But if i am using http its working fine even i have tried with node install https (still not work)

Answer 1

Your doing https request and your url starts with http:// when it should be https:// .

Answer 2

The problem with the code is that you are making https request and in your url you are using "http" instead of "https" . So if you change your url to "https" it should work.

https://api.openweathermap.org/data/2.5/weather?q=Gwalior&appid=4b01458a2b74d57ff37f136f382ac4d5&units=metric

I know you have figured this out but for the purpose of those that might run into this in the future - So the code should be:

const express = require("express");
var https = require("https");


const app = express();


app.get("/", function(req, res) {

    const url = "https://api.openweathermap.org/data/2.5/weather?q=Gwalior&appid=4b01458a2b74d57ff37f136f382ac4d5&units=metric";

    https.get(url, function(response) {
        console.log(response.statusCode)
    });
    res.send("Server is Up and Running");
})



app.listen(3000, function() {
    console.log("Server is running on port 3000.");
})
