Laravel Observer Pattern Skill

Use this skill when you need to trigger logic based on Eloquent Model events (created, updated, deleted, etc.).

When to use

• Sending emails after user registration.
• Logging changes for audit entry.
• Updating summary tables.

Rules

1. Silent Handling

• Observers should handle exceptions gracefully or let them bubble up depending on criticality.
• Avoid putting slow blocking logic (like API calls) directly in Observer. Dispatch a Job/Event instead.

2. Registration

• Ensure the Observer is registered in the model attribute #[ObservedBy(UserObserver::class)] (Laravel 10+ standard) or in AppServiceProvider.
• Prefer Attributes:

#[ObservedBy(UserObserver::class)]
class User extends Authenticatable
{
    // ...
}

3. Methods

• Type hint the model in the observer methods.

public function created(User $user): void
{
    // ...
}
