what is the difference between using Express GET method and HTTPS GET method in the below code?

Question

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

app.get("/", function (req, res){
  var url = "https://***";
  https.get(url, function(response){
    console.log(response);
  });
  res.send("server running");
});

Answer 1

Express is really just a layer on top of http. I reckon those following links might help you out, this question has been asked.

• what's the technical difference between express and http, and connect for that matter
• Difference between a server with http.createServer and a server using express in node js

Answer 2

app.get() registers a listener for a specific INCOMING http request path on a local Express server.

https.get() makes an OUTBOUND https request TO some other https server to fetch content from that other server.

And, obviously, the https.get() is using https, not http. The app.get() could be listening for either - it depends upon how the server it is part of is started (as an http server or an https server) which the code you have in your question does not show.
