Convert TextArea component to TypeScript

This PR converts src/components/form-elements/text-area from JavaScript with Flow to TypeScript.

Changes

  • Converted TextArea.js to TextArea.tsx with exported TextAreaProps interface

  • Converted index.js to index.ts, re-exporting the component and its types

  • Converted TextArea.stories.js to TextArea.stories.tsx

  • Converted __tests__/TextArea.test.js to TextArea.test.tsx

  • Created .js.flow files for backward compatibility

  • Additionally removed redundant @ts-ignore comments in src/components path since its last component to migrate to TS.

Contract

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

Testing

  • Ran tests for src/components/form-elements/text-area; all 14 pass
  • yarn lint:ts and flow check pass

Summary by CodeRabbit

  • New Features

    • Added a configurable text-area form component with labels, placeholders, sizing, resizing, character limits, read-only, and disabled states.
    • Added required-field and custom validation with user-facing error messages.
    • Added controlled value handling and support for focus and styling options.
    • Added support for importing the text-area component and its configuration type.
    • Added improved handling for native validity and maximum-length constraints.
  • Tests

    • Updated text-area validation tests to reflect the component’s configuration and typing.

Walkthrough

The pull request adds a typed TextArea component with controlled values, native and custom validation, configurable rendering, exports, updated tests, and removal of obsolete type suppressions.

Changes

TextArea component

Layer / File(s) Summary
TextArea contracts and exports
src/components/form-elements/text-area/TextArea.tsx, src/components/form-elements/text-area/TextArea.js.flow, src/components/form-elements/text-area/index.*
Defines TextArea props, state, and error contracts. Exports the component from Flow and TypeScript entry points.
Value, validation, and rendering
src/components/form-elements/text-area/TextArea.*
Synchronizes controlled values, handles native and custom validation, clears custom validity before native fallback checks, forwards maxLength, and renders TextAreaCore through FormInput.
Validation coverage and story typing
src/components/form-elements/text-area/__tests__/TextArea.test.tsx, src/components/form-elements/text-area/TextArea.stories.tsx
Updates validity and instance casts in tests. Adds a string type to the story validator callback.
Type-suppression cleanup
src/components/context-menu/..., src/components/datalist-item/..., src/components/flyout/..., src/components/hotkeys/..., src/components/link/..., src/components/media/...
Removes obsolete TypeScript suppression comments and uses direct typed imports where applicable.

Merge Risk: 🔵 Low · up to 0d363

Consumers using the previously documented validation result forms may fail type checking after upgrading. Preserve the legacy types or explicitly document the breaking API change before merge.

In `@src/components/form-elements/text-area/TextArea.tsx`:
- Around line 132-146: In the fallback branch of the TextArea validation flow,
clear the textarea’s custom validity before calling
setErrorFromValidityState(textarea.validity), so native validity—including
required errors—can be evaluated correctly. Apply this change at
src/components/form-elements/text-area/TextArea.tsx lines 132-146 and
src/components/form-elements/text-area/TextArea.js.flow lines 123-136; both
sites require the same direct update.
- Around line 150-183: Update TextArea.tsx lines 150-183 and TextArea.js.flow
lines 141-174: destructure maxLength from props in each wrapper and forward it
as maxLength to TextAreaCore, preserving the existing rendering and validation
behavior.
- Around line 34-35: Align TextAreaProps.validation in TextArea.tsx and
TextArea.js.flow so both declarations return the same synchronous TextAreaError
object shape consumed by the TextArea runtime; remove unsupported string and
Promise result forms rather than adding normalization.

In `@src/components/form-elements/text-area/TextArea.tsx`:
- Around line 9-10: Update the validation callback result type used by TextArea
so code is required as a string in both TypeScript and Flow declarations, while
retaining optional code only on externally injected error types if needed.
Ensure checkValidity can pass error.code to setCustomValidity without allowing
validation results containing only message.

Inline comments:
In `@src/components/form-elements/text-area/TextArea.js.flow`:
- Around line 35-36: Update the validation prop contract and its handling
consistently: either preserve legacy string and Promise validation results by
including them in the Flow type and normalizing results before reading
error.code, or explicitly make this a breaking API change and update all
affected consumers. Anchor the changes to the validation prop declaration and
the synchronous validation calls in TextArea.js and the current TextArea
implementation.
