README

A laravel package to generate files for layered architecture and automate interface bindings.

Recommended Laravel version: ^9.0

Go to Laravel Docs to see support policy.

Summary

• Requirements
• Installation
• Configuration
• Usage
  • Generate Layers
  • Generate Layers with Subfolders
  • Generate Services with more than one repository

Requirements

"php": "^8.0.2"
"symfony/finder": "^6.3"
"illuminate/support": "^9.0 || ^10.20"
"illuminate/console": "^9.0 || ^10.20"

Installation

composer require williamjss/layers --dev

Configuration

php artisan vendor:publish --tag=layers

This command will copy Layers config to your project config folder

<?php

return [

    'namespace' => [
        'repositories' => 'Repositories',
        'services' => 'Services',
    ],

    'path' => [
        'models' => app_path('Models'),
        'repositories' => app_path('Repositories'),
        'services' => app_path('Services'),
    ]
];

Into this file, you can switch the services/repositories default path. For this, keep the namespace and path keys both equals.

Usage

Using the layers artisan command, we can be generate files for repositories (interface and eloquent) and services.

php artisan layers + {option} + {model name}

Available options:

• -e or --eloquent : Generate a repository eloquent for the model
• -i or --interface : Generate a repository interface for the model
• -s or --service : Generate a service for the model
• -r or --repository : Generate a repository interface and eloquent for the model
• -a or --all : Generate a service, repository interface and repository eloquent for the model
• --wr : Specify the service's repositories

Subcommands

• php artisan layers:repository --eloquent : the same as php artisan layers --eloquent
• php artisan layers:repository --interface : the same as php artisan layers --interface
• php artisan layers:service : the same as php artisan layers --service
• php artisan layers:binds : List all binds from application

Generate Layers

php artisan layers --all User

This command will generate 3 files:

• app/Repositories/UserRepositoryInterface.php
• app/Repositories/UserRepositoryEloquent.php
• app/Services/UserService.php

UserRepositoryInterface.php

<?php

namespace App\Repositories\User;

use App\Models\User;

interface UserRepositoryInterface
{
    public function __construct(User $user);

    /**
     * Stores a new instance of User in the database
     * @param \Illuminate\Support\Collection|array|int|string $data
     * @return User
     */
    public function store($data);

    /**
     * Returns all instances of User from the database
     * @param array|string $columns
     * @param array<array> $filters
     * @return \Illuminate\Database\Eloquent\Collection<int, static>
     */
    public function getList($columns=['*'], $filters=null);

    /**
     * Returns an instance of User from the given id
     * @param int|string $id
     * @return User
     */
    public function get($id);

    /**
     * Updates the data of an instance of User
     * @param \Illuminate\Support\Collection|array|int|string $data
     * @param int|string $id
     * @return User
     */
    public function update($data, $id);

    /**
     * Removes an instance of User from the database
     * @param int|string $id
     * @return int
     */
    public function destroy($id);
}

UserRepositoryEloquent.php

<?php

namespace App\Repositories;

use App\Models\User;

class UserRepositoryEloquent implements UserRepositoryInterface
{
    protected $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    /**
     * Stores a new instance of User in the database
     * @param \Illuminate\Support\Collection|array|int|string $data
     * @return User
     */
    public function store($data)
    {
        return $this->user->create($data);
    }

    /**
     * Returns all instances of User from the database
     * @param array|string $columns
     * @param array<array> $filters
     * @return \Illuminate\Database\Eloquent\Collection<int, static>
     */
    public function getList($columns=['*'], $filters=null)
    {
        return $this->user->where($filters)->get($columns);
    }

    /**
     * Returns an instance of User from the given id
     * @param int|string $id
     * @return User
     */
    public function get($id)
    {
        return $this->user->find($id);
    }

    /**
     * Updates the data of an instance of User
     * @param \Illuminate\Support\Collection|array|int|string $data
     * @param int|string $id
     * @return User
     */
    public function update($data, $id)
    {
        $user = $this->user->find($id);
        $user->update($data);
        return $user;
    }

    /**
     * Removes an instance of User from the database
     * @param int|string $id
     * @return int
     */
    public function destroy($id)
    {
        return $this->user->find($id)->delete();
    }
}

UserService.php

<?php

namespace App\Services;

use App\Repositories\UserRepositoryInterface;

class UserService
{
    private $repoUser;

    public function __construct(
        UserRepositoryInterface $repoUser,
    )
    {
        $this->repoUser = $repoUser;
    }

    // Add your functions here...
}

Generate Layers with Subfolders

php artisan layers --repository User.Address

This command will generate 2 files:

• app/Repositories/User/AddressRepositoryInterface.php
• app/Repositories/User/AddressRepositoryEloquent.php

Generate Services with more than one repository

php artisan layers --service --wr=Address --wr=User Person

This command will generate the follow file:

<?php

namespace App\Services;

use App\Repositories\UserRepositoryInterface;
use App\Repositories\User\AddressRepositoryInterface;

class PersonService
{
    private $repoAddress;
    private $repoUser;

    public function __construct(
        AddressRepositoryInterface $repoAddress,
        UserRepositoryInterface $repoUser,
    )
    {
        $this->repoAddress = $repoAddress;
        $this->repoUser = $repoUser;
    }

    // Add your functions here...
}
