Installation

composer require kenokokoro/laravel-basetree

After the package is pulled in, register the Service Provider in your AppServiceProvider:

    public function register() 
    {
        $this->app->register(BaseTree\Providers\BaseTreeServiceProvider::class);
    }

That should be it.

Description

Basic multilayer structure which is basically meant for RESTful APIs and Web CRUD resources. Includes base classes which by their extending should allow working RESTful API endpoint and CRUD operations for single resource. It forces the code to be separated in business logic layer and data access layer, which results in much cleaner code.

Includes

Error handling just by extension of the BaseTree\Exception\LaravelHandler.php or BaseTree\Exception\LumenHandler
Base controllers with required methods

a.BaseTree\Controller\Laravel\JsonController.php for RESTful APIs on Laravel framework

b.BaseTree\Controller\Lumen\JsonController.php for RESTful APIs on Lumen framework

c.BaseTree\Controller\WebController.php for web based CRUD operations on Laravel only
Base resource which is basically a class dedicated for the business logic on given Model BaseTree\Resources\BaseResource.php
Generic separated classes for http or json response.
Basic model interface which is used in every resource and data access layer BaseTree\Models\BaseTreeModel.php. Created models should implement this model.
Data access layer which wraps the models in separate repository for better structure and re-usability of the already used database calls. Every repository have own interface and implementation.
Each database update is wrapped inside transaction, so if you don't receive your controllers response, and got an exception nothing will be persisted in the database.
LaravelTestCase and LumenTestCase which contains a lot of helpers for integration testing using the PHPUnit framework.

Usage

Requirements

Created migration and Model for your resource. Note that the model should extend the BaseTree model.

So in your app\Models directory create Foo.php

    namespace App\Models;
    
    use Illuminate\Database\Eloquent\Model;
    use BaseTree\Models\BaseTreeModel;
    
    class Foo extends Model implements BaseTreeModel 
    {
        protected $fillable = ['name', 'description'];
    }

You must set the $fillable attribute in order to works properly.

Create the data access layer for the created model. (Automatic creation)

For example you can create a folder under your app folder called DAL and just a folder with the model name, in this case Foo

So in app/DAL/Foo create FooRepository.php:

    namespace App\DAL\Foo;

    use BaseTree\Eloquent\RepositoryInterface;

    interface FooRepository extends RepositoryInterface 
    {
    }

Now the repository implementation that is implementing the newly created interface.

In app/DAL/Foo create EloquentFoo.php

    namespace App\DAL\Foo;

    use BaseTree\Eloquent\BaseEloquent;
    use App\Models\Foo;

    class EloquentFoo extends BaseEloquent implements FooRepository 
    {
        public function __construct(Foo $model)
        {
            parent::__construct($model);
        }
    }

Now bind everything in your custom created service provider. I would do:

In app/DAL create DalServiceProvider.php

    namespace App\DAL;

    use Illuminate\Support\ServiceProvider;
    use App\DAL\Foo\FooRepository;
    use App\DAL\Foo\EloquentFoo;
    
    class DalServiceProvider extends ServiceProvider 
    {
        public function register() {
            $bindings = [
                FooRepository::class => EloquentFoo::class,
                # Every other repository should be registered here
            ];
            
            foreach($bindings as $interface => $implementation) {
                $this->app->bind($interface, $implementation);
            }
        }
    }

And register the DalServiceProvider in your AppServiceProvider:

    use App\DAL\DalServiceProvider;

    ...
    public function register() {
        $this->app->register(DalServiceProvider::class);
    }

With this you are done with the Data Access Layer structure. You can inject you interfaces whenever you need and reuse your queries.

Create the dedicated resource responsible for the business logic rules and interaction with the data access layer. Create a folder inside your app folder called Resources or BLL, and in there you can keep you model resources. (Automatic creation)

In app/BLL create the file FooResource.php:
```
    namespace App\BLL;
    
    use BaseTree\BLL\BaseResource
    use App\DAL\FooRepository;
    
    class FooResource extends BaseResource
    {
        public function __construct(FooRepository $repository) 
        {
            parent::__construct($repository);
        }
    }
```
With this you are pretty much done for the resource, but this package includes some helper interfaces to help you structure your validations, creating and updating.

