Superforms

Developed for SvelteKit applications, it is a form management library that offers server and client-side verification support. Zod can work integrated with a large number of verification libraries, such as Valibot and JSON Schema; it supports nested data structures and file uploads. Thanks to its progressive enhancement feature, JavaScript retains form functionality even when disabled.

  • With Tainted form detection and snapshot features, you prevent users from losing their unsaved data.
  • You send complex and interlocking data structures like a RPC call without being plugged into FormData limitations.
