## Basic Routing
The most basic Laravel routes accept a URI and a closure, providing a very
simple and expressive method of defining routes and behavior without
complicated routing configuration files:
1use Illuminate\Support\Facades\Route;
2 
3Route::get('/greeting', function () {
4 return 'Hello World';
5});
use Illuminate\Support\Facades\Route;
Route::get('/greeting', function () {
return 'Hello World';
});
### The Default Route Files
All Laravel routes are defined in your route files, which are located in the
`routes` directory. These files are automatically loaded by Laravel using the
configuration specified in your application's `bootstrap/app.php` file. The
`routes/web.php` file defines routes that are for your web interface. These
routes are assigned the `web` [middleware
group](/docs/12.x/middleware#laravels-default-middleware-groups), which
provides features like session state and CSRF protection.
For most applications, you will begin by defining routes in your
`routes/web.php` file. The routes defined in `routes/web.php` may be accessed
by entering the defined route's URL in your browser. For example, you may
access the following route by navigating to `http://example.com/user` in your
browser:
1use App\Http\Controllers\UserController;
2 
3Route::get('/user', [UserController::class, 'index']);
use App\Http\Controllers\UserController;
Route::get('/user', [UserController::class, 'index']);
#### API Routes
If your application will also offer a stateless API, you may enable API
routing using the `install:api` Artisan command:
1php artisan install:api
php artisan install:api
The `install:api` command installs [Laravel Sanctum](/docs/12.x/sanctum),
which provides a robust, yet simple API token authentication guard which can
be used to authenticate third-party API consumers, SPAs, or mobile
applications. In addition, the `install:api` command creates the
`routes/api.php` file:
1Route::get('/user', function (Request $request) {
2 return $request->user();
3})->middleware('auth:sanctum');
Route::get('/user', function (Request $request) {
return $request->user();
})->middleware('auth:sanctum');
The routes in `routes/api.php` are stateless and are assigned to the `api`
[middleware group](/docs/12.x/middleware#laravels-default-middleware-groups).
Additionally, the `/api` URI prefix is automatically applied to these routes,
so you do not need to manually apply it to every route in the file. You may
change the prefix by modifying your application's `bootstrap/app.php` file:
1->withRouting(
2 api: __DIR__.'/../routes/api.php',
3 apiPrefix: 'api/admin',
4 // ...
5)
->withRouting(
api: __DIR__.'/../routes/api.php',
apiPrefix: 'api/admin',
// ...
)
#### Available Router Methods
The router allows you to register routes that respond to any HTTP verb:
1Route::get($uri, $callback);
2Route::post($uri, $callback);
3Route::put($uri, $callback);
4Route::patch($uri, $callback);
5Route::delete($uri, $callback);
6Route::options($uri, $callback);
Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);
Sometimes you may need to register a route that responds to multiple HTTP
verbs. You may do so using the `match` method. Or, you may even register a
route that responds to all HTTP verbs using the `any` method:
1Route::match(['get', 'post'], '/', function () {
2 // ...
3});
4 
5Route::any('/', function () {
6 // ...
7});
Route::match(['get', 'post'], '/', function () {
// ...
});
Route::any('/', function () {
// ...
});
When defining multiple routes that share the same URI, routes using the `get`,
`post`, `put`, `patch`, `delete`, and `options` methods should be defined
before routes using the `any`, `match`, and `redirect` methods. This ensures
the incoming request is matched with the correct route.
#### Dependency Injection
You may type-hint any dependencies required by your route in your route's
callback signature. The declared dependencies will automatically be resolved
and injected into the callback by the Laravel [service
container](/docs/12.x/container). For example, you may type-hint the
`Illuminate\Http\Request` class to have the current HTTP request automatically
injected into your route callback:
1use Illuminate\Http\Request;
2 
3Route::get('/users', function (Request $request) {
4 // ...
5});
use Illuminate\Http\Request;
Route::get('/users', function (Request $request) {
// ...
});
#### CSRF Protection
Remember, any HTML forms pointing to `POST`, `PUT`, `PATCH`, or `DELETE`
routes that are defined in the `web` routes file should include a CSRF token
field. Otherwise, the request will be rejected. You can read more about CSRF
protection in the [CSRF documentation](/docs/12.x/csrf):
1<form method="POST" action="/profile">
2 @csrf
3 ...
4</form>
<form method="POST" action="/profile">
@csrf
...
</form>
### Redirect Routes
If you are defining a route that redirects to another URI, you may use the
`Route::redirect` method. This method provides a convenient shortcut so that
you do not have to define a full route or controller for performing a simple
redirect:
1Route::redirect('/here', '/there');
Route::redirect('/here', '/there');
By default, `Route::redirect` returns a `302` status code. You may customize
the status code using the optional third parameter:
1Route::redirect('/here', '/there', 301);
Route::redirect('/here', '/there', 301);
Or, you may use the `Route::permanentRedirect` method to return a `301` status
code:
1Route::permanentRedirect('/here', '/there');
Route::permanentRedirect('/here', '/there');
When using route parameters in redirect routes, the following parameters are
reserved by Laravel and cannot be used: `destination` and `status`.
