Accessing a part of reducer state from one reducer within another reducer

Question

I do not know how to access a boolean isLoading flag from reducerForm.js reducer in reducerRegister.js. I have used combineReduc

Answer 1

A reducer cannot access another reducer's state, but if you're using redux-thunk you can do so from within an action creator. As an example, you can define an action creator like this:

export const someAction = () =>
  (dispatch, getState) => {
    const someVal = getState().someReducer.someVal;
    dispatch({ type: types.SOME_ACTION, valFromOtherReducer: someVal });
  };