The BaseTree\Resources\Contracts\ResourceValidation interface will force you to put the storeRules(), updateRules() and destroyRules(). Having this interface implemented on your resource, your requests on store(), update() and destroy() would be validated. If you don't need any validation for certain method, just return empty array. You can also use them as separate depending on your needs (Check the BaseTree\Resources\Contracts\ResourceValidation, all the extended interfaces have their own method and can be used individually if needed)

The BaseTree\Resources\Contracts\ResourceCallbacks interface contains the created() and updated() methods which are basically hooks after resource is created or updated. Passed $dependencyAttributes values contains everything except the $fillable attributes that are set on your model. This is good since using this values you can easily update your relations. The callbacks also can be used individually if needed just like the resource validations that are mentioned above (BaseTree\Resources\Contracts\ResourceCallbacks check the extending interfaces)

The $attributes contains the $fillable attributes.

Now the controller. Each controller should extend the BaseTree\Controllers\Laravel\JsonController for laravel and BaseTree\Controllers\Lumen\JsonController for lumen when using json and BaseTree\Controllers\Laravel\WebController depending on your need. (Automatic creation)

In app/Http/Controllers (or inside somewhere else) create your FoosController.php.

    namespace App\Http\Controllers;
    
    use BaseTree\Controllers\Laravel\JsonController;
    use App\BLL\FooResource;
    
    class FoosController extends JsonController 
    {
        public function __construct(FooResource $resource) 
        {
            parent::__construct($resource);
        }
    }

Now you are ready for your route:

    Route::resource('foos', 'FoosController')->except(['edit']);

Using the exception handler from the base-tree. In your App\Exceptions\Handler do the following:

    namespace App\Exceptions;

    use BaseTree\Exception\LaravelHandler as BaseTreeHandler;

    class Handler extends BaseTreeHandler
    {
    }

Request - Response

Note that you will always have to set your Accept header to application/json.

Having this being said, now you have RESTful API with just few classes creation:

Visiting /api/foos&datatable=1 will return you response which can be used as ajax source for jquery datatables plugin.
Visiting /api/foos&paginate=1&perPage=10 will return you paginated response with next and previous urls in the response. Default value for perPage is 15.
Visiting api/foos&constraints[0]=name|=|bar will return all foos with name bar. You can build query strings using the php function http_build_query(['constraints' => ['name|=|bar', 'active|1']]).
Visiting api/foos&fields[0]=Bar will return all foos but with the Bar relation included in the response.

The structure for the constraints value is columnName|operator|value. If you need to add constraint by another column: columnName|operator|`otherColumn`

Testing

This package contains database test class which can make your database required testing much easier.

Setup your DB_CONNECTION to testing inside phpunit.xml:

    <env name="DB_CONNECTION" value="testing"></env>

Setup your testing connection inside your database.php config file: In config/database.php under connections add:
```
    'testing' => [
        'driver' => 'sqlite',
        'database' => ':memory:',
    ],
```
This will give the ability for the BaseTree\Tests\Traits\DatabaseMigrations which is included inside BaseTree\Tests\LaravelDatabaseTestCase or BaseTree\Tests\LumenDatabaseTestCase to migrate and seed before your test start, and rollback after your test is finished. Like this you will always have fresh database.

Testing models

In tests/Models create FooTest.php which corresponds to your Foo.php Model. Let's assume that your Foo model has one Bar model.

    namespace Tests\Models;

    use App\Models\Foo;
    use App\Models\Bar;
    use BaseTree\Tests\LaravelDatabaseTestCase;

    class FooTest extends LaravelDatabaseTestCase
    {
        /** @test */
        public function a_foo_has_one_bar()
        {
            $foo = create(Foo::class);
            $bar = create(Bar::class);

            $foo->bar()->save($bar);

            $this->assertHasOne($foo, $bar, 'bar', ['id' => $bar->id, 'foo_id' => $foo->id]);
        }
    }

Testing controller endpoints

After you create your FoosController which extends the DatabaseTestCase you can:

    use BaseTree\Responses\JsonResponse;
    use App\Models\Foo;

    ...
    
