summary
Author of Redux-Form builds a new engine called Final Form that is framework‑agnostic and claims 4.6 k gzipped core plus React Final Form bindings ~3k for a 7.5k total, uses an observer/subscription API to subscribe to slices of form state so only needed pieces rerender, demonstrates handling huge forms (50–200 fields) with per‑field subscriptions, ships plugins like final-form-focus that scrolls/focuses the first error, and shows live coding where the library works as advertised.
