React error: No routes matched location "/" - javascript

My React app is giving me the error No routes matched location "/"
My App.js looks like:
import Form from './components/Form';
import NavMenu from './components/NavMenu';
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';
function App() {
// Irrelevant code
return (
<Router>
<div>
<NavMenu />
<Routes>
<Route path="/:nav_string" element={<Form />}></Route>
</Routes>
</div>
</Router>
);
}
export default App;
Any thoughts why this is happening?
I got rid of the error, although it's not a clean solution. I created a new component Home.js, added it to App.js with a route of "/" :
return (
<Router>
<div className="content">
<NavMenu response={response}/>
<Routes>
<Route path="/" element={<Home />}></Route> // Added home element
<Route path="/:nav_string" element={<Form response={response} />}></Route>
</Routes>
</div>
</Router>
);
Although I'm not a big fan of this solution because Home.js returns null. I just created it to get rid of this warning. What can someone do if they don't actually need a route with a path matching / ?

If you don't really need to render anything on the "/" path you could render a redirect to the form's route, perhaps with some default value.
Example:
return (
<Router>
<div className="content">
<NavMenu response={response} />
<Routes>
<Route path="/" element={<Navigate to="/someDefaultValue" replace />} />
<Route path="/:nav_string" element={<Form response={response} />} />
</Routes>
</div>
</Router>
);
An alternative could also be to render the Form component on both routes. RRD is optimized such that the Form component remains mounted while navigating between the routes or while the nav_string param value changes.
Example:
return (
<Router>
<div className="content">
<NavMenu response={response} />
<Routes>
<Route path="/" element={<Form response={response} />} />
<Route path="/:nav_string" element={<Form response={response} />} />
</Routes>
</div>
</Router>
);
Just make sure that Form can handle a potentially undefined nav_string param value. You could provide a fallback value.
const { nav_string = "someDefaultValue" } = useParams();
And then there is always the "catch all" route where you can render some fallback UI for any "unhandled" routes. This would include "/".
Example:
return (
<Router>
<div className="content">
<NavMenu response={response} />
<Routes>
<Route path="*" element={<NotFound />} />
<Route path="/:nav_string" element={<Form response={response} />} />
</Routes>
</div>
</Router>
);

You can add 404 route
Page not found will be displayed when no route matches the url
return (
<Router>
<div className="content">
<NavMenu response={response}/>
<Routes>
<Route path="/:nav_string" element={<Form response={response} />}></Route>
<Route path='*' element={<NotFound />} /> {/* You can change NotFound element*/}
</Routes>
</div>
</Router>
);

This should help:
<BrowserRouter>
<NavMenu/>
<Routes>
<Route path="/" element={<Form/>}></Route>
<Routes/>
<BrowserRouter/>

the format for "/:nav_string" is a path parameter, there is no "/" path
try type in for example "/Product", then it solved

How to create a 404 page with dynamic routes in React? [duplicate]

function App() {
return (
<RecoilRoot>
<Router>
<Navbar />
<Routes>
<Route path={"/"} element={<Home />} />
<Route path={`/page/:menu`} element={<MovieMenu />} />
<Route path={`/movie/:id`} element={<Detail />} />
<Route path={`/search/:searchText`} element={<Search />} />
<Route path={"*"} element={<NotFound />} />
</Routes>
</Router>
</RecoilRoot>
);
}
If i process 404 page in the above way, / handle it well, but <NotFound /> not be rendered if any path is entered after /page/fldlfsd;lf; or /search/dsklfskldf. Is there a way?
Paths like "/page/fldlfsd;lf;" and "/search/dsklfskldf" will be matched and rendered by the Routes component. The route param validation needs to occur in the routed component.
Each component can use the useParams hook to access the route param, validate it, and redirect to the NotFound route if param is invalid.
To help with this I suggest creating a discrete route to render NotFound so you can imperatively redirect to it from components and create a redirect route to handle unknown routes.
Example:
function App() {
return (
<RecoilRoot>
<Router>
<Navbar />
<Routes>
<Route path="/" element={<Home />} />
<Route path="/page/:menu" element={<MovieMenu />} />
<Route path="/movie/:id" element={<Detail />} />
<Route path="/search/:searchText" element={<Search />} />
<Route path="/404" element={<NotFound />} />
<Route path="*" element={<Navigate to="/404" replace />} />
</Routes>
</Router>
</RecoilRoot>
);
}
...
MovieMenu
const navigate = useNavigate();
const { menu } = useParams();
useEffect(() => {
... logic to validate menu param ...
if (invalidMenu) {
navigate("/404", { replace: true });
}
}, [menu, navigate]);