### View Routes
If your route only needs to return a [view](/docs/12.x/views), you may use the
`Route::view` method. Like the `redirect` method, this method provides a
simple shortcut so that you do not have to define a full route or controller.
The `view` method accepts a URI as its first argument and a view name as its
second argument. In addition, you may provide an array of data to pass to the
view as an optional third argument:
1Route::view('/welcome', 'welcome');
2 
3Route::view('/welcome', 'welcome', ['name' => 'Taylor']);
Route::view('/welcome', 'welcome');
Route::view('/welcome', 'welcome', ['name' => 'Taylor']);
When using route parameters in view routes, the following parameters are
reserved by Laravel and cannot be used: `view`, `data`, `status`, and
`headers`.
### Listing Your Routes
The `route:list` Artisan command can easily provide an overview of all of the
routes that are defined by your application:
1php artisan route:list
php artisan route:list
By default, the route middleware that are assigned to each route will not be
displayed in the `route:list` output; however, you can instruct Laravel to
display the route middleware and middleware group names by adding the `-v`
option to the command:
1php artisan route:list -v
2 
3# Expand middleware groups...
4php artisan route:list -vv
php artisan route:list -v
# Expand middleware groups...
php artisan route:list -vv
You may also instruct Laravel to only show routes that begin with a given URI:
1php artisan route:list --path=api
php artisan route:list --path=api
In addition, you may instruct Laravel to hide any routes that are defined by
third-party packages by providing the `--except-vendor` option when executing
the `route:list` command:
1php artisan route:list --except-vendor
php artisan route:list --except-vendor
Likewise, you may also instruct Laravel to only show routes that are defined
by third-party packages by providing the `--only-vendor` option when executing
the `route:list` command:
1php artisan route:list --only-vendor
php artisan route:list --only-vendor
### Routing Customization
By default, your application's routes are configured and loaded by the
`bootstrap/app.php` file:
1<?php
2 
3use Illuminate\Foundation\Application;
4 
5return Application::configure(basePath: dirname(__DIR__))
6 ->withRouting(
7 web: __DIR__.'/../routes/web.php',
8 commands: __DIR__.'/../routes/console.php',
9 health: '/up',
10 )->create();
<?php
use Illuminate\Foundation\Application;
return Application::configure(basePath: dirname(__DIR__))
->withRouting(
web: __DIR__.'/../routes/web.php',
commands: __DIR__.'/../routes/console.php',
health: '/up',
)->create();
However, sometimes you may want to define an entirely new file to contain a
subset of your application's routes. To accomplish this, you may provide a
`then` closure to the `withRouting` method. Within this closure, you may
register any additional routes that are necessary for your application:
1use Illuminate\Support\Facades\Route;
2 
3->withRouting(
4 web: __DIR__.'/../routes/web.php',
5 commands: __DIR__.'/../routes/console.php',
6 health: '/up',
7 then: function () {
8 Route::middleware('api')
9 ->prefix('webhooks')
10 ->name('webhooks.')
11 ->group(base_path('routes/webhooks.php'));
12 },
13)
use Illuminate\Support\Facades\Route;
->withRouting(
web: __DIR__.'/../routes/web.php',
commands: __DIR__.'/../routes/console.php',
health: '/up',
then: function () {
Route::middleware('api')
->prefix('webhooks')
->name('webhooks.')
->group(base_path('routes/webhooks.php'));
},
)
Or, you may even take complete control over route registration by providing a
`using` closure to the `withRouting` method. When this argument is passed, no
HTTP routes will be registered by the framework and you are responsible for
manually registering all routes:
1use Illuminate\Support\Facades\Route;
2 
3->withRouting(
4 commands: __DIR__.'/../routes/console.php',
5 using: function () {
6 Route::middleware('api')
7 ->prefix('api')
8 ->group(base_path('routes/api.php'));
9 
10 Route::middleware('web')
11 ->group(base_path('routes/web.php'));
12 },
13)
use Illuminate\Support\Facades\Route;
->withRouting(
commands: __DIR__.'/../routes/console.php',
using: function () {
Route::middleware('api')
->prefix('api')
->group(base_path('routes/api.php'));
Route::middleware('web')
->group(base_path('routes/web.php'));
},
)
## Route Parameters
### Required Parameters
Sometimes you will need to capture segments of the URI within your route. For
example, you may need to capture a user's ID from the URL. You may do so by
defining route parameters:
1Route::get('/user/{id}', function (string $id) {
2 return 'User '.$id;
3});
Route::get('/user/{id}', function (string $id) {
return 'User '.$id;
});
You may define as many route parameters as required by your route:
1Route::get('/posts/{post}/comments/{comment}', function (string $postId, string $commentId) {
2 // ...
3});
Route::get('/posts/{post}/comments/{comment}', function (string $postId, string $commentId) {
// ...
});
Route parameters are always encased within `{}` braces and should consist of
alphabetic characters. Underscores (`_`) are also acceptable within route
parameter names. Route parameters are injected into route callbacks /
controllers based on their order - the names of the route callback /
controller arguments do not matter.
