Installation

You can install the package via composer:

composer require oneduo/laravel-pennant-launchdarkly

Usage

You may use the driver in your existing Laravel Pennant configuration file, by setting your store's driver to LaunchDarklyDriver::class.

You should provide your SDK key in your store's configuration.

You may add any LaucnhDarkly cleint specific configuration options to the store's configuration.

A typical configuration might look like this:

// config/pennant.php

<?php

use Oneduo\LaravelPennantLaunchdarkly\LaunchDarklyDriver;

return [

    /*
    |--------------------------------------------------------------------------
    | Default Pennant Store
    |--------------------------------------------------------------------------
    |
    | Here you will specify the default store that Pennant should use when
    | storing and resolving feature flag values. Pennant ships with the
    | ability to store flag values in an in-memory array or database.
    |
    | Supported: "array", "database"
    |
    */

    'default' => env('PENNANT_STORE', 'laucnhdarkly'),

    /*
    |--------------------------------------------------------------------------
    | Pennant Stores
    |--------------------------------------------------------------------------
    |
    | Here you may configure each of the stores that should be available to
    | Pennant. These stores shall be used to store resolved feature flag
    | values - you may configure as many as your application requires.
    |
    */

    'stores' => [
        // ...
        
        'laucnhdarkly' => [
            'driver' => LaunchDarklyDriver::class,
            'sdk_key' => env('LAUNCHDARKLY_SDK_KEY'),
            'options' => [],
        ],
    ],
];

Then, in your scopeable Model, for instance your User model, you should implement the FeatureScopeable interface, and provide a toFeatureIdentifier method.

<?php

namespace App\Models;

use Illuminate\Foundation\Auth\User as Authenticable;
use Laravel\Pennant\Contracts\FeatureScopeable;
use LaunchDarkly\LDUser;
use LaunchDarkly\LDUserBuilder;

class User extends Authenticable implements FeatureScopeable
{
    // ...
    public function toFeatureIdentifier(string $driver): LDUser
    {
        return (new LDUserBuilder($this->getKey()))
        // you may add more attributes to your LDUser
        // ->email($this->email)
        // ->firstName($this->firstname)
        // ->lastName($this->lastname)
        //->custom([...])
        ->build();
    }
}

Troubleshooting

[E1] Scope must be an instance of LDUser

This is most likely due to either the scope you are using, or the fact that your currently authenticated user not having implemented FeatureScopeable correctly.

Please check the usage instructions.

[E2] Not implemented, Launchdarkly driver does not support this method

The LaunchDarkly driver for Laravel Pennant only supports read operations, and does not support write operations. If you need to write to LaunchDarkly, you should use the LaunchDarkly platform or the REST API.

Testing

composer test
