Next.js withRouter not always updating the page - next.js

I have a problem with my next.js app. It seems that when the same component gets rendered twice, it does not update the url properly.
I have a main component wrapper that goes around everything:
import React from "react"
import "babel-polyfill"
import root from "window-or-global"
import { withRouter } from "next/router"
import commonApi from "./../../common/common"
import AppLayout from "./../../components/main/AppLayoutWrapper"
import configureStore from "./../../redux/configureStore"
import routes from "./../../../server/routes/routes"
const { makeWithRedux } = configureStore
const { Router } = routes
const { getRequestAreaInformation } = commonApi
let store = null
const MainWrapper = (Page: React$Node) => {
const PageWrapper = class PageWrapper extends React.Component<{}> {
static async getInitialProps(req: any) {
return getRequestAreaInformation(req)
}
// Required to make the components work on page load, but fragile
componentDidMount() {
this.props.actions.urlLocationChanged(this.props.router)
}
render() {
this.props.actions.urlLocationChanged(this.props.router)
if (Page.getInitialProps) {
Promise.resolve(Page.getInitialProps({ ...this.props })).then(() => {})
}
if (AppLayout.getInitialProps) {
Promise.resolve(AppLayout.getInitialProps({ ...this.props })).then(() => {})
}
return (
<section className="main-wrapper-jsx">
<AppLayout {...this.props}>
<Page {...this.props} />
</AppLayout>
</section>
)
}
}
return withRouter(makeWithRedux(PageWrapper))
}
export default MainWrapper
The routes file links up to this:
const link = require("next/link")
const router = require("next/router")
const NextRouter = router.default || router
const NextLink = link.default || link
const routes = require("next-routes")({
Router: NextRouter,
Link: NextLink,
})
const MediaListView = "MediaListView"
const AuthView = "auth/AuthView"
const LibraryView = "LibraryView"
routes
.add("root", "/", LibraryView)
.add("home", "/home", LibraryView)
.add("search", "/search", MediaListView)
.add("login", "/login", AuthView)
.add("register", "/register", AuthView)
module.exports = routes
Then finally, there's the redux store that implements this action.
import { handleActions, createAction } from "redux-actions"
import { fromJS, toJS } from "immutable"
import root from "window-or-global"
const initialState = fromJS({
asPath: "",
pathname: "",
query: {},
route: "",
})
const urlLocationChanged = createAction(`${routeParams.URL_LOCATION_CHANGED}`, (url) => {
return url
})
const actions = {
urlLocationChanged,
}
const routeActions = handleActions(
{
URL_LOCATION_CHANGED: (state, {payload}) => {
const location = payload
const pathname = decodeURIComponent(location.asPath.slice(1))
let param = pathname
if (param && param.match(/\w+\D/)) {
param = param.match(/\w+\D/)[0]
}
return state
.set("location", location)
}
return state.set("location", location)
},
},
initialState,
)
export default {
initialState,
routeActions,
actions,
}
All of this should work, but whenever there's two clicks on the same object, let's say someone clicks on login and then clicks on register, nothing happens.

i tried to reinstall redux and react-redux but didnt helped.
also tried Remove the node_modules
Remove package-lock.json

