4. Step-by-Step Guides, Tutorials, and Examples: Learning by Doing

Step-by-Step Guide to Building a Simple Web Application:

1. Set up the Environment:

Install Node.js and npm (Node Package Manager).
Create a new project directory.
Initialize a new project using npm init -y.

2. Install Dependencies:

Install the Express framework: npm install express.
Install a template engine like EJS: npm install ejs.

3. Create the Server:

Create an app.js file.
Import the required libraries: const express = require('express'); const app = express();.
Set up the view engine: app.set('view engine', 'ejs');.

Define routes and handle requests:

app.get('/', (req, res) =&gt; {
    res.render('index'); // Render the 'index.ejs' template
});

4. Create the Template:

Create an index.ejs file in the views directory.

Add the HTML structure and content:

<!DOCTYPE html>
<html>
<head>
<title>
My Web App
</title>
</head>
<body>
<h1>
Welcome to My Web App!
</h1>
</body>
</html>

5. Run the Server:

Run the server using node app.js.
Access the application in your browser: http://localhost:3000/.

Code Snippet:

// app.js
const express = require('express');
const app = express();
app.set('view engine', 'ejs');

app.get('/', (req, res) =&gt; {
  res.render('index');
});

app.listen(3000, () =&gt; {
  console.log('Server listening on port 3000');
});

Tips and Best Practices:

Follow a coding style guide: Consistent formatting makes your code easier to read and maintain.
Write clear and concise comments: Explain the purpose of your code and help others understand it.
Test your code thoroughly: Writing unit tests helps ensure your code works as expected and catches errors early.
Use version control: Track your code changes, collaborate with others, and revert to previous versions easily.
