Explain how to use Blade layouts in Laravel.

In Laravel, Blade layouts provide a simple way to maintain a consistent look and feel across your application by reusing common components. Here’s how to set up and use Blade layouts effectively:

1. Create a Layout File

First, create a Blade file (e.g., resources/views/layouts/app.blade.php) that will serve as the master layout for your site. This layout should include the main structure of your HTML page, such as headers, footers, and common elements. Use the @yield directive to define placeholders for content that will change across different pages.

Example

<!-- layouts/app.blade.php -->
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Application</title>
</head>
<body>
    <header>
        <h1>My Site</h1>
    </header>

    <main>
        @yield('content')  <!-- Dynamic content goes here -->
    </main>

    <footer>
        <p>© 2024 My Application</p>
    </footer>
</body>
</html>

2. Extend the Layout

Next, in your individual view files, you can “extend” the layout file using the @extends directive. This allows you to inject content into the layout’s defined sections using the @section directive.

Example

<!-- home.blade.php -->
@extends('layouts.app')

@section('content')
    <h2>Welcome to my site!</h2>
    <p>This is the homepage content.</p>
@endsection

3. Render the Views

In your controller, you can render the view by simply returning it. Laravel will automatically apply the layout file when rendering the view.

Example

<?php
// HomeController.php
public function index() {
    return view('home');
}
?>

Why Use Blade Layouts?

Blade layouts help streamline your development by promoting code reusability. Instead of repeating the same header, footer, or sidebar code across multiple pages, you can define it once in a layout and then focus only on page-specific content. This also ensures a consistent design across your entire application and makes future updates much easier.

With Blade layouts, you keep your views modular, reducing repetition and making your application more maintainable.
