+# Events & Notifications Best Practices
+
+## Rely on Event Discovery
+
+Laravel auto-discovers listeners by reading `handle(EventType $event)` type-hints. No manual registration needed in `AppServiceProvider`.
+
+## Run `event:cache` in Production Deploy
+
+Event discovery scans the filesystem per-request in dev. Cache it in production: `php artisan optimize` or `php artisan event:cache`.
+
+## Use `ShouldDispatchAfterCommit` Inside Transactions
+
+Without it, a queued listener may process before the DB transaction commits, reading data that doesn't exist yet.
+
+```php
+class OrderShipped implements ShouldDispatchAfterCommit {}
+```
+
+## Always Queue Notifications
+
+Notifications often hit external APIs (email, SMS, Slack). Without `ShouldQueue`, they block the HTTP response.
+
+```php
+class InvoicePaid extends Notification implements ShouldQueue
+{
+    use Queueable;
+}
+```
+
+## Use `afterCommit()` on Notifications in Transactions
+
+Same race condition as events — call `afterCommit()` to delay dispatch until the transaction commits.
+
+```php
+$user->notify((new InvoicePaid($invoice))->afterCommit());
+```
+
+## Route Notification Channels to Dedicated Queues
+
+Mail and database notifications have different priorities. Use `viaQueues()` to route them to separate queues.
+
+## Use On-Demand Notifications for Non-User Recipients
+
+Avoid creating dummy models to send notifications to arbitrary addresses.
+
+```php
+Notification::route('mail', 'admin@example.com')->notify(new SystemAlert());
+```
+
+## Implement `HasLocalePreference` on Notifiable Models
+
+Laravel automatically uses the user's preferred locale for all notifications and mailables — no per-call `locale()` needed.
