Introduction to Blade Template in Laravel

Blade is Laravel’s built-in templating engine designed to make front-end development smoother, cleaner, and more expressive. While many PHP frameworks either rely on plain PHP templates or external template engines, Laravel offers Blade, a flexible engine that supports template inheritance, components, control structures, data rendering, and more. It allows developers to write concise, readable, reusable, and well-structured view code for modern applications.

In this comprehensive guide, we will explore Blade templates in detail, covering what they are, how they work, and how to use features such as layouts, sections, components, data rendering, loops, conditionals, stacks, includes, slots, template inheritance, and more. This post aims to help you gain a complete understanding of Blade and its role in the Laravel ecosystem.

What Is Blade?

Blade is Laravel’s official templating engine used for writing views. A view is the part of your application responsible for presenting data to the user. Unlike traditional PHP templates, Blade provides additional syntax and functionality that simplifies writing HTML mixed with dynamic content.

Blade is not a standalone template engine; rather, it compiles templates into plain PHP before rendering, which means it does not add extra performance overhead. Templates written in Blade are stored in the resources/views directory and use the .blade.php file extension.


Why Laravel Uses Blade

Laravel values developer experience and clean syntax. Blade allows you to:

  • Write expressive template code without clutter
  • Break down your UI into reusable pieces
  • Manage layouts and sections cleanly
  • Pass data from controllers to views effortlessly
  • Use control structures without writing verbose PHP code
  • Render data securely using escaping features

Blade follows the principle of minimal complexity while providing maximum flexibility, making it suitable for both small websites and large, component-based applications.


How Blade Works Behind the Scenes

When a Blade file is loaded, Laravel compiles it into a cached PHP file stored inside the storage/framework/views directory. This compilation happens only once unless the original Blade file changes. This ensures efficiency because:

  • Blade syntax is converted into pure PHP
  • The compiled templates render quickly
  • No runtime parsing of Blade syntax occurs

This process ensures Blade remains as fast as plain PHP templates.


Blade File Naming and Structure

Blade template files must use the .blade.php file extension. Examples include:

welcome.blade.php
layout.blade.php
home.blade.php
dashboard.blade.php

These files live inside the resources/views directory, and subdirectories follow dot-notation when referenced:

resources/views/posts/index.blade.php

Accessed as:

return view('posts.index');

Displaying Data in Blade Templates

One of the core features of Blade is rendering dynamic data inside a view. Blade offers multiple syntaxes for output.


Basic Output Using Curly Braces

{{ $name }}

The output is automatically escaped to prevent XSS attacks unless otherwise specified. If $name contains HTML, it will be converted to safe text.


Unescaped Output

{!! $htmlContent !!}

Use this carefully, especially with user-generated content.


Displaying Default Values

{{ $title ?? 'Default Title' }}

Displaying Data Using the @{{ }} Literal Escape

This is used when working with JavaScript frameworks like Vue:

@{{ name }}

Blade Layouts and Template Inheritance

One of the most powerful features of Blade is template inheritance. You can define a layout file and extend it in other views. This keeps your code clean and reusable.


Creating a Layout File

Example master layout resources/views/layouts/app.blade.php:

<!DOCTYPE html>
<html>
<head>
&lt;title&gt;@yield('title')&lt;/title&gt;
</head> <body> <div class="container">
@yield('content')
</div> </body> </html>

This layout defines two sections: title and content.


Extending a Layout

@extends('layouts.app')

@section('title', 'Home Page')

@section('content')
&lt;h1&gt;Welcome to the Home Page&lt;/h1&gt;
@endsection

Using @extends, you inherit the layout and define specific sections for each page.


Blade Sections and Yields

Blade sections allow you to inject content into pre-defined layout areas.


Defining a Section in a Child View

@section('content')
<p>This is the content section.</p>
@endsection

Yielding the Section in a Layout

@yield('content')

Shorthand for Simple Sections

@section('title', 'Dashboard')

Blade Includes

Blade’s @include directive allows you to reuse small view pieces like headers, footers, navbars, alerts, or form parts.

@include('partials.header')
@include('partials.footer')
@include('partials.alert', ['type' => 'success'])

Reusable partial templates help avoid repetition.


Blade Components

Components are reusable building blocks used extensively in Laravel for clean, consistent UI. Laravel provides both class-based and anonymous components.


Creating a Component

php artisan make:component Alert

This creates:

  • A Blade file: resources/views/components/alert.blade.php
  • A class: app/View/Components/Alert.php

Using the Component

<x-alert type="success" message="Operation completed" />

Anonymous Components

Anonymous components don’t require a PHP class.

