Node.js server just keeps loading with no result - node.js

Question

server.js
const http = require('http');
const app = require('./app');
const port = process.env.PORT || 3000;
const server = http.createServer();
server.listen(port);
app.js
const express = require('express');
const app = express();
const productRoutes = require('./api/routes/products');
app.use('/products', productRoutes);
module.exports = app;
so when i just run the code node server.js it just keep looping without any result.

Check out this link It gives a bit more detail on how that works.
const http = require('http');
const net = require('net');
const url = require('url');
// Create an HTTP tunneling proxy
const proxy = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('okay');
});
proxy.on('connect', (req, cltSocket, head) => {
// connect to an origin server
const srvUrl = url.parse(`http://${req.url}`);
const srvSocket = net.connect(srvUrl.port, srvUrl.hostname, () => {
cltSocket.write('HTTP/1.1 200 Connection Established\r\n' +
'Proxy-agent: Node.js-Proxy\r\n' +
'\r\n');
srvSocket.write(head);
srvSocket.pipe(cltSocket);
cltSocket.pipe(srvSocket);
});
});
// now that proxy is running
proxy.listen(1337, '127.0.0.1', () => {
// make a request to a tunneling proxy
const options = {
port: 1337,
hostname: '127.0.0.1',
method: 'CONNECT',
path: 'www.google.com:80'
};
const req = http.request(options);
req.end();
req.on('connect', (res, socket, head) => {
console.log('got connected!');
// make a request over an HTTP tunnel
socket.write('GET / HTTP/1.1\r\n' +
'Host: www.google.com:80\r\n' +
'Connection: close\r\n' +
'\r\n');
socket.on('data', (chunk) => {
console.log(chunk.toString());
});
socket.on('end', () => {
proxy.close();
});
});
});

const http = require('http');
const app = require('./app');
const port = process.env.PORT || 3000;
const server = http.createServer();
server.listen(port);
As far I could extract from code, the thing that is most probably happening in your server.js is that your server is waiting for some request. And you have nothing in your code handle requests.

I think you have to call the require function to return the actual router object, try to change this line
from: const productRoutes = require('./api/routes/products');
to: const productRoutes = require('./api/routes/products')();
