Convert PillSelectorDropdown component to TypeScript

This PR converts src/components/pill-selector-dropdown from JavaScript with Flow to TypeScript.

Changes

  • Converted Pill, PillSelector, PillSelectorDropdown, PillSelectorDropdownField, RoundPill, SuggestedPill, and SuggestedPillsRow to .tsx with exported *Props interfaces
  • Converted helpers and filters (defaultDropdownRenderer, defaultInputParser, defaultDropdownFilter, waitForInputFilter) and flowTypes.js to TypeScript
  • Converted index.js to index.ts, re-exporting the existing runtime exports plus PillSelectorDropdownProps and PillSelectorDropdownFieldProps
  • Converted PillSelectorDropdown.stories.js to .tsx
  • Converted folder tests to .ts / .tsx
  • Created .js.flow stubs for remaining Flow consumers
  • types.ts now re-exports SuggestedPill as SuggestedPillType for existing TS importers

Contract

  • Declared Flow props contract preserved (requiredness, accepted values, defaults, exports)

Testing

  • Ran tests for src/components/pill-selector-dropdown; all 133 pass with snapshots matching previous output
  • yarn lint:ts and flow check pass

Summary by CodeRabbit

  • New Features

    • Added a pill selector dropdown for selecting, creating, validating, and removing pills.
    • Added support for comma-separated input, custom values, suggestions, avatars, rounded pills, and disabled states.
    • Added keyboard navigation, paste and IME composition handling, filtering, and accessible error messaging.
    • Added Formik integration for managing pill selections in forms.
  • Tests

    • Expanded coverage for parsing, filtering, rendering, avatar loading, and user interactions.

Walkthrough

The pull request adds or migrates the pill selector dropdown component family to TypeScript and Flow. It adds shared types, parsing and filtering utilities, pill rendering, keyboard interaction, suggestions, dropdown integration, Formik wiring, stories, exports, and test updates.

Changes

Pill selector dropdown

Layer / File(s) Summary
Pill primitives and utilities
src/components/pill-selector-dropdown/Pill*, src/components/pill-selector-dropdown/RoundPill*, src/components/pill-selector-dropdown/SuggestedPill*, src/components/pill-selector-dropdown/*Parser*, src/components/pill-selector-dropdown/filters/*, src/components/pill-selector-dropdown/types.ts
Typed pill components render state, avatar, removal, and suggestion behavior. Parsers and filters normalize input, remove duplicates, exclude selected options, and filter dropdown results.
PillSelector interaction and rendering
src/components/pill-selector-dropdown/PillSelector.*, src/components/pill-selector-dropdown/__tests__/PillSelector.test.tsx
PillSelector manages focus, keyboard navigation, selection removal, validation, accessibility attributes, pill variants, suggestions, and forwarded refs.
Dropdown parsing and event flow
src/components/pill-selector-dropdown/PillSelectorDropdown.*, src/components/pill-selector-dropdown/PillSelectorDropdown.stories.tsx, src/components/pill-selector-dropdown/__tests__/PillSelectorDropdown.test.tsx
PillSelectorDropdown handles parsing, custom-pill creation, blur, Enter, paste, composition, selection, validation, and integration with SelectorDropdown.
Formik integration and public exports
src/components/pill-selector-dropdown/PillSelectorDropdownField.*, src/components/pill-selector-dropdown/index.*, src/components/pill-selector-dropdown/__tests__/PillSelectorDropdownField.test.tsx
The Formik field connects selection and input events to field updates. Barrel modules export components, filters, and prop types. Tests use TypeScript helpers and cover forwarded events.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 8a70e

This migration can break pill-selector users providing legacy options, mishandle valid avatar identifiers, send invalid selections to callbacks, or leave Formik fields untouched. These compatibility and event-flow risks should be corrected before merge.

The hand-written Flow stubs declare narrower contracts than the TypeScript implementations they shadow. Each .js.flow file preserves the pre-migration Flow types, while the .ts/.tsx files widened the same parameters. Flow consumers therefore get type errors for input the runtime and the TypeScript contract both accept. Reconcile each stub with its implementation.

