Unable to access REDUX State in multple Pages and Components

I need some help figuring this issue out. After setting up Redux store and reducer in my app, I was able to successfully log and render updated state upon click in one, but not multiple pages. Below are steps and code sample:
Step1:
I installed Redux and wrapped the store around my entire app
// _app.js
import Layout from '../components/Layout';
import { SessionProvider } from 'next-auth/react';
import store from '../store';
import { Provider } from 'react-redux';
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';
function MyApp({ Component, pageProps: { session, ...pageProps } }) {
return (
<>
<Provider store={store}>
<SessionProvider session={session}>
<Layout>
<Component {...pageProps} />
<ToastContainer />
</Layout>
</SessionProvider>
</Provider>
</>
);
}
export default MyApp;
Step 2:
Setup an instance of a slice, Store and reducer
// mySlice.js
import { createSlice} from '#reduxjs/toolkit';
const initialState = {
user: {
role: ""
},
};
export const userStatusSlice = createSlice({
name: 'userStatus',
initialState,
reducers: {
userInfo: (state, action) => {
state.user.role = action.payload.role; // only this value comes from payload onClick
},
},
});
// Action creators are generated for each case reducer function
export const { userInfo } = userStatusSlice.actions;
export default userStatusSlice.reducer;
Step 3: Store...
//store.js
import { configureStore } from '#reduxjs/toolkit';
import userStatusSlice from './slices/userSlice/userStatus';
export default configureStore({
reducer: {
userStatus: userStatusSlice,
},
});
Step 4: Setup pages and React Hook useSelector, and tried accessing dispatched actions set as state variables in multiple pages. On one page I was able to fetch the data successfully, but not on the other page(s)
//First Page
import { useSession, getSession } from 'next-auth/react';
import { useSelector } from 'react-redux';
const firstPage = () => {
const { data: session } = useSession();
const { role } = useSelector((state) => state.userStatus.user);
console.log(role); // There is role successfully logged to the console
return (
<>
</>
);
};
export default firstPage;
//Second page.js
import { useSession } from 'next-auth/react';
import { useSelector } from 'react-redux';
const secondPage = () => {
const { data: session } = useSession();
const { role } = useSelector((state) => state.userStatus.user);
console.log(role) // There is NO role - why?
return (
<>
</>
);
};
export default secondPage;
I appreciate all input to help resolving this issue. Thanks in advance

Action not triggered in React/Redux

I'm new to redux and trying to fetch content from my BackEnd API. For some reason the action I call does not reach the reducer (It's not even executed). I first thought it was because it couldn't access the store since it is has a parent component but my Provider is well configured and there is another component at the same level, and just after i started thinking it was a problem with my dispatch but honestly i don't know. I have attached the code I feel is relevant and any contributions would be highly appreciated.
actions/viewers.js
import axios from 'axios';
import { VIEWERS_LOADED, VIEWERS_ERROR } from './types';
export const loadData = async (body, http) => {
const config = {
headers: {
'Content-Type': 'application/json',
},
};
try {
const res = await axios.post(
http,
body,
config
);
return res.data;
} catch (error) {
console.log(error);
}
};
export const extractConcurrentViewers = (from, to, aggregate) => async dispatch => {
console.log("CONCURRENT VIEWERS");
const body = {
session_token: localStorage.token,
from,
to,
};
try {
let aggregateConcur = null;
const graphConccur = await loadData(body, 'http://localhost:5000/audience');
console.log('extractViews -> res_1', graphConccur);
if (aggregate !== null) {
body.aggregate = aggregate
aggregateConcur = await loadData(body, 'http://localhost:5000/audience');
}
console.log('extractaggregateViewers -> res_2', aggregateConcur);
dispatch({
type: VIEWERS_LOADED,
payload: {
graphConccur,
aggregateConcur
},
});
} catch (error) {
console.log(error);
dispatch({
type: VIEWERS_ERROR,
});
}
}
reducers/viewers.js
import {
VIEWERS_LOADED,
VIEWERS_ERROR,
} from '../actions/types';
const initialState = {
session_token: localStorage.getItem('token'),
concurrence: null,
aggConcurrence: null,
};
export default function (state = initialState, action) {
const { type, payload } = action;
switch (type) {
case VIEWERS_LOADED:
return {
...state,
...payload,
concurrence: payload.graphConccur.audience,
aggConcurrence: payload.aggregateConcur.audience,
};
case VIEWERS_ERROR:
return {
...state,
concurrence: null,
aggConcurrence: null,
};
default:
return state;
}
}
reducer/index.js
import {combineReducers} from 'redux';
import alert from './alert';
import auth from './auth'
import profile from './profile'
import chart from './chart'
import viewers from './viewers'
export default combineReducers({
alert,
auth,
profile,
chart,
viewers
});
App.js
import React, { useEffect } from 'react';
import Navbar from './components/layout/Navbar';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

