Laravel 5.8.17 Released With a “Tappable” Trait

The Laravel team released Laravel 5.8.17 yesterday with a new Tappable trait, a dumpHeaders test method, and quite a few other new features.

First, a new dumpHeaders() method was added to the TestResponse class which helps you debug headers. Here’s the improvement over doing this manually:

$response = $this->get('/example');

// Previously
dd($response->headers->all());

// Ah, that's better
$response->dumpHeaders();

The new dumpHeaders method PR mentioned the dump() method, which you might not be familiar with but is also convenient:

// dd() the response content...
$response->dump();

Next, an ends_with validation rule was added, which looks like this:

$rules = [
    'email' => 'required|ends_with:laravel.com,jasonmccreary.me',
];

Next, support for multiple columns arguments got added to the route:list command:

# Previously
php artisan route:list --columns=method --columns=uri --columns=name

# Now
php artisan route:list --columns=method,uri,name
php artisan route:list --columns=method --columns=uri,name

A new Tappable trait was added to Illuminate\Support which you can define on a class like so:

use Illuminate\Support\Traits\Tappable;

class TappableClass {
    use Tappable;
    // ...
}

Here’s a before and after example:

// with tap method
$result = tap(TappableClass::make(), function ($tappable) {
    $tappable->doSomething();
    $tappable->doSomethingElse();
})->getResult();

// with Tappable trait
$result = TappableClass::make()->tap(function ($tappable) {
    $tappable->doSomething();
    $tappable->doSomethingElse();
})->getResult();
