From bd81cc47601b6cc06c718a49f67587088f0fc436 Mon Sep 17 00:00:00 2001 From: johndoe6345789 Date: Fri, 23 Jan 2026 18:09:55 +0000 Subject: [PATCH] feat(redux): phase 2 task 2 - api-clients delegates to Redux hooks Migrated @metabuilder/api-clients to delegate all async operations to Redux-backed implementations via @metabuilder/hooks-async. Maintains 100% backward compatibility. Changes: - useAsyncData: delegates to useReduxAsyncData - usePaginatedData: delegates to useReduxPaginatedAsyncData - useMutation: delegates to useReduxMutation All type signatures and return values unchanged. Error handling converts Redux error strings to Error objects for backward compatibility. Pagination state converts between 0-based (public API) and 1-based (Redux) page numbers automatically. No breaking changes - all consumers (codegen, nextjs, qt6, workflowui) can continue using @metabuilder/api-clients without modifications.
