A waaay simpler redux, redux-thunk friendly setup for reducer, state and actions
import { getReducer, getState } from '../util/redux-util'
//default state
const defaultState = {
toggle: false
}
//reducer
const type = 'appReducer'
export const appReducer = getReducer(type, defaultState)
export const appState = getState(type)
//actions

Generate functions that are based on a similar structure by name - e.g. set redux state of UI components
//example functions to set redux state of UI components
const {setDrawerState, setDialogState, setPopoverState} = ['Drawer', 'Dialog', 'Popover'].map((name) => ({
['set' + name + 'State']: (state) => async (dispatch, getState) => {
const stateName = name.toLowerCase() + 'State'
const currentState = getState().appReducer[stateName]
dispatch({ type: 'UPDATE_UI_STATE', [stateName]: { ...currentState, ...state } })
}
})).reduce((a, c) => ({...a, ...c}))
export { setDrawerState, setDialogState, setPopoverState }