import Register from './components/auth/Register';
import Alert from './components/layout/Alert';
import Dashboard from './components/dashboard/Dashboard';
import PrivateRoute from './components/routing/PrivateRouting';
import { Provider } from 'react-redux';
import store from './store';
import { loadUser } from './actions/auth';
import setAuthToken from './utils/setAuthToken'
import './App.css';
if (localStorage.token) {
setAuthToken(localStorage.token);
}
const App = () => {
useEffect(() => {
store.dispatch(loadUser())
}, []);
return (
<Provider store={store}>
<Router>
<Navbar />
<Route exact path='/' component={Landing} />
<section className='container'>

<Route exact path='/register' component={Register} />
<PrivateRoute exact path='/dashboard' component={Dashboard} />
</Switch>
</section>
</Router>
</Provider>
);
};
export default App;
This is where the function extractConcurrentViewers is to be called and the component supposed to use that is <Concurrent concurrence={concurrence}/> and what is really weird about is that the component just above it is implemented almost the same way but it's working.
import React, { useEffect, Fragment } from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import Spinner from '../layout/Spinner';
import BandWidth from './BandWidth';
import Concurrent from './Concurrent';
import { extractCurrentClient } from '../../actions/profile';
import { extractchartData } from '../../actions/chart';
import { extractConcurrentViewers } from '../../actions/viewers';
const Dashboard = ({
extractCurrentClient,
extractchartData,
auth: { user },
profile: { profile, loading },
chart: { cdn, p2p, maxSum, maxCdn },
viewers: {concurrence}
}) => {
useEffect(() => {
extractCurrentClient();
extractchartData('max', 1585834831000, 1589118031000);
extractConcurrentViewers(1585834831000, 1589118031000);
}, []);
return loading && profile === null ? (
<Spinner />
) : (
<Fragment>
<h1 className='large text-primary'>Streaming</h1>
<p className='lead'>
<i className='fas fa-chart-line'></i>
Welcome {user && user.lname}
</p>
<BandWidth cdn={cdn} p2p={p2p} maxSum={maxSum} maxCdn={maxCdn} />
{/* <Concurrent concurrence={concurrence}/> */}
</Fragment>
);
};
Dashboard.propTypes = {
extractCurrentClient: PropTypes.func.isRequired,
extractchartData: PropTypes.func.isRequired,
extractConcurrentViewers: PropTypes.func.isRequired,
auth: PropTypes.object.isRequired,
profile: PropTypes.object.isRequired,
};
const mapStateToProps = (state) => ({
auth: state.auth,
profile: state.profile,
chart: state.chart,
viewers: state.viewers,
});
export default connect(mapStateToProps, {
extractCurrentClient,
extractchartData,
extractConcurrentViewers
})(Dashboard);
store.js
import { createStore, applyMiddleware } from 'redux';
import { composeWithDevTools } from 'redux-devtools-extension';
import thunk from 'redux-thunk';
import rootReducer from './reducers';
const initialState = {};
const middleware = [thunk];
const store = createStore(
rootReducer,
initialState,
composeWithDevTools(applyMiddleware(...middleware))
);
export default store;

You mapped extractConcurrentViewers to props in connect but did not add it to the destructured props object. Since they share the same name, that means is you're calling your action creator without it being bound to dispatch, so it will not be delivered to your reducers.
const Dashboard = ({
extractCurrentClient,
extractchartData,
auth: { user },
profile: { profile, loading },
chart: { cdn, p2p, maxSum, maxCdn },
viewers: {concurrence},
extractConcurrentViewers // <-- add this
}) => {
Personally I don't destructure my props and this is one reason. I prefer the code to be explicit about where values and functions are coming from props.extractConcurrentViewers . But that's my preference.

Using react redux with next.js

I try to use Redux with next.js starter project and I installed next-redux-wrapper on the project but I'm not sure where is the root file in this project.
I try to follow the tutorial shown on the next-redux-wrapper but had no success. Nothing change.
Please help me with how to add Redux to the project.
Regards.

