localStorage retuning `undefined` on ReactJS and react-router-v4 code - javascript

I´m bulding a simple router to build my authentication mechanism. The mechanism will use JWT stored in localStorage to know I´m authenticated. Here is my code:
import React, { Component } from "react";
import PropTypes from "prop-types";
import {
BrowserRouter as Router,
Switch,
Route,
Redirect
}
const isAuthenticated = () => {
let token = localStorage.getItem("jwtToken");
console.log('Local Storage JWT TOKEN:');
console.log(token); // <<<<=== undefined
if (token) {
return true;
}
return false;
};
const AuthenticatedRoute = ({ component: Component, ...rest }) =>
<Route
{...rest}
render={props =>
isAuthenticated()
? <Component {...props} />
: <Redirect
to={{
pathname: "/landing",
state: { from: props.location }
}}
/>}
/>;
class App extends Component {
render() {
return (
<Router>
<Switch>
<Route exact path="/landing" component={Landing} />
<Route exact path="/logout" component={Logout} />
<Route exact path="/pagenotfound" component={PageNotFound} />
<AuthenticatedRoute exact path="/" component={AppNav} />
<AuthenticatedRoute
exact
path="/:option"
component={AppNav}
/>
<Route component={PageNotFound} />
</Switch>
</Router>
);
}
}
export default App;
For some reason localStorage.getItem is returnin undefined if no token is found. I was expecting null here as expected here
Why is my getItem returning undefined and how to solve it?

Error: [PrivateRoute] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>

I'm using React Router v6 and am creating private routes for my application.
In file PrivateRoute.js, I've the code
import React from 'react';
import {Route,Navigate} from "react-router-dom";
import {isauth} from 'auth'
function PrivateRoute({ element, path }) {
const authed = isauth() // isauth() returns true or false based on localStorage
const ele = authed === true ? element : <Navigate to="/Home" />;
return <Route path={path} element={ele} />;
}
export default PrivateRoute
And in file route.js I've written as:
...
<PrivateRoute exact path="/" element={<Dashboard/>}/>
<Route exact path="/home" element={<Home/>}/>
I've gone through the same example React-router Auth Example - StackBlitz, file App.tsx
Is there something I'm missing?
I ran into the same issue today and came up with the following solution based on this very helpful article by Andrew Luca
In PrivateRoute.js:
import React from 'react';
import { Navigate, Outlet } from 'react-router-dom';
const PrivateRoute = () => {
const auth = null; // determine if authorized, from context or however you're doing it
// If authorized, return an outlet that will render child elements
// If not, return element that will navigate to login page
return auth ? <Outlet /> : <Navigate to="/login" />;
}
In App.js (I've left in some other pages as examples):
import './App.css';
import React, {Fragment} from 'react';
import {BrowserRouter as Router, Route, Routes} from 'react-router-dom';
import Navbar from './components/layout/Navbar';
import Home from './components/pages/Home';
import Register from './components/auth/Register'
import Login from './components/auth/Login';
import PrivateRoute from './components/routing/PrivateRoute';
const App = () => {
return (
<Router>
<Fragment>
<Navbar/>
<Routes>
<Route exact path='/' element={<PrivateRoute/>}>
<Route exact path='/' element={<Home/>}/>
</Route>
<Route exact path='/register' element={<Register/>}/>
<Route exact path='/login' element={<Login/>}/>
</Routes>
</Fragment>
</Router>
);
}
In the above routing, this is the private route:
<Route exact path='/' element={<PrivateRoute/>}>
<Route exact path='/' element={<Home/>}/>
</Route>
If authorization is successful, the element will show. Otherwise, it will navigate to the login page.
Only Route components can be a child of Routes. If you follow the v6 docs then you'll see the authentication pattern is to use a wrapper component to handle the authentication check and redirect.
function RequireAuth({ children }: { children: JSX.Element }) {
let auth = useAuth();
let location = useLocation();
if (!auth.user) {
// Redirect them to the /login page, but save the current location they were
// trying to go to when they were redirected. This allows us to send them
// along to that page after they login, which is a nicer user experience
// than dropping them off on the home page.
return <Navigate to="/login" state={{ from: location }} />;
}
return children;
}
...