Example file:

resources/views/components/button.blade.php

Use it as:

<x-button>Save</x-button>

Slots in Blade Components

Slots allow dynamic content to be inserted into components.

<x-layout>
&lt;x-slot:title&gt;Dashboard&lt;/x-slot:title&gt;
Welcome back!
</x-layout>

Inside the component:

<title>{{ $title }}</title>
{{ $slot }}

Blade Control Structures

Blade provides cleaner versions of PHP loops and conditionals.


If Statements

@if($loggedIn)
&lt;p&gt;Welcome back&lt;/p&gt;
@endif
@elseif
@else
@endif

Unless Statement

@unless($isAdmin)
&lt;p&gt;You are not an admin.&lt;/p&gt;
@endunless

Foreach Loop

@foreach($posts as $post)
&lt;h2&gt;{{ $post-&gt;title }}&lt;/h2&gt;
@endforeach

For Loop

@for($i = 0; $i < 10; $i++)
{{ $i }}
@endfor

Forelse Loop (Loop With Empty Handling)

@forelse($records as $record)
&lt;p&gt;{{ $record }}&lt;/p&gt;
@empty
&lt;p&gt;No records found.&lt;/p&gt;
@endforelse

While Loop

@while($count < 5)
{{ $count++ }}
@endwhile

Loop Variables

Inside a loop:

$loop->index
$loop->iteration
$loop->count
$loop->first
$loop->last

Example:

@foreach($items as $item)
@if($loop-&gt;first)
    &lt;h3&gt;First Item&lt;/h3&gt;
@endif
@endforeach

Blade Echoing and Raw PHP


Raw PHP in Blade

@php
$counter = 10;
@endphp

Using PHP Tags

<?php echo $name; ?>

Blade Comments

Blade comments do not appear in the rendered HTML.

{{-- This is a Blade comment --}}

Blade Stacks

Blade stacks allow you to push content to specific sections from different child views.


In Layout

@stack('scripts')

In Child View

@push('scripts')
<script src="/example.js"></script>
@endpush

Blade Includes with Data

You can pass extra variables into includes:

@include('partials.card', ['title' => 'Example Title'])

Inside the included view:

<h2>{{ $title }}</h2>

Conditional Class and Attribute Merging

Blade has modern attribute merging features, useful for components.

<button {{ $attributes->merge(['class' => 'btn']) }}>
Click Me
</button>

Child component usage:

<x-button class="btn-primary"/>

Blade merges classes automatically.


Blade and Localization

Laravel supports localization using the lang directory. Blade helps render language strings:

{{ __('messages.welcome') }}

Blade and Loops with Empty States

The @forelse directive simplifies loop handling when no data exists.

@forelse($tasks as $task)
&lt;p&gt;{{ $task }}&lt;/p&gt;
@empty
&lt;p&gt;No tasks available.&lt;/p&gt;
@endforelse

Blade Extending With @includeWhen and @includeIf


Include If Condition Exists

@includeIf('admin.panel')

Conditional Include

@includeWhen($loggedIn, 'partials.user')

Include Unless

@includeUnless($isBanned, 'partials.welcome')

Blade and JSON Encoding

{{ Js::from($array) }}

This produces safe JSON for front-end scripts.


Blade Security


Escape Output by Default

{{ $input }}

Escapes HTML to prevent XSS.


Unescaped

{!! $input !!}

Must be used responsibly.


Blade File Organization Best Practices

  • Keep layouts in resources/views/layouts
  • Keep partials in resources/views/partials
  • Group related views in subfolders
  • Use components instead of duplicate code
  • Use slots for flexible sections
  • Follow proper naming conventions

Example of a Complete Blade Structure

Folder structure:

resources/views/
layouts/
    app.blade.php
components/
    alert.blade.php
    button.blade.php
partials/
    header.blade.php
    footer.blade.php
pages/
    home.blade.php
    contact.blade.php

Each piece works together for a clean architecture.


Real Example Using Layouts, Components, and Control Structures

Layout:

<!DOCTYPE html>
<html>
<head>
&lt;title&gt;@yield('title')&lt;/title&gt;
</head> <body> @include('partials.header') <div class="main">
@yield('content')
</div> @include('partials.footer') </body> </html>

Page:

@extends('layouts.app')

@section('title', 'Posts Page')

@section('content')
&lt;h1&gt;All Posts&lt;/h1&gt;
@forelse($posts as $post)
    &lt;x-card :title="$post-&gt;title"&gt;
        {{ $post-&gt;body }}
    &lt;/x-card&gt;
@empty
    &lt;p&gt;No posts yet.&lt;/p&gt;
@endforelse
@endsection
