Morgan for HTTP request logging in Express - Mini Project: Build & Apply

Morgan for HTTP request logging

📖 Scenario: You are building a simple Express web server. You want to log every HTTP request your server receives to help monitor traffic and debug issues.

🎯 Goal: Set up the morgan middleware in an Express app to log HTTP requests in the 'tiny' format.

📋 What You'll Learn

Create an Express app instance called app

Import and use the morgan middleware with the 'tiny' format

Add a basic route / that sends 'Hello World!'

Start the server on port 3000

💡 Why This Matters

🌍 Real World

Logging HTTP requests helps developers monitor traffic and troubleshoot issues in web servers.

💼 Career

Understanding middleware like Morgan is essential for backend developers and DevOps engineers to maintain and debug web applications.

1

Create the Express app

Import express and create an Express app instance called app.

Express

const express = require('express');
// Your code here

Need a hint?

Use const app = express(); to create the app.

2

Import and configure Morgan middleware

Import morgan and use it as middleware in app with the 'tiny' format.

Express

const express = require('express');
const app = express();
// Your code here

Need a hint?

Use app.use(morgan('tiny')); to add logging.

3

Add a basic route

Add a GET route for '/' that sends the text 'Hello World!' as the response.

Express

const express = require('express');
const app = express();
const morgan = require('morgan');
app.use(morgan('tiny'));
// Your code here

Need a hint?

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

4

Start the server

Start the Express server on port 3000 and print 'Server running on port 3000' when it starts.

Express

const express = require('express');
const app = express();
const morgan = require('morgan');
app.use(morgan('tiny'));
app.get('/', (req, res) => {
  res.send('Hello World!');
});
// Your code here

Need a hint?

Use app.listen(3000, () => { console.log('Server running on port 3000'); });
