Form Libraries

Controlled Inputs Versus a Form Library

Keyboard Types validated an order form by hand: a useState per field, a touched flag so the email error waited for blur, and a regular expression. That is a controlled input: React 7,897 state holds the value, and each keystroke re-renders the whole component. Fine for two fields, but a checkout adds an error and touched flag per field, a submitting flag, server errors and focus handling. React Hook Form 351,018 owns that bookkeeping and keeps values in a store outside React state, so a keystroke re-renders only the field that subscribed to it.