#### Parameters and Dependency Injection
If your route has dependencies that you would like the Laravel service
container to automatically inject into your route's callback, you should list
your route parameters after your dependencies:
1use Illuminate\Http\Request;
2 
3Route::get('/user/{id}', function (Request $request, string $id) {
4 return 'User '.$id;
5});
use Illuminate\Http\Request;
Route::get('/user/{id}', function (Request $request, string $id) {
return 'User '.$id;
});
### Optional Parameters
Occasionally you may need to specify a route parameter that may not always be
present in the URI. You may do so by placing a `?` mark after the parameter
name. Make sure to give the route's corresponding variable a default value:
1Route::get('/user/{name?}', function (?string $name = null) {
2 return $name;
3});
4 
5Route::get('/user/{name?}', function (?string $name = 'John') {
6 return $name;
7});
Route::get('/user/{name?}', function (?string $name = null) {
return $name;
});
Route::get('/user/{name?}', function (?string $name = 'John') {
return $name;
});
### Regular Expression Constraints
You may constrain the format of your route parameters using the `where` method
on a route instance. The `where` method accepts the name of the parameter and
a regular expression defining how the parameter should be constrained:
1Route::get('/user/{name}', function (string $name) {
2 // ...
3})->where('name', '[A-Za-z]+');
4 
5Route::get('/user/{id}', function (string $id) {
6 // ...
7})->where('id', '[0-9]+');
8 
9Route::get('/user/{id}/{name}', function (string $id, string $name) {
10 // ...
11})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);
Route::get('/user/{name}', function (string $name) {
// ...
})->where('name', '[A-Za-z]+');
Route::get('/user/{id}', function (string $id) {
// ...
})->where('id', '[0-9]+');
Route::get('/user/{id}/{name}', function (string $id, string $name) {
// ...
})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);
For convenience, some commonly used regular expression patterns have helper
methods that allow you to quickly add pattern constraints to your routes:
1Route::get('/user/{id}/{name}', function (string $id, string $name) {
2 // ...
3})->whereNumber('id')->whereAlpha('name');
4 
5Route::get('/user/{name}', function (string $name) {
6 // ...
7})->whereAlphaNumeric('name');
8 
9Route::get('/user/{id}', function (string $id) {
10 // ...
11})->whereUuid('id');
12 
13Route::get('/user/{id}', function (string $id) {
14 // ...
15})->whereUlid('id');
16 
17Route::get('/category/{category}', function (string $category) {
18 // ...
19})->whereIn('category', ['movie', 'song', 'painting']);
20 
21Route::get('/category/{category}', function (string $category) {
22 // ...
23})->whereIn('category', CategoryEnum::cases());
Route::get('/user/{id}/{name}', function (string $id, string $name) {
// ...
})->whereNumber('id')->whereAlpha('name');
Route::get('/user/{name}', function (string $name) {
// ...
})->whereAlphaNumeric('name');
Route::get('/user/{id}', function (string $id) {
// ...
})->whereUuid('id');
Route::get('/user/{id}', function (string $id) {
// ...
})->whereUlid('id');
Route::get('/category/{category}', function (string $category) {
// ...
})->whereIn('category', ['movie', 'song', 'painting']);
Route::get('/category/{category}', function (string $category) {
// ...
})->whereIn('category', CategoryEnum::cases());
If the incoming request does not match the route pattern constraints, a 404
HTTP response will be returned.
#### Global Constraints
If you would like a route parameter to always be constrained by a given
regular expression, you may use the `pattern` method. You should define these
patterns in the `boot` method of your application's
`App\Providers\AppServiceProvider` class:
1use Illuminate\Support\Facades\Route;
2 
3/**
4 * Bootstrap any application services.
5 */
6public function boot(): void
7{
8 Route::pattern('id', '[0-9]+');
9}
use Illuminate\Support\Facades\Route;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Route::pattern('id', '[0-9]+');
}
Once the pattern has been defined, it is automatically applied to all routes
using that parameter name:
1Route::get('/user/{id}', function (string $id) {
2 // Only executed if {id} is numeric...
3});
Route::get('/user/{id}', function (string $id) {
// Only executed if {id} is numeric...
});
#### Encoded Forward Slashes
The Laravel routing component allows all characters except `/` to be present
within route parameter values. You must explicitly allow `/` to be part of
your placeholder using a `where` condition regular expression:
1Route::get('/search/{search}', function (string $search) {
2 return $search;
3})->where('search', '.*');
Route::get('/search/{search}', function (string $search) {
return $search;
})->where('search', '.*');
Encoded forward slashes are only supported within the last route segment.
## Named Routes
Named routes allow the convenient generation of URLs or redirects for specific
routes. You may specify a name for a route by chaining the `name` method onto
the route definition:
1Route::get('/user/profile', function () {
2 // ...
3})->name('profile');
Route::get('/user/profile', function () {
// ...
})->name('profile');
You may also specify route names for controller actions:
1Route::get(
2 '/user/profile',
3 [UserProfileController::class, 'show']
4)->name('profile');
Route::get(
'/user/profile',
[UserProfileController::class, 'show']
)->name('profile');
Route names should always be unique.
#### Generating URLs to Named Routes
Once you have assigned a name to a given route, you may use the route's name
when generating URLs or redirects via Laravel's `route` and `redirect` helper
functions:
1// Generating URLs...
2$url = route('profile');
3 
4// Generating Redirects...
