refactor(react-button): streamline button component base hook and remove unused base hooks by dmytrokirpa · Pull Request #35689 · microsoft/fluentui

dmytrokirpa · 2026-01-21T22:15:32Z

Previous Behavior

Fluent-design specific button components (CompoundButton, MenuButton, SplitButton) had separate base hooks that weren't necessary
Base hooks for Button and ToggleButton were in separate files, inconsistent with other component patterns
Custom props (like navType in CarouselButton) were inadvertently forwarded to the DOM after removing getIntrinsicElementProps

New Behavior

Removed unnecessary base hooks:

CompoundButton, MenuButton, and SplitButton no longer have separate base implementations
These components now directly compose useButton_unstable since they don't need design-agnostic variants
Deleted useCompoundButtonBase.ts, useMenuButtonBase.ts, useSplitButtonBase.ts and their associated types

Consolidated base hooks for consistency:

Moved useButtonBase_unstable into useButton.ts
Moved useToggleButtonBase_unstable into useToggleButton.ts`
This aligns with the pattern used in other components where base hooks live alongside their main hooks

Fixed custom props forwarding:

Components now destructure custom props before passing remaining props downstream
Prevents custom props from leaking to the DOM (fixes CarouselButton's navType prop issue)
