Your first application#

Start with a generated application from the installation guide. You only need a route and a response to get moving.

Return some JSON#

In routes/web.php:

use Elang\Http\Response;

$router->get('/hello/{name}', function (string $name) {
    return Response::json(['message' => 'Hello, '.$name.'!']);
}, 'hello');

Visit /hello/Ada. Elang passes the named route parameter into your handler.

Add a controller#

php elang make:controller HelloController

Register the generated invokable controller:

use App\Controllers\HelloController;

$router->get('/hello', HelloController::class, 'hello.controller');

Constructor dependencies and typed handler dependencies are resolved by the container.

Render HTML#

use Elang\View\View;

$router->get('/welcome', fn (View $view) =>
    $view->render('welcome', ['name' => 'Ada'])
);

Create resources/views/welcome.twig:

<!doctype html>
<html lang="en">
<title>Welcome</title>
<h1>Hello, {{ name }}.</h1>
</html>

Twig escapes name before placing it in HTML.
