Setting service provider

This package provide auto discovery for service provider

If Laravel package auto-discovery is disabled, add service providers manually to /config/app.php. There are service provider you must add:

\Abrouter\LaravelClient\Providers\AbrouterServiceProvider::class

Publish client configuration:

php artisan vendor:publish --tag=abrouter

Configure ABRouter client:

Put your ABRouter token in /config/abrouter.php. You can find this token in ABRouter dashboard.

use Abrouter\LaravelClient\Bridge\KvStorage;
use Abrouter\LaravelClient\Bridge\ParallelRunning\TaskManager;

return [
    'token' => '14da89de1713a74c1ed50aafaff18c24bf372a9913e67e6a7a915def3332a97c9c9ecbe2cd6d3047',
    'host' => 'https://abrouter.com',

        'taskManager' => TaskManager::class,
    ],
    'kvStorage' => KvStorage::class
];

Configure Parallel running

Parallel running is a feature that allows you to run A/B tests asynchronously. It requires ready-to-use Laravel cache (probably by Redis).

This feature enables caching of experiment branches to run the experiment locally, then using Laravel built-in queues to sync the data with ABRouter server. Please make sure, your supervisor config, queues and caching storage is enabled in Laravel to use.

Parallel running allows to run your A/B tests without blocking. Additionally, you can configure it on your own.

🚀 Running A/B tests

use Abrouter\Client\Client;

class ExampleController
{
    public function __invoke(Client $client)
    {
        $userId = auth()->user()->id;
        $buttonColor = $client->experiments()->run($userId, 'button_color');
        return view('button', [
            'color' => $buttonColor->getBranchId(),
        ]);
    }
}

🚀 Running feature flags

use Abrouter\Client\Client;

class ExampleController
{
    public function __invoke(Client $client)
    {
        $isEnabledButton = $client->featureFlags()->run('enabled_button_feature_flag');

        return view('featureFlags', [
            'enabledButtonFeatureFlag' => $isEnabledButton,
        ]);
    }
}

🚀 Sending the stats

use Abrouter\Client\Client;
use Abrouter\Client\Builders\StatEventBuilder;

class ExampleController
{
    public function __invoke(Client $client, StatEventBuilder $statEventBuilder)
    {
        $userId = auth()->user()->id;
        //sending button_click event as button_click+1
        $client->statistics()->sendEvent(
            $eventBuilder
                ->incremental()
                ->event('button_click')
                ->setUserId($userId)
                ->build()
        );
        
        //sending purchase event with purchase amount (+30)
        $client->statistics()->sendEvent(
            $eventBuilder
                ->summarize()
                ->event('purchase')
                ->setValue(30)
                ->setUserId($userId)
                ->build()
        );
    }
}

For additional details of sending events please see StatEventBuilder class.
