TypeScript

TanStack Form is written 100% in TypeScript with the highest quality generics, constraints, and interfaces to make sure the library and your projects are as type-safe as possible!

Things to keep in mind:

• strict: true is required in your tsconfig.json to get the most out of TanStack Form's types
• Types currently require using TypeScript v5.4 or greater
• Changes to types in this repository are considered non-breaking and are usually released as patch semver changes (otherwise every type enhancement would be a major version!).
• It is highly recommended that you lock your react-form package version to a specific patch release and upgrade with the expectation that types may be fixed or upgraded between any release
• The non-type-related public API of TanStack Form still follows semver very strictly.
