Modify action in ListenerMiddleware

[medihack]

Is it possible to modify an action in a ListenerMiddleware (in my case, attach some meta property)?

I tried it with something like below, but the action received by the reducer does not have the attached property.

listenerMiddleware.startListening({
  matcher: isAnyOf(action1, action2, action3),
  effect: (action, listenerApi) => {
    action.meta = { foo: "bar" }
  },
})

Is a ListenerMiddleware not suitable for that and I have to use some more general Redux middleware?

listeners will always run after the action has already reached the reducers, so it's not possible to modify the action in them.

Ok, good to know. I will use a "normal" middleware then. Thanks for helping out again!
