node.js: URL-based requests

Hi people!!

Today I will demonstrate how node.js can respond based on the URL.

1st step: Open the command line and enter the following commands:
- mkdir URL-requests
- npm init
- touch require.js

Before proceeding to the 2nd step, the theme for our code will be about a computer store and that we will have the following categories:
- Laptops;
- Smartphones;
- Tablets.

2nd step: Insert the following code

var http = require('http');
var server = http.createServer(function(req, res) {
var cat = req.url;
if (cat == "/laptops"){
res.end('Laptops Category');
} else if (cat == "/smartphones") {
res.end('Smartphones Category');
} else if (cat == "/tablets") {
res.end('Tablets Category');
} else {
res.end("Technology Store")
}
}).listen(8085);

3rd step: Run the following command

node require.js

And ready, these are the final results:

http://localhost:8085/

http://localhost:8085/laptops

http://localhost:8085/smartphones

http://localhost:8085/tablets

I hope you enjoyed!!
