README

Interface binder provides an easy way to bind interfaces to implementations within a given array of directories.

Installation

using composer:

composer require netsells/interface-binder

Then publish the config file using the following artisan command:

php artisan vendor:publish --tag=interface-binder

Usage

Add the directories you want to scan for interfaces to the directories array in the interface-binder.php config file:

return [
    /*
    |--------------------------------------------------------------------------
    | Directories to scan for interfaces
    |--------------------------------------------------------------------------
    |
    */

    'directories' => [
        app_path('Features'),
        app_path('Services'),
    ],
];

Then all you need to do is give the interface you whish to bind a BoundTo attribute to tell the Binder which concrete class you wish to bind it to:

namespace App\Features\CodeVerifier;

use App\Models\User;

#[BoundTo(UserCodeVerifier::class)]
interface UserCodeVerifierInterface
{
    public function verifyUserCode(User $user, string $codeGiven): bool;
}

Which is implemented by the following concrete class:

namespace App\Features\CodeVerifier;

use App\Models\User;

class UserCodeVerifier implements UserCodeVerifierInterface
{
    public function verifyUserCode(User $user, string $codeGiven): bool
    {
        return true;
    }
}

And that's it! When you attempt to resolve UserCodeVerifierInterface out of the container you'll get an instance of UserCodeVerifier.