  • src/components/pill-selector-dropdown/filters/defaultDropdownFilter.js.flow#L19-L23: change selectedValues?: Array<Option> to selectedValues: ?Array<Option> in defaultDropdownFilter and in getDuplicatesFilter on Line 8, to match Array<Option> | null in defaultDropdownFilter.ts.
  • src/components/pill-selector-dropdown/PillSelector.js.flow#L42-L42: widen selectedOptions: List<Object> to accept a plain array, matching SelectedOptions in PillSelector.tsx, and update DefaultProps on Line 65 for the [] default on Line 79.
  • src/components/pill-selector-dropdown/defaultInputParser.js.flow#L24-L28: confirm the Flow Option keeps displayText required, because Line 27 calls displayText.replace(...) with no null check while flowTypes.ts declares displayText?: string.

- Around line 62-64: Update the onInput event unions in
PillSelectorDropdownProps and PillSelectorDropdown.handleInput to include
React.FormEvent<HTMLTextAreaElement>, matching the event forwarded by
PillSelector’s textarea handler while preserving the existing event types.
- Around line 232-233: Update handleSelect in PillSelectorDropdown to verify
selectedOption exists before invoking onSelect or onPillCreate. When the
selected index has no matching selector option, return without passing undefined
to either callback; preserve the existing callback behavior for valid
selections.

In `@src/components/pill-selector-dropdown/PillSelectorDropdownField.tsx`:
- Line 88: Update the dropdown reset path around handleBlur so events whose
target lacks target.name are normalized before Formik handling: pass no event or
replace them with createFakeEventTarget(name). Preserve normal named blur events
and ensure the reset still marks the correct field as touched.

In `@src/components/pill-selector-dropdown/RoundPill.tsx`:
- Line 90: Update the getPillImageUrl invocation in RoundPill so numeric
identifier 0 is accepted; replace the truthiness check on id with a
nullish-value check, while still skipping the callback when id is null or
undefined.

In `@src/components/pill-selector-dropdown/types.ts`:
- Line 47: Update the GetPillImageUrl type so its synchronous return branch also
permits null and undefined, matching the values accepted by
RoundPill.getAvatarUrl() and the existing Flow declaration; preserve the current
Promise-based return support.

19-23: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Widen the Flow selection types to accept null. The exported Flow filter and getDuplicatesFilter accept only Array<Option>, while the TypeScript implementation and existing tests use null for no selection. Add | null to both parameter types so Flow consumers can pass this supported value.

Guard id against only nullish values. Numeric IDs are supported, and PillSelector passes options to RoundPill. For id: 0, the truthiness check skips getPillImageUrl, leaves avatarUrl undefined, and passes no fetched URL to Avatar. Use id !== undefined && id !== null or an equivalent nullish check.

87-89: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not forward the synthetic reset event to Formik blur handling.

PillSelectorDropdown.handleSelect calls handleInput({ target: { value: '' } }) after a selection. That event has no target.name. handleBlur forwards it to Formik onBlur, so Formik cannot identify the field and does not mark it as touched. Call this.handleBlur() without the event when event.target has no name, so createFakeEventTarget(name) is used.

In `@src/components/pill-selector-dropdown/defaultInputParser.ts`:
- Line 22: Support legacy Option.text across all affected sites: in
src/components/pill-selector-dropdown/defaultInputParser.ts at line 22, match
against displayText ?? text ?? '' before replace; in
src/components/pill-selector-dropdown/filters/defaultDropdownFilter.ts at line
15, use the same fallback before toLowerCase; and in
src/components/pill-selector-dropdown/defaultDropdownRenderer.tsx at line 7,
render displayText ?? text so options with only text remain usable and visible.

In `@src/components/pill-selector-dropdown/PillSelectorDropdown.tsx`:
- Around line 231-237: In the selection handler around selectedOption, validate
that the lookup returned an option before invoking onSelect or onPillCreate.
Return early when selectedOption is undefined, and preserve the existing
callback behavior for valid options without relying on the Option casts to mask
missing entries.

In `@src/components/pill-selector-dropdown/PillSelectorDropdownField.tsx`:
- Around line 62-64: Update isValidOption to use the same displayText || text
fallback as pill rendering before trimming, so legacy options containing only
text and value remain valid without throwing when displayText is absent.
- Around line 87-89: Update the empty-text reset path in
PillSelectorDropdownField.handleInput to create the blur event target with
createFakeEventTarget, including the field name, before calling handleBlur.
Preserve the existing behavior for non-empty input and ensure Formik receives
target.name so touched state updates.
