 Conditionally running or modifying checks
=========================================

###  On this page

1. [ Custom condition methods ](#content-custom-condition-methods)
2. [ Chaining conditions ](#content-chaining-conditions)
3. [ Modifying checks on a condition ](#content-modifying-checks-on-a-condition)

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()),
]);
```

> **Important!**
> Be cautious when conditionally running or modifying checks. By default, skipped checks are considered failures, which may impact the overall health status. You can adjust this behavior by setting the configuration option `treat_skipped_as_failure` to `false` in the health config file.

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;

Check::macro('ifEnvironment', fn (string|array $envs) => $this->if(fn () => app()->environment($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)
        ),
]);
```