5return redirect()->route('profile');
6 
7return to_route('profile');
// Generating URLs...
$url = route('profile');
// Generating Redirects...
return redirect()->route('profile');
return to_route('profile');
If the named route defines parameters, you may pass the parameters as the
second argument to the `route` function. The given parameters will
automatically be inserted into the generated URL in their correct positions:
1Route::get('/user/{id}/profile', function (string $id) {
2 // ...
3})->name('profile');
4 
5$url = route('profile', ['id' => 1]);
Route::get('/user/{id}/profile', function (string $id) {
// ...
})->name('profile');
$url = route('profile', ['id' => 1]);
If you pass additional parameters in the array, those key / value pairs will
automatically be added to the generated URL's query string:
1Route::get('/user/{id}/profile', function (string $id) {
2 // ...
3})->name('profile');
4 
5$url = route('profile', ['id' => 1, 'photos' => 'yes']);
6 
7// /user/1/profile?photos=yes
Route::get('/user/{id}/profile', function (string $id) {
// ...
})->name('profile');
$url = route('profile', ['id' => 1, 'photos' => 'yes']);
// /user/1/profile?photos=yes
Sometimes, you may wish to specify request-wide default values for URL
parameters, such as the current locale. To accomplish this, you may use the
[URL::defaults method](/docs/12.x/urls#default-values).
#### Inspecting the Current Route
If you would like to determine if the current request was routed to a given
named route, you may use the `named` method on a Route instance. For example,
you may check the current route name from a route middleware:
1use Closure;
2use Illuminate\Http\Request;
3use Symfony\Component\HttpFoundation\Response;
4 
5/**
6 * Handle an incoming request.
7 *
8 * @param \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response) $next
9 */
10public function handle(Request $request, Closure $next): Response
11{
12 if ($request->route()->named('profile')) {
13 // ...
14 }
15 
16 return $next($request);
17}
use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
/**
* Handle an incoming request.
*
* @param \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response) $next
*/
public function handle(Request $request, Closure $next): Response
{
if ($request->route()->named('profile')) {
// ...
}
return $next($request);
}
## Route Groups
Route groups allow you to share route attributes, such as middleware, across a
large number of routes without needing to define those attributes on each
individual route.
Nested groups attempt to intelligently "merge" attributes with their parent
group. Middleware and `where` conditions are merged while names and prefixes
are appended. Namespace delimiters and slashes in URI prefixes are
automatically added where appropriate.
### Middleware
To assign [middleware](/docs/12.x/middleware) to all routes within a group,
you may use the `middleware` method before defining the group. Middleware are
executed in the order they are listed in the array:
1Route::middleware(['first', 'second'])->group(function () {
2 Route::get('/', function () {
3 // Uses first & second middleware...
4 });
5 
6 Route::get('/user/profile', function () {
7 // Uses first & second middleware...
8 });
9});
Route::middleware(['first', 'second'])->group(function () {
Route::get('/', function () {
// Uses first & second middleware...
});
Route::get('/user/profile', function () {
// Uses first & second middleware...
});
});
### Controllers
If a group of routes all utilize the same
[controller](/docs/12.x/controllers), you may use the `controller` method to
define the common controller for all of the routes within the group. Then,
when defining the routes, you only need to provide the controller method that
they invoke:
1use App\Http\Controllers\OrderController;
2 
3Route::controller(OrderController::class)->group(function () {
4 Route::get('/orders/{id}', 'show');
5 Route::post('/orders', 'store');
6});
use App\Http\Controllers\OrderController;
Route::controller(OrderController::class)->group(function () {
Route::get('/orders/{id}', 'show');
Route::post('/orders', 'store');
});
### Subdomain Routing
Route groups may also be used to handle subdomain routing. Subdomains may be
assigned route parameters just like route URIs, allowing you to capture a
portion of the subdomain for usage in your route or controller. The subdomain
may be specified by calling the `domain` method before defining the group:
1Route::domain('{account}.example.com')->group(function () {
2 Route::get('/user/{id}', function (string $account, string $id) {
3 // ...
4 });
5});
Route::domain('{account}.example.com')->group(function () {
Route::get('/user/{id}', function (string $account, string $id) {
// ...
});
});
In order to ensure your subdomain routes are reachable, you should register
subdomain routes before registering root domain routes. This will prevent root
domain routes from overwriting subdomain routes which have the same URI path.
### Route Prefixes
The `prefix` method may be used to prefix each route in the group with a given
URI. For example, you may want to prefix all route URIs within the group with
`admin`:
1Route::prefix('admin')->group(function () {
2 Route::get('/users', function () {
3 // Matches The "/admin/users" URL
4 });
5});
Route::prefix('admin')->group(function () {
Route::get('/users', function () {
// Matches The "/admin/users" URL
});
});
### Route Name Prefixes
The `name` method may be used to prefix each route name in the group with a
given string. For example, you may want to prefix the names of all of the
routes in the group with `admin`. The given string is prefixed to the route
name exactly as it is specified, so we will be sure to provide the trailing
`.` character in the prefix:
1Route::name('admin.')->group(function () {
2 Route::get('/users', function () {
3 // Route assigned name "admin.users"...