<Route
path="/protected"
element={
<RequireAuth>
<ProtectedPage />
</RequireAuth>
}
/>
The old v5 pattern of create custom Route components no longer works. An updated v6 pattern using your code/logic could look as follows:
const PrivateRoute = ({ children }) => {
const authed = isauth() // isauth() returns true or false based on localStorage
return authed ? children : <Navigate to="/Home" />;
}
And to use
<Route
path="/dashboard"
element={
<PrivateRoute>
<Dashboard />
</PrivateRoute>
}
/>
Complement to reduce lines of code, make it more readable and beautiful.
This could just be a comment but I don't have enough points, so I'll
put it as an answer.
Dallin's answer works but Drew's answer is better! And just to complete Drew's answer on aesthetics, I recommend creating a private component that takes components as props instead of children.
Very basic example of private routes file/component:
import { Navigate } from 'react-router-dom';
const Private = (Component) => {
const auth = false; //your logic
return auth ? <Component /> : <Navigate to="/login" />
}
Route file example:
<Routes>
<Route path="/home" element={<Home />} />
<Route path="/user" element={<Private Component={User} />} />
</Routes>
I know that this is not exactly the recipe on how to make PirvateRoute work, but I just wanted to mention that the new documentation recommends a slightly different approach to handle this pattern with react-router v6:
<Route path="/protected" element={<RequireAuth><ProtectedPage /></RequireAuth>} />
import { Navigate, useLocation } from "react-router";
export const RequireAuth: React.FC<{ children: JSX.Element }> = ({ children }) => {
let auth = useAuth();
let location = useLocation();
if (!auth.user) {
return <Navigate to="/login" state={{ from: location }} />;
}
return children;
};
And you are supposed to add more routes inside ProtectedPage itself if you need it.
See the documentation and an example for more details. Also, check this note by Michael Jackson that goes into some implementation details.
Just set your router component to element prop:
<Routes>
<Route exact path="/" element={<Home />} />
<Route path="/about" element={<About />} />
<Route path="/dashboard" element={<Dashboard />} />
</Routes>
You can also check for upgrading from v5.
Remove the PrivateRoute component from your project and use the following code in your App.js files:
import {Navigate} from "react-router-dom";
import {isauth} from 'auth'
...
<Route exact path="/home" element={<Home/>}/>
<Route exact path="/" element={isauth ? <Dashboard/> : <Navigate to="/Home" />}/>
It's 2022 and I did something like below:
// routes.tsx
import { lazy } from "react";
import { Routes, Route } from "react-router-dom";
import Private from "./Private";
import Public from "./Public";
const Home = lazy(() => import("../pages/Home/Home"));
const Signin = lazy(() => import("../pages/Signin/Signin"));
export const Router = () => {
return (
<Routes>
<Route path="/" element={Private(<Home />)} />
<Route path="/signin" element={Public(<Signin />)} />
</Routes>
);
};
// Private.tsx
import { Navigate } from "react-router-dom";
import { useEffect, useState } from "react";
function render(c: JSX.Element) {
return c;
}
const Private = (Component: JSX.Element) => {
const [hasSession, setHasSession] = useState<boolean>(false);
useEffect(() => {
(async function () {
const sessionStatus = await checkLoginSession();
setHasSession(Boolean(sessionStatus));
})();
}, [hasSession, Component]);
return hasSession ? render(Component) : <Navigate to="signin" />;
};
export default Private;
Hope this helps!