    /** @test */
    public function it_should_fetch_all_foos(): void
    {
        $response = $this->jsonGet(route("foos.index"));
        $response->assertStatus(JsonResponse::HTTP_OK)->assertJsonStructure(['status', 'message', 'data']);
    }
    
    /** @test */
    public function it_requires_data_in_order_to_store_foo(): void
    {
        $response = $this->jsonPost(route('foos.store'));
        $response->assertStatus(JsonResponse::HTTP_UNPROCESSABLE_ENTITY)->assertJsonStructure([
            'status',
            'message',
            'validator'
        ]);
        $validator = $response->json()['validator'];

        $this->assertCount(7, $validator);
        
        # Response messages assertions. Third argument is value that laravel will translate without the _
        $this->assertFieldRequired($validator, 'name');
        $this->assertEmailField($validator, 'user_email', 'user email');
        $this->assertPasswordIsConfirmed($validator, 'password');
        $this->assertValueIn($validator, 'value_from_enum', 'value from enum');
        $this->assertFieldExist($validator, 'id');
        $this->assertFieldIsArray($validator, 'array');
        $this->assertValueIsUnique($validator, 'unique_column', 'unique column');
    }
    
    /** @test */
    public function foo_can_be_stored(): void
    {
        $response = $this->jsonPost(route('foos.store', ['name' => 'Foo Name']));
        $response->assertStatus(JsonResponse::HTTP_UNPROCESSABLE_ENTITY)->assertJsonStructure([
            'status',
            'message',
            'validator'
        ]);
        
        $this->assertCreated(new Foo, ['name' => 'Foo Name']);
    }

Feeling limited with just empty files

If you need additional functionality you can always override the parent methods. For example, if you want to generate slug for you resource which only has name as value, in your app\BLL\FooResource.php

    namespace App\BLL;
    
    use BaseTree\Resources\BaseResource;
    use App\DAL\FooRepository;
    
    class FooResource extends BaseResource
    {
        public function __construct(FooRepository $repository) 
        {
            parent::__construct($repository);
        }
        
        public function store(array $attributes) 
        {
            $attributes['slug'] = str_slug($attributes['name']);
            # Or whatever logic you need here
            
            return parent::store($attributes);
        }
        
    }

Same thing works for controllers and DAL. Whatever you need to be customized can be extended and overwritten.

Artisan generators

Generate data access layer. This command will generate repository and eloquent implementation. Don't forget to bind this into your ServiceProvider

Usage:
  php artisan basetree:dal [options]

Options:
      --model[=MODEL]                              Fully qualified model name including the namespace
      --interface-folder[=INTERFACE-FOLDER]        Folder where to create the DAL interface [default: "app/DAL/[model-name]"]
      --interface-namespace[=INTERFACE-NAMESPACE]  Namespace to create the DAL interface under [default: "App\DAL\[model-name]"]
      --dal-folder[=DAL-FOLDER]                    Folder where to create the DAL implementation [default: "app/DAL/[model-name]"]
      --dal-namespace[=DAL-NAMESPACE]              Namespace to create the DAL implementation under [default: "App\DAL\[model-name]"]

Example: php artisan basetree:dal --model=App\\Models\\User

Generate business logic layer. This will generate a resource with the repository interface injected inside your contructor

Usage:
  php artisan basetree:bll [options]

Options:
      --model[=MODEL]                  Fully qualified model name including namespace
      --dal-interface[=DAL-INTERFACE]  Fully qualified data access layer name including namespace
      --folder[=FOLDER]                Folder where to create the BLL [default: "app/BLL/"]
      --namespace[=NAMESPACE]          Namespace to create the BLL under [default: "App\BLL"]

Example: php artisan basetree:bll --model=App\\Models\\User --dal-interface=App\\DAL\\User\\UserRepository

Generate controller. The generated controller will have the given business logic layer injected inside the constructor

NOTE: At this point, the generator is only creating controller extending the RestfulJsonController. You will have to change the extension manually on the generated controller in order to extend the WebController or create it manually

Usage:
  php artisan basetree:controller [options]

Options:
      --model-plural[=MODEL-PLURAL]  Plural form of the model name. For instance if the model is User, you should send here Users
      --bll[=BLL]                    Fully qualified business logic layer name including namespace
      --folder[=FOLDER]              Folder where to create the controller [default: "app/Http/Controllers/Api/"]
      --namespace[=NAMESPACE]        Namespace to create the controller under [default: "App\Http\Controllers\Api"]

