Let's discover these features.

 

Controller Route Group

From laravel 9 we can use common routes as controller group routes which will make route defining more easy and readable. Let's take a look at what it looks like.

use App\Http\Controllers\PostController;
 
Route::controller(PostController::class)->group(function () {
    Route::get('/posts/{id}', 'show');
    Route::post('/posts', 'store');
});

 

The server.php file

The server.php file used for php artisan serve. From laravel 9, it will be removed from the root of the project. This will be included from the inside of the framework.

 

Inline Blade Templating

With laravel 9, we can convert any blade template string to valid HTML tags easily with the help of an inline blade template. Here an example is given below.

use Illuminate\Support\Facades\Blade;
 
return Blade::render('Hi, {{$name}}', ['name' => 'Jhon']);

 

Flysystem 3.x

In Laravel 9, the storage facade will use the Flysystem 3.

 

Anonymous Stub Migrations

To prevent migration class name collisions we can use anonymous stub migration features in laravel 9. Laravel 9 will use this feature as default for the command php artisan make:migration

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
 
return new class extends Migration {

    public function up()
    {
        Schema::table('people', function (Blueprint $table) {
            $table->string('name')->nullable();
        });
    }
};

 

Accessors / Mutators Improvement

From laravel 9, we can easily define eloquent model accessors and mutators every easily with sort syntax which is a very intuitive syntax.

 

Before laravel 9

public function getNameAttribute($value)
{
    return strtoupper($value);
}
 
public function setNameAttribute($value)
{
    $this->attributes['name'] = $value;
}

In laravel 9

use Illuminate\Database\Eloquent\Casts\Attribute;
 
public function name(): Attribute
{
    return new Attribute(
        get: fn ($value) => strtoupper($value),
        set: fn ($value) => $value,
    );
}

 

Enum Eloquent Attribute Casting

Like an as eloquent date, number and other types. Now we can cast eloquent attributes to Enum.

use App\Enums\PostStatus;

protected $casts = [
    'status' => PostStatus::class,
];

 

Full-Text Indexes

In a table definition, we can use full-text indexes in laravel 9.

$table->text('bio')->fullText();

In query

DB::table('users')
    ->whereFullText('bio', 'developer')
    ->get();

 

Checked / Selected Blade Directives

Making checked box checked/unchecked, select box selected state. Now you can use the blade directive.

<input type="checkbox"
        @checked(old('active', $user->active))
        name="active"/>

<select name="user_id">
    @foreach ($users as $row)
        <option value="{{ $row->id }}" @selected(old('id') == $row->id)>
            {{ $row->name }}
        </option>
    @endforeach
</select>

 

Enums Implicit Route Binding

enum Category: string
{
    case Fruits = 'fruits';
    case People = 'people';
}

Route::get('/categories/{category}', function (Category $category) {
    return $category->value;
});

 

SwiftMailer to Symfony Mailer

Laravel 9 will be moved from SwiftMailer to Symfony Mailer. Here is the upgrade guide from SwiftMailer to Symfony Mailer.

 

Pagination - Bootstrap 5

Laravel 9 included bootstrap 5 pagination view. To use bootstrap 5 pagination view add this line in your app service provider inside the boot method.

use Illuminate\Pagination\Paginator;

public function boot()
{
    Paginator::useBootstrapFive();
}

 

Functions and New Helpers

The \Illuminate\Support\Str facade will use PHP 8 string function internally for str_contains, str_starts_with and str_ends_with

Helper

str('Laravel')->append(' Article');
// 'Laravel Article'

str()->snake('LaravelArticle');
//laravel_article

//HTTP redirect to a name route
return to_route('posts.show', ['post' => 1]);

 

Query Builder Interface

Laravel 9 introduce a new query builder interface.

return Model::query()
	->whereNotExists(function($query) {
		// $query is a Query\Builder
	})
	->whereHas('relation', function($query) {
		// $query is an Eloquent\Builder
	})
	->with('relation', function($query) {
		// $query is an Eloquent\Relation
	});

 

New route list design

Laravel 9 comes with a beautiful route list design in CLI with colour highlighted HTTP verb. We'll see the defined route list with the command php artisan route:list




New Test Coverage

A new test coverage option was added in Laravel 9. You will get the test coverage by artisan command
artisan test --coverage. Here is the sample output.