React Router v6, some syntactic sugar:
{auth && (
privateRoutes.map(route =>
<Route
path={route.path}
key={route.path}
element={auth.isAuthenticated ? <route.component /> : <Navigate to={ROUTE_WELCOME_PAGE} replace />}
/>
)
)}
I tried all answers, but it always displayed the error:
Error: [PrivateRoute] is not a component. All component children of must be a or <React.Fragment>
But I found a solution ))) -
In PrivateRoute.js file:
import React from "react"; import { Navigate } from "react-router-dom";
import {isauth} from 'auth'
const PrivateRoute = ({ children }) => {
const authed = isauth()
return authed ? children : <Navigate to={"/Home" /> };
export default ProtectedRoute;
In the route.js file:
<Route
path="/"
element={
<ProtectedRoute >
<Dashboard/>
</ProtectedRoute>
}
/>
<Route exact path="/home" element={<Home/>}/>
Children of Routes need to be Route elements, so we can change the ProtectedRoute:
export type ProtectedRouteProps = {
isAuth: boolean;
authPath: string;
outlet: JSX.Element;
};
export default function ProtectedRoute({
isAuth,
authPath,
outlet,
}: ProtectedRouteProps) {
if (isAuth) {
return outlet;
} else {
return <Navigate to={{pathname: authPath}} />;
}
}
And then use it like this:
const defaultProps: Omit<ProtectedRouteProps, 'outlet'> = {
isAuth: //check if user is authenticated,
authPath: '/login',
};
return (
<div>
<Routes>
<Route path="/" element={<ProtectedRoute {...defaultProps} outlet={<HomePage />} />} />
</Routes>
</div>
);
This is the simple way to create a private route:
import React from 'react'
import { Navigate } from 'react-router-dom'
import { useAuth } from '../../context/AuthContext'
export default function PrivateRoute({ children }) {
const { currentUser } = useAuth()
if (!currentUser) {
return <Navigate to='/login' />
}
return children;
}
Now if we want to add a private route to the Dashboard component we can apply this private route as below:
<Routes>
<Route exact path="/" element={<PrivateRoute><Dashboard /></PrivateRoute>} />
</Routes>
For longer elements
<Router>
<div>
<Navbar totalItems={cart.total_items}/>
<Routes>
<Route exact path='/'>
<Route exact path='/' element={<Products products={products} onAddToCart={handleAddToCart}/>}/>
</Route>
<Route exact path='/cart'>
<Route exact path='/cart' element={<Cart cart={cart}/>}/>
</Route>
</Routes>
</div>
</Router>
Header will stay on all page
import React from 'react';
import {
BrowserRouter,
Routes,
Route
} from "react-router-dom";
const Header = () => <h2>Header</h2>
const Dashboard = () => <h2>Dashboard</h2>
const SurveyNew = () => <h2>SurveyNew</h2>
const Landing = () => <h2>Landing</h2>
const App = () =>{
return (
<div>
<BrowserRouter>
<Header />
<Routes >
<Route exact path="/" element={<Landing />} />
<Route path="/surveys" element={<Dashboard />} />
<Route path="/surveys/new" element={<SurveyNew/>} />
</Routes>
</BrowserRouter>
</div>
);
};
export default App;
<Route path='/' element={<Navigate to="/search" />} />
You can use a function for a private route:
<Route exact path="/login" element={NotAuth(Login)} />
<Route exact path="/Register" element={NotAuth(Register)} />
function NotAuth(Component) {
if (isAuth)
return <Navigate to="/" />;
return <Component />;
}
I'm using "react-router-dom": "^6.3.0" and this is how I did mine
PrivateRoute Component and Route
import {Route} from "react-router-dom";
const PrivateRoute = ({ component: Compontent, authenticated }) => {
return authenticated ? <Compontent /> : <Navigate to="/" />;
}
<Route
path="/user/profile"
element={<PrivateRoute authenticated={true} component={Profile} />} />
For the error "[Navigate] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>", use the following method maybe solved:
DefaultPage is when no match router. Jump to the DefaultPage. Here use the <Route index element={} /> to replace the
<Navigate to={window.location.pathname + '/kanban'}/>
See Index Routes
<Routes>
<Route path={'/default'} element={<DefaultPage/>}/>
<Route path={'/second'} element={<SecondPage/>}/>
{/* <Navigate to={window.location.pathname + '/kanban'}/> */}
<Route index element={<DefaultPage/>} />
</Routes>
import { BrowserRouter as Router, Routes, Route, Link } from "react-router-dom";
function App() {
return (
<Router>
<Routes>
<Route path="/" element={<h1>home page</h1>} />
<Route path="/seacrch" element={<h1>seacrch page</h1>} />
</Routes>
</Router>
);
}
export default App;

Always redirected to current route instead of desired route

I am using ternary operator to render component using react route. But I am always redirected to "/" route instead of desired component even if the condition is as expected.
