Laravel Repository Maker

About Repository Design Pattern:

The Repository Design Pattern is a software design principle commonly used in the development of applications that interact with data storage systems, such as databases. It provides an abstraction layer between the application's data access logic and the underlying data storage, promoting separation of concerns and modularity in the codebase.

In short, the Repository Design Pattern involves creating classes or interfaces called repositories, which encapsulate the methods and operations for interacting with the data storage. These repositories abstract away the details of how data is retrieved, stored, and manipulated, making the application's codebase more maintainable and testable. This pattern also helps in centralizing data access logic, improving code reusability, and facilitating the management of complex queries.

Requirement:

    "require": {
        "php": ">=7.4",
        "laravel/framework": ">=8.0"
    }

Installation

You can install the package via composer:

composer require irfan-chowdhury/repository-maker

Setup

After installation goto config/app.php and paste the bellow line in "providers" array

'providers' => [
    /*
    * Package Service Providers...
    */
    Irfan\RepositoryMaker\RepositoryServiceProvider::class,
]

Usage

If you now run php artisan you will see some new commands in the list:

• make:contract
• make:contract-base
• make:contract-extends
• make:repository
• make:repository-i
• make:repository-base
• make:repository-extends
• make:service
• make:repository-i-s

Commands

$ php artisan make:contract NameContract
$ php artisan make:contract-base
$ php artisan make:contract-extends NameContract
$ php artisan make:repository NameRepository
$ php artisan make:repository-i NameRepository
$ php artisan make:repository-base
$ php artisan make:repository-extends NameRepository
$ php artisan make:service NameService
$ php artisan make:repository-i-s NameRepository

Note:

• Before using repository you have to ensure that your model class exists or not.
• You have to register the dependency in register() method in AppServiceProvider. If you want you can create a custom service provider. Following the bellow code -

use App\Contracts\NameContract;
use App\Repositories\NameRepository;

...

public function register(): void
{
    $this->app->bind(NameContract::class, NameRepository::class);
}

Example

Let you have a User Model according to this namespace App\Models\User.php

Creating Interface

it will generate an interface according to this path app/Contracts/UserContract.php. Here we named this interface as Contract.

$ php artisan make:contract UserContract

Creating a Base Interface

It is optional but if you want to use a base, it will generate an interface according to this path app/Contracts/BaseContract.php. Here we named this interface as Contract.

$ php artisan make:contract-base

Creating an Interface with extends Base Interface

If you want to extends with the Base Interface, it will generate an interface according to this path app/Contracts/UserContract.php and extends with BaseContract.

$ php artisan make:contract-extends UserContract

Note: But before using extends with the Base interface, you have to create a BaseContract before (using only make:contract-base).

Creating Repository

It will generate a repository class according to this path app/Repositories/UserRepository.php.

$ php artisan make:repository UserRepository

Creating Repository with interface

It will generate a repository class with interface according to this path app/Repositories/UserRepository.php and app/Contracts/UserContract.php.

$ php artisan make:repository-i UserRepository

Creating a Base Repository

It is optional but if you want to use a base, it will generate a repository class according to this path app/Repositories/BaseRepository.php.

$ php artisan make:repository-base

Creating a Repository with extends the Base Repository

If you want to extends with Base Repository, it will generate a Repository class according to this path app/Repositories/UserRepository.php and extends with BaseRepository.

$ php artisan make:repository-extends UserRepository

Note: But before using extends with the Base repository, you have to create a BaseRepository class before (using only make:repository-base).

Creating Service Class

It is optional but sometimes we need to use a service class to maintain business logic. If you want to use a service class, it will generate a service class according to this path app/Services/UserService.php.

$ php artisan make:service UserService

Creating Repository with interface and service

It will generate a repository class with interface and service according to this path app/Repositories/UserRepository.php, app/Contracts/UserContract.php, app/Services/UserService.php.

$ php artisan make:repository-i-s UserRepository

After then you have to register in a service provider -

use App\Contracts\UserContract;
use App\Repositories\UserRepository;

...

public function register(): void
{
    $this->app->bind(UserContract::class, UserRepository::class);
}

Inject in Controller/Service class

In your controlleror, you can use them,

use App\Contracts\UserContract;
...

public function __construct(public UserContract $userContract){}

public function index()
{
    return $userContract->latest()->first();
}
