Lark

Lark is a modern, lightweight app framework designed specifically for developing REST APIs.

Installation

Create project directory and move to the project directory:

mkdir myapp
cd myapp

Install using composer:

composer create-project lark/app ./

Then, initialize project:

./lark --init

Console

Lark Console is available to assist in creating routes, schemas, models and revisions. Lark Console can be run from the project root directory.

./lark route items

Namespaces can also be used.

./lark route api/items

View all commands with ./lark or ./lark help View command specific help with ./lark help COMMAND

Middleware

Create middleware files in the app/Middleware directory.

Example middleware class:

namespace App\Middleware;
use Lark\Request;
use Lark\Response;

class UserMiddleware
{
	public function auth(Request $req, Response $res): void
	{
		// auth here
	}
}

For this example, the middleware can be setup in app/routes.php like:

router()->matched([App\Middleware\UserMiddleware::class, "auth"]);

Read the framework docs on middleware.

App Class

#todo docs about app class props + methods

MVC Application

Lark can use controllers that are common in MVC applications. Create controller files in the app/Controller directory and extend the base App\Controller class.

Example base controller class app/Controller.php:

namespace App;
use Lark\Response;

abstract class Controller
{
	protected Response $res;

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

Example controller class app/Controller/ItemsController.php:

namespace App\Controller;
use App\Model\Item as ItemModel;

class ItemsController extends \App\Controller
{
    private ItemModel $model;

	public function __construct()
	{
		$this->model = new ItemModel;
	}

	public function get(): void
	{
		$this->res->json(
			$this->model->find()
		);
	}
}

For this example, a route can be setup in app/routes.php like:

router()->get("/items", [App\Controller\ItemsController::class, "get"]);

Read the framework docs on route actions.

Custom Validation Rules

Custom validation rules should be created in the app/Validator directory like app/Validator/MyRule.php.
