How to create weather app in nodeJS

 Create server and Fetch API

const http = require('http');
var requests = require('requests');
const server = http.createServer((req, res)=>{
    console.log("server is running");
    if(req.url == '/'){
        requests("https://api.openweathermap.org/data/2.5/weather?q=Ahmednagar&appid=28e1107da44a4e4406402748f062d353")
        .on("data",(chunkData)=>{
            console.log(chunkData);
        })
        // .on("end",(err)=>{
        //     console.log("connection fail");
        // })
    }
});
server.listen(8000,'127.0.0.1',()=>{
    console.log('listening port no');
});

npm requests module usage

requests('https://google.com/foo/bar', { streaming })
.on('data', function (chunk) {
  console.log(chunk)
})
.on('end', function (err) {
  if (err) return console.log('connection closed due to errors', err);
 
  console.log('end');
});

            //no more data to read
            res.end();
