Auto register routes using PHP 8 attributes in Laravel

Spatie has introduced a laravel-route-attributes package that provides a way to automatically register the routes utilizing PHP 8 attributes in laravel. This package provides several annotations to automatically register the routes. This package requires the minimum php 8 version. You can view its detailed video by clicking this link.

Here you'll get an introduction to PHP 8 attributes and how these laravel-routes-attributes operate under the hood.

Installation

You can install this package via composer by running this command:

composer require spatie/laravel-route-attributes

Next You've to publish the config file by running this command:

php artisan vendor:publish --provider="Spatie\RouteAttributes\RouteAttributesServiceProvider" --tag="config"

This is the contents of the published config file:

return [
    /*
     *  Automatic registration of routes will only happen if this setting is `true`
     */
    'enabled' => true,

    /*
     * Controllers in these directories that have routing attributes
     * will automatically be registered.
     */
    'directories' => [
        app_path('Http/Controllers'),
    ],
];

Usage

The package provides several annotations that should be put on controller classes and methods. These annotations will be utilized to automatically register routes.

Adding a GET route

use Spatie\RouteAttributes\Attributes\Get;
class MyController
{
    #[Get('my-route')]
    public function myMethod()
    {

    }
}

This attribute will automatically register this route:

Route::get('my-route', [MyController::class, 'myMethod']);

Specify a route name

All HTTP verb attributes accept a parameter named name that accepts a route name.

use Spatie\RouteAttributes\Attributes\Get;
class MyController
{
    #[Get('my-route', name: "my-route-name")]
    public function myMethod()
    {

    }
}

This attribute will automatically register this route:

Route::get('my-route', [MyController::class, 'myMethod'])->name('my-route-name');

Adding middleware

All HTTP verb attributes accept a parameter named middleware that accepts a middleware class or an array of middleware classes.

use Spatie\RouteAttributes\Attributes\Get;
class MyController
{
    #[Get('my-route', middleware: MyMiddleware::class)]
    public function myMethod()
    {

    }
}

This annotation will automatically register this route:

Route::get('my-route', [MyController::class, 'myMethod'])->middleware(MyMiddleware::class);

If you wanted to apply middleware to all methods of a class you can utilize the Middleware attribute. You can mix this with applying attributes to a method.

use Spatie\RouteAttributes\Attributes\Get;
use Spatie\RouteAttributes\Attributes\Middleware;
#[Middleware(MyMiddleware::class)]
class MyController
{
    #[Get('my-route')]
    public function firstMethod()
    {
    }

    #[Get('my-other-route', middleware: MyOtherMiddleware::class)]
    public function secondMethod()
    {
    }
}

These annotations will automatically register these routes:

Route::get('my-route', [MyController::class, 'firstMethod'])->middleware(MyMiddleware::class);
Route::get('my-other-route', [MyController::class, 'secondMethod'])->middleware([MyMiddleware::class, MyOtherMiddleware]);

Specifying a prefix

You can apply the Prefix annotation on a class to prefix the routes of all methods of that class.

use Spatie\RouteAttributes\Attributes\Get;
use Spatie\RouteAttributes\Attributes\Post;
use Spatie\RouteAttributes\Attributes\Prefix;

#[Prefix('my-prefix')]
class MyController
{
    #[Get('my-get-route')]
    public function myGetMethod()
    {
    }

    #[Post('my-post-route')]
    public function myPostMethod()
    {
    }
}

These annotations will automatically register these routes:

Route::get('my-prefix/my-get-route', [MyController::class, 'myGetMethod']);
Route::post('my-prefix/my-post-route', [MyController::class, 'myPostMethod']);

Specifying a domain

You can also utilize the Domain annotation on a class to prefix the routes of all methods of that class.

use Spatie\RouteAttributes\Attributes\Get;
use Spatie\RouteAttributes\Attributes\Post;
use Spatie\RouteAttributes\Attributes\Domain;

#[Domain('my-subdomain.localhost')]
class MyController
{
    #[Get('my-get-route')]
    public function myGetMethod()
    {
    }

    #[Post('my-post-route')]
    public function myPostMethod()
    {
    }
}

These annotations will automatically register these routes:

Route::get('my-get-route', [MyController::class, 'myGetMethod'])->domain('my-subdomain.localhost');
Route::post('my-post-route', [MyController::class, 'myPostMethod'])->domain('my-subdomain.localhost');

Specifying wheres

You can utilize the Where annotation on a class or method to constrain the format of your route parameters.

use Spatie\RouteAttributes\Attributes\Get;
use Spatie\RouteAttributes\Attributes\Post;
use Spatie\RouteAttributes\Attributes\Where;
use Spatie\RouteAttributes\Attributes\WhereAlphaNumeric;
#[Where('my-where', '[0-9]+')]
class MyController
{
    #[Get('my-get-route/{my-where}')]
    public function myGetMethod()
    {
    }

    #[Post('my-post-route/{my-where}/{my-alpha-numeric}')]
    #[WhereAlphaNumeric('my-alpha-numeric')]
    public function myPostMethod()
    {
    }
}

These annotations will automatically register these routes:

Route::get('my-get-route/{my-where}', [MyController::class, 'myGetMethod'])->where(['my-where' => '[0-9]+']);
Route::post('my-post-route/{my-where}/{my-alpha-numeric}', [MyController::class, 'myPostMethod'])->where(['my-where' => '[0-9]+', 'my-alpha-numeric' => '[a-zA-Z0-9]+']);
