Getting started with Node

Node is for communication with the Server-side. Server files always end in .js , and communication is almost always done in the json format.

Add this to the top to specify that it is a server:

const http = require('http');

After that, add this:

const server = http.createServer((req, res) => { ~Body of server~ });

req is for Request and res is for the Response of the server respectively.

Use this line of code to specify the localhost number you want your server to listen in to:

server.listen(a valid locahost number)

If you change something in your server’s code, you might need to quit the cmd and restart node to see the changes.
