laravel-notification-patterns

Define the channels in the notification's via() method by returning an array like ['mail', 'database', 'broadcast']. Then implement the corresponding toMail(), toArray(), and toBroadcast() methods to format the message for each channel.

Implement the ShouldQueue interface on the notification class and use the Queueable trait. You can assign different queues per channel with viaQueues(), delay delivery per channel, and set afterCommit to dispatch only after database transactions commit.

Yes, use on-demand notifications with Notification::route('mail', 'admin@example.com')->notify(new YourNotification()). This supports mail and Slack routes and allows specifying recipient names without requiring a Notifiable model.

Call Notification::fake() in your test, then use assertions like Notification::assertSentTo(), assertNotSentTo(), and assertSentToTimes() to verify delivery. You can also inspect mail content by calling toMail() directly and asserting on the subject and rendered output.

Implement the shouldSend() method on the notification class, which receives the notifiable and channel name. Return false to skip delivery, for example to respect user email preferences or suppress notifications below a threshold amount.