React router hashhistory moving basename property before the hash [duplicate]

i want to use that Hashrouter, but when i try, i got this error:
<Router basename="/admin"> is not able to match the URL "/" because it does not start with the basename, so the <Router> won't render anything.
i put "Homepage": "./admin" in packedjson
but when i use BrowserRouter, its render normaly, can anyone explain why, please?
The code i'm using to try to understand router v6:
import "./styles.css";
import {
BrowserRouter,
Routes,
Route,
Navigate,
Outlet,
Link,
HashRouter,
} from "react-router-dom";
const ProtectedRoutes = () => <Outlet />;
const Configuration = () => <h1>Configuration</h1>;
const SummaryPage = () => <h1>SummaryPage</h1>;
const Dashboard = () => <h1>Dashboard</h1>;
const Appointments = () => <h1>Appointments</h1>;
const NotFound = () => <h1>NotFound</h1>;
export default function App() {
return (
<HashRouter basename="/admin">
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<Link to="/dashboard" className="link">
Home
</Link>
</div>
<Routes>
<Route path="/configuration/configure" element={<Configuration />} />
<Route path="/configuration" element={<SummaryPage />} />
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/appointments" element={<Appointments />} />
<Route path="/" element={<Navigate replace to="/configuration" />} />
<Route path="*" element={<NotFound />} />
</Routes>
</HashRouter>
);
}
There mostly seems to be a misunderstanding with how the basename prop is applied in the router, specifically the HashRouter. With the HashRouter the basename prop is a value that is applied against the paths the app is handling, not against the domain path where the app is served/running.
Example:
<HashRouter basename="/admin">
<Link to="/dashboard" className="link"> // renders <a href="#/admin/dashboard">
Dashboard
</Link>
...
<Routes>
<Route path="/configuration">
<Route path="configure" element={<Configuration />} />
<Route index element={<SummaryPage />} />
</Route>
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/appointments" element={<Appointments />} />
<Route path="/" element={<Navigate replace to="/configuration" />} />
<Route path="*" element={<NotFound />} />
</Routes>
</HashRouter>
In other words, the basename prop value is applied to the URL hash and not the URL path, i.e. it's applied to everything after the hash.
mysite.com/someSubdomain/#/admin /something / ... more nested paths
|--domain-|--subdomain--|#|--------------hash-----------------|
| | | |basename| app path | ... app subpaths
If you are wanting the "/admin" to show up prior to the hash, then this is part of where the entire app is deployed to and served up from. In this case the app needs to be deployed to mysite.com in a "/admin" subdirectory. You also won't need to specify the basename="/admin" if you don't want an additional "/admin" to show up in the app's routing.
mysite.com/admin/#/something
...
<HashRouter>
<Link to="/dashboard" className="link"> // renders <a href="#/dashboard">
Dashboard
</Link>
...
<Routes>
<Route path="/configuration">
<Route path="configure" element={<Configuration />} />
<Route index element={<SummaryPage />} />
</Route>
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/appointments" element={<Appointments />} />
<Route path="/" element={<Navigate replace to="/configuration" />} />
<Route path="*" element={<NotFound />} />
</Routes>
</HashRouter>
update: Not a solution =[ basename not works in Routes, and hashrouter not working with basename
Some solution here:
https://github.com/remix-run/react-router/issues/7128#issuecomment-582591472
but i don't know if it's the best one.
// url where new router is created: https://my-site/who/users
const RootModule = () => {
return (
<main>
<BrowserRouter>
<Routes basename="who/users">
<nav>
<Link to="">Home</Link>
<Link to="who/users/about">About</Link>
<Link to="who/users/users">Users</Link>
</nav>
<Routes>
<Route path="/" element={<Home />} />
<Route path="who/users/about" element={<About />} />
<Route path="who/users/users" element={<Users />} />
</Routes>
</Routes>
</BrowserRouter>
</main>
);
};

