In Redux Toolkit, you can listen to every dispatched action globally by using middleware or by using the addMatcher function inside a slice’s extraReducers with a universal matcher like isAnyOf() or custom predicate functions.

Ways to Listen to Actions Globally

1
Use custom middleware to intercept every dispatched action and perform side effects or logging.
2
Use builder.addMatcher() in createSlice() to handle groups of actions based on conditions.
3
Integrate listener middleware (createListenerMiddleware) to respond to specific or all actions declaratively.

Example 1: Using Custom Middleware

Example 2: Using Listener Middleware (RTK Built-in)

Using createListenerMiddleware is the most modern and recommended approach in Redux Toolkit, as it cleanly separates side effects from reducers and allows reacting to any action in a declarative way.
