README

An Unleash client for Laravel.

Installation

composer require mikefrancis/laravel-unleash

Export package config:

php artisan vendor:publish --provider="MikeFrancis\LaravelUnleash\ServiceProvider"

Configuration

Documentation for configuration can be found in config/unleash.php.

Usage

use \MikeFrancis\LaravelUnleash\Unleash;

$unleash = app(Unleash::class);

if ($unleash->isFeatureEnabled('myAwesomeFeature')) {
  // Congratulations, you can see this awesome feature!
}

if ($unleash->isFeatureDisabled('myAwesomeFeature')) {
  // Check back later for more features!
}

$feature = $unleash->getFeature('myAwesomeFeature');

$allFeatures = $unleash->getFeatures();

Facades

You can use the Unleash facade:

use Unleash;

if (Unleash::isFeatureEnabled('myAwesomeFeature')) {
  // Congratulations, you can see this awesome feature!
}

if (Unleash::isFeatureDisabled('myAwesomeFeature')) {
  // Check back later for more features!
}

$feature = Unleash::getFeature('myAwesomeFeature');

$allFeatures = Unleash::getFeatures();

or use the generically named Feature facade:

use Feature;

if (Feature::enabled('myAwesomeFeature')) {
  // Congratulations, you can see this awesome feature!
}

if (Feature::disabled('myAwesomeFeature')) {
  // Check back later for more features!
}

$feature = Feature::get('myAwesomeFeature');

$allFeatures = Feature::all();

Dynamic Arguments

If your strategy relies on dynamic data at runtime, you can pass additional arguments to the feature check functions:

use \MikeFrancis\LaravelUnleash\Unleash;
use Config;

$unleash = app(Unleash::class);

$allowList = config('app.allow_list');

if ($unleash->isFeatureEnabled('myAwesomeFeature', $allowList)) {
  // Congratulations, you can see this awesome feature!
}

if ($unleash->isFeatureDisabled('myAwesomeFeature', $allowList)) {
  // Check back later for more features!
}

Blade

Blade directive for checking if a feature is enabled:

@featureEnabled('myAwesomeFeature')
Congratulations, you can see this awesome feature!
@endfeatureEnabled

Or if a feature is disabled:

@featureDisabled('myAwesomeFeature')
Check back later for more features!
@endfeatureDisabled

You cannot currently use dynamic strategy arguments with Blade template directives.

Middleware

This package includes middleware that will deny routes depending on whether a feature is enabled or not.

To use the middle, add the following to your app/Http/Kernel.php:

protected $routeMiddleware = [
    // other middleware
    'feature.enabled' => \MikeFrancis\LaravelUnleash\Middleware\FeatureEnabled::class,
    'feature.disabled' => \MikeFrancis\LaravelUnleash\Middleware\FeatureDisabled::class,
];

You can then use the middleware in your routes:

Route::get('/new-feature-path', function () {
    //
})->middleware('feature.enabled:myAwesomeFeature');

Route::get('/terrible-legacy-path', function () {
    //
})->middleware('feature.disabled:myAwesomeFeature');

or in your controllers like so:

class ExampleController extends Controller
{
    public function __construct()
    {
        $this->middleware('feature.enabled:myAwesomeFeature');
        // or
        $this->middleware('feature.disabled:myAwesomeFeature');
    }
}

You cannot currently use dynamic strategy arguments with Middleware.
