Once the user exits the system, do multiple clear functions called still?
For example, the state of the user and his/hers cats needs to be flushed during the logout process. The code would be:
const usersDefaultState = [];
const users = (state = usersDefaultState, { type, payload }) => {
switch (type) {
case "RESET_USER":
return usersDefaultState;
case "ADD_USER":
return [...state, payload];
default:
return state;
}
};
const catsDefaultState = [];
const cats = (state = catsDefaultState, { type, payload }) => {
switch (type) {
case "RESET_CATS":
return catsDefaultState;
case "ADD_CATS":
return [...state, payload];
default:
return state;
}
};Regarding DRY principle, is it possible to reset the redux state using the root reducer? The answer is yes. Let’s checkout the code:
// configureStore.js
const appReducer = createAppReducer();
const rootReducer = (state, action) => {
let currentState = state;
if (action.type === 'LOGOUT_SUCCEEDED') {
currentState = undefined;
}
return appReducer(currentState, action);
};
// Execute it in saga
yield put({ type: 'LOGOUT_SUCCEEDED' });Additionally, the isolation clear actions can still exit in each reducer. The Redux state can be cleaned up partially and entirely.
