I created a component in my project that consists of a simple button that returns to the previous page, using useNavigate hook.
As it is written in the documentation, just passing -1 as a parameter to the hook would be enough to go back one page. But nothing happens.
The component code:
import { useNavigate } from 'react-router-dom'
import './go-back.styles.scss'
const GoBack = () => {
const navigate = useNavigate()
const handleClick = () => {
navigate(-1)
}
return (
<button
className='go-back'
onClick={handleClick}
>
go back
</button>
)
}
export default GoBack
The app.js code:
import { lazy, Suspense } from 'react'
import { Routes, Route } from 'react-router-dom'
import Header from '../components/header/header.component'
import Footer from '../components/footer/footer.component'
import './App.scss'
const App = () => {
const HomePage = lazy(() => import('../pages/home/home.page'))
const SearchPage = lazy(() => import('../pages/search/search.page'))
const MostraPage = lazy(() => import('../pages/mostra/mostra.page'))
const AuthPage = lazy(() => import('../pages/auth/auth.page'))
const AccountPage = lazy(() => import('../pages/account/account.page'))
const PrenotaPage = lazy(()=> import('../pages/prenota/prenota.page'))
const SectionPage = lazy(() => import('../pages/section/section.page'))
return (
<div className='app'>
<Header />
<Suspense fallback={<span>Loading...</span>}>
<Routes>
<Route exact path='/' element={<HomePage />} />
<Route exact path='/auth:p' element={<AuthPage />} />
<Route exact path='/search' element={<SearchPage />} />
<Route exact path='/search:id' element={<SectionPage />} />
<Route exact path='/mostra' element={<MostraPage />} />
<Route exact path='/prenota' element={<PrenotaPage/>} />
<Route exact path='/profile' element={<AccountPage />} />
<Route exact path='*' element={<span>Page not found</span>} />
</Routes>
</Suspense>
<Footer />
</div>
)
}
export default App
The index.js code:
import { createRoot } from 'react-dom/client'
import { Provider } from 'react-redux'
import store, { persistor } from './redux/store/store'
import App from './app/App'
import reportWebVitals from './reportWebVitals'
import { PersistGate } from 'redux-persist/integration/react'
import { BrowserRouter } from 'react-router-dom'
const container = document.getElementById('root')
const root = createRoot(container)
root.render(
<BrowserRouter>
<Provider store={store}>
<PersistGate persistor={persistor}>
<App />
</PersistGate>
</Provider>
</BrowserRouter>
)
reportWebVitals()
I thank in advance anyone who tries to help.
In the project, when rendering to another page I used the useNavigate hook and passed { replace: true } as the second parameter.
However, in this way the navigation will replace the current entry in the history stack instead of adding a new one by not then making the GoBack component work properly.
So it was enough to remove { replace: true } from the calls to useNavigate and now it works.

I have a problem with the router V6. The routes are not being rendered. The homepage use to have all the products and now I cannot see any of the products shown, also I have my code to the links that go to every part of the website but is not appearing. The error that appears is:
react_devtools_backend.js:4045 No routes matched location "/rewards-store-andrea-lopez-bravo"

In the menu.jsx the links are not rendering:
import "./Menu.css";
import React from "react";
import { Link } from "react-router-dom";
export const Menu =()=>{
return(
<ul className="menu flex-row">
<li className="pink-line"><Link className="normal-text" to="/acamica-rewards-store/">Home</Link></li>
<li className="pink-line"><Link className="normal-text" to="/acamica-rewards-store/points">Add points</Link></li>
<li className="pink-line"><Link className="normal-text" to="/acamica-rewards-store/history">History</Link></li>
</ul>
)
}
In your router always put the home route at the very bottom!
<Routes>
<Route path="/history" element={<History/>}/>
<Route path="points" element={<Points/>}/>
<Route path="NotFound" element={<NotFound/>} />
<Route path="/" element={<Home />} />
</Routes>
or make sure to make the home path as exact!
