Form Libraries Lag as Schema-First Approach Wins in TypeScript

TypeScript developers have adopted schema libraries like Zod, Valibot, and ArkType as the single source of truth for data validation, with 200M weekly downloads for Zod and a joint Standard Schema spec. Major form libraries like Formik and React Hook Form predate this shift, requiring users to maintain separate schema and form definitions. Newer libraries like Formisch are built schema-first, eliminating duplication.
