Installation

You can install the package via composer:

composer require subit-io/laravel-expo-notifications

If you are using Laravel 5.5 or higher this package will automatically register itself using Package Discovery. For older versions of Laravel you must install the service provider manually:

// config/app.php
'providers' => [
    ...
    NotificationChannels\ExpoPushNotifications\ExpoPushNotificationsServiceProvider::class,
],

Before publish exponent notification migration you must add in .env file:

EXPONENT_PUSH_NOTIFICATION_RECIPIENTS_STORAGE_DRIVER=database

You can publish the migration with:

php artisan vendor:publish --provider="NotificationChannels\ExpoPushNotifications\ExpoPushNotificationsServiceProvider" --tag="migrations"

After publishing the migration you can create the expo_notification_recipients table by running the migrations:

php artisan migrate

You can optionally publish the config file with:

php artisan vendor:publish --provider="NotificationChannels\ExpoPushNotifications\ExpoPushNotificationsServiceProvider" --tag="config"

This is the contents of the published config file:

return [
    'recipients' => [
        /*
         * Supported: "database"
         */
        'driver' => env('EXPONENT_PUSH_NOTIFICATION_RECIPIENTS_STORAGE_DRIVER', 'file'),

        'database' => [
            'table_name' => 'expo_notification_recipients',
        ],
    ]
];

Managing Recipients

This package registers two endpoints that handle the subscription of recipients, the endpoints are defined in src/Http/routes.php file, used by ExpoController and all loaded through the package service provider.

Routing a message

By default the expo "recipient" messages will be sent to will be defined (besides the id) using the notifiable class as type, for example App\User. However, you can change this behaviour by including a routeNotificationForExpoPushNotifications() in the notifiable class method that returns the recipient type.
