In this episode, we're taking the logic we built for checking if a user should be notified that an endpoint is down, and actually turning it into real email notifications!
Here's how we do it: Rather than cramming all the notification logic into one place, we use Laravel events and listeners to keep things neat and reusable. First, we set up an event called EndpointWentDown
. Then, we register a listener called SendDownEmailNotifications
that will fire every time the event is dispatched.
Inside the listener, we loop through all the notification email addresses for the site (not users, just raw email addresses), and send out our notification. Laravel notifications fit perfectly here, so if we want to send messages via SMS or other channels in the future, it's super easy to extend.
We also go over creating the actual email notification, using a custom markdown template, so the notification email looks nice and can be easily personalized with endpoint details.
At the end, we test the whole thing out by simulating endpoint failures and seeing the emails arrive, verifying everything works as expected—and we show it's easy to notify multiple recipients. Thanks to Laravel's notification system, expanding to further notification methods will be a breeze!
