The Big Picture - benhall/express-demo - Express.js

Express.js is a popular and widely-used web application framework for Node.js, simplifying the process of creating web applications and APIs. Installed in 2016, the latest version of Express.js is 1.0.0, and it’s used in over 7 other projects in the npm registry. To get started, simply run npm install express.js in your terminal.

Express.js offers a robust set of features for handling routing, middleware, and template engines, making it a popular choice for developers due to its minimalist design, flexibility, and ease of use.

Here’s a simple example of how to create a web server using Express.js:

1. Install Express.js using npm install express.js
2. Create a new file called app.js and add the following code:

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

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

app.listen(3000, () => {
console.log('Example app listening on port 3000!');
});

3. Start the server by running node app.js in your terminal.
4. Open your web browser and navigate to http://localhost:3000. You should see the message “Hello World!”.
