Backend Architecture Repository Pattern

When to use this skill

  • •Abstracting data access
  • •Multiple data sources
  • •Testability
  • •Complex queries

Workflow

  • • Create repository interface
  • • Implement repository
  • • Inject into services
  • • Abstract query logic
  • • Keep repositories focused

Instructions

Interface

php
<?php

namespace App\Repositories;

interface UserRepositoryInterface
{
    public function find(int $id): ?User;
    public function findByEmail(string $email): ?User;
    public function save(User $user): User;
}

Implementation

php
<?php

namespace App\Repositories;

class UserRepository implements UserRepositoryInterface
{
    public function __construct(
        private UserModel $model
    ) {}

    public function find(int $id): ?User
    {
        return $this->model->find($id);
    }

    public function findByEmail(string $email): ?User
    {
        return $this->model->where('email', $email)->first();
    }
}

Resources

  • •Abstract data access
  • •Easy to mock for testing
  • •Switch data sources easily
