Bento helps you organize feature launches by custom user segments. Create and organize rules to make features available to certain users.

Define your features, define your segmentation strategies and let Bento launch each feature to the right people. Bento can also help you run A/B testing on your applications.

The core concepts of this library are inspired by Airbnb's Trebuchet project for Ruby.

Installation

Require this package with composer:

composer require eXolnet/laravel-bento

After installing Bento, publish its example service provider to hold your feature definitions:

php artisan vendor:publish --tag=bento-provider

Then, add it to the providers array in config/app.php:

App\Providers\BentoServiceProvider::class

Usage

Create Features

Define features and their launch segmentation strategies. You can define one strategy with the feature method:

Bento::feature('feature')->visitorPercent(10);

Or you can combine multiple strategies:

Bento::feature('feature')->visitorPercent(10)->hostname('example.com');

Your features could be grouped in the boot method of a service provider:

<?php

namespace App\Providers;

use Exolnet\Bento\Facades\Bento;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * @return void
     */
    public function boot(): void
    {
        Bento::feature('foo')->everyone();
        Bento::feature('bar')->everyone();
    }
}

Launch Your Features

You can check if a feature is launched for a visitor with the launch method:

if (Bento::launch('feature')) {
    //
}

Or check that a feature is awaiting launch:

if (Bento::await('feature')) {
    //
}

Blade

In Blade templates, handy macros are also available:

@launch('feature')
    Feature is launched!
@else
    Coming soon!
@endlaunch

@await('feature')
    Coming soon!
@else
    Feature is launched!
@endawait

Middleware

Since some strategy requires the request context to be evaluated, it's recommended to use middleware to limit a route:

Add the following middleware in the $routeMiddleware of your application's HTTP Kernel:

    protected $routeMiddleware = [
        // ...
        'await' => \Exolnet\Bento\Middleware\Await::class,
        'launch' => \Exolnet\Bento\Middleware\Launch::class,
        // ...
    ];

Then, you could use them to restrict your routes:

Route::middleware('launch:feature')->group(function () {
    //
});

Route::middleware('await:feature')->group(function () {
    //
});

Basic Segmentation Strategies

The following segmentation strategies are available to help quickly target your users:

Callback
Config
Date
Environment
Everyone
Guest
Hostname
Nobody
Stub
User (authenticated or specific user IDs)
User Percent (a fraction of all connected visitors)
Visitor Percent (a fraction of all your visitors)

Logic Segmentation Strategies

Additional logic segmentation strategies are available to help target your users with more complex rules.

Not

Bento::feature('feature')->not->everyone();

All

use \Exolnet\Bento\Strategy\AimsStrategies;

Bento::feature('feature')->all(function (AimsStrategies $aims) {
    $aims
        ->environment('production')
        ->visitorPercent(20);
});

Any

use \Exolnet\Bento\Strategy\AimsStrategies;

Bento::feature('feature')->any(function (AimsStrategies $aims) {
    $aims
        ->environment('staging')
        ->user([1, 2]);
});

Custom Segmentation Strategies

You can create custom strategies with dependency injection support similarly to Laravel Controllers' method injection. A common use-case for method injection is injecting the Illuminate\Contracts\Auth\Guard instance into your strategy to target users by property:

Callback

use Illuminate\Contracts\Auth\Guard;

Bento::feature('feature')->custom(function (Guard $guard, $role) {
    return $guard->user() && $guard->user()->role === 'admin';
});

Class

use Illuminate\Contracts\Auth\Guard;

class RoleStrategy {
    /**
     * @var \Illuminate\Contracts\Auth\Guard
     */
    protected $guard;
    
    /**
     * @var string 
     */
    protected $role;

    /**
     * @param \Illuminate\Contracts\Auth\Guard $guard
     */
    public function __construct(Guard $guard, string $role)
    {
        $this->guard = $guard;
        $this->role = $role;
    }

    /**
     * @return bool
     */
    public function launch(): bool
    {
        return $this->guard->user() && $this->guard->user()->role === $this->role;
    }
}

Bento::feature('feature')->aim(RoleStrategy::class, 'admin');

Testing

To run the PHPUnit tests, please use:

$ composer test
