Question 1

How do I add undo/redo to my Redux app?

Accepted Answer

Wrap your reducers with the undoable higher-order reducer from redux-undo, then use the provided ActionCreators to dispatch undo, redo, or jump actions. Check the examples in the README for quick starters.

Question 2

redux-undo vs redux-undo-actions: which should I use?

Accepted Answer

Redux-undo is more feature-rich with full history management and configuration, while redux-undo-actions is simpler but less maintained. For new projects, consider redux-undo's status and explore alternatives like Redux Toolkit's middleware options.

Question 3

How to limit the undo history size in redux-undo?

Accepted Answer

Set the 'limit' configuration option to a number when calling undoable(), which restricts the number of past states stored to prevent memory bloat, as shown in the Configuration section.

Question 4

Can I use redux-undo with Redux Toolkit?

Accepted Answer

Yes, but integration requires careful setup: wrap individual slice reducers with undoable in combineReducers, and ensure action types are configured to avoid conflicts with Redux Toolkit's default actions.

Question 5

How to filter out certain actions from the undo history?

Accepted Answer

Use the 'filter' configuration with helpers like includeAction or excludeAction, or define a custom function that returns true/false based on action type or state, as detailed in the Filtering Actions section.

Question 6

Is redux-undo still maintained in 2024?

Accepted Answer

No, the project is marked as not actively maintained in the README, with a call for volunteers. For production use, consider forks or alternative libraries to ensure long-term support.
