WalkthroughChangesSearchForm migration
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The migration preserves runtime behavior, but downstream TypeScript and Flow consumers may encounter compatibility or type-checking issues until the public config type and Flow declaration surface are aligned. The PR is otherwise mergeable with explicit owner follow-up. Possibly related PRs

1-2: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExport a props type that matches the exported component.
SearchFormPropsrequiresintland requiresaction,method,name,queryParams, anduseClearButton. The default export is typed asReact.ForwardRefExoticComponentoverSearchFormConfig, which omitsintland makes the default props optional. A consumer that annotates props withSearchFormPropscannot pass them to<SearchForm />without extra type work.Export the public config type as well, so consumers can describe the component's accepted props.
♻️ Proposed change
In
src/components/search-form/SearchForm.tsx, export the config type:-type SearchFormConfig = Omit<SearchFormProps, keyof SearchFormDefaultProps | 'intl'> & Partial<SearchFormDefaultProps>; +export type SearchFormConfig = Omit<SearchFormProps, keyof SearchFormDefaultProps | 'intl'> & + Partial<SearchFormDefaultProps>;Then re-export it from the barrel:
export { default } from './SearchForm'; -export type { SearchFormProps } from './SearchForm'; +export type { SearchFormConfig, SearchFormProps } from './SearchForm';🤖 Prompt for AI Agents

10-18: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winDerive the instance type from the component class instead of re-declaring it.
SearchFormInstancerestatesonChangeHandler,onClearHandler,searchInput, andsetInputRef. The declaredonChangeHandlersignature is(event: { target: { value: string | null } }) => void, but the implementation signature is(event: React.FormEvent<HTMLFormElement>) => void. The shim therefore does not track the real contract. If a handler signature changes inSearchForm.tsx, these tests still compile.Export
SearchFormBasefromSearchForm.tsxand type the helper asInstanceType<typeof SearchFormBase>. The tests then fail at compile time when the instance API changes.♻️ Proposed change