Next.js uses the App component to initialize pages. You can override it and control the page initialization.
Although this demo is for next.js it should work for nextjs-starter.
install next-redux-wrapper:
npm install --save next-redux-wrapper
Add _app.js file to ./pages directory:
// pages/_app.js
import React from "react";
import {createStore} from "redux";
import {Provider} from "react-redux";
import App, {Container} from "next/app";
import withRedux from "next-redux-wrapper";
const reducer = (state = {foo: ''}, action) => {
switch (action.type) {
case 'FOO':
return {...state, foo: action.payload};
default:
return state
}
};
/**
* #param {object} initialState
* #param {boolean} options.isServer indicates whether it is a server side or client side
* #param {Request} options.req NodeJS Request object (not set when client applies initialState from server)
* #param {Request} options.res NodeJS Request object (not set when client applies initialState from server)
* #param {boolean} options.debug User-defined debug mode param
* #param {string} options.storeKey This key will be used to preserve store in global namespace for safe HMR
*/
const makeStore = (initialState, options) => {
return createStore(reducer, initialState);
};
class MyApp extends App {
static async getInitialProps({Component, ctx}) {
// we can dispatch from here too
ctx.store.dispatch({type: 'FOO', payload: 'foo'});
const pageProps = Component.getInitialProps ? await Component.getInitialProps(ctx) : {};
return {pageProps};
}
render() {
const {Component, pageProps, store} = this.props;
return (
<Container>
<Provider store={store}>
<Component {...pageProps} />
</Provider>
</Container>
);
}
}
export default withRedux(makeStore)(MyApp);
And then, actual page components can be simply connected:
This demo how to connect index.js in pages.
import Link from "next/link";
import React from "react";
import {
Container,
Row,
Col,
Button,
Jumbotron,
ListGroup,
ListGroupItem
} from "reactstrap";
import Page from "../components/page";
import Layout from "../components/layout";
import { connect } from "react-redux";
class Default extends Page {
static getInitialProps({ store, isServer, pathname, query }) {
store.dispatch({ type: "FOO", payload: "foo" }); // component will be able to read from store's state when rendered
return { custom: "custom" }; // you can pass some custom props to component from here
}
render() {
return (
<Layout>content...</Layout>
);
}
}
export default connect()(Default);
Refer to the documentation for more information: next-redux-wrapper

First i created simple next.js app with "npx create-next-app"
Then I created general redux setup in a folder called "store".
This is the folder structure
And in pages i have created an _app.js. Code inside it is like this-
Please let me know if anyone needs any help with setup...

this question needs update:
"next": "12.1.4",
"next-redux-wrapper": "^7.0.5",
"redux-devtools-extension": "^2.13.9",
"redux-thunk": "^2.4.1"
Create Store
import { createStore, applyMiddleware } from "redux";
import { HYDRATE, createWrapper } from "next-redux-wrapper";
import reducers from "./reducers/reducers";
import thunkMiddleware from "redux-thunk";
// middleware is an array
const bindMiddleware = (middleware) => {
if (process.env.NODE_ENV !== "production") {
const { composeWithDevTools } = require("redux-devtools-extension");
return composeWithDevTools(applyMiddleware(...middleware));
}
return applyMiddleware(...middleware);
};
// this is main reducer to handle the hydration
const reducer = (state, action) => {
// hydration is a process of filling an object with some data
// this is called when server side request happens
if (action.type === HYDRATE) {
const nextState = {
...state,
...action.payload,
};
return nextState;
} else {
// whenever we deal with static rendering or client side rendering, this will be the case
// reducers is the combinedReducers
return reducers(state, action);
}
};
const initStore = () => {
return createStore(reducer, bindMiddleware([thunkMiddleware]));
};
export const wrapper = createWrapper(initStore);
_app.js
import { wrapper } from "../redux/store";
function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
export default wrapper.withRedux(MyApp);
Using it with getServerSideProps
// sample action
import { getRooms } from "../redux/actions/roomActions";
import { wrapper } from "../redux/store";
export const getServerSideProps = wrapper.getServerSideProps(
(store) =>
// destructuring context obj
async ({ req, query }) => {
await store.dispatch(getRooms(req, query.page));
}
);

