LaraHooks

A lightweight, modular hook engine for Laravel that enables extensibility in both backend processes and Blade templates. Create flexible, plugin-like architectures with minimal overhead.

Based on esemve/Hook by Bence Kádár.

Features

• 🎯 Simple Hook Registration - Register listeners with priorities
• 🔄 Blade Directives - Use @shook for inserting content and @hook/@endhook for wrapping/modifying content
• 🎨 Content Modification - Wrap and modify HTML sections
• 🧪 Testing Support - Mock hooks for easy testing
• 📊 Hook Discovery - List all registered and available hooks

Installation

composer require realzone22/larahooks

Publish the configuration file (optional):

php artisan vendor:publish --tag="larahooks-config"

Basic Usage

Backend Hooks

Register a hook listener in your AppServiceProvider:

use RealZone22\LaraHooks\Facades\LaraHooks;

public function boot(): void
{
    LaraHooks::listen('user.created', function ($callback, $output, $params) {
        $user = $params['user'];
        // Send welcome email, create profile, etc.
    }, 10);
}

Execute the hook in your code:

use RealZone22\LaraHooks\Facades\LaraHooks;

$user = User::create($data);

LaraHooks::get('user.created', ['user' => $user]);

Blade Template Hooks

Insertion Points with @shook

Use @shook to define insertion points where content can be injected:

<div class="header">
    <h1>Welcome</h1>
    
    @shook('header.notifications')
</div>

<div class="sidebar">
    @shook('sidebar.widgets')
</div>

Inject content at these points:

LaraHooks::listen('header.notifications', function ($callback, $output, $params) {
    return '<div class="notification">New messages!</div>';
}, 10);

LaraHooks::listen('sidebar.widgets', function ($callback, $output, $params) {
    return '<div class="weather-widget">Weather Widget</div>';
}, 10);

Content Wrapping with @hook/@endhook

Use @hook and @endhook to wrap content that can be modified or replaced:

@hook('product.card')
    <div class="product">
        <h3>{{ $product->name }}</h3>
        <p>{{ $product->price }}</p>
    </div>
@endhook

@hook('footer.content')
    <div class="default-footer">
        <p>&copy; 2024 Company Name</p>
    </div>
@endhook

Modify or replace the wrapped content:

LaraHooks::listen('product.card', function ($callback, $output, $params) {
    // Wrap existing content with additional markup
    return '<div class="featured-badge">Featured</div>' . $output;
}, 10);

LaraHooks::listen('footer.content', function ($callback, $output, $params) {
    // Replace entire content
    return '<div class="custom-footer"><p>Custom Footer Content</p></div>';
}, 10);

Advanced Usage

Hook Priorities

Lower numbers execute first:

LaraHooks::listen('user.login', function () {
    // Runs first
}, 1);

LaraHooks::listen('user.login', function () {
    // Runs second
}, 10);

LaraHooks::listen('user.login', function () {
    // Runs third
}, 100);

Insertion hooks (@shook) append listener results by default, including when multiple listeners use different or the same priority. To replace all listeners currently registered for a hook and replace the output, pass true as the fourth argument:

LaraHooks::listen('user.login', function () {
    // Replaces all previously registered user.login listeners
}, 10, true);

Stopping Hook Execution

LaraHooks::listen('payment.process', function ($callback, $output, $params) {
    if ($params['amount'] > 1000) {
        LaraHooks::stop('payment.process');
        return 'Payment requires manual review';
    }
}, 1);

LaraHooks::listen('payment.process', function ($callback, $output, $params) {
    // This will not run if the amount > 1000
    return 'Payment processed successfully';
}, 10);

Default Callbacks

Provide a fallback when no hooks are registered:

$content = LaraHooks::get('custom.content', [], function () {
    return 'Default content when no hooks registered';
});

Passing Parameters

LaraHooks::get('order.created', [
    'order' => $order,
    'user' => $user,
    'total' => $total
]);

Access parameters in listeners:

LaraHooks::listen('order.created', function ($callback, $output, $params) {
    $order = $params['order'];
    $user = $params['user'];
    $total = $params['total'];

    // Process order...
}, 10);

Combining @shook and @hook

You can combine both directives for maximum flexibility:

<div class="page-content">
    @shook('content.before')
    
    @hook('main.content')
        <article>
            <h1>{{ $title }}</h1>
            <p>{{ $content }}</p>
        </article>
    @endhook
    
    @shook('content.after')
</div>

Register listeners:

// Insert content before main content
LaraHooks::listen('content.before', function ($callback, $output, $params) {
    return '<div class="breadcrumbs">Home > Article</div>';
}, 10);

// Wrap main content
LaraHooks::listen('main.content', function ($callback, $output, $params) {
    return '<div class="content-wrapper">' . $output . '</div>';
}, 10);

// Insert content after main content
LaraHooks::listen('content.after', function ($callback, $output, $params) {
    return '<div class="related-articles">Related Articles</div>';
}, 10);

Testing

Mock hooks in your tests:

use RealZone22\LaraHooks\Facades\LaraHooks;

public function test_user_creation_with_hooks(): void
{
    LaraHooks::mock('user.created', 'mocked response');

    $result = LaraHooks::get('user.created', ['user' => $user]);

    $this->assertEquals('mocked response', $result);
}

Run the test suite:

composer test

Hook Discovery

List all registered hooks and their locations:

php artisan hook:list

This command shows:

• All registered hook listeners with priorities
• Hooks found in Blade templates (@hook/@endhook, @shook)
• Hooks called in PHP classes (LaraHooks::get())

Use Cases

Plugin System

// In a plugin's service provider
LaraHooks::listen('admin.menu', function ($callback, $output, $params) {
    return $output . '<li><a href="/plugin">My Plugin</a></li>';
}, 50);

Theme Customization

{{-- Base theme template --}}
@hook('footer.widgets')
    <div class="default-footer-widgets">
        <div class="widget">Default Widget</div>
    </div>
@endhook

// In child theme service provider
LaraHooks::listen('footer.widgets', function ($callback, $output, $params) {
    return '<div class="custom-footer-widgets">Custom Widgets</div>';
}, 10);

Dynamic Content Injection

{{-- Template with injection point --}}
<div class="dashboard">
    <h1>Dashboard</h1>
    
    @shook('dashboard.widgets')
</div>

// Multiple plugins can inject widgets
LaraHooks::listen('dashboard.widgets', function ($callback, $output, $params) {
    return '<div class="analytics-widget">Analytics</div>';
}, 10);

LaraHooks::listen('dashboard.widgets', function ($callback, $output, $params) {
    return $output . '<div class="stats-widget">Statistics</div>';
}, 20);

Event-Driven Architecture

LaraHooks::listen('invoice.paid', function ($callback, $output, $params) {
    // Update accounting system
}, 10);

LaraHooks::listen('invoice.paid', function ($callback, $output, $params) {
    // Send receipt email
}, 20);

LaraHooks::listen('invoice.paid', function ($callback, $output, $params) {
    // Update analytics
}, 30);
