How do I create a simple Express app?

To create a simple Express app, first, ensure you have Node.js installed. Then, create a new directory for your app.

What files do I need to create in that directory?

You need to create a package.json file and an index.js file. The package.json will manage your dependencies.

How do I set up the package.json file?

You can set it up by running npm init -y in your terminal, which will create a default package.json file.

What code should I put in the index.js file?

In index.js, you can start with const express = require('express'); const app = express(); app.listen(3000, () => console.log('Server running on port 3000'));.
