How do you create custom actions not tied to a slice?

Difficulty: 6/10

Redux Toolkit, extraReducers, createAction

In Redux Toolkit, you can create actions that are not directly associated with a slice by using the createAction utility. This is useful when actions are shared across multiple slices or handled only by extra reducers.

When to Use createAction

1
When multiple slices need to respond to the same action.
2
When you want a standalone action not tied to any slice logic.
3
When using createReducer or extraReducers to handle shared updates.

Example: Defining and Using a Custom Action

Here, resetTodos is a standalone action that can be dispatched anywhere in the app. It’s not defined inside a slice but can still be handled by reducers or extraReducers as part of other slices.
