Laravel Jetstream

Laravel Jetstream is a beautifully designed application scaffolding for Laravel. Jetstream provides the perfect starting point for your next project and includes login, registration, email verification, two-factor authentication, session management, API support via Laravel Sanctum, and optional team management. Laravel Jetstream replaces and improves upon the legacy authentication UI scaffolding available for previous versions of Laravel.

Models Directory

By overwhelming community demand, the default Laravel application skeleton now contains an app/Models directory. We hope you enjoy this new home for your Eloquent models! All relevant generator commands have been updated to assume models exist within the app/Models directory if it exists. If the directory does not exist, the framework will assume your models should be placed within the app directory.

Model Factory Classes

<?php

namespace Database\Factories;

use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;

class UserFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = User::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'name' => $this->faker->name,
            'email' => $this->faker->unique()->safeEmail,
            'email_verified_at' => now(),
            'password' => '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', // password
            'remember_token' => Str::random(10),
        ];
    }
}

use App\Models\User;

User::factory()->count(50)->create();

Migration Squashing

php artisan schema:dump

// Dump the current database schema and prune all existing migrations...
php artisan schema:dump --prune

Job Batching

use App\Jobs\ProcessPodcast;
use App\Podcast;
use Illuminate\Bus\Batch;
use Illuminate\Support\Facades\Bus;
use Throwable;

$batch = Bus::batch([
    new ProcessPodcast(Podcast::find(1)),
    new ProcessPodcast(Podcast::find(2)),
    new ProcessPodcast(Podcast::find(3)),
    new ProcessPodcast(Podcast::find(4)),
    new ProcessPodcast(Podcast::find(5)),
])->then(function (Batch $batch) {
    // All jobs completed successfully...
})->catch(function (Batch $batch, Throwable $e) {
    // First batch job failure detected...
})->finally(function (Batch $batch) {
    // The batch has finished executing...
})->dispatch();

return $batch->id;

Improved Rate Limiting

use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Support\Facades\RateLimiter;

RateLimiter::for('global', function (Request $request) {
    return Limit::perMinute(1000);
});

RateLimiter::for('uploads', function (Request $request) {
    return $request->user()->vipCustomer()
                ? Limit::none()
                : Limit::perMinute(100);
});

Improved Maintenance Mode

php artisan down --secret="1630542a-246b-4b66-afa1-dd72a4c43515"

https://example.com/1630542a-246b-4b66-afa1-dd72a4c43515

Pre-Rendering The Maintenance Mode View

php artisan down --render="errors::503"

Closure Dispatch / Chain `catch`

use Throwable;

dispatch(function () use ($podcast) {
    $podcast->publish();
})->catch(function (Throwable $e) {
    // This job has failed...
});

Dynamic Blade Components

<x-dynamic-component :component="$componentName" class="mt-4" />

Event Listener Improvements

use App\Events\PodcastProcessed;
use Illuminate\Support\Facades\Event;

Event::listen(function (PodcastProcessed $event) {
    //
});

use App\Events\PodcastProcessed;
use function Illuminate\Events\queueable;
use Illuminate\Support\Facades\Event;

Event::listen(queueable(function (PodcastProcessed $event) {
    //
}));

Event::listen(queueable(function (PodcastProcessed $event) {
    //
})->onConnection('redis')->onQueue('podcasts')->delay(now()->addSeconds(10)));

use App\Events\PodcastProcessed;
use function Illuminate\Events\queueable;
use Illuminate\Support\Facades\Event;
use Throwable;

Event::listen(queueable(function (PodcastProcessed $event) {
    //
})->catch(function (PodcastProcessed $event, Throwable $e) {
    // The queued listener failed...
}));

Time Testing Helpers

public function testTimeCanBeManipulated()
{
    // Travel into the future...
    $this->travel(5)->milliseconds();
    $this->travel(5)->seconds();
    $this->travel(5)->minutes();
    $this->travel(5)->hours();
    $this->travel(5)->days();
    $this->travel(5)->weeks();
    $this->travel(5)->years();

    // Travel into the past...
    $this->travel(-5)->hours();

    // Travel to an explicit time...
    $this->travelTo(now()->subHours(6));

    // Return back to the present time...
    $this->travelBack();
}

Artisan `serve` Improvements

The Artisan serve command has been improved with automatic reloading when environment variable changes are detected within your local .env file. Previously, the command had to be manually stopped and restarted.

Tailwind Pagination Views

The Laravel paginator has been updated to use the Tailwind CSS framework by default. Tailwind CSS is a highly customizable, low-level CSS framework that gives you all of the building blocks you need to build bespoke designs without any annoying opinionated styles you have to fight to override. Of course, Bootstrap 3 and 4 views remain available as well.

Routing Namespace Updates

use App\Http\Controllers\UserController;

Route::get('/users', [UserController::class, 'index']);

action([UserController::class, 'index']);

return Redirect::action([UserController::class, 'index']);