React-Auth0? Working! React-Redux-Auth0? I am losing my mind :/

This is a really long post, but I really need some help :/
I will be eternally grateful if someone would be able to help.
I have managed to get Auth0 working for an application i am working on with just react. It is an Overwatch SR tracker, and is essentially just a spreadsheet so I wasn't too concerned with protecting backend routes when I make them. There isn't any private information there.
My application state/props network became too complicated to manage, and through the process of implementing redux I simply cannot get it to work. I've been at it for three days, and I'm running out of ideas. Do I need Thunk with my current Auth setup to do this? I would imagine it is async since it needs to go get something that isnt there.
Granted I am a junior Dev, and dont have much experience with authentication. Can someone take a look at my working react application and guide me in the direction of what i may need to do to set it up with redux? I do have an understanding of redux flow, so if the proper method to do this was explained to me i feel i might get it.
here is some code:
my Auth.js file :
/*eslint no-restricted-globals: 0 */
import auth0 from "auth0-js";
import jwtDecode from 'jwt-decode';
const LOGIN_SUCCESS_PAGE = '/menu';
const LOGIN_FAILURE_PAGE = '/';
export default class Auth {
auth0 = new auth0.WebAuth({
domain: "redacted.auth0.com",
clientID: "redacted",
redirectUri: "http://localhost:3000/callback",
audience: "https://redacted.auth0.com/userinfo",
responseType: "token id_token",
scope: "openid profile"
});
constructor() {
this.login = this.login.bind(this);
}
login() {
this.auth0.authorize();
}
handleAuthentication() {
this.auth0.parseHash((err, authResults) => {
if (authResults && authResuslts.accessToken && authResults.idToken) {
let expiresAt = JSON.stringify((authResults.expiresIn) * 1000 + new Date().getTime());
localStorage.setItem("access_token", authResults.accessToken);
localStorage.setItem("id_token", authResults.idToken);
localStorage.setItem("expires_at", expiresAt);
location.hash = "";
location.pathname = LOGIN_SUCCESS_PAGE;
} else if (err) {
location.pathname = LOGIN_FAILURE_PAGE;
console.log(err);
}
});
}
isAuthenticated() {
let expiresAt = JSON.parse(localStorage.getItem('expires_at'));
return new Date().getTime() < expiresAt;
}
logout() {
localStorage.removeItem("access_token");
localStorage.removeItem("id_token");
localStorage.removeItem('expires_at');
location.pathname = LOGIN_FAILURE_PAGE;
}
getProfile() {
if (localStorage.getItem("id_token")) {
console.log(jwtDecode(localStorage.getItem("id_token")))
console.log(localStorage.getItem("id_token"));
return jwtDecode(localStorage.getItem("id_token"));
} else {
return {

<p>Hello there {this.props.user.nickname}! Sign in single click or email via Auth0 so we can save your results, and make the app usable by more than one person. I intend for more than one person to use this, so just to launch it and so the app knows your spreadsheet from someone elses I'll tie each user to their own UID. Feel free to come back, log in, and get your spreadsheet for the season back anytime.</p>
</div>
Go to the app menu!
<button onClick={() =>this.props.auth.getProfile()}>asdgkljsdngk</button>

