WCS - Node.js - Creating an http server

const http = require('http');
const port = 8000;
const url = require('url');

const requestHandler = (request, response) => {
    const parsedUrl = url.parse(request.url, true);
    if(parsedUrl.query.name && parsedUrl.query.city){
        response.end(`Hello, ${parsedUrl.query.name} from ${parsedUrl.query.city}`);
    }else{
        response.end("Please provide name AND city parameters");
    } 
} 

const server = http.createServer(requestHandler);

server.listen(port, (err) =>{
    if(err){
        console.error("Something bad happened");
    }else{
        console.log(`server is listening on ${port}`);
    }
})
