Bound class not resolving in package

Question

I have an API class that is being bound into the container via a service provider:

public function register()
{
    $this->app->bind('apiclient', fn($app) => new APIClient($app));
}

It is not defined as a package in 'app/config/app.php' as it is in packages.json.

It is constructed with $app as there is a parameter in the URL that is used to switch the base_uri the API uses for its requests - similar to how the Spatie Multi-tenancy application uses a parameter in the URL to switch between landload databases.

This all works throughout the application as anticipated like this:

$user = APIClient::get()
->class('users')
->routing('/123123/123123/123123')
->getResult();

I don't believe the inner workings of the API class to be important, as, essentially, the methods are used to build the full URI and / or any POST data required - if I am wrong, let me know and I will update.

Anyway, the issue at hand. I am looking to use the API to authenticate users with two new user providers that I have added to app/congif/auth.php like this

'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'sl_business',
        ],
]
///
'providers' => [
        'sl_business' => [
            'driver' => 'sl_business'
        ]
]

Where 'sl_business' is registered as an auth provider:

Auth::provider('sl_business', function ($app, array $config) {
    // Return an instance of Illuminate\Contracts\Auth\UserProvider...
    return new EmployeeUserProvider($this->app['hash'], $config['model']);
});

The LoginRequest is correctly using this user provider, however, the EmployeeUserProvider is unable to use the APIClient class. The following, which works fine in the 'application', is not resolving the class in the package:

$user = APIClient::get()
        ->class('employee')
        ->endPoint('login')
        ->route('/'.$loginid.'/'.$password.'/')
        ->getResult();

When I debug with dd(resolve(APIClient::class));, I get:

Target class [Business\API\Auth\Providers\AIPClient] does not exist.

Business\API\Auth\Providers is the namespace of the provider I am working in, and no, the AIPClient does not exist in that directory, it exists in Business\API.

All these files are in the same package, so I guess I am trying to determine the best way to resolve a class from the application within my package, or, if that is even possible.

Answer 1

I changed the class construct method to accept the APIClient as an argument and, change the provider registration to include said client:

Auth::provider('sl_business', function ($app, array $config) {
    // Return an instance of Illuminate\Contracts\Auth\UserProvider...
    return new EmployeeUserProvider($this->app['hash'], $config['model'], new APIClient($this->app));
});   

And the constructor:

public function __construct(HasherContract $hasher, $model, APIClient $api)
{
    $this->model = $model;
    $this->hasher = $hasher;
    $this->api = $api;
}

I can now access the APIClient throughout the user provider as $this->api
