nodejs post method not getting called - node.js

Question

I found my question was asked a year ago here app.post() not working with Express but the code written there is outdated (the way bodyparser was added doesn't work anymore as well as function mentioned below) plus the asker never chose an answer so the question was never solved.
Here's my code
const express = require("express");
const db = require("mysql");
const app = express();
const bodyParser = require("body-parser");
const multer = require("multer"); // v1.0.5
const upload = multer(); // for parsing multipart/form-data
const http = require("http");
const path = require("path");
app.set("view engine", "jade");
app.set("views", path.join(__dirname));
console.log("before");
app.listen(8000, () => {
console.log("Server started!");
console.log("within");
});
console.log("after");
app.use(bodyParser.json()); // for parsing application/json
app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded
app.post("/", function(req, res) {
console.log("hit here in post");
res.render("index.jade", {});
console.log("hit here in post");
res.json({ name: "John" });
res.status(500).json({ error: "message" });
res.end();
});
app.get("/", function(req, res) {
res.render("index.jade", {});
console.log("hit here in get");
console.log(req.body);
});
Here's the output.
before
after
Server started!
within
hit here in get
{}
I even tried to wrap the app sets and uses in app.configure like the asker of the other question to see if that was the issue but that configure function doesn't seem to exist anymore because I got an error about it.
Also I should probably note. My routing here is correct. I haven't made a views subfolder yet so that's why I have it written as it is.
Update
I think I may have spotted the issue but I don't understand why it's occurring. In the network tab of the browser I see that GET is getting 404 error because of a favicon.ico request but I don't understand where that request is coming from. I've seen the serve-favicon npm module to support it but didn't want to added because I never intended to add a favicon image to my server. I don't even understand how that would work.

What do you mean by I configure the middleware after it has started? Are you referring to the fact that the post method is written after port listening has started? Also if that's the reason why post isn't executing how come the get method executes regardless of that? I'm not holding back any server code aside from code I currently have commented out for the moment but that code I posted is my main index.js file and it's the only file I modified from the standard npm init project. I haven't setup any routes because I don't see the need to do so (even when I add react since my project is simple in concept of communication between reactjs, nodejs and a database "hence my frustration") which is why I'm trying to have get and post only access the root directory.

favicon is automatically requested by the browser. it is the icon used in the browser tab or url address bar
Add this, before app.get():
app.all('/', function(req, res, next) {
console.log({method: req.method, url: req.url});
next();
});
