SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Tanstack-form solves the problem of building and validating complex client-side forms reliably, with correct state management and dependable TypeScript typing.

Core Features & Use Cases

Headless, deep TypeScript form state: Manage form and field state using useForm, form.Field, and form.Subscribe without locking into a specific UI library.
Validation that scales: Support synchronous and asynchronous validation (with debouncing), plus schema validation adapters (Zod, Valibot, Yup).
Advanced form modeling: Handle dependent fields (cross-field revalidation via listeners), array fields (mode="array"), and server-side validation integration (e.g., Next.js server actions).
Use Case: Create a sign-up form where email validates on blur, username checks asynchronously, password and confirmPassword stay consistent as the user types, and a dynamic list of contacts can be added/removed.

Quick Start

Ask the AI to show you how to implement a typed sign-up form with TanStack Form using Zod validation and async username availability checking.

FAQPage Schema

How do I build type-safe forms with synchronous and asynchronous validation in React?▼

Build type-safe forms with synchronous and asynchronous validation using a headless form state manager that provides fine-grained reactivity. It supports debounced async checks, deep TypeScript field path safety, and schema adapters like Zod without locking you into a specific UI library.

What's the best way to handle cross-field revalidation for dependent inputs like password and confirm password?▼

Handle cross-field revalidation for dependent inputs by attaching listeners that trigger validation on related fields when one changes. This ensures fields like password and confirm password stay consistent as the user types, maintaining correct meta state via onChange and onBlur handlers.

Can I validate form fields asynchronously using Zod schemas?▼

Yes, you can validate form fields asynchronously using Zod schema adapters. The system supports validators that return undefined for valid inputs, integrates zod-form-adapter for schema-based rules, and allows debounced asynchronous checks like username availability directly within the form state.

How do I add and remove dynamic array fields in a TypeScript form?▼

Add and remove dynamic array fields by configuring array fields with mode="array". This approach manages dynamic lists of items, such as a list of contacts, while preserving deep TypeScript field path safety and maintaining correct validation state across the added or removed items.

Does headless form state management work with server-side validation in frameworks like Next.js?▼

Headless form state management works with server-side validation by integrating with server actions in frameworks like Next.js. It wires onBlur and onChange handlers to maintain correct meta state on the client, seamlessly bridging frontend reactivity with backend validation responses.
