Installation

For Laravel ~5

composer require collab-corp/laravel-feature-toggle

As with any package, it's a good idea to refresh composer autoloader.

composer dump-autoload

Configuration

To publish features.php config file, run the following, vendor:publish command.

php artisan vendor:publish --provider="\CollabCorp\LaravelFeatureToggle\FeatureToggleServiceProvider"

You may then configure your config to your liking, it is possible to use callbacks or callables strings as values.

Binding callbacks

It can become quite cumbersome with a lot of callbacks in your features config, binding a callback to an alias makes this a breeze.

Feature::bind('evaluation', function ($user, ...$dependencies) {
	// logic.

	return (boolean) $result;
});

In addition to letting laravel inject dependencies through the container, it is also possible to specify values in a comma seperated list.

In your config...

// config/features.php
<?php return [
	// ...
	'my_feature' => 'env:local,development'
];

In your service provider...

Feature::bind('env', function ($user, array $enviroments) {
	return app()->enviroment($enviroments);
});

And you are ready to go.

Usage

This package adds the @features blade directive, it outputs JavaScript that adds the feature function to the window.

it is also possible to check a feature inside a blade file, like so

@feature('name')
	// Feature is enabled
@else
	// Feature is disabled
@endfeature

In your application code you can simply call

 use Feature;

 Feature::isEnabled('name');
 Feature::isDisabled('name');

Evaluating features in JavaScript

To evaluate a feature toggle in your frontend, simply add @features to your blade file. Likely in your header.

This will add a bool feature(value) helper to your window.

Testing

composer test
