Answer 1

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

http.createServer((req,res)=>{

    const parseObj =  url.parse(req.url,true);
    const users = [{id:1,name:'soura'},{id:2,name:'soumya'}]

    if(parseObj.pathname == '/user-details' && req.method == "GET") {
        let Id = parseObj.query.id;
        let user_details = {};
        users.forEach((data,index)=>{
            if(data.id == Id){
                user_details = data;
            }
        })
        res.writeHead(200,{'x-auth-token':'Auth Token'})
        res.write(JSON.stringify(user_details)) // Json to String Convert
        res.end();
    }
}).listen(8000);

I have used the above code in my existing project.
