User Entity Repository

User Entity

Your application certainly has a user repository. Good news: there is no need to modify it!
The User Entity Repository can be completely decoupled from the user entity used by your application.
This repository should be declared as a Symfony service and shall implement Webauthn\Bundle\Repository\PublicKeyCredentialUserEntityRepository.
Hereafter an example where the application User Repository is injected. This repository uses Doctrine and provides findOneBy* methods.
src/Repository/PublicKeyCredentialUserEntityRepository.php
<?php
declare(strict_types=1);
namespace App\Repository;
use App\Entity\User;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Uid\Ulid;
use Webauthn\Bundle\Repository\PublicKeyCredentialUserEntityRepository as PublicKeyCredentialUserEntityRepositoryInterface;
use Webauthn\PublicKeyCredentialUserEntity;
final class PublicKeyCredentialUserEntityRepository implements PublicKeyCredentialUserEntityRepositoryInterface
{
/**
* The UserRepository $userRepository is the repository
* that already exists in the application
*/
public function __construct(private UserRepository $userRepository)
{
}
/**
* This method creates the next Webauthn User Entity ID
* In this example, we use Ulid
*/
public function generateNextUserEntityId(): string {
return Ulid::generate();
}
/**
* This method saves the user or does nothing if the user already exists.
* It may throw an exception. Just adapt it on your needs
*/
public function saveUserEntity(PublicKeyCredentialUserEntity $userEntity): void
{
/** @var User|null $user */
$user = $this->userRepository->findOneBy([
'id' => $userEntity->getId(),
]);
if (!$user instanceof UserInterface) {
return;
}
$user = new User(
$userEntity->getId(),
$userEntity->getUserIdentifier(),
$userEntity->getDisplayName() // Or any other similar method your entity may have
);
$this->userRepository->save($user); // Custom method to be added in your repository
}
public function findOneByUsername(string $username): ?PublicKeyCredentialUserEntity
{
/** @var User|null $user */
$user = $this->userRepository->findOneBy([
'username' => $username,

return $this->getUserEntity($user);
}

{
/** @var User|null $user */
$user = $this->userRepository->findOneBy([
'id' => $userHandle,
]);
return $this->getUserEntity($user);
}
/**
* Converts a Symfony User (if any) into a Webauthn User Entity
*/
private function getUserEntity(null|User $user): ?PublicKeyCredentialUserEntity
{

return null;
