Events

Minimize the number of traits

By default, Laravel adds few traits to a new Event class, even if it’s not needed in your particular case. It’s still better to control traits more explicitly.

- use Dispatchable, InteractsWithSockets, SerializesModels;
+ use SerializesModels; // only if the Event will be used with Queued Event Listeners

Explanation:

• Dispatchable is to add static methods to simplify event dispatching, like YourEvent::dispatch(). We do not use this syntax, so we don’t need this trait. Please use \Illuminate\Support\Facades\Event facade instead, e.g. Event::dispatch(new YourEvent()).
• SerializesModels is to gracefully serialize any Eloquent models if the event object contains Eloquent models and going to be serialized using PHP's serialize function, such as when utilizing queued listeners.
• InteractsWithSockets is for broadcasting only, e.g. using Laravel Echo.

Best Practices:

• Tailor Event class traits based on specific needs rather than using the default set.
• Understand the implications of each trait to avoid unnecessary overhead or missing functionality.
• Event class should be final readonly
