When we use http.createServer() in Node.js

I just started learning Node.js, and I'm wondering when developer should/need to use http.createServer()

My process of thinking is: "When I want to catch data from server I use: http.request and http.get methodes.



When I want to POST on server I will use http.request with POST method options parameter.

I just can’t figure out, when I should use http.createServer() method?



If I work on remote server (server is already exists).

I red documentation: This class is used to create a TCP or IPC server.

w3School says: The http.createServer() method turns your computer into an HTTP server.

If you can, give me comprehensive explanation with real world example.

Thanks

When you use something like http.request(), you're connecting to another HTTP server and requesting data from it. If you wanted to be that server yourself, you would need to use http.createServer() to do that.

For example, a common use case of Node.js is to create an API server that receives HTTP requests from web pages and fetches or manipulates data in a database. It takes the resulting data and sends it as an HTTP response.

The Node.js documentation you read seems to be for net.createServer(). While http.createServer() does create an underlying TCP server, it also accepts a callback for listening for HTTP requests.