useEffect hook problem, use redux to get data from backend to frontend

Hello i am new to programming, and i have learn to use MERN to make a sign up,i have no issue with backend but when i tried to use redux ,i have this problem in the frontend
enter image description here
This is the code for the SignInScreen.js
import React, { useEffect, useState } from 'react'
import { useDispatch, useSelector } from 'react-redux'
import { Link, useLocation, useNavigate } from 'react-router-dom'
import { login } from '../actions/userAction'
export const SignInScreen = (props, history) => {
const navigate = useNavigate
const [email, setEmail] = useState('')
const [password, setPassword] = useState('')
const submitHandler = (e) => {
e.preventDefault()
dispatch(login(email, password))
}
const { search } = useLocation()
const redirectInUrl = new URLSearchParams(search).get('redirect')
const redirect = redirectInUrl ? redirectInUrl : '/'
const userlogin = useSelector((state) => state.userlogin)
const { userInfo, loading, error } = userlogin
const dispatch = useDispatch()
useEffect(() => {
if (userInfo) {
navigate(redirect)
}
}, [navigate, userInfo, redirect])
I dont know what wrong with the code,but i do know that it connected with the redux store which have reducer,action and constant..this is for the redux store.js
import { createStore, combineReducers, applyMiddleware, compose } from 'redux'
import thunk from 'redux-thunk'
import {
userLoginReducer,
} from './reducers/userReducer'
const userInfo = localStorage.getItem('userInfo')
? JSON.parse(localStorage.getItem('userInfo'))
: null
const initialState = {
userLogin: { userInfo },
}
const reducer = combineReducers({
userLogin: userLoginReducer,
})
const middleware = [thunk]
const store = createStore(
reducer,
initialState,
compose(applyMiddleware(...middleware))
)
export default store
This is for constant
export const USER_LOGIN_REQUEST = 'USER_LOGIN_REQUEST'
export const USER_LOGIN_SUCCESS = 'USER_LOGIN_SUCCESS'
export const USER_LOGIN_FAIL = 'USER_LOGIN_FAIL'
export const USER_LOGOUT = 'USER_LOGOUT'
this is userReducer.js
import {
USER_LOGIN_REQUEST,
USER_LOGIN_SUCCESS,
USER_LOGIN_FAIL,
USER_LOGOUT,
} from '../constants/userConstant'
function userLoginReducer(state = {}, action) {
switch (action.type) {
case USER_LOGIN_REQUEST:
return { loading: true }
case USER_LOGIN_SUCCESS:
return { loading: false, userInfo: action.payload }
case USER_LOGIN_FAIL:
return { loading: false, error: action.payload }
case USER_LOGOUT:
return {}
default:
return state
}
}
export userLoginReducer
and lastly for user.js
import Axios from 'axios'
import {
USER_LOGIN_REQUEST,
USER_LOGIN_SUCCESS,
USER_LOGIN_FAIL,
} from '../constants/userConstant'
const login = (email, password) => async (dispatch) => {
try {
dispatch({ type: USER_LOGIN_REQUEST })
const config = { headers: { 'Content-Type': 'application/json' } }
const { data } = await Axios.post(
'/api/users/login',
{ email, password },
config
)
dispatch({ type: USER_LOGIN_SUCCESS, payload: data })
localStorage.setItem('userInfo', JSON.stringify(data))
} catch (error) {
dispatch({
type: USER_LOGIN_FAIL,
payload:
error.response && error.response.data.message
? error.response.data.message
: error.message,
})
}
}
export login
I just want to get the data into the userInfo but it dont recognized them and said it is a TypeError..I hope u can help me with this..im using the redux latest version
The problem is in userLoginReducer. Each reducer should return a complete new copy of the store.
If you return just the changes, the object you return replaces the entire state.
For example in this code:
switch (action.type) {
case USER_LOGIN_REQUEST:
return { loading: true };
}
The state { userLogin: { userInfo } } will be replaced with { loading: true }. Then you will not have userLogin anymore in the state. That's why you get the error.
To overcome this problem, spread the previous state in returned object (for all actions):
switch (action.type) {
case USER_LOGIN_REQUEST:
return { ....state, loading: true }; // ...state copies exist state to the new copy of state
}
Note: To easily solve similar bugs in the future, I recommend to use redux devtools extension. It is a great extension for debugging and look at changes in redux store.
I have tried that but still cannot fix my problem,this is the rest of my signinScreen,js
import React, { useEffect, useState } from 'react'
import { useDispatch, useSelector } from 'react-redux'
import { Link, useLocation, useNavigate } from 'react-router-dom'
import { login } from '../actions/userAction'
export const SignInScreen = (props, history) => {
const navigate = useNavigate
const [email, setEmail] = useState('')
const [password, setPassword] = useState('')
const submitHandler = (e) => {
e.preventDefault()
dispatch(login(email, password))
}
const { search } = useLocation()
const redirectInUrl = new URLSearchParams(search).get('redirect')
const redirect = redirectInUrl ? redirectInUrl : '/'
const userlogin = useSelector((state) => state.userlogin)
const { userInfo, loading, error } = userlogin
const dispatch = useDispatch()
useEffect(() => {
if (userInfo) {
navigate(redirect)
}
}, [navigate, userInfo, redirect])
return (
<Container className="small-container">
<h1 className="my-3">Sign In</h1>
<Form onSubmit={submitHandler}>
<Form.Group className="mb-3" controlId="email">
<Form.Label>Email</Form.Label>
<Form.Control
type="email"
required
onChange={(e) => setEmail(e.target.value)}
/>
</Form.Group>
<Form.Group className="mb-3" controlId="password">
<Form.Label>Password</Form.Label>
<Form.Control
type="password"
required
onChange={(e) => setPassword(e.target.value)}
/>
</Form.Group>
<div className="mb-3">
<Button type="submit">Sign In</Button>
</div>
<div className="mb-3">
New Customer?{' '}
<Link to={`/signup?redirect=${redirect}`}>Create new account</Link>
</div>
</Form>
</Container>
)
}
it still show the same error like before,i have no idea to solve this

