Summary

  • Adds InputBaseProps type derived from InputProps by omitting design props (appearance, size)
  • Adds InputBaseState type derived from InputState by omitting the same design props
  • Adds useInputBase_unstable hook that handles:
    • Controlled/uncontrolled value state via useControllableState
    • onChange event handling with the InputOnChangeData callback signature
    • Slot structure: root (span wrapper), input (the actual input element), contentBefore and contentAfter optional slots
    • Native prop partitioning between root and input slots
  • Refactors useInput_unstable to call useInputBase_unstable and spread its results, then add appearance and size
  • Note: contentBefore/contentAfter are user-provided optional slots (not default implementations), so they remain in the base hook
  • Exports new types and hook from packages/react-components/react-input/library/src/index.ts

What base hooks do

Base hooks extract pure component logic — ARIA, keyboard handling, slot structure — WITHOUT styling, design props, or default slot implementations. This allows consumers to build custom-styled variants without taking on the full FluentUI design system.

Test plan

  • Verify TypeScript types compile correctly
  • Verify useInput_unstable still works as before (behavior unchanged, including field control props and overrides)
  • Verify useInputBase_unstable handles controlled/uncontrolled value correctly
  • Verify new exports are available from package index

Adds InputBaseProps, InputBaseState types and useInputBase_unstable hook to the react-input package.
The base hook handles controlled/uncontrolled value state, onChange handling, and slot structure
(root span, input, contentBefore, contentAfter) without design-specific props (appearance, size).
The styled useInput_unstable hook is refactored to call the base hook and spread its results.
