createOfflineMiddleware

createOfflineMiddleware(config): object

Creates an offline middleware system for RTK Query mutations.

When the device is offline, configured mutation endpoints are queued instead of failing. When connectivity returns, queued mutations are replayed in order with LWW (Last-Writer-Wins) conflict detection via If-Unmodified-Since headers.

Usage:

const offline = createOfflineMiddleware({
  endpoints: ["postTodos", "patchTodosById", "deleteTodosById"],
  api: terrenoApi,
});

// Add to store:
// reducer: { offline: offline.offlineReducer }
// middleware: [..., offline.middleware]

Parameters

offlineReducer: Reducer<OfflineState>

offlineSlice

offlineSlice: Slice<OfflineState, { addConflict: void; clearConflicts: void; clearQueue: void; dequeue: void; dismissConflict: void; enqueue: void; setOnlineStatus: void; setSyncing: void; }, "offline", "offline", SliceSelectors<OfflineState>>