Next.js: How to use useState and AuthContext without invalidating SSG html

I have an AuthContext to manage the authentication in my Next.js app. The _app.js file looks like this:
import '../styles/global.css'
import 'tailwindcss/tailwind.css'
import { AuthProvider } from '../components/AuthContext'
function MyApp({ Component, pageProps }) {
return (
<>
<AuthProvider>
<Component {...pageProps} />
</AuthProvider>
</>
)
}
export default MyApp
And the AuthContext file is something like this:
import React, { useContext, useState, useEffect } from "react"
import { auth, db } from "./Firebase";
import { doc, getDoc } from "firebase/firestore";
const AuthContext = React.createContext()
export function AuthProvider({ children }) {
const [currentUser, setCurrentUser] = useState([])
const [loading, setLoading] = useState(true)
const [userData, setUserData] = useState({})
const [companyData, setCompanyData] = useState({})
useEffect(() => {
const unsubscribe =
auth.onAuthStateChanged(user => {
setCurrentUser(user)
setLoading(false)
})
return unsubscribe
}, [])
useEffect(() => {
const fetchData = async () => {
const qu = doc(db, "users", currentUser.uid)
const datau = await getDoc(qu)
setUserData(datau.data());
const qc = doc(db, "companies", currentUser.uid)
const datac = await getDoc(qc)
setCompanyData(datac.data());
}
currentUser?.uid && fetchData()
}, [currentUser])
const value = {
currentUser,
userData,
companyData
}
return (
<AuthContext.Provider value={value}>
{!loading && children}
</AuthContext.Provider>
)
}
export function useAuth() {
return useContext(AuthContext)
}
Then I have a dynamic page [id].js that is something like this:
import { useAuth } from '../../components/AuthContext';
import Head from 'next/head';
export async function getStaticProps(context) {
// fetch and return data
}
export async function getStaticPaths() {
// fetch paths
return { paths, fallback: 'blocking' }
}
export default function Job(props) {
const { userData, currentUser } = useAuth();
const data = props.data;
return (
<>
<Head>
{data.title} | SiteName
</Head>
<h1>data.title</h1>
{currentUser ? userData.name : null}
</>
)
}
Problem: The website works perfectly, BUT when I check the page [id].js source code, Next.js doesn't build the HTML structure with head and body optimized for SEO (which is the main reason why I'm migrating to Next.js).
If I remove the "!loading &&" (see below) in the AuthContext file, the Next's SSG HTML generation works BUT the whole app starts to give me errors everywhere.
<AuthContext.Provider value={value}>
{children}
</AuthContext.Provider>
What exactly is the problem? And any idea on how to solve it?

Nextjs dynamic routes with next-i18next build error

I have an edit page that will be rendered with an id parameter and it works fine when application is running but while building the nextjs app I get this error
[Error: ENOENT: no such file or directory, rename 'C:\Users\Ahsan Nisar\Documents\GitHub\customer-portal\frontend.next\export\en\companies\edit[id].html' -> 'C:\Users\Ahsan Nisar\Documents\GitHub\customer-portal\frontend.next\server\pages\en\companies\edit[id].html']
the full error
I am not sure what this error is related to or what mistake am I making in my code that this error is occuring during build time.
Here is the code of my page
import { WithAuthorization } from 'common/roq-hocs';
import { MainLayout } from 'layouts';
import { useTranslation } from 'next-i18next';
import { serverSideTranslations } from 'next-i18next/serverSideTranslations';
import React, { FunctionComponent } from 'react';
import { CompaniesEditView } from 'views/companies-edit';
const CompanyCreatePage: FunctionComponent = () => {
const { t } = useTranslation('companiesEdit');
return (
<MainLayout title={t('title')}>
<WithAuthorization
permissionKey="companies.update"
failComponent={
<div className="mt-16 text-2xl text-center text-gray-600">
<span>{t('noView')}</span>
</div>
}
>
<CompaniesEditView />
</WithAuthorization>
</MainLayout>
);
};
export const getStaticProps = async ({ locale }) => ({
props: {
...(await serverSideTranslations(locale, ['common', 'companiesEdit'])),
},
});
export const getStaticPaths = () => ({
paths: ['/companies/edit/[id]'],
fallback: true,
});
export default CompanyCreatePage;
I think that the problem might be that you are not returning the expected paths model in getStaticPaths function.
Minimal example of this page:
import { GetStaticPaths, GetStaticProps } from 'next';
import { useRouter } from 'next/router';
const CompanyCreatePage = () => {
const router = useRouter();
const { id } = router.query;
return (
<div>
<h1>Company Create Page Content for id: {id}</h1>
</div>
);
};
export const getStaticPaths: GetStaticPaths = async () => {
// Get all possible 'id' values via API, file, etc.
const ids = ['1', '2', '3', '4', '5']; // Example
const paths = ids.map(id => ({
params: { id },
}));
return { paths, fallback: false };
};
export const getStaticProps: GetStaticProps = async context => {
return { props: {} };
};
export default CompanyCreatePage;
Then, navigating to the page /users/edit/3/ returns the following content
Take into account that the fallback param in getStaticPaths changes the behavior of getStaticProps function. For reference, see the documentation

