on GitHub

Major Changes

• Release the first alpha of TanStack Form v2.

Minor Changes

• #2419 584fcd9 - Restore field.replaceValue() and add form.replaceFieldValue() for replacing an array element in place

• Feature: Specify default options for createFormHook

• #2426 395d61c - BREAKING: schemaOutputs no longer exists. It is superceded by validatorOutputs. This is only a name change, the schema's result is the same as before

  validatorOutputs now allows a callback validator to specify data that the submit function should know. Schemas do this
  automatically, but now you can do it manually as well:
  run: ({ createOutput }) => createOutput('This is not a validation error and onSubmit can use this')

  The current map is:

  Validator	onSubmit: ({ validatorOutputs }) => ...
  Schema	Schema's output data
  createOutput(X)	X
  Default callback validator	undefined
  Validation error	N/A, onSubmit doesn't run

• #2365 f8bbc25 - Feat: Field groups may now omit identity bindings like fields={{ a: 'a' }}

Patch Changes

• #2436 a679245 - onSubmit now has access to createErrorMap

• Refactor: Adapter formOptions/appFormOptions no longer shim the core types and runtime.

  BREAKING: formOptions.looseSchema and formOptions.strictSchema now require a schema as
  first parameter. This locks down inference to get the best type safety out of it vs. the options object alone.

  Fix: formOptions.looseSchema now allows defaultValues to omit properties instead of
  requiring them to be explicitly undefined.

• Docs: Add JSDoc to code and API sections to website

• Fix: Schema output type now properly guards against dynamically enabled validators

• Fix: Subscription selectors now infer tuple return values without requiring as const.

• Refactor: Use stable validator identity instead of index

• Refactor: Use stable listener identity instead of index

• Refactor: Store Form Groups on trie nodes instead of the form instance