Example: php artisan basetree:controller --model-plural=users -bll=App\\BLL\UserResource

Publish the docker-compose architecture. Check out the .env.docker-compose.example for the required variables to make the docker containers just work.
```
Usage:
  php artisan basetree:boilerplates [options]

Options:
      --docker-compose  Publish the docker structure

Help:
  Publish some already predefined environments.
      --docker-compose: Docker environment for local development (nginx 1.13, php7.1-fpm + composer, npm 3.3, nodejs 6.7, MariaDB 10.3, phpmyadmin 4.7)
```
Example: php artisan basetree:boilerplates --docker-compose

Required variables:
- DOCKER_HOST_UID=1000 # Your host user id. Check it by doing echo $UID or id username.
- DOCKER_HOST_GID=1000 # Your host group id. Check it by doing echo $GID or id username.
- DATABASE_LOCAL_STORAGE=/opt/mariadb/project # Where to keep your database files on your host machine. This is required since if you run docker-compose down -v this will destroy the data in your database, if the storage is not mounted on your host machine.
- PMA_PORT=81 # Public exposed port for PhpMyAdmin. If running on QA environment or if you don't need you can remove if from the docker-compose.yml file, or by running docker-compose stop phpmyadmin
- NGINX_SERVER_NAME=localhost # The virtual host name
- NGINX_PORT=80 # Public exposed port for the nginx container. Should be 80 in order to avoid adding your port after your domain. Example: If your NGINX_PORT=8080, you will have to access it: localhost:8080 on your browser. Also if you already have some services listening to the given port, you will have to shut them down.
- CONTAINER_ROOT=/application # The name of your project inside the container.
- DB_ROOT_PASSWORD=root-pass123 # MariaDB root password
- QA_HTTP_HOST= # If you are running multiple docker instances, and you want to bind them all to 80 port, you will have to specify the fastcgi_param HTTP_HOST here, in order your application to redirect to your proxy url.
- DB_HOST=mariadb # If you are using the docker mariadb instance, instead of your own already installed.
After all this is set up, you will have to run docker-compose -f docker-compose.yml -f qa.docker-compose.yml -f dev.docker-compose.yml up -d and wait for the build to finish. Check your containers status by running docker-compose ps. You will have to see something like this:
```
        Name               Command                          State               Ports                
---------------------------------------------------------------------------------------------------------------------------------------------------------------------
tutorial_app_1         docker-php-entrypoint /sta ...       Up           443/tcp, 0.0.0.0:80->80/tcp, 9000/tcp
tutorial_mariadb_1     docker-entrypoint.sh mysqld          Up           0.0.0.0:3307->3306/tcp               
tutorial_phpmyadmin_1  /run.sh phpmyadmin                   Up           0.0.0.0:81->80/tcp 
```

Lumen support

The same explanation about laravel applies for Lumen as well, and the behaviour should be equal for lumen and laravel. The special cases for lumen are:

The lumen controller is not the same with the laravel controller

    namespace App\Http\Controllers;
    
    use BaseTree\Controllers\Lumen\JsonController;
    use App\BLL\FooResource;
    
    class FoosController extends JsonController 
    {
        public function __construct(FooResource $resource) 
        {
            parent::__construct($resource);
        }
    }

Using the exception handler from the base-tree. In your App\Exceptions\Handler do the following:

    namespace App\Exceptions;

    use BaseTree\Exception\LumenHandler as BaseTreeHandler;

    class Handler extends BaseTreeHandler
    {
    }

Database required testing In tests/Models create FooTest.php which corresponds to your Foo.php Model. Let's assume that your Foo model has one Bar model.

    namespace Tests\Models;

    use App\Models\Foo;
    use App\Models\Bar;
    use BaseTree\Tests\LumenDatabaseTestCase;

    class FooTest extends LumenDatabaseTestCase
    {
        /** @test */
        public function a_foo_has_one_bar()
        {
            $foo = create(Foo::class);
            $bar = create(Bar::class);

            $foo->bar()->save($bar);

            $this->assertHasOne($foo, $bar, 'bar', ['id' => $bar->id, 'foo_id' => $foo->id]);
        }
    }
