NodeJS - Requesting URL Path, Method and Query from Simple Web Server

[farizal]

After we got our Simple NodeJS Web Server up and running, we can add more code to request URL path, method and query.

And the steps are 5:

1. Add another NodeJS dependencies which is: const url = require('url');

2. We create parsed URL object inside the http server function: let parsedUrl = url.parse(req.url,true);

3. From the parsed URL we get the URL path: let path = parsedUrl.pathname;

4. From the http request we get the method: let method = req.method.toLowerCase();

5. Print the output with console.log.

Below are the full code:

//dependcies
const http = require('http');
const url = require('url');

// Create the server
let server = http.createServer( function(req,res){

    //Get URL and parse it
    let parsedUrl = url.parse(req.url,true); 

   //Get the URL path
   let path = parsedUrl.pathname;


   //Get query String as an object
   let queryStringObject = parsedUrl.query;

    //Get the HTTP method
    let method = req.method.toLowerCase();
 
    //send respond
    res.end('Hello world\n');

    // Log the request path
    console.log('Request received on path:' + path + 'with method ' + method);
    console.log('With these query String parameters: ', queryStringObject);
  });

// The server created listen to port
server.listen(3000,()=>{
    console.log('Server listening on port 3000');
});
