Documentation

Register an exception converter

Exception converters transform exceptions to HTTP responses. They are separate from the main converter registry to keep concerns separated.

Examples:

// Handle 404 errors
$dispatcher->registerExceptionConverter(function(NotFoundException $e): ResponseInterface {
    return new Response(404, ['Content-Type' => 'text/html'], render('404'));
});

// Handle validation errors
$dispatcher->registerExceptionConverter(function(ValidationException $e): ResponseInterface {
    $json = json_encode(['errors' => $e->errors]);
    return new Response(400, ['Content-Type' => 'application/json'], $json);
});

// Generic error handler
$dispatcher->registerExceptionConverter(function(\Throwable $e): ResponseInterface {
    $statusCode = 500;
    $message = Mini::$mini->debug ? $e->getMessage() : 'Internal Server Error';
    return new Response($statusCode, ['Content-Type' => 'text/html'], render('error', compact('message')));
});
