Express Router

• We can use express Router as follows:

const express = require('express');
const router = express.Router();

• Or use destructuring like this:

const { Router } = require('express');
const router = Router();

Express Request and Response

• We can activate the intellisense with "express.request" and "express.response":

const express = require('express');

const controllerName = (req = express.request, res = express.response) => {
  res.json({
    message: 'Message from controller of route!',
  });
};

• Or use destructuring like this:

const { request, response } = require('express');

const controllerName = (req = request, res = response) => {
  res.json({
    message: 'Message from controller of route!',
  });
};

CORS - Cross Origin Resource Sharing.

• Is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served. More on Wikipedia...