I get desired functionality only when I refresh/reload the page.
This is my App.js with all the routes
import React, { useEffect, useState } from 'react';
import Header from './Components/Header';
import Home from './Components/Home';
import Checkout from "./Components/Checkout";
import Payment from "./Components/Payment";
import NewProduct from "./Components/NewProduct";
import OrderSuccess from "./Components/OrderSuccess";
import AddressForm from './Components/AddressForm';
import {BrowserRouter, Switch, Route} from "react-router-dom";
import { Redirect } from 'react-router';
import Login from './Components/Login';
import Orders from "./Components/Orders";
import Account from './Components/Account';
import { connect } from 'react-redux';
const App=()=>{
const user = (JSON.parse(localStorage.getItem("profile")));
const defaultRoutes= ()=>{
return(
<div>
<Header/>
<Switch>
<Route path="/account-settings" exact component={()=>user ? <Account />: <Redirect to="/" />} />
<Route path="/orders" exact component={()=>user ? <Orders /> : <Redirect to="/" />} />
<Route path="/checkout" exact component={()=>user ? <Checkout />: <Redirect to="/" />} />
<Route path="/payment" exact component={()=>user ? <Payment /> : <Redirect to="/" />} />
<Route path="/account-settings/add-new-address" exact component={()=>user?.result ? <AddressForm /> : <Redirect to="/" />} />
<Route path="/" exact component={Home} />
</Switch>
</div>
)
}
return (
<BrowserRouter>
<Switch>
<Route path="/login" exact component={()=>user ? <Redirect to="/" />:<Login />} />
<Route component={defaultRoutes} />
</Switch>
</BrowserRouter>
);
}
export default App;
This is my index.js file
import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import { Provider } from "react-redux";
import { createStore, applyMiddleware, compose } from "redux";
import thunk from "redux-thunk";
import "./index.css"
import reducers from "./reducers/index";
const store = createStore(reducers,{},compose(applyMiddleware(thunk)));
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>
, document.getElementById("root")
)
This is reducer where I am updating my localstorage
export default (state={authData:null},action)=>{
switch(action.type){
case "AUTH":
localStorage.setItem("profile",JSON.stringify({...action?.data}));
return {...state, authData: action.data, loading: false, errors: null};
case "LOGOUT":
localStorage.clear();
return {...state,authData:null};
default:
return "";
}
}
Remove the ternary in the router. Use useHistory to redirect to "/" if the condition is not met.
For checking the condition, create a custom hook called useCheckUser which checks if there is a user in the localStorage.
In every component where user is required,
import useCheckUser from "file-address"
import { useHistory } from "react-router"
const Component = () => {
let history = useHistory();
let user = useCheckUser();
if (!user) {
history.push("/");
}
return ()
}
The useCheckUser hook should be something similar to
const useCheckUser = () => {
let user = localStorage.getItem("profile");
if (user) {
return JSON.parse(user);
}
return null;
};
export default useCheckUser;
NOTE: If your only requirement is rendering components when the user is present, you can change your custom hook so that it does everything including the redirecting. This is just to return the current user. So this can be used if you want to render certain components like auth pages if and only if the user is not present.
try to take the user a State (useState), and set it in the useEffect like this:
const [user, setUser] = useState(null);
useEffect(() => {
setUser(localStorage.getItem("profile"))
}, [])
it will set the "user" as your page rendered
function App() {
const [user, setUser] = useState(null);
useEffect(() => {
setUser(localStorage.getItem("profile"))
}, [])
const authentication = {
getLogInStatus() {
return user;
},
};
}
function SecuredRoute(props) {
return (
<Route
path={props.path}
render={(data) =>
authentication.getLogInStatus() ? (
<props.component
{...data}
></props.component>
) : (
handleRedirect()
)
}
></Route>
);
}
const handleRedirect = () => {
let login = window.confirm(
"please Register or log in to access this page!"
