My code is
//Using the previous code with few changes.
const express = require('express'); //Imported the module I installed in last leture
const path = require ('path');
const app = express(); //Created my app
const port = 80; //The port on which i want to listen.
// Setting template engine as pug
app.set('view engine', 'pug')
//Set the views directory
app.use('views', path.join(__dirname, 'views'));
//Our pug demo end point
app.get("/demo", (req, res)=>{
res.status(200).render('demo', { title: 'Hey Harry', message: 'Hello there and thanks for telling me how to use pubG!' })
});
app.get("/", (req, res)=>{
res.send("This is home page of express app")
})
app.get("/about", (req, res)=>{
res.status(200).send("This is get request of about page of express app")
})
app.post("/about", (req, res)=>{
res.send("This is post request of about page of express app")
})
app.get("/this", (req, res)=>{
res.status(404).send("Page not found");
})
app.listen(port,() =>{
console.log(My express app is successfully started at port ${port});
})
I have tried the
const router = express.router();
module.exports = router;
