Revert commit 6849141 Replace interface inheritance pattern with explicit type definitions to ensure TypeScript declarations bundle correctly. The StacHook base interface was causing vite-plugin-dts to generate incomplete type declarations where inherited properties (isLoading, isFetching, error) were not visible to library consumers. Changes: - Remove StacHook interface and StacRefetchFn<T> from src/types/index.d.ts - Convert all hook return types from interface inheritance to explicit types - Add all properties directly to each hook type definition - Fix error type coercion in useStacSearch (undefined → null) - Fixes "Property 'isLoading' does not exist" errors in consuming projects

could extend with types too like
type StacHook = {
isLoading: boolean;
isFetching: boolean;
error: ApiError | null;
};
type StacCollectionHook = {
refetch: () => Promise<QueryObserverResult<Collection, ApiError>>;
} & StacHook

It is possible to keep this pattern and have the types correctly exported. Was there any reason not to?

The error is already null. Why is this needed?

@sandrahoang686 @AliceR Made a proposal fix in this PR (#45) that doesn't remove the inheritance and reduced duplication. |