);
if (login) {
return <Redirect path="/"></Redirect>;
}
};
return (
<BrowserRouter>
<Switch>
// those routes which don't needs authetication
<Route path="/home" compponent={Home} />
<Route path="/login" compponent={Login} />
//and others
// those routes which needs authetication
<SecuredRoute path="/bookings" component={Bookings} />
<SecuredRoute
path="/booking-details"
component={BookingDetails}
/>
<SecuredRoute path="/favorites" component={Favorites} />
<SecuredRoute path="/profile" component={Profile} />
</Switch>
</BrowserRouter>
);
}
Issue
You are close. The issue here is that even though you store the auth in localStorage and update the redux state, App isn't being rerendered to "pick up" the new auth value from localStorage.
Solution
Initialize the redux state from localStorage.
Select the authentication state from your Redux store. This is so changes to the store trigger subscribed components to rerender.
Auth Reducer
const initialState={
authData:JSON.parse(localStorage.getItem("profile")),
loading:false,
errors:null
};
export default (state = initialState, action) => {
switch(action.type){
case "AUTH":
localStorage.setItem("profile", JSON.stringify({ ...action?.data }));
return {
...state,
authData: action?.data,
loading: false,
errors: null
};
case "LOGOUT":
localStorage.clear();
return { ...state, authData: null };
default:
return state;
}
};
App
import { useSelector } from "react-redux";
const App = () => {
const user = useSelector(state => state.auth.authData);
const defaultRoutes = () => {
return (
<div>
<Header/>
<Switch>
<Route
path="/account-settings"
render={() => user ? <Account />: <Redirect to="/" />}
/>
<Route
path="/orders"
render={() => user ? <Orders /> : <Redirect to="/" />}
/>
<Route
path="/checkout"
render={() => user ? <Checkout />: <Redirect to="/" />}
/>
<Route
path="/payment"
render={() => user ? <Payment /> : <Redirect to="/" />}
/>
<Route
path="/account-settings/add-new-address"
render={() => user?.result ? <AddressForm /> : <Redirect to="/" />}
/>
<Route path="/" component={Home} />
</Switch>
</div>
)
};
return (
<BrowserRouter>
...
</BrowserRouter>
);
}
Suggestion
Review the auth workflow and create a PrivateRoute component that handles the redirect for you.
Example:
const PrivateRoute = props => {
const user = useSelector(state => state.auth.authData);
return user ? <Route {...props} /> : <Redirect to="/" />
};
Usage:
const App = () => {
const defaultRoutes = () => {
return (
<div>
<Header/>
<Switch>
<PrivateRoute path="/account-settings" component={Account} />
<PrivateRoute path="/orders" component={Orders} />
<PrivateRoute path="/checkout" component={Checkout} />
<PrivateRoute path="/payment" component={Payment} />
<Route
path="/account-settings/add-new-address"
render={() => user?.result ? <AddressForm /> : <Redirect to="/" />}
/>
<Route path="/" component={Home} />
</Switch>
</div>
)
};
return (
<BrowserRouter>
...
</BrowserRouter>
);
}

React conditional rendering not triggering?

I am trying to change the contents of my Navbar and my Router via useContext and conditional rendering.
This is my App.js:
import "./App.css";
import axios from "axios";
import { AuthContextProvider } from "./context/AuthContext";
import MyRouter from "./MyRouter";
axios.defaults.withCredentials = true;
function App() {
return (
<AuthContextProvider>
<MyRouter />
</AuthContextProvider>
);
}
export default App;
This is my Router:
import React, { useContext } from "react";
import AuthContext from "./context/AuthContext";
import {
BrowserRouter as Router,
Switch,
Route,
Redirect,
} from "react-router-dom";
import MyNavBar from "./components/MyNavbar";
import "./App.css";
import Home from "./components/pages/Home";
import AboutUs from "./components/pages/AboutUs";
import Register from "./components/pages/Register";
import MyFooter from "./components/MyFooter";
import login from "./components/pages/login";
import ProfilePage from "./components/pages/ProfilePage";
function MyRouter() {
const { loggedIn } = useContext(AuthContext);
return (
<Router>
<MyNavBar />
<Switch>
<Route exact path="/" component={Home} />
<Route exact path="/about-us" component={AboutUs} />
{loggedIn === false && (
<>
<Route exact path="/register" component={Register} />
<Route exact path="/login" component={login} />
</>
)}
{loggedIn === true && (
<>
<Route exact path="/profile" component={ProfilePage} />
</>
)}
<Redirect to="404" />
</Switch>
<MyFooter />
</Router>
);
}
export default MyRouter;
My Navbar's conditional rendering works in the same way as the router. My problem is that neither of the conditional rendering fragments are working. For example, when my application starts, users are not logged in and the "loggedIn" value is false. With this logic, the routes "register" and "login" should be accessible, but they are not. Any advice or help would be greatly appreciated as I am quite new to using React.