4 })->name('users');
5});
Route::name('admin.')->group(function () {
Route::get('/users', function () {
// Route assigned name "admin.users"...
})->name('users');
});
## Route Model Binding
When injecting a model ID to a route or controller action, you will often
query the database to retrieve the model that corresponds to that ID. Laravel
route model binding provides a convenient way to automatically inject the
model instances directly into your routes. For example, instead of injecting a
user's ID, you can inject the entire `User` model instance that matches the
given ID.
### Implicit Binding
Laravel automatically resolves Eloquent models defined in routes or controller
actions whose type-hinted variable names match a route segment name. For
example:
1use App\Models\User;
2 
3Route::get('/users/{user}', function (User $user) {
4 return $user->email;
5});
use App\Models\User;
Route::get('/users/{user}', function (User $user) {
return $user->email;
});
Since the `$user` variable is type-hinted as the `App\Models\User` Eloquent
model and the variable name matches the `{user}` URI segment, Laravel will
automatically inject the model instance that has an ID matching the
corresponding value from the request URI. If a matching model instance is not
found in the database, a 404 HTTP response will automatically be generated.
Of course, implicit binding is also possible when using controller methods.
Again, note the `{user}` URI segment matches the `$user` variable in the
controller which contains an `App\Models\User` type-hint:
1use App\Http\Controllers\UserController;
2use App\Models\User;
3 
4// Route definition...
5Route::get('/users/{user}', [UserController::class, 'show']);
6 
7// Controller method definition...
8public function show(User $user)
9{
10 return view('user.profile', ['user' => $user]);
11}
use App\Http\Controllers\UserController;
use App\Models\User;
// Route definition...
Route::get('/users/{user}', [UserController::class, 'show']);
// Controller method definition...
public function show(User $user)
{
return view('user.profile', ['user' => $user]);
}
#### Soft Deleted Models
Typically, implicit model binding will not retrieve models that have been
[soft deleted](/docs/12.x/eloquent#soft-deleting). However, you may instruct
the implicit binding to retrieve these models by chaining the `withTrashed`
method onto your route's definition:
1use App\Models\User;
2 
3Route::get('/users/{user}', function (User $user) {
4 return $user->email;
5})->withTrashed();
use App\Models\User;
Route::get('/users/{user}', function (User $user) {
return $user->email;
})->withTrashed();
#### Customizing the Key
Sometimes you may wish to resolve Eloquent models using a column other than
`id`. To do so, you may specify the column in the route parameter definition:
1use App\Models\Post;
2 
3Route::get('/posts/{post:slug}', function (Post $post) {
4 return $post;
5});
use App\Models\Post;
Route::get('/posts/{post:slug}', function (Post $post) {
return $post;
});
If you would like model binding to always use a database column other than
`id` when retrieving a given model class, you may override the
`getRouteKeyName` method on the Eloquent model:
1/**
2 * Get the route key for the model.
3 */
4public function getRouteKeyName(): string
5{
6 return 'slug';
7}
/**
* Get the route key for the model.
*/
public function getRouteKeyName(): string
{
return 'slug';
}
#### Custom Keys and Scoping
When implicitly binding multiple Eloquent models in a single route definition,
you may wish to scope the second Eloquent model such that it must be a child
of the previous Eloquent model. For example, consider this route definition
that retrieves a blog post by slug for a specific user:
1use App\Models\Post;
2use App\Models\User;
3 
4Route::get('/users/{user}/posts/{post:slug}', function (User $user, Post $post) {
5 return $post;
6});
use App\Models\Post;
use App\Models\User;
Route::get('/users/{user}/posts/{post:slug}', function (User $user, Post $post) {
return $post;
});
When using a custom keyed implicit binding as a nested route parameter,
Laravel will automatically scope the query to retrieve the nested model by its
parent using conventions to guess the relationship name on the parent. In this
case, it will be assumed that the `User` model has a relationship named
`posts` (the plural form of the route parameter name) which can be used to
retrieve the `Post` model.