<Routes>
<Route exact path="/" element={<Home />} />
<Route path="/history" element={<History/>}/>
<Route path="points" element={<Points/>}/>
<Route path="NotFound" element={<NotFound/>} />
</Routes>
I did this in v.6
<Route path="/cart" element={<CartPage />}>
<Route path=":id" element={<CartPage />} />
</Route>
I am doing a personal React.js project. I am trying to use react-router-dom, but I haven't been able to make it work. I did the BrowserRouter in the App.js. Till there the app works fine, but I cannot make the routing redirect dynamically to a map item. I tried to follow the documentation and some tutorials unsuccesfully. The data comes from the Star Wars API This is the code:
App.js:
import './App.css';
import { Route, BrowserRouter as Router, Routes } from "react-router-dom";
import Home from './components/Home';
import MovieDetail from './components/MovieDetail'
import Navbar from './components/Navbar';
function App() {
return (
<Router>
<>
<Navbar />
<Routes>
<Route exact path='/' element={<Home />} />
</Routes>
<Routes>
<Route exact path to='/:movieId' element={<MovieDetail />} />
</Routes>
</>
</Router>
);
}
export default App;
ItemDetail:
import { useEffect, useState } from "react";
import { useParams } from "react-router-dom";
const MovieDetail = () => {
const { movieId } = useParams();
const [result, setResult] = useState([]);
const fetchData = async () => {
const res = await fetch("https://www.swapi.tech/api/films/");
const json = await res.json();
setResult(json.result);
}
useEffect(() => {
fetchData();
}, []);
let movieMatch = (result.find(value) => value.properties.title == movieId)
return (
<div>
<h2>
{result
.find((value) => {value.properties.title == movieId})}
</h2>
</div>
);
}
export default MovieDetail;
UPDATE
This is a link to the whole code in codesand with updated App.js
From your code I'm assuming you're using React Router v6 in your project. Try the below code:
import './App.css';
import { BrowserRouter, Routes, Route } from "react-router-dom";
import Home from './components/Home';
import MovieDetail from './components/MovieDetail'
import Navbar from './components/Navbar';
function App() {
return (
<BrowserRouter>
<Routes>
<Navbar />
<Route path='/' element={<Home />} />
<Route path=':movieId' element={<MovieDetail />} />
</Routes>
</BrowserRouter>
);
}
export default App;
Checkout React Router's Documentation for more detail.
if you are using index.js as a wrapper for app.js <BrowserRouter /> or <Router /> in your case is not used in app.js it's used in index.js otherwise it will not work
index.js should look like this : -
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
function App() {
return <h1>Hello React Router</h1>;
}
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById("root")
);
**For example just Let's say you are having "/movies" route and you want when ever your app (route = "/") starts / loads up to be redirected to "/movies" **
then wrap the routing logic with *<Switch />* ,make use of Redirect property of router dom to redirect from "/" to "/movies" and use component instead of element to render the corresponding component plus dont wrap with <Routes> </Routes> every time you are doing the route as we used it in index.js
then app.js will be : -
import './App.css';
import { Route, BrowserRouter as Router, Routes } from "react-router-dom";
import Home from './components/Home';
import MovieDetail from './components/MovieDetail'
import Navbar from './components/Navbar';
function App() {
return (
<>
<Navbar />
<Switch>
<Route exact path='/movies' component={<Home />} />
<Route exact path to='movies/:movieId' component={<MovieDetail />}
// to redirect from "/" to "/movies"
<Redirect from="/" to="/students"></Redirect>
);
}
If I am using react-query and react-router, I can see the network requests happening when navigating, however the new data is not reflected in the view/page? Am I doing something wrong? I am doing lazy loading:
App.tsx
import React, { Suspense } from 'react';
import Loader from '../loader/Loader';
const App: React.FunctionComponent = () => {
const Routing = React.lazy(() => import('../routing/Routing'));
return (
<>
<Suspense fallback={<Loader />}>
<DataProvider>
<Routing />
</DataProvider>
</Suspense>
</>
);
}
export default App;
router component:
import React from 'react';
import { BrowserRouter, Route, Switch} from 'react-router-dom';
import Header from '../header/Header';
import Component1 from './Component1';
import Compontent2 from './Component2';
import { QueryClient, QueryClientProvider } from 'react-query';
import { RouteComponentProps } from "react-router-dom";
const queryClient = new QueryClient()
const Routing: React.FunctionComponent = () => {
return (
<QueryClientProvider client={queryClient}>
<BrowserRouter>
<Header />
<div className="App">
<Switch>
<Route exact path="/" component={Component1} />
<Route path="/details/:id" render={(props: RouteComponentProps<any>) => <Component2 {...props}/>} />
</Switch>
</div>
</BrowserRouter>
</QueryClientProvider>
)
}
export default Routing;
Component 1
const fetchAll = async () => {
const res = await fetch('https:xxxxxx/xxxxx');
return res.json();
};
const { data: result, status } = useQuery('info', fetchAll, {
staleTime: 0,
});
component 2 is using the same approach the react-query stuff is not in useEffect of anything?
