Introduction
Laravel Blade is a powerful templating engine that allows developers to create dynamic, reusable views with ease. Blade offers a clean syntax and a host of features that make it a preferred choice for rendering views in Laravel applications. In this guide, we’ll explore Blade’s core features, how to use its syntax, and best practices for creating dynamic views.
If you’re new to Laravel, you might want to start with our introduction to Laravel to get a solid foundation before diving into Blade templating.
What is Blade Templating?
Blade is the simple yet powerful templating engine that comes built-in with Laravel. Unlike other PHP templating engines, Blade does not restrict you from using plain PHP code in your views. It provides a set of convenient shortcuts and directives that help you build complex layouts with less code.
Blade files use the .blade.php extension and are typically stored in the resources/views directory.
Basic Blade Syntax
Blade’s syntax is designed to be intuitive and easy to learn. Here are some basic examples:
1. Echoing Data
To display data in Blade, you use the double curly braces {{ }} syntax:
<h1>Welcome, {{ $name }}</h1>This will safely echo the value of $name, escaping any HTML entities to prevent XSS attacks.
2. Blade Directives
Blade comes with several directives that simplify common tasks:
Conditionals:
@if($isLoggedIn)
<p>Welcome back!</p>
@else
<p>Please log in.</p>
@endif
Loops:
@foreach($users as $user)
<li>
{{ $user->name }}
</li>
@endforeach
Comments: Blade also supports inline comments

Layouts and Sections
Blade makes it easy to create layouts that can be extended by individual views. This promotes reusability and keeps your code DRY (Don’t Repeat Yourself).
Creating a Layout
First, you define a layout in a Blade file, for example, layout.blade.php:
<!DOCTYPE html>
<html>
<head>
<title>@yield('title')</title>
</head>
<body>
@yield('content')
</body>
</html>
Extending a Layout
To extend the layout, use the @extends directive in your view file:
@extends('layout')
@section('title', 'Home Page')
@section('content')
<h1>Welcome to the Home Page</h1>
@endsection
This structure allows you to define a common layout and have multiple views that share the same structure.
Components and Slots
Blade also supports components, which are reusable pieces of a view that can be easily included in multiple places. Components are useful for creating elements like navigation bars, modals, or cards.
Creating a Component
You can create a Blade component by placing a Blade file in the resources/views/components directory. Here’s an example of a button.blade.php component:
<button class="btn {{ $type }}">
{{ $slot }}
</button>
Using a Component
To use this component in a view, you can include it like this:
<x-button type="primary">
Click Me
</x-button>
The {{ $slot }} directive in the component captures everything between the component’s tags.

Blade Includes
Blade’s @include directive allows you to include another Blade view inside your view. This is particularly useful for repeating elements like headers, footers, or sidebars:
@include('partials.header')
Using @include, you can keep your views clean and modular.
Rendering Data with Blade
Blade can easily render data passed from a controller. For example, if a controller passes an array of users to a view:
return view('users.index', ['users' => $users]);
You can loop through and display this data in the Blade view:
@foreach($users as $user)
{{ $user->name }}
@endforeach
This makes Blade a powerful tool for dynamically generating content based on data from your application.
Conclusion
Blade templating is an essential part of Laravel, offering a simple yet powerful way to create dynamic views. With its clean syntax and flexible features, Blade makes it easy to build and maintain complex layouts. By mastering Blade, you’ll be able to create more efficient and organized views in your Laravel applications.