If you wish, you may instruct Laravel to scope "child" bindings even when a
custom key is not provided. To do so, you may invoke the `scopeBindings`
method when defining your route:
1use App\Models\Post;
2use App\Models\User;
3 
4Route::get('/users/{user}/posts/{post}', function (User $user, Post $post) {
5 return $post;
6})->scopeBindings();
use App\Models\Post;
use App\Models\User;
Route::get('/users/{user}/posts/{post}', function (User $user, Post $post) {
return $post;
})->scopeBindings();
Or, you may instruct an entire group of route definitions to use scoped
bindings:
1Route::scopeBindings()->group(function () {
2 Route::get('/users/{user}/posts/{post}', function (User $user, Post $post) {
3 return $post;
4 });
5});
Route::scopeBindings()->group(function () {
Route::get('/users/{user}/posts/{post}', function (User $user, Post $post) {
return $post;
});
});
Similarly, you may explicitly instruct Laravel to not scope bindings by
invoking the `withoutScopedBindings` method:
1Route::get('/users/{user}/posts/{post:slug}', function (User $user, Post $post) {
2 return $post;
3})->withoutScopedBindings();
Route::get('/users/{user}/posts/{post:slug}', function (User $user, Post $post) {
return $post;
})->withoutScopedBindings();
#### Customizing Missing Model Behavior
Typically, a 404 HTTP response will be generated if an implicitly bound model
is not found. However, you may customize this behavior by calling the
`missing` method when defining your route. The `missing` method accepts a
closure that will be invoked if an implicitly bound model cannot be found:
1use App\Http\Controllers\LocationsController;
2use Illuminate\Http\Request;
3use Illuminate\Support\Facades\Redirect;
4 
5Route::get('/locations/{location:slug}', [LocationsController::class, 'show'])
6 ->name('locations.view')
7 ->missing(function (Request $request) {
8 return Redirect::route('locations.index');
9 });
use App\Http\Controllers\LocationsController;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Redirect;
Route::get('/locations/{location:slug}', [LocationsController::class, 'show'])
->name('locations.view')
->missing(function (Request $request) {
return Redirect::route('locations.index');
});
### Implicit Enum Binding
PHP 8.1 introduced support for
[Enums](https://www.php.net/manual/en/language.enumerations.backed.php). To
complement this feature, Laravel allows you to type-hint a [string-backed
Enum](https://www.php.net/manual/en/language.enumerations.backed.php) on your
route definition and Laravel will only invoke the route if that route segment
corresponds to a valid Enum value. Otherwise, a 404 HTTP response will be
returned automatically. For example, given the following Enum:
1<?php
2 
3namespace App\Enums;
4 
5enum Category: string
6{
7 case Fruits = 'fruits';
8 case People = 'people';
9}
<?php
namespace App\Enums;
enum Category: string
{
case Fruits = 'fruits';
case People = 'people';
}
You may define a route that will only be invoked if the `{category}` route
segment is `fruits` or `people`. Otherwise, Laravel will return a 404 HTTP
response:
1use App\Enums\Category;
2use Illuminate\Support\Facades\Route;
3 
4Route::get('/categories/{category}', function (Category $category) {
5 return $category->value;
6});
use App\Enums\Category;
use Illuminate\Support\Facades\Route;
Route::get('/categories/{category}', function (Category $category) {
return $category->value;
});
### Explicit Binding
You are not required to use Laravel's implicit, convention based model
resolution in order to use model binding. You can also explicitly define how
route parameters correspond to models. To register an explicit binding, use
the router's `model` method to specify the class for a given parameter. You
should define your explicit model bindings at the beginning of the `boot`
method of your `AppServiceProvider` class:
1use App\Models\User;
2use Illuminate\Support\Facades\Route;
3 
4/**
5 * Bootstrap any application services.
6 */
7public function boot(): void
8{
9 Route::model('user', User::class);
10}
use App\Models\User;
use Illuminate\Support\Facades\Route;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Route::model('user', User::class);
}
Next, define a route that contains a `{user}` parameter:
1use App\Models\User;
2 
3Route::get('/users/{user}', function (User $user) {
4 // ...
5});
use App\Models\User;
Route::get('/users/{user}', function (User $user) {
// ...
});
Since we have bound all `{user}` parameters to the `App\Models\User` model, an
instance of that class will be injected into the route. So, for example, a
request to `users/1` will inject the `User` instance from the database which
has an ID of `1`.
If a matching model instance is not found in the database, a 404 HTTP response
will be automatically generated.
#### Customizing the Resolution Logic
If you wish to define your own model binding resolution logic, you may use the
`Route::bind` method. The closure you pass to the `bind` method will receive
the value of the URI segment and should return the instance of the class that
should be injected into the route. Again, this customization should take place
in the `boot` method of your application's `AppServiceProvider`:
1use App\Models\User;
2use Illuminate\Support\Facades\Route;
3 
4/**
5 * Bootstrap any application services.
6 */
7public function boot(): void
8{
9 Route::bind('user', function (string $value) {
10 return User::where('name', $value)->firstOrFail();
11 });
12}
use App\Models\User;
use Illuminate\Support\Facades\Route;
/**
* Bootstrap any application services.
*/
public function boot(): void
{
Route::bind('user', function (string $value) {
return User::where('name', $value)->firstOrFail();
});
}
Alternatively, you may override the `resolveRouteBinding` method on your
Eloquent model. This method will receive the value of the URI segment and
should return the instance of the class that should be injected into the
route:
1/**
2 * Retrieve the model for a bound value.
3 *
4 * @param mixed $value
5 * @param string|null $field
6 * @return \Illuminate\Database\Eloquent\Model|null
7 */
8public function resolveRouteBinding($value, $field = null)
9{
10 return $this->where('name', $value)->firstOrFail();
11}
/**
* Retrieve the model for a bound value.
*
* @param mixed $value
* @param string|null $field
* @return \Illuminate\Database\Eloquent\Model|null
*/
public function resolveRouteBinding($value, $field = null)
{
return $this->where('name', $value)->firstOrFail();
}
If a route is utilizing implicit binding scoping, the
`resolveChildRouteBinding` method will be used to resolve the child binding of
the parent model:
1/**
2 * Retrieve the child model for a bound value.
3 *
4 * @param string $childType
5 * @param mixed $value
6 * @param string|null $field
7 * @return \Illuminate\Database\Eloquent\Model|null
8 */
9public function resolveChildRouteBinding($childType, $value, $field)
10{
11 return parent::resolveChildRouteBinding($childType, $value, $field);
12}
/**
* Retrieve the child model for a bound value.