);
}
}
my current HEADER.js component:
import React, { Component } from 'react';
export default class Header extends Component {
render() {
return (
<header className="header">
<h1 className='header__text'>SR TRACKER</h1>
{this.props.auth.isAuthenticated() ?
<button className='btn btn--logout' onClick={() => this.props.auth.logout()}>Logout</button>
:
<button className='btn btn--login' onClick={() => this.props.auth.login()}>Login or Sign Up</button>}
</header>
)
}
}
I simply want to map this authentication to a redux store instead to be consitent with the rest of my app (when redux is implemented) I have blown it away and started over multiple times, but a rough idea of what my redux flow might look like is like this template i use and have successfully implemented several times:
redux store:
import { createStore, compose, applyMiddleware } from 'redux';
import { createLogger } from 'redux-logger';
import thunk from 'redux-thunk';
import rootReducer from './reducers/rootReducer';
export default function configureStore(initialState) {
const middleware = [
createLogger({
collapsed: false,
duration: true,
diff: true,
}),
thunk,
];
const store = createStore(
rootReducer,
initialState,
compose(
applyMiddleware(...middleware),
window.devToolsExtension ? window.devToolsExtension() : format => format, // add support for Redux dev tools),
),
);
return store;
}
actionTypes.js in actions folder:
const actions = {
GET_FRIENDS: 'GET_FRIENDS',
REMOVE_FRIEND: 'REMOVE_FRIEND',
GET_MOVIES: 'GET_MOVIES',
GET_MOVIES_SUCCESS: 'GET_MOVIES_SUCCESS',
GET_MOVIES_FAILURE: 'GET_MOVIES_FAILURE',
DEVIN_FUN: 'DEVIN_FUN',
};
export default actions;
Sample actions page:
import axios from 'axios';
import actionTypes from './actionTypes';
export const getMoviesSuccess = data => {
return {
type: actionTypes.GET_MOVIES_SUCCESS,
data,
};
};
export const getMoviesFailure = () => {
return {
type: actionTypes.GET_MOVIES_FAILURE,
};
};
export const devinIsHavingFun = () => {
return {
type: actionTypes.DEVIN_FUN,
};
};
export const retrieveMovies = () => {
return function(dispatch) {
const API_KEY = 'trilogy';
dispatch(devinIsHavingFun());
axios
.get(`http://www.omdbapi.com?apikey=${API_KEY}&s=frozen`)
.then(data => {
dispatch(getMoviesSuccess(data.data.Search));
})
.catch(error => {
console.log(error);
dispatch(getMoviesFailure());
});
};
};
in the reducers folder wed have some files like initialState.js and root reducer that look like this respectively:
initialState.js:
export default {
friends: [],
movies: [],
};
rootReducer.js:
import { combineReducers } from 'redux';
import friends from './friendReducer';
import movies from './movieReducer';
const rootReducer = combineReducers({
friends,
movies,
});
export default rootReducer;
and a sample reducer:
import actionTypes from '../actions/actionTypes';
import initialState from './initialState';
export default function movieReducer(state = initialState.movies, action) {
switch (action.type) {
case actionTypes.GET_MOVIES_SUCCESS: {
return action.data;
}
default: {
return state;
}
}
}
I just dont know what to do. Do i need to use thunk? am I overthinking this? I'm pulling my hair out.
I also do connect my components in this fashion when redux is implemented :
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';
import * as friendActionCreators from './actions/friendActions';
import * as movieActionCreators from './actions/movieActions';
....................
function mapStateToProps(state) {
return {
myFriends: state.friends,
movies: state.movies,
};
}
function mapDispatchToProps(dispatch) {
return {
friendActions: bindActionCreators(friendActionCreators, dispatch),
movieActions: bindActionCreators(movieActionCreators, dispatch),
};
}
export default connect(mapStateToProps, mapDispatchToProps)(App);
Please let me know if anyone can point me in the right direction. thank you so much in advance.

preloadedState - session result overwritten by another reducer

I have a session reducer (using the redux-session library) which uses middleware to recover the state from the localstore. I can see from debugging tools that this is working as intended, however it is being replaced by my user reducer's initial state.
I feel I should be using preloadedState, but I cant get the result of a reducer into createStore?
storedState is being restored correctly (I can log it into console).
session: {user: {data: bhBSh}}, user: {data: null}
I cant see the best way to copy 'session' back to 'user' when the page is reloaded?
Session reducer:
function sessionReducer (state = {}, action) {
switch (action.type) {
case 'LOAD_STORED_STATE':
console.log(action.storedState); //Working!!!!!
return action.storedState;
default:
return state;
}
}
User reducer:
import { fromJS } from 'immutable';
import {
USER_LOGGING_IN,
USER_LOGGED_IN,
USER_LOGGED_OUT,
} from '../../constants';
const userInitialState = fromJS({
data: null,
isLoading: false,
});
function userReducer(state = userInitialState, action) {
switch (action.type) {
case USER_LOGGING_IN:
return state
.set('isLoading', true);
case USER_LOGGED_IN:
return state
.set('data', action.payload)
.set('isLoading', false);
case USER_LOGGED_OUT:
return userInitialState;
default:
return state;
}
}
export default userReducer;
export default function createReducer(injectedReducers) {
return combineReducers({
session: sessionReducer,
user: userReducer,
...injectedReducers,
});
}
configureStore:
export default function configureStore(history, session) {
session,
routerMiddleware(history),
thunkMiddleware
];
const enhancers = [
applyMiddleware(...middlewares),
];
//compose enhancers removed for readability
const store = createStore(
createReducer(),
//preloaded state??
composeEnhancers(...enhancers)
);
store.injectedReducers = {}; // Reducer registry
return store;
}

As you can see from redux-session docs, the only thing this library tries to do to restore saved state is dispatching LOAD_STORED_STATE (which can be customized) action. Restoring your state when the action is dispatched is up to you. The simplest way to restore user state is to handle this action in your userReducer, so that it will look something like:
function userReducer(state = userInitialState, action) {
switch (action.type) {
case LOAD_STORED_STATE:
return fromJS(action.storedState);
case USER_LOGGING_IN:
return state
.set('isLoading', true);
case USER_LOGGED_IN:
return state
.set('data', action.payload)
.set('isLoading', false);
case USER_LOGGED_OUT:
return userInitialState;
default:
return state;
}
}
