expressjsHow do I set up an Express.js engine for my web application?

Setting up an Express.js engine for your web application is a relatively simple process.

1. Install the Express.js module:

$ npm install express

2. Create a server.js file in the root of your project directory.

3. Require the Express.js module in the server.js file:

const express = require('express');

4. Create an instance of Express.js in the server.js file:

const app = express();

5. Set up routes and middleware in the server.js file.

6. Set the port for the server to listen on:

const port = 3000;

7. Start the server:

app.listen(port);

You should now have a basic Express.js engine set up for your web application.
