Target class does not exist in Laravel
======================================

### [\#Laravel](https://rocketeersapp.com/knowledge/laravel)

This error means Laravel cannot resolve a controller or class you referenced in a route or container binding. Almost always a namespace, typo or autoload issue.

[\#](#content-about-the-error "Permalink")About the error
---------------------------------------------------------

The message looks like:

 ```
Illuminate\Contracts\Container\BindingResolutionException:
Target class [App\Http\Controllers\UserController] does not exist.

```

Laravel's service container tried to instantiate a class by its name and couldn't find it.

[\#](#content-why-do-i-see-this-error "Permalink")Why do I see this error
-------------------------------------------------------------------------

There are a few usual suspects:

- A typo in the controller name in your route definition.
- A missing or wrong `namespace` at the top of the controller file.
- You're using the **string** controller syntax on Laravel 8+, where the default namespace prefix was removed.
- The autoloader hasn't picked up a newly created class.

[\#](#content-solution "Permalink")Solution
-------------------------------------------

### [\#](#content-use-the-class-based-route-syntax "Permalink")Use the class-based route syntax

Since Laravel 8 the recommended way to reference a controller is by importing it and using its `::class` constant, not a string:

 ```
use App\Http\Controllers\UserController;

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

```

This catches typos at compile time and resolves the namespace for you. The old string form relied on a namespace prefix that no longer exists by default:

 ```
// Fragile, the App\Http\Controllers prefix is no longer applied automatically
Route::get('/users', 'UserController@index');

```

### [\#](#content-check-the-namespace "Permalink")Check the namespace

Open the controller and confirm its namespace matches its folder:

 ```
namespace App\Http\Controllers;

class UserController extends Controller
{
    // ...
}

```

A file in `app/Http/Controllers/Admin/` must declare `namespace App\Http\Controllers\Admin;`.

### [\#](#content-refresh-the-autoloader "Permalink")Refresh the autoloader

If the class genuinely exists and the namespace is right, regenerate Composer's autoload map and clear caches:

 ```
composer dump-autoload
php artisan optimize:clear

```

See [clearing the cache in Laravel](/clear-cache-laravel) for what gets cleared.
