Type issue with union arguments for slice actions

[pdobrev]

We've been having issues upgrading TypeScript to 3.4 in a project that uses redux-starter-kit, so I gave v0.5.1 a try and noticed that the following code does not compile anymore:

import { createSlice, PayloadAction, configureStore } from 'redux-starter-kit';

type SceneID = 'main' | 'profile' | 'prefs';

const slice = createSlice({
  initialState: {
    scene: 'main' as SceneID,
  },
  reducers: {
    selectScene: (state, { payload }: PayloadAction<SceneID>) => {
      state.scene = payload;
    },
  },
});

const store = configureStore({
  reducer: slice.reducer,
});

store.dispatch(slice.actions.selectScene('profile'));

The error tsc gives is:

error TS2345: Argument of type '"profile"' is not assignable to parameter of type '"main" & "profile" & "prefs"'.
Type '"profile"' is not assignable to type '"main"'.

It seems that the argument type for the action was converted from a union to an intersection type.

The same code works with redux-starter-kit 0.4.3, but that one has other typing issues that prevent us from upgrading to TypeScript 3.4.

It seems that there is already a PR on this topic: #138

Just merged #138 , so closing this.
