17:45 Sir, I am lucky that I am studying from you. Mai apko + Documentation + chatgpt ko use karta hu for understanding all the concepts clearly. Yahatak pohochke mai itna bol sakta hu ki I can create all this now without any help. Apne bola ki ye hard hai lekin mai chok gaya ki phir bhi itna easily kaise samajh agaya. Trust me, I am not that kind of intelligent kid. Mujhe kabhi kabar simple chis bhi 4 ghante continuous ragadne ke baad clear hota hai jo bakiyo ko adha ek ghanta lagta hai. Thank you so much sir. #sigmawebdevelopment

How can we use import i.e type - module and connect blog.js to our index.js
this was my blog.js in my routes folder of the current dir :
// Import the required modules
import express from 'express';
// Create an Express router
const router = express.Router();
// Define root of the blog
router.get('/', (req, res) => {
res.send('Welcome to the root of the blog');
});
router.get('/:first', (req, res) => {
res.send(`Welcome to ${req.params.first} blog`);
});
router.get('/:first/:second', (req, res) => {
res.send(`Welcome to ${req.params.first} in ${req.params.second}`);
});
// Export the router
export default router;
/* blog.js ENDS HERE */
now in main.js :
import express from 'express';
import blogHandler from './routes/blog.js'; //instead of blogHandler u can use another name as well
// Create an Express app
const app = express();
// Use the blogHandler for the '/blog' route
app.use('/blog', blogHandler);
/* DEFINING PORT NUMBER AND OTHER THINGS TO SET UP SERVER CAN BE DONE AS BEFORE */
});
/* main.js ENDS HERE */