Here is a screenshot of my console upon loading the application
This is my "AuthContext":
const AuthContext = createContext();
function AuthContextProvider(props) {
const [loggedIn, setLoggedIn] = useState(undefined);
async function getLoggedIn() {
const loggedInRes = await axios.get(
"http://localhost:5000/api/users/loggedIn"
);
setLoggedIn(loggedInRes.data);
}
useEffect(() => {
getLoggedIn();
}, []);
return (
<AuthContext.Provider value={{ loggedIn, getLoggedIn }}>
{props.children}
</AuthContext.Provider>
);
}
export default AuthContext;
export { AuthContextProvider };
Thanks for all the help guys, I learned a lot about the ProtectedRoute concept. My issue came from my Navigation Bar component. Instead of declaring my variable as an object, I declared loggedin like
const loggedIn = useContext(AuthContext);
All my errors were solved once I changed it to
const { loggedIn } = useContext(AuthContext);
Edited:
Instead of using your conditions in your main route, you can create a ProtectedRoute which Routes your component according to your condition.
import React, { useEffect } from "react";
import { Route, Redirect, useHistory } from "react-router-dom";
const ProtectedRoute = ({ component: Component, ...rest }) => {
const { loggedIn } = useContext(AuthContext);
return (
<Route
{...rest}
render={(props) =>
loggedIn() ? (
<Component {...props} />
) : (
<Redirect to='/login' />
)
}
/>
);
};
export default ProtectedRoute;
In your component you can change your logic with this:
<ProtectedRoute exact path="/" component={Home} />
<ProtectedRoute exact path="/about-us" component={AboutUs}/>
<Route exact path="/register" component={Register} />
<Route exact path="/login" component={login} />
<ProtectedRoute exact path="/profile" component={ProfilePage} />
This means that if you wanna protect a route you should route it with ProtectedRoute otherwise classic react route.
You can read about that ProtectedRoute concept here

Authentication for a reactjs application using two private routes

My reactjs application has two types of Users namely Artist and Lovers. Some of my components are only accessible to artist and some are only accessible to lovers. So i need to implement Artist and User Routes that will help grand access only to the required User type.
And here is my Router Switch
<Switch>
<Route exact path='/' component={Home} />
<UserRoute authed={this.state.lover} path='/user-dash' component={About} />
<ArtistRoute authed={this.state.artist} path='/artist-dash' component={Contact} />
<Route path='/SignupUser' component={SignupUser} />
</Switch>
Here is my UserRoute code
import React from 'react';
import { Route, Redirect } from 'react-router-dom';
export const UserRoute = ({ component: Component, authed, ...rest }) => (
<Route {...rest} render={props => (
authed
? <Component {...props} />
: <Redirect to={{ pathname: '/', state: { from: props.location } }} />
)} />
)
I want to be able to receive the value of authed in the UserRoute passed in the switch. I do not know why authed in the UserRoute always returns false.
even when this.state.lover passed to it is true. Please what am I doing wrong.
