Repositories for Laravel

This is a package that has a simple implementation of a repository pattern for use with Eloquent.

How to use?

Install the package with composer in your project.

composer require hpolthof/repository

Generator command

Now you can create repositories with a new generator command

php artisan make:repository {modelName}

This will create a new repository in a Repositories directory within the app directory.

Model Generator

This package will also extend the make:model generator. When this generator is called with the parameter --all or -a and --repository or -o a repository will also be generated.

The Repository

The repository is an empty class that extends Hpolthof\Laravel\Repository\Repository which implements Hpolthof\Laravel\Repository\Contracts\RepositoryInterface. This interface looks like:

interface RepositoryInterface
{
    public function all(array $columns = ['*']): Collection;
    public function list(string $orderByColumn, string $orderBy = 'desc', array $with = [], array $columns = ['*']): Collection;
    public function builder(Closure $builder, array $columns = ['*']): Collection;

    public function create(array $data): ?Model;
    public function update(array $data, $id): bool;
    public function delete($id): bool;

    public function find($id, array $columns = ['*']): ?Model;
    public function findBy(string $field, $value, array $columns = ['*']): ?Model;
}

Automatic Model Detection

The repository will try to detect the associated Eloquent model that should be used. If the model is named {ModelName}Repository, the model will automatically be used.

Setting the model manually

If the model cannot be detected or if you want to use another name, the $modelName property should be set. This can be done as in the example below:

use App\Demo;

class DemoRepository extends Repository {
    protected $modelName = Demo::class;
}

Usage in controllers

In a controller you can instantiate a repository using dependency injection. See the example below:

class DemoController extends Controller {
    protected $repository;
    
    public function __construct(DemoRepository $repository)
    {
        $this->repository = $repository;
    }
}
