## What it is
Superforms is a SvelteKit form library providing comprehensive server and client-side form validation with support for many validation libraries like Zod, Valibot, Joi, and Yup. It offers a minimal, fully typed API for handling form data, errors, nested data, multiple forms, and client-side validation.

## Use cases
- validate sveltekit forms on server and client
- handle multiple forms on one page in sveltekit
- post nested data structures from a sveltekit form
- prevent losing unsaved form data when navigating away
- add realtime client-side validation to svelte forms
- coerce formdata into typed values including files and arrays
- build single-page app forms in sveltekit

## When to choose
- you are building forms in a SvelteKit project and want typed, validated form data
- you want to use an existing validation library like Zod or Valibot with consistent error handling
- you need nested data, file uploads, or multiple forms with a minimal API

## When to avoid
- you are not using SvelteKit or Svelte
- you need a framework-agnostic form solution for React or Vue
- you only need simple unvalidated HTML forms with no extra features
