Conditionally running or modifying checks

This package provides methods to run certain checks only when specified conditions are met.

If you would like to conditionally run a check, you can use the if and unless methods. For more control, you can also use callables. They are evaluated every time a health check is run.

use Spatie\Health\Facades\Health;
use Spatie\Health\Checks\Checks\DebugModeCheck;
use Spatie\Health\Checks\Checks\RedisCheck;

Health::checks([
    DebugModeCheck::new()->unless(app()->environment('local')),
    RedisCheck::new()->if(fn () => app(SomeHeavyService::class)->shouldCheckHealth()),
]);

##Custom condition methods

You may find yourself repeating conditions for multiple checks. To avoid that, you can register a Laravel macro on a check with a custom condition method.

use Spatie\Health\Facades\Health;
use Spatie\Health\Checks\Check;
use Spatie\Health\Checks\Checks\DebugModeCheck;
use Spatie\Health\Checks\Checks\RedisCheck;

Health::macro('ifEnvironment', fn (string|array $envs) => app()->environment($envs));

Health::checks([
    DebugModeCheck::new()->ifEnvironment('production')
]);

##Chaining conditions

Sometimes you need more than one condition on a check, so you may chain two or more of them simply by calling if or unless multiple times. They are evaluated in the order that you define them.

use Spatie\Health\Facades\Health;
use Spatie\Health\Checks\Checks\DebugModeCheck;
use Spatie\Health\Checks\Checks\RedisCheck;

Health::checks([
    DebugModeCheck::new()
        ->unless(app()->environment('local'))
        ->if(fn () => app(SomeHeavyService::class)->shouldCheckHealth()),
]);

##Modifying checks on a condition

You may want to slightly change check's configuration under a specific condition. You can do so using when and doUnless methods. In this example, a smaller memory limit is enforced on a local environment.

use Spatie\Health\Facades\Health;
use Spatie\Health\Checks\Checks\RedisMemoryUsageCheck;

Health::checks([
    RedisMemoryUsageCheck::new()
        ->failWhenAboveMb(1000)
        ->when(
            app()->environment('local'), 
            fn (RedisMemoryUsageCheck $check) => $check->failWhenAboveMb(200)
        ),
]);