Thanks
Route.jsx
<Switch>
<Route exact path='/' component={Home} />
<Route path='/user-dash' component={AuthCheck(About)} /> // Wrap the component with HOC
</Switch>
AuthCheck.jsx
export default function(Component) {
class AuthCheck extends Component {
render() {
if (this.props.auth.payload) {
return <Component {...this.props} /> // Component if auth is true
} else {
return <Route path='*' exact={true} component={NotFound} /> // 404 if not auth
}
}
}
function mapStateToProps(state) {
return { auth: state.auth }
}
return connect(mapStateToProps)(AuthCheck)
}
Check the above example works with redux
Make sure to import AuthCheck in the Route.jsx file

React Router Redirect drops param

I am using the next version of React Router, and it seems to be dropping params. I expect the redirect below to retain the value of channelId, but the to route uses the literal string ":channelId" in the path instead.
<Switch>
<Route exact path="/" component={Landing} />
<Route path="/channels/:channelId/modes/:modeId" component={Window} />
<Redirect
from="/channels/:channelId"
to="/channels/:channelId/modes/window" />
</Switch>
This looks like a resolved issue, but it's not working. Is there something else I need to pass to the to route?
Here's what I've been using, similar to the other answer but without a dependency:
<Route
exact
path="/:id"
render={props => (
<Redirect to={`foo/${props.match.params.id}/bar`} />;
)}
/>
I found no such logic in React Router 4 sources, so write own workaround:
import React, { Component } from 'react';
import PropTypes from 'prop-types';
import pathToRegexp from 'path-to-regexp';
import { Route, Redirect } from 'react-router-dom';
class RedirectWithParams extends Component {
render() {
const { exact, from } = this.props;
return (
<Route
exact={exact}
path={from}
component={this.getRedirectComponent}
/>);
}
getRedirectComponent = ({ match: { params } }) => {
const { push, to } = this.props;
const pathTo = pathToRegexp.compile(to);
return <Redirect to={pathTo(params)} push={push} />
}
};
RedirectWithParams.propTypes = {
exact: PropTypes.bool,
from: PropTypes.string,
to: PropTypes.string.isRequired,
push: PropTypes.bool
};
export default RedirectWithParams;
usage example:
<Switch>
<RedirectWithParams
exact from={'/resuorce/:id/section'}
to={'/otherResuorce/:id/section'}
/>
</Switch>
You can do this:
<Switch>
<Route exact path="/" component={Landing} />
<Route path="/channels/:channelId/modes/:modeId" component={Window} />
<Route
exact
path="/channels/:channelId"
render={({ match }) => (
<Redirect to={`/channels/${match.params.channelId}/modes/window`} />
)}
/>
</Switch>
I did this, and it worked:
<switch>
<Route path={`/anypath/:id`} component={Anycomponent} />
<Route
exact
path="/requestedpath/:id"
render={({ match }) => {
if (!Auth.loggedIn()) {
return <Redirect to={`/signin`} />;
} else {
return <Redirect to={`/anypath/${match.params.id}`} />;
}
}}
/>
</switch>
This functionality has been added to React Router 4 as of 4.3.0. If you're locked into a version before 4.3.x, Gleb's answer is the way to go.
You can do it using generatePath:
import { Switch, Route, Redirect, generatePath } from "react-router";
<Switch>
<Route component={PageOne} path="/one" />
<Route component={PageTwo} path="/two/:id" />
<Route
path="/three/:id"
render={props => (
<Redirect
to={generatePath("/two/:id", {
id: props.match.params.id,
})}
/>
)}
/>
<Route component={NotFoundPage} path="*" />
</Switch>
Short general version using generatePath that worked for me (redirecting from from path to to path, both having the same parameters):
import { Route, Redirect, generatePath } from "react-router"
<Route path={from}
exact
component={({match}) =>
<Redirect to={generatePath(to, match.params)} />} />
In React Router v6+ you could create your own NavigateWithParams like so
import { Navigate, NavigateProps, generatePath, useParams } from 'react-router-dom';
interface Props extends NavigateProps {
to: string;
}
const NavigateWithParams: React.FC<Props> = ({ to, ...props }) => {
const params = useParams();
return <Navigate {...props} to={generatePath(to, params)} />;
};
export default NavigateWithParams;
and use it like so:
<Route path="/old/:param" element={<NavigateWithParams to="/new/:param" />} />
