react-resize — my own: a React component that reports its own size to its children.
A form builder SaaS. Drag fields into place, publish to a public link, and responses land in tables and charts in real time.
The interesting part is the permission model: an anonymous stranger must be able to insert a response into a published form, but must never read anyone's responses. That rule lives in Postgres under Row Level Security with a SECURITY DEFINER helper — not in the application server, where a forgotten check opens the hole. Realtime is a domain port rather than a useEffect, so swapping Supabase for another provider touches one adapter.
