README

A PHP package for ensuring web applications meet accessibility standards, particularly for color contrast.

Features

• Color Contrast Checking: Determine if text colors have sufficient contrast against background colors
• Accessible Text Color Generation: Generate accessible text colors based on background colors
• Color Format Support: Support for hex, Tailwind CSS, rgb(), and hsl() color formats.
• User Accessibility Settings: Manage user preferences for accessibility features
• Laravel Integration: Seamless integration with Laravel applications

Installation

You can install the package via Composer:

composer require artisanpack-ui/accessibility

For detailed installation instructions, including Laravel integration, see the Getting Started Guide.

Usage

Here is a practical, real-world example of how to use the package to create an accessible button component in Laravel.

Creating an Accessible Button Component

1. Create a new Blade component:

php artisan make:component Button

2. Modify the component class:

In app/View/Components/Button.php, we'll accept a background color and automatically determine the correct text color.

// app/View/Components/Button.php

namespace App\View\Components;

use Illuminate\View\Component;

class Button extends Component
{
    public string $bgColor;
    public string $textColor;

    public function __construct(string $bgColor = '#3b82f6')
    {
        $this->bgColor = $bgColor;
        $this->textColor = a11yGetContrastColor($this->bgColor);
    }

    public function render()
    {
        return view('components.button');
    }
}

3. Update the component view:

In resources/views/components/button.blade.php, we'll apply the colors as inline styles.

// resources/views/components/button.blade.php

@props(['bgColor', 'textColor'])

<button {{ $attributes->merge(['class' => 'px-4 py-2 rounded']) }} style="background-color: {{ $bgColor }}; color: {{ $textColor }};">
    {{ $slot }}
</button>

4. Use the component in your views:

Now you can easily create accessible buttons with any background color.

<x-button>Click Me</x-button>

<x-button bg-color="#dc2626">Delete</x-button>

<x-button bg-color="rgb(16, 185, 129)">Success</x-button>

For more detailed examples, including Livewire components and dynamic theming, see the Real-World Examples documentation.

AI features

When artisanpack-ui/ai v1.0+ is installed alongside this package, three AI-powered accessibility agents become available. Each is toggle-able through the shared FeatureRegistry and no-ops when the toggle is off.

Trigger surfaces ship in-package for all three frontends so extending framework support does not require any changes to @artisanpack-ui/react or @artisanpack-ui/vue:

• Livewire — <livewire:a11y-ai-content-analysis />, <livewire:a11y-ai-aria-suggestion />, <livewire:a11y-ai-contrast-explanation />.
• React — TypeScript/TSX components at resources/js/react/ (barrel exports through resources/js/react/index.ts). Copy into your app's asset pipeline or wire directly through your Vite/Webpack config.
• Vue — the same three components as Vue 3 SFCs at resources/js/vue/.

The React and Vue components POST to /api/v1/a11y/ai/{content-analysis,aria-suggestion,contrast-explanation} by default; pass an endpoint prop to override.

The shipped endpoints sit behind auth:sanctum and throttle:api, so a stateful SPA needs Laravel Sanctum's SPA setup: SANCTUM_STATEFUL_DOMAINS configured for the frontend origin, a prior GET to /sanctum/csrf-cookie to seed the XSRF-TOKEN cookie, and same-origin requests. The bundled React and Vue triggers automatically read that cookie and send X-XSRF-TOKEN + X-Requested-With: XMLHttpRequest, so no per-caller header wiring is needed once the SPA is authenticated.

Requirements

• PHP 8.3 or higher
• Laravel 12 or 13 (for Laravel integration)

The PHP floor moved to 8.3 in 2.2.0 to match the artisanpack-ui/ai foundation dependency. Laravel 11 support was dropped in the same release. Users staying on PHP 8.2 or Laravel 11 should pin to ^2.1.2.