How can I get the view to re-render on navigation and show the new data.
try and move the call to React.lazy outside of the fallback component?
const Routing = React.lazy(() => import('../routing/Routing'));
const App: React.FunctionComponent = () => {
return (
<>
<Suspense fallback={<Loader />}>
<DataProvider>
<Routing />
</DataProvider>
</Suspense>
</>
);
}
export default App;
That's how they're using it in the official React docs here:
https://reactjs.org/docs/code-splitting.html
Protected Routes.js:
In protected routes you can see I'm using directly false in if statement but I'm still able to see that page why?
import React from 'react';
import { Route } from 'react-router-dom';
// import Auth from './User/Auth';
import Error401 from './Error/401';
// create a component for protected route
console.log('Routes.js');
export const ProtectedRoute = ({ element: Element, ...rest }) => {
console.log("Function Called")
return (
<Route {...rest} render={props => {
if(false){
return <Element {...props} />
}else{
return <Error401 />
}
}
} />
)
}
App.js:
This is app.js where I'm using protected routes component
import './App.css';
import React from 'react';
import { BrowserRouter, Route, Routes } from 'react-router-dom';
import { Layout } from 'antd';
import { MoneyCollectOutlined } from '#ant-design/icons';
import Login from './Components/User/Login';
import Signup from './Components/User/Signup';
import {ProtectedRoute} from './Components/Routes';
import Error404 from './Components/Error/404';
function App() {
return (
<BrowserRouter>
<Layout style={{minHeight:"100vh"}}>
<Layout.Header>
<h1 style={{color:"white"}} align="center"> <MoneyCollectOutlined/>MoneyG</h1>
</Layout.Header>
<Layout.Content style={{minHeight:"100%"}}>
<Routes>
<ProtectedRoute exact path="/register" element={<Signup/>} />
<ProtectedRoute exact path="/login" element={<Login/>} />
<Route path="*" element={<Error404/>} />
</Routes>
</Layout.Content>
</Layout>
</BrowserRouter>
);
}
export default App;
First, <Routes> elements should only have <Route> elements as children. You should move your protection logic down a layer.
Secondly, the render prop doesn't exist anymore in V6. It was replaced in favor of element. See doc.
Here is how you might tackle it:
<Routes>
<Route exact path="/register" element={(
<ProtectedRoute>
<Signup/>
</ProtectedRoute>
)} />
<Route exact path="/login" element={(
<ProtectedRoute>
<Login/>
</ProtectedRoute>
)} />
<Route path="*" element={<Error404/>} />
</Routes>
And:
const ProtectedRoute = () => {
if (condition) { return <Error401 />; } // You might as well use Navigate here
return children;
};
you can use createContext & useContext
//store/AuthApi.jsx
import { createContext } from "react";
const AuthApi = createContext();
export default AuthApi;
Then define the context app.jsx
import React, from 'react'
import { AllRoutes } from 'routes/Routes';
import { BrowserRouter as Router } from "react-router-dom";
import AuthApi from 'store/AuthApi';
const App = () => {
const [user, setUser] = useState(false);
useEffect(() => {
// you can get user from localStorage or Cookie(js-cookie npm)
//then you can change user state true or false
}, [])
return (
<>
<AuthApi.Provider value={{ user, setUser }}>
<Router>
<AllRoutes />
</Router>
</AuthApi.Provider>
<Toast />
</>
)
}
export default App
then see AllRoutes
//routes/Routes
import React, { useContext } from "react";
import { Routes, Route } from "react-router-dom";
import { SignIn, SignUp, Dashboard } from "pages";
import AuthApi from "store/AuthApi";
export const ProtectedRouting = () => {
return (
<Routes >
<Route path='/' exact element={<Dashboard />} />
// add more protected routes
</Routes>
)
}
export const AuthRouting = () => {
return (
<Routes >
<Route exact={true} path='/sign-in' element={<SignIn />} />
<Route exact={true} path='/sign-up' element={<SignUp />} />
</Routes>
)
}
export const AllRoutes = ()=> {
const context = useContext(AuthApi);
console.log(context.user)
return (
context.user ?