*
* @param string $childType
* @param mixed $value
* @param string|null $field
* @return \Illuminate\Database\Eloquent\Model|null
*/
public function resolveChildRouteBinding($childType, $value, $field)
{
return parent::resolveChildRouteBinding($childType, $value, $field);
}
## Fallback Routes
Using the `Route::fallback` method, you may define a route that will be
executed when no other route matches the incoming request. Typically,
unhandled requests will automatically render a "404" page via your
application's exception handler. However, since you would typically define the
`fallback` route within your `routes/web.php` file, all middleware in the
`web` middleware group will apply to the route. You are free to add additional
middleware to this route as needed:
1Route::fallback(function () {
2 // ...
3});
Route::fallback(function () {
// ...
});
## Rate Limiting
### Defining Rate Limiters
Laravel includes powerful and customizable rate limiting services that you may
utilize to restrict the amount of traffic for a given route or group of
routes. To get started, you should define rate limiter configurations that
meet your application's needs.
Rate limiters may be defined within the `boot` method of your application's
`App\Providers\AppServiceProvider` class:
1use Illuminate\Cache\RateLimiting\Limit;
2use Illuminate\Http\Request;
3use Illuminate\Support\Facades\RateLimiter;
4 
5/**
6 * Bootstrap any application services.
7 */
8protected function boot(): void
9{
10 RateLimiter::for('api', function (Request $request) {
11 return Limit::perMinute(60)->by($request->user()?->id ?: $request->ip());
12 });
13}
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
/**
* Bootstrap any application services.
*/
protected function boot(): void
{
RateLimiter::for('api', function (Request $request) {
return Limit::perMinute(60)->by($request->user()?->id ?: $request->ip());
});
}
Rate limiters are defined using the `RateLimiter` facade's `for` method. The
`for` method accepts a rate limiter name and a closure that returns the limit
configuration that should apply to routes that are assigned to the rate
limiter. Limit configuration are instances of the
`Illuminate\Cache\RateLimiting\Limit` class. This class contains helpful
"builder" methods so that you can quickly define your limit. The rate limiter
name may be any string you wish:
1use Illuminate\Cache\RateLimiting\Limit;
2use Illuminate\Http\Request;
3use Illuminate\Support\Facades\RateLimiter;
4 
5/**
6 * Bootstrap any application services.
7 */
8protected function boot(): void
9{
10 RateLimiter::for('global', function (Request $request) {
11 return Limit::perMinute(1000);
12 });
13}
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
/**
* Bootstrap any application services.
*/
protected function boot(): void
{
RateLimiter::for('global', function (Request $request) {
return Limit::perMinute(1000);
});
}
If the incoming request exceeds the specified rate limit, a response with a
429 HTTP status code will automatically be returned by Laravel. If you would
like to define your own response that should be returned by a rate limit, you
may use the `response` method:
1RateLimiter::for('global', function (Request $request) {
2 return Limit::perMinute(1000)->response(function (Request $request, array $headers) {
3 return response('Custom response...', 429, $headers);
4 });
5});
RateLimiter::for('global', function (Request $request) {
return Limit::perMinute(1000)->response(function (Request $request, array $headers) {
return response('Custom response...', 429, $headers);
});
});
Since rate limiter callbacks receive the incoming HTTP request instance, you
may build the appropriate rate limit dynamically based on the incoming request
or authenticated user:
1RateLimiter::for('uploads', function (Request $request) {
2 return $request->user()->vipCustomer()
3 ? Limit::none()
4 : Limit::perHour(10);
5});
RateLimiter::for('uploads', function (Request $request) {
return $request->user()->vipCustomer()
? Limit::none()
: Limit::perHour(10);
});
#### Segmenting Rate Limits
Sometimes you may wish to segment rate limits by some arbitrary value. For
example, you may wish to allow users to access a given route 100 times per
minute per IP address. To accomplish this, you may use the `by` method when
building your rate limit:
1RateLimiter::for('uploads', function (Request $request) {
2 return $request->user()->vipCustomer()
3 ? Limit::none()
4 : Limit::perMinute(100)->by($request->ip());
5});
RateLimiter::for('uploads', function (Request $request) {
return $request->user()->vipCustomer()
? Limit::none()
: Limit::perMinute(100)->by($request->ip());
});
To illustrate this feature using another example, we can limit access to the
route to 100 times per minute per authenticated user ID or 10 times per minute
per IP address for guests:
1RateLimiter::for('uploads', function (Request $request) {
2 return $request->user()
3 ? Limit::perMinute(100)->by($request->user()->id)
4 : Limit::perMinute(10)->by($request->ip());
5});
RateLimiter::for('uploads', function (Request $request) {
return $request->user()
? Limit::perMinute(100)->by($request->user()->id)
: Limit::perMinute(10)->by($request->ip());
});
#### Multiple Rate Limits
If needed, you may return an array of rate limits for a given rate limiter
configuration. Each rate limit will be evaluated for the route based on the
order they are placed within the array:
1RateLimiter::for('login', function (Request $request) {
2 return [
3 Limit::perMinute(500),
4 Limit::perMinute(3)->by($request->input('email')),
5 ];
6});
RateLimiter::for('login', function (Request $request) {
return [
Limit::perMinute(500),
Limit::perMinute(3)->by($request->input('email')),
];
});
If you're assigning multiple rate limits segmented by identical `by` values,
you should ensure that each `by` value is unique. The easiest way to achieve
this is to prefix the values given to the `by` method:
1RateLimiter::for('uploads', function (Request $request) {
2 return [
3 Limit::perMinute(10)->by('minute:'.$request->user()->id),
4 Limit::perDay(1000)->by('day:'.$request->user()->id),
5 ];
6});
RateLimiter::for('uploads', function (Request $request) {
return [
Limit::perMinute(10)->by('minute:'.$request->user()->id),
Limit::perDay(1000)->by('day:'.$request->user()->id),
];
});
### Attaching Rate Limiters to Routes
Rate limiters may be attached to routes or route groups using the `throttle`
[middleware](/docs/12.x/middleware). The throttle middleware accepts the name
of the rate limiter you wish to assign to the route:
1Route::middleware(['throttle:uploads'])->group(function () {
2 Route::post('/audio', function () {
3 // ...