"Cannot read property of undefined" being thrown by react-apollo used with React-NextJS

My NextJS project has been giving me grief over Graph QL these days. I've been trying to implement an Apollo client solution to retrieve data from a remote GraphQL server into a custom component. But no matter which solution I try, I always end up with this error. Here's my current react-apollo implementation:
// /lib/with-apollo-client.js
import React from "react";
import Head from "next/head";
import { getDataFromTree } from "react-apollo";
import initApollo from "./init-apollo";
export default App => {
return class WithData extends React.Component {
static displayName = `WithData(${App.displayName})`;
static async getInitialProps(ctx) {
const { Component, router } = ctx;
const apollo = initApollo({});
ctx.ctx.apolloClient = apollo;
let appProps = {};
if (App.getInitialProps) {
appProps = await App.getInitialProps(ctx);
}
// Run all GraphQL queries in the component tree
// and extract the resulting data
if (!process.browser) {
try {
// Run all GraphQL queries
await getDataFromTree(
<App
{...appProps}
Component={Component}
router={router}
apolloClient={apollo}
/>
);
} catch (error) {
console.error("Error while running `getDataFromTree`", error);
}
// getDataFromTree does not call componentWillUnmount
// head side effect therefore need to be cleared manually
Head.rewind();
}
// Extract query data from the Apollo store
const apolloState = apollo.cache.extract();
return {
...appProps,
apolloState
};
}
constructor(props) {
super(props);
this.apolloClient = initApollo(props.apolloState);
}
render() {
return <App {...this.props} apolloClient={this.apolloClient} />;
}
};
};
// /lib/init-apollo.js
import { ApolloClient, InMemoryCache, HttpLink } from 'apollo-boost'
import fetch from 'isomorphic-unfetch'
let apolloClient = null
// Polyfill fetch() on the server (used by apollo-client)
if (!process.browser) {
global.fetch = fetch
}
function create (initialState) {
// Check out https://github.com/zeit/next.js/pull/4611 if you want to use the AWSAppSyncClient
return new ApolloClient({
connectToDevTools: process.browser,
ssrMode: !process.browser, // Disables forceFetch on the server (so queries are only run once)
link: new HttpLink({
uri: 'https://api.graph.cool/simple/v1/cixmkt2ul01q00122mksg82pn', // Server URL (must be absolute)
credentials: 'same-origin' // Additional fetch() options like `credentials` or `headers`
}),
cache: new InMemoryCache().restore(initialState || {})
})
}
export default function initApollo (initialState) {
// Make sure to create a new client for every server-side request so that data
// isn't shared between connections (which would be bad)
if (!process.browser) {
return create(initialState)
}
// Reuse client on the client-side
if (!apolloClient) {
apolloClient = create(initialState)
}
return apolloClient
}
The component I'm retrieving data into looks like this:
// /components/PostsList2.jsx
import { Query } from 'react-apollo'
import gql from 'graphql-tag'
export const allUsersQuery = gql`
query allUsers($first: Int!, $skip: Int!) {
allUsers(orderBy: createdAt_DESC, first: $first, skip: $skip) {
id
firstName
createdAt
}
_allUsersMeta {
count
}
}
`
export const allUsersQueryVars = {
skip: 0,
first: 10
}
export default function PostsList2 () {
return (
<Query query={allUsersQuery} variables={allUsersQueryVars}>
{({ loading, error, data: { allUsers, _allUsersMeta }, fetchMore }) => {
if (error) return <aside>Error loading users!</aside>
if (loading) return <div>Loading</div>
const areMorePosts = allUsers.length < _allUsersMeta.count
return (
<section>
<ul>
{allUsers.map((user, index) => (
<li key={user.id}>
<div>
<span>{index + 1}. </span>
<div>{user.firstName}</div>
</div>
</li>
))}
</ul>
{areMorePosts ? (
<button onClick={() => loadMorePosts(allUsers, fetchMore)}>
{' '}
{loading ? 'Loading...' : 'Show More'}{' '}
</button>
) : (
''
)}
</section>
)
}}
</Query>
)
}
function loadMorePosts (allUsers, fetchMore) {
fetchMore({
variables: {
skip: allUsers.length
},
updateQuery: (previousResult, { fetchMoreResult }) => {
if (!fetchMoreResult) {
return previousResult
}
return Object.assign({}, previousResult, {
// Append the new users results to the old one
allUsers: [...previousResult.allUsers, ...fetchMoreResult.allUsers]
})
}
})
}
Since this is a NextJS project, there's also an _app.jsx that I've wrapped in a special provider component:
// /pages._app.jsx
/* eslint-disable max-len */
import '../static/styles/fonts.scss';
import '../static/styles/style.scss';
import '../static/styles/some.css';
import CssBaseline from '#material-ui/core/CssBaseline';
import { ThemeProvider } from '#material-ui/styles';
import jwt from 'jsonwebtoken';
import withRedux from 'next-redux-wrapper';
import App, {
Container,

