The Klaw team has developed reliable, composable, and delightful web forms using TypeScript, react-hook-form, and zod libraries. These tools have enabled the creation of extensible forms that are easy to understand for contributors and provide strong validation capabilities. The use of react-hook-form allows for the creation of composable building blocks for forms, while zod provides a robust schema declaration and validation library. By splitting responsibilities between these two libraries and co-locating form schemas with their respective forms, the Klaw team has achieved its objectives of creating reliable, composable, and delightful web forms.
