To implement undo/redo history for an AsyncRedux store, you record state snapshots through a StateObserver. You must initialize an observer, register it with the store, and dispatch UndoAction and RedoAction to navigate historical states.

Yes, you can perform partial-state undo/redo to navigate a specific subset of state instead of the entire application state. This allows targeted reversion of specific slices while leaving the rest of the current state untouched.

When you dispatch a new action after an undo, the redo history is automatically cleared. This prevents conflicting state branches by discarding future state entries that were previously navigated away from.

You can configure history limits to restrict the number of state snapshots recorded by the StateObserver. This prevents excessive memory consumption by capping the number of historical states stored during the application lifecycle.

Yes, implementing a StateObserver is required to capture state transitions after each successful dispatch. It serves as the core mechanism to record snapshots and enable navigation through full or partial historical states.

A StateObserver records state transitions by capturing snapshots after each successful dispatch action. By registering this observer with the Store, it continuously monitors and saves the evolving state needed for undo and redo operations.