<ProtectedRouting />
: <AuthRouting />
)
}
pages/SignIn.jsx
import React,{ useContext } from 'react';
import AuthApi from "store/AuthApi";
const SignIn = () => {
const context = useContext(AuthApi);
const signInSubmit =(e)=> {
e.preventDefault();
//post request to signin
// if login is successfull then save user or token in cookie or localStorage or something
context?.setUser(true);
//...
}
return (
//signin code here
<form onSubmit={signInSubmit}>
///input here
</form>
)
}
export default SignIn
I have a component that is used persistently across my spa. I want it to be aware of my router and the various paths that my spa is on. Is there an easy way to do this, or do I have to bandaid some redux (or something similar) state solution that is always listening to my router changes? Thanks! You can see the below for an example.
index.jsx:
import 'babel-polyfill';
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'connected-react-router';
import { Route, Switch } from 'react-router-dom';
import { history, store } from './redux/store';
import Navigation from './navigation';
const UserReport = () => <h2>User Report</h2>;
const UserPage = () => <h2>User Page</h2>;
const Routes = () => (
<React.Fragment>
<Route component={Navigation} />
<Switch>
<Route exact path="/users/:startDate" component={UserReport} />
<Route exact path="/users/:userId" component={UserPage} />
</Switch>
</React.Fragment>
);
render(
<Provider store={store}>
<ConnectedRouter history={history}>
<Routes />
</ConnectedRouter>
</Provider>, document.getElementById('app'),
);
navigation.jsx:
import React from 'react';
import { withRouter } from 'react-router-dom';
const Navigation = (props) => {
console.log(props.match.path);
// expected: "/users/:startDate"
// received: "/"
return (
<h2>Navigation</h2>
);
};
export default withRouter(Navigation);
Since the Navigation route doesn't have any path specified, it always matches whatever path you're on but the match.path only shows you the minimum path required to match for the navigation. That's why it's always /.
You can use location.pathname but it gives you the matched value and not the matched path.
const Navigation = props => {
console.log(props.location.pathname);
// prints `/users/1` if you're on https://blah.com/users/1
// prints `/users/hey` if you're on https://blah.com/users/hey
return <h2>Navigation</h2>;
};
Not sure that's what you want but if you expand what exactly you're trying to achieve, maybe I can help more.
Moreover, your second route to path="/users/:userId" overshadows the first route. Meaning there is no way to tell if hey in /users/hey is startDate or userId. You should introduce a separate route like path="/users/page/:userId".
I ended up using this react-router github discussion as my solution.
An example of my implementation:
index.jsx:
import 'babel-polyfill';
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'connected-react-router';
import { Route, Switch } from 'react-router-dom';
import { history, store } from './redux/store';
import Layout from './layout';
const home = () => <h2>Home Page</h2>;
const users = () => <h2>Users</h2>;
const userPage = () => <h2>User Page</h2>;
const layoutRender = component => route => <Layout component={component} route={route} />;
const Routes = () => (
<Switch>
<Route exact path="/" component={layoutRender(home)} />
<Route exact path="/users" component={layoutRender(users)} />
<Route exact path="/users/:id" component={layoutRender(userPage)} />
</Switch>
);
render(
<Provider store={store}>
<ConnectedRouter history={history}>
<Routes />
</ConnectedRouter>
</Provider>, document.getElementById('app'),
);
layout.jsx:
import React from 'react';
const Layout = (props) => {
const {
component: Component,
route,
} = props;
return (
<div>
<h1>This is the layout</h1>
<Component route={route} />
</div>
);
};
export default Layout;
