This bundle is FrankenPHP worker mode friendly.

Symfony bundle that makes Twig fragment sub-requests resilient when using {ignore_errors: true}.

Features

• ✅ HTTP error tolerance — {ignore_errors: true} also covers 403/404 (not only exceptions)
• ✅ Twig fallback — configurable template (or empty string)
• ✅ Optional Sentry — report suppressed failures without breaking the parent page
• ✅ Flex recipe — ships nowo_fragment_kit config
• ✅ FrankenPHP demo — Symfony 8 single-container demo

FrankenPHP: Demos use a single PHP service (FrankenPHP, no nginx). Runtime mode is controlled by FRANKENPHP_MODE in .env (default worker). Set classic for per-request PHP / easier hot-reload (entrypoint swaps in Caddyfile.dev). Recreate the container after changing the mode — no image rebuild. See docs/DEMO-FRANKENPHP.md.

Problem

{{ render(controller(...), {ignore_errors: true}) }} only suppresses exceptions thrown during sub-requests. When the sub-request returns an HTTP error status (403, 404, …), FragmentHandler::deliver() throws a RuntimeException and the parent page still fails with a 500.

Installation

composer require nowo-tech/fragment-kit-bundle

Register the bundle (Flex does this automatically):

Nowo\FragmentKitBundle\NowoFragmentKitBundle::class => ['all' => true],

{{ render(controller('App\\Controller\\WidgetController::index'), {ignore_errors: true}) }}