react-router-dom v6 rendering new page over current page

the problem is the following. in the app.js is spelled out Routes and the home component. the home contains a navbar that navigates the site, only if you go to any page, it is drawn on top of the home. And if you switch to the home itself, it will be duplicated. Articles on the internet did not help, as did the addition of exact in route path.
function App() {
return (
<div className="messenger">
<Routes>
<Route path="/home/" element={<Home/>}/>
<Route path="/settings/" element={<Settings/>}/>
<Route path="/login/" element={<Login/>}/>
<Route path="/register/" element={<Register/>}/>
</Routes>
<Home/>
</div>
)
home
export default class Home extends Component {
render() {
return (
<div>
<NavBar/>
<ChatMenu/>
</div>
);
}
}
an example of how it is written in the navbar
export const NavBar = () => {
return (<div className="navbar-cm">
<div className="nav_element">
<Link to="/home">
<img src={homeIMG} className="nav_element"/>
</Link>
</div>
and a few more similar ones
</div>);
};
Issue
You are rendering the Home component again once outside the routes, this is why it's rendered with all routes including twice when on the "/home" path that renders Home.
function App() {
return (
<div className="messenger">
<Routes>
<Route path="/home/" element={<Home />} />
<Route path="/settings/" element={<Settings />} />
<Route path="/login/" element={<Login />} />
<Route path="/register/" element={<Register />} />
</Routes>
<Home /> // <-- always rendered below routed content
</div>
)
}
Solution
Remove the Home component that is out on its own outside the routes.
function App() {
return (
<div className="messenger">
<Routes>
<Route path="/home/" element={<Home />} /> // <-- now only Home component rendered
<Route path="/settings/" element={<Settings />} />
<Route path="/login/" element={<Login />} />
<Route path="/register/" element={<Register />} />
</Routes>
</div>
)
}
Remove <Home /> from the router:
function App() {
return (
<div className="messenger">
<Routes>
<Route path="/home/" element={<Home/>}/>
<Route path="/settings/" element={<Settings/>}/>
<Route path="/login/" element={<Login/>}/>
<Route path="/register/" element={<Register/>}/>
</Routes>
</div>
)

How to 1). put a div , 2). render a component without Route inside <Routes> with React Router in v6 React?

I want to put a div inside <Routes> and also Render a <Topbar /> and <Sidebar /> component inside <Routes> without <Route> tag for them.
My code is as follows:-
const App = () => {
return (
<Router>
<Routes>
<Route path="login" element={<Login />} />
<Topbar />
<div className="container">
<Sidebar />
<Route path="/" element={<Home />} />
<Route path="users" element={<UserList />} />
</div>
</Routes>
</Router>
);
};
I want to implement <Topbar /> and <Sidebar /> for all the routes.
But for an exception of login Page (Topbar and Sidebar should not be shown on the login page).
That's why I had put login Route at the top of Topbar and Sidebar.
The console is showing error as:
Uncaught Error: [Topbar] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>
How to implement this functionality?
In react-router-dom v6 only Route and React.Fragment components are valid children for the Routes component.
Use layout components to render the Topbar and Sidebar components along with an Outlet for nested routes for the routes you want to render these components.
Example:
import { Routes, Route, Outlet } from 'react-router-dom';
const Layout = () => (
<>
<Topbar />
<div className="container">
<Sidebar />
<Outlet />
</div>
</>
);
const App = () => {
return (
<Router>
<Routes>
<Route path="/login" element={<Login />} />
<Route element={<Layout />}>
<Route path="/" element={<Home />} />
<Route path="users" element={<UserList />} />
</Route>
</Routes>
</Router>
);
};
Change your routes like below,
you need to check whether user is logged in or not, if user logged in use Tobbar, Sidebar etc, otherwise just return login route
const App = () => {
const [isLogin, setIsLogin] = useState(false)
return (
<Router>
<Routes>
{ isLogin ? <Topbar />
<div className="container">
<Sidebar />
<Route path="/" element={<Home />} />
<Route path="users" element={<UserList />} />
</div> : <Route path="login" element={<Login />} />
</Routes>
</Router>
);
};
