New Laravel 11 Apps Include A Health Check Endpoint

As part of the release of Laravel 11, new applications include a health /up endpoint. This route is defined in the new bootstrap/app.php file by passing the health parameter—which is defined by default in the Laravel 11 skeleton:

 Application::configure(basePath: dirname(__DIR__))
     ->withProviders()
     ->withRouting(
         web: __DIR__.'/../routes/web.php',
         // api: __DIR__.'/../routes/api.php',
         commands: __DIR__.'/../routes/console.php',
         // channels: __DIR__.'/../routes/channels.php',
+        health: '/up', 
     )
     // ...

When setting up the application routing, the Laravel framework defines the health route and also emits a DiagnosingHealth event:

use Illuminate\Foundation\Events\DiagnosingHealth;

// ...
if (is_string($health)) {
    Route::middleware('web')->get($health, function () {
        Event::dispatch(new DiagnosingHealth);

        return View::file(__DIR__.'/../resources/health-up.blade.php');
    });
}

The route is configurable with the default /up endpoint and returns an animated “Application up” health page in the browser:
