TwigErrorRenderer

TwigErrorRenderer is a Slim ErrorRenderer that renders errors using Twig templates.

You can specify a separate Twig template for each Exception along with a default catch-all template. It is recommended to only enable TwigErrorRenderer in production.

Configuration

Reun PHP App Template

TwigErrorRenderer is automatically configured for Reun PHP App Template in the included definitions. Just include the definitions to enable it in production.

// AppDefinitions.php
$c += TwigUtilitiesDefinitions::getDefinitions();

Manual configuration

// Default error template
$defaultTemplate = "public/errorPages/default.twig";
$templates = [
    // Render Twig loader errors as 404
    LoaderError::class => "public/errorPages/404.twig",
    // Render Slim's NotFoundException as 404
    HttpNotFoundException::class => "public/errorPages/404.twig",
];

$twigErrorRenderer = new TwigErrorRenderer($twig, $defaultTemplate, $templates);

$app
  ->addErrorMiddleware($isDev, true, true)
  ->getDefaultErrorHandler()
  ->registerErrorRenderer("text/html", $twigErrorRenderer);

See the included definitions and Slim documentation for additional information.