import Head from 'next/head';
import React from 'react';
import { Provider } from 'react-redux';
import makeStore from '../reducers';
import mainTheme from '../themes/main-theme';
import getSessIDFromCookies from '../utils/get-sessid-from-cookies';
import getLanguageFromCookies from '../utils/get-language-from-cookies';
import getUserTokenFromCookies from '../utils/get-user-token-from-cookies';
import removeFbHash from '../utils/remove-fb-hash';
import withApolloClient from '../lib/with-apollo-client'
import { ApolloProvider } from 'react-apollo'
class MyApp extends App {
static async getInitialProps({ Component, ctx }) {
let userToken;
let sessID;
let language;
if (ctx.isServer) {
ctx.store.dispatch({ type: 'UPDATEIP', payload: ctx.req.headers['x-real-ip'] });
userToken = getUserTokenFromCookies(ctx.req);
sessID = getSessIDFromCookies(ctx.req);
language = getLanguageFromCookies(ctx.req);
const dictionary = require(`../dictionaries/${language}`);
ctx.store.dispatch({ type: 'SETLANGUAGE', payload: dictionary });
if(ctx.res) {
if(ctx.res.locals) {
if(!ctx.res.locals.authenticated) {
userToken = null;
sessID = null;
}
}
}
if (userToken && sessID) { // TBD: validate integrity of sessID
const userInfo = jwt.verify(userToken, process.env.JWT_SECRET);
ctx.store.dispatch({ type: 'ADDUSERINFO', payload: userInfo });
}
ctx.store.dispatch({ type: 'ADDSESSION', payload: sessID }); // component will be able to read from store's state when rendered
}
const pageProps = Component.getInitialProps ? await Component.getInitialProps(ctx) : {};
return { pageProps };
}
componentDidMount() {
// Remove the server-side injected CSS.
const jssStyles = document.querySelector('#jss-server-side');
if (jssStyles) {
jssStyles.parentNode.removeChild(jssStyles);
}
// Register serviceWorker
if ('serviceWorker' in navigator) { navigator.serviceWorker.register('/serviceWorker.js'); }
// Handle FB's ugly redirect URL hash
removeFbHash(window, document);
}
render() {
const { Component, pageProps, store, apolloClient } = this.props;
return (
<Container>
<Head>
// redacted for brevity
</Head>
<ThemeProvider theme={mainTheme}>
{/* CssBaseline kickstart an elegant, consistent, and simple baseline to build upon. */}
<CssBaseline />
<ApolloProvider client={apolloClient}>
<Provider store={store}>
<Component {...pageProps} />
</Provider>
</ApolloProvider>
</ThemeProvider>
</Container>
);
}
}
export default withApolloClient(withRedux(makeStore)(MyApp));
So with this setup, when I compile and run my app, it throws the following:
TypeError: Cannot read property 'allUsers' of undefined
I'm really lost! The repo is up at https://github.com/amitschandillia/proost/tree/master/web.
