Here is a step-by-step guide to creating a simple express server:

Install the express package using npm (the Node.js package manager). You can do this by running the following command: npm install express

Create a file for your server, such as server.js, and add the following code to it:

const express = require('express')
const app = express()

app.get('/', (req, res) => {
res.send('Hello, world!')
})

app.listen(3000, () => {
console.log('Server is listening on port 3000')
})

Run the server using the following command: node server.js

You should see the message Server is listening on port 3000 printed to the console. This means that the server is now running and listening for incoming requests on port 3000.

You can test the server by opening a web browser and navigating to http://localhost:3000. You should see the message "Hello, world!" displayed on the page.

That's it! You have just created a simple express server. You can now build on this foundation to create more complex web applications using Node.js and express.

Add models, views and controller
