mechanisms, etc.

Can send messages from client to server and vice versa.
