How to schedule Artisan commands in a package?

Question

I have a package that contains Artisan commands. I’ve registered these commands with Artisan via my service provider like so:

/**
 * Register the application services.
 *
 * @return void
 */
public function register()
{
    // Register Amazon Artisan commands
    $this->commands([
        'App\Marketplace\Amazon\Console\PostProductData',
        'App\Marketplace\Amazon\Console\PostProductImages',
        'App\Marketplace\Amazon\Console\PostProductInventory',
        'App\Marketplace\Amazon\Console\PostProductPricing',
    ]);
}

However, these commands need to be scheduled to run daily.

I know in app/Console/Kernel.php there is the schedule() method where you can register commands and their frequency, but how can I schedule commands in my package’s service provider instead?

Answer 1

It took a lot of debugging and reading through Laravel's source to figure this out, but it turned out to be pretty simple. The trick is to wait until after the Application has booted to schedule the commands, since that is when Laravel defines the Schedule instance and then schedules commands internally. Hope this saves someone a few hours of painful debugging!

use Illuminate\Support\ServiceProvider;
use Illuminate\Console\Scheduling\Schedule;

class ScheduleServiceProvider extends ServiceProvider
{
    public function boot()
    {
        $this->app->booted(function () {
            $schedule = $this->app->make(Schedule::class);
            $schedule->command('some:command')->everyMinute();
        });
    }

    public function register()
    {
    }
}

In Laravel 6.10 and above:

use Illuminate\Support\ServiceProvider;
use Illuminate\Console\Scheduling\Schedule;

class ScheduleServiceProvider extends ServiceProvider
{
    public function boot()
    {
        $this->callAfterResolving(Schedule::class, function (Schedule $schedule) {
            $schedule->command('some:command')->everyMinute();
        });
    }

    public function register()
    {
    }
}
