Summary

Fixes: #2496

The canvas-kit-react/common README held reference documentation that was not reachable from Storybook, where the rest of the documentation lives. This moves it, following the split proposed on the issue.

Two new pages under Hooks and Utilities:

  • Unique IDs: useUniqueId, generateUniqueId, setUniqueSeed and resetUniqueIdCount. These were only described in passing, useUniqueId on the Accessibility overview and the two test helpers on the Testing guide, with no reference page of their own.
  • Bidirectionality: isElementRTL and the logical-properties guidance. This had no Storybook page at all. It uses the existing examples/RTL.tsx, which nothing referenced.

ExtractProps is added to the existing Compound Component Utilities page, beside createComponent, which was already documented there.

The README keeps Installation, CanvasProvider and Focus rings, and points at Storybook for everything that moved. Theming already has its own guide, so it is linked rather than repeated.

One correction made on the way. The README's heading was ## useElementRTL, but the exported function is isElementRTL: the body text and the code example both used the correct name, and the Bidirectionality section linked to an #iselementrtl anchor that the wrong heading never produced. useIsRTL was deprecated in #3477. The new page uses the correct name throughout.

Checklist

I don't have permission to add labels on this repo. Happy for a maintainer to add ready for review.

Where Should the Reviewer Start?

modules/react/common/README.md, to see what moved and what stayed, then the two new files in modules/react/common/stories/mdx/.

Areas for Feedback? (optional)

  • Documentation

Two things worth a second opinion:

  1. Page split. Unique IDs and Bidirectionality are separate pages rather than one "Common utilities" page, on the grounds that they are looked up for different reasons. Happy to merge them if you'd rather have one.
  2. How much the README should keep. I left Installation, CanvasProvider and Focus rings in place and replaced the rest with links. If you'd prefer the README reduced further, or kept whole with Storybook duplicating it, say which and I'll change it.

Testing Manually

Run Storybook and check Hooks and Utilities / Unique IDs and Hooks and Utilities / Bidirectionality render, that the RTL example is interactive on the Bidirectionality page, and that the new ExtractProps section appears on Hooks and Utilities / Compound Components between createComponent and createModelHook.

Summary by CodeRabbit

  • Documentation
    • Added Storybook guides for bidirectionality, component prop utilities, and unique ID utilities, with examples and usage guidance.
    • Updated the common README’s links and RTL guidance, including direction-aware keyboard handling with isElementRTL.
    • Documented CSS logical properties, direction-specific styling, and the deprecation of useIsRTL and uniqueId, with guidance on alternatives.

The common package README held reference documentation that was not
reachable from Storybook, where the rest of the documentation lives.

Adds two pages under Hooks and Utilities:

- Unique IDs: useUniqueId, generateUniqueId, setUniqueSeed and
  resetUniqueIdCount, which were only described in passing on the
  Accessibility and Testing guides.
- Bidirectionality: isElementRTL and the logical-properties guidance,
  which had no Storybook page at all. Uses the existing RTL example,
  which nothing referenced.

Adds ExtractProps to the existing Compound Component Utilities page,
beside createComponent, which was already documented there.

The README keeps Installation, CanvasProvider and Focus rings, and
points at Storybook for everything that moved. Theming already had its
own guide and is not duplicated.

Fixes the heading for isElementRTL, which the README called
useElementRTL. The body and the example both used isElementRTL, and the
Bidirectionality section linked to an #iselementrtl anchor the wrong
heading never produced. useIsRTL was deprecated in Workday#3477.

Walkthrough

The common README now links to Storybook guidance for bidirectionality, component utilities, and unique IDs. New Storybook pages document those topics, and the README adds a link to the theming guide.

Changes: Common documentation

Layer / File(s) Summary
Bidirectionality guidance
modules/react/common/stories/mdx/Bidirectionality.mdx
Documents RTL setup, CSS logical properties, :dir() styling, and direction-aware keyboard handling with isElementRTL. It also notes that useIsRTL is deprecated.
Compound component utilities
modules/react/common/stories/mdx/CompoundComponentUtilities.mdx
Documents ExtractProps for default element attributes, an explicitly selected element, and component-declared props only.
Unique ID utilities
modules/react/common/stories/mdx/UniqueIds.mdx
Documents unique ID APIs, examples, server-rendering and testing guidance, and the deprecation of uniqueId.
README documentation links
modules/react/common/README.md
Updates the table of contents and reformats examples. Replaces detailed RTL, component utility, and unique ID guidance with Storybook links, and adds a link to the theming guide.

Comment thread modules/react/common/README.md Resolved
Rewrites the table of contents. It pointed at eight anchors this PR
removed, and it was already stale before that: it listed Input Provider
sections that do not exist and omitted Focus rings and RTL. It now
matches the headings in the file.

Corrects the ArrowRight example to goToPrevious and goToNext. The old
README used goToPreviousRow and goToNextRow, but collection/lib/keyUtils
binds those to ArrowUp and ArrowDown, and ArrowLeft and ArrowRight to
goToPrevious and goToNext. The example was moved verbatim, so the error
came with it.

Qualifies the server-side rendering note on setUniqueSeed. A shared seed
alone does not align IDs: they are the seed plus an incrementing
counter, so both sides must also start from the same count and generate
in the same order.

Thanks, all three were worth making. Pushed in 0016d8d3.

Table of contents. Fixed, and it was worse than the finding says. The TOC pointed at eight anchors this PR removed, but it was already stale on master: it listed Input Provider, Definitions, Static Properties and InputTypes sections that do not exist in the file, and omitted Focus rings and RTL, which do. It now matches the headings exactly.

ArrowRight. Correct, and modules/react/collection/lib/keyUtils.ts settles it: ArrowLeft and ArrowRight map to goToPrevious and goToNext, while goToPreviousRow and goToNextRow are bound to ArrowUp and ArrowDown. The example now uses the item events.

Worth knowing that this one is not new either. The example was moved verbatim from the README, which had it wrong, and the same wrong example is in the isElementRTL JSDoc at modules/react/common/lib/utils/isElementRTL.ts, lines 13 to 19. I have left that alone to keep this PR to docs. Happy to fix it here or in a follow-up, whichever you prefer.

Server-side rendering. Fair. The note now says the seed is only half of it: IDs are the seed plus an incrementing counter, so both sides must also start from the same count and generate in the same order, and useUniqueId is the thing to reach for since it uses React.useId() where available and depends on neither.

Good catch, and correct. Theming.mdx registers Features/Theming/Overview, so guides-theming--docs resolved to nothing. Fixed in ed5569dc, link text updated to match.

I checked the other five Storybook links in this PR against their Meta title while I was in there, and they are right: Guides/Testing and Guides/Accessibility/Overview for the two referenced from the Unique IDs page, and the three Hooks and Utilities/… IDs for the new and existing pages.
