Project status
Symfony now has an official UI kit, and HarmonyUI steps aside in its favour.
Symfony now has an official, stable UI kit: Symfony UX Toolkit and its shadcn kit. HarmonyUI is archived in its favour.
Where HarmonyUI came from
HarmonyUI grew out of my own experience building a professional component library and design system for a company running on Symfony. At the time, Symfony UX Toolkit didn't exist yet, and there was no official way to get accessible, Tailwind-styled Twig components.
HarmonyUI was my take on filling that gap, and sharing what I had learned along the way.
Why it steps aside
Symfony UX Toolkit now exists and is stable. It solves the same problem, as part of the Symfony ecosystem itself. Pointing developers to the official solution is the best way to help them, so that's what this site now does.
Getting started with Symfony UX Toolkit
Head to the Symfony UX Toolkit shadcn kit: its documentation covers installation and every available component.
Thanks to everyone who took a look at HarmonyUI along the way.