4 });
5 
6 Route::post('/video', function () {
7 // ...
8 });
9});
Route::middleware(['throttle:uploads'])->group(function () {
Route::post('/audio', function () {
// ...
});
Route::post('/video', function () {
// ...
});
});
#### Throttling With Redis
By default, the `throttle` middleware is mapped to the
`Illuminate\Routing\Middleware\ThrottleRequests` class. However, if you are
using Redis as your application's cache driver, you may wish to instruct
Laravel to use Redis to manage rate limiting. To do so, you should use the
`throttleWithRedis` method in your application's `bootstrap/app.php` file.
This method maps the `throttle` middleware to the
`Illuminate\Routing\Middleware\ThrottleRequestsWithRedis` middleware class:
1->withMiddleware(function (Middleware $middleware) {
2 $middleware->throttleWithRedis();
3 // ...
4})
->withMiddleware(function (Middleware $middleware) {
$middleware->throttleWithRedis();
// ...
})
## Form Method Spoofing
HTML forms do not support `PUT`, `PATCH`, or `DELETE` actions. So, when
defining `PUT`, `PATCH`, or `DELETE` routes that are called from an HTML form,
you will need to add a hidden `_method` field to the form. The value sent with
the `_method` field will be used as the HTTP request method:
1<form action="/example" method="POST">
2 <input type="hidden" name="_method" value="PUT">
3 <input type="hidden" name="_token" value="{{ csrf_token() }}">
4</form>
<form action="/example" method="POST">
<input type="hidden" name="_method" value="PUT">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
</form>
For convenience, you may use the `@method` [Blade directive](/docs/12.x/blade)
to generate the `_method` input field:
1<form action="/example" method="POST">
2 @method('PUT')
3 @csrf
4</form>
<form action="/example" method="POST">
@method('PUT')
@csrf
</form>
## Accessing the Current Route
You may use the `current`, `currentRouteName`, and `currentRouteAction`
methods on the `Route` facade to access information about the route handling
the incoming request:
1use Illuminate\Support\Facades\Route;
2 
3$route = Route::current(); // Illuminate\Routing\Route
4$name = Route::currentRouteName(); // string
5$action = Route::currentRouteAction(); // string
use Illuminate\Support\Facades\Route;
$route = Route::current(); // Illuminate\Routing\Route
$name = Route::currentRouteName(); // string
$action = Route::currentRouteAction(); // string
You may refer to the API documentation for both the [underlying class of the
Route
facade](https://api.laravel.com/docs/12.x/Illuminate/Routing/Router.html) and
[Route
instance](https://api.laravel.com/docs/12.x/Illuminate/Routing/Route.html) to
review all of the methods that are available on the router and route classes.
## Cross-Origin Resource Sharing (CORS)
Laravel can automatically respond to CORS `OPTIONS` HTTP requests with values
that you configure. The `OPTIONS` requests will automatically be handled by
the `HandleCors` [middleware](/docs/12.x/middleware) that is automatically
included in your application's global middleware stack.
Sometimes, you may need to customize the CORS configuration values for your
application. You may do so by publishing the `cors` configuration file using
the `config:publish` Artisan command:
1php artisan config:publish cors
php artisan config:publish cors
This command will place a `cors.php` configuration file within your
application's `config` directory.
For more information on CORS and CORS headers, please consult the [MDN web
documentation on CORS](https://developer.mozilla.org/en-
US/docs/Web/HTTP/CORS#The_HTTP_response_headers).
## Route Caching
When deploying your application to production, you should take advantage of
Laravel's route cache. Using the route cache will drastically decrease the
amount of time it takes to register all of your application's routes. To
generate a route cache, execute the `route:cache` Artisan command:
1php artisan route:cache
php artisan route:cache
After running this command, your cached routes file will be loaded on every
request. Remember, if you add any new routes you will need to generate a fresh
route cache. Because of this, you should only run the `route:cache` command
during your project's deployment.
You may use the `route:clear` command to clear the route cache:
1php artisan route:clear
php artisan route:clear
