What it is

TanStack Form is a headless, framework-agnostic form state management library that handles complex form validation, field state, and workflows across TypeScript/JavaScript, React, Vue, Angular, Solid, and Lit. It provides reactive hooks and sync/async validation with full TypeScript support, requiring developers to bring their own UI components. Monorepo with framework-specific packages: packages/form-core contains the shared FormApi, FieldApi, validation logic, and types; packages/react-form, packages/angular-form, packages/vue-form, etc. wrap core into framework-specific hooks/services; packages/form-devtools and packages/react-form-devtools provide debugging UIs;…

Start here

Open these first:

• packages/form-core/src/FormApi.ts — Core form state management engine; all framework adapters depend on this central API.
• packages/form-core/src/FieldApi.ts — Field-level state and validation logic that underpins every form input across all frameworks.
• packages/form-core/src/types.ts — TypeScript type definitions for form, field, and validation that establish the contract across all adapters.
• packages/react-form/src/useForm.tsx — Primary React hook for integrating form-core into React; template for other framework adapters.
• packages/form-core/src/ValidationLogic.ts — Validation pipeline and error handling; critical for consistent validation across frameworks.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/TanStack/form.git
cd form
pnpm install
pnpm run dev

Uses pnpm@11.21.0+ (specified in packageManager field); verify pnpm is installed before cloning.

Daily commands:

pnpm run dev

Starts watch mode with all packages via nx watch --all -- pnpm run build:all. For testing: pnpm run test:lib (unit tests), pnpm run test:build (build verification), pnpm run test:types (TypeScript checks).

Key cautions & unknowns

• pnpm version is strictly pinned to 11.21.0 with SHA512 hash—using different pnpm versions may cause lockfile mismatches. Nx is the build orchestrator; running tasks without Nx (e.g., npm run build) will fail.…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
