React Hook Form

React Hook Form is a library for building and validating forms in React. It keeps re-renders low, which helps forms stay fast as they grow.

You register inputs with a hook, and the library tracks their values, errors and submission state. Validation rules can be written inline, such as required or pattern, or through a schema resolver such as Zod or Yup. It also works with standard HTML validation attributes and with most UI kits.

• Inline validation rules such as required and minLength
• Schema support through resolvers for Zod and Yup
• Tracks dirty, touched and submitted form state
• TypeScript support with typed field names
• No dependencies, so the package stays small

React developers who build forms of any size, from a sign-up page to multi-step data entry, and who want fewer re-renders and less state code.

React Hook Form is open source and released under the MIT license, so it is free to use. The library manages form state locally, so you may still need a separate tool for state shared across the whole app. Check the documentation for the resolver you choose.
