TanStack Form
Type-safe headless form library. TanStack (Tanner Linsley). React + Vue + Solid + Svelte support. v1 (Oct 2024). Killer feature: full type-inference from Zod/Valibot schema to field-validation to submit-handler.
Competitor to React Hook Form (most popular, but less type-safe), Formik (legacy). TanStack Form design principle: no-magic, opt-in controlled components. Subscriber pattern for efficient re-renders (only fields that changed). Validation: Zod, Valibot, Yup, ArkType support. Use cases: complex multi-step forms, dynamic fields, async validation. Smaller community than React Hook Form 2024 but growing fast due to superior type-safety. Modern stack: TanStack Form + Zod + shadcn/ui = production-ready form stack.
