Why i have an error when rendering components outside router? [duplicate] - reactjs

Question

I have a navbar that is rendered in every route while the route changes on click.
./components/navbar.jsx
import React, { Component } from 'react';
import '../App.css';
import { Link } from 'react-router-dom';
class Navbar extends Component {
constructor(props) {
super(props);
this.state = {};
}
render() {
return (
<div id = 'navbar'>
<div className='name-head'>
My Name
</div>
<div id = 'nav-links-container'>
<Link to='/experiences'>
<div className = 'nav-links'>
Experiences
</div>
</Link>
<div className = 'nav-links'>
Projects
</div>
<div className = 'nav-links'>
Skills
</div>
<div className = 'nav-links'>
Resume
</div>
</div>
</div>
);
}
}
export default Navbar;
./components/experiences.jsx
import React, { Component } from 'react';
class Experiences extends Component {
render() {
return (
<div>
<h1>hi</h1>
</div>
);
}
}
export default Experiences;
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import reportWebVitals from './reportWebVitals';
import Navbar from './components/Navbar';
import Home from './components/Home';
import Experiences from './components/experience';
import {
BrowserRouter as Router,
Routes,
Route
} from 'react-router-dom';
ReactDOM.render(
<React.StrictMode>
<Navbar />
<Router>
<Routes>
<Route path="/" element={<Home />} />
<Route path="/experiences" element={<Experiences />} />
</Routes>
</Router>
</React.StrictMode>,
document.getElementById('root')
);
reportWebVitals();
The error doesn't come when I remove the <Link> from the experiences tag in navbar.
There is a similar question posted here: Error: useHref() may be used only in the context of a <Router> component
but doesn't help.
I'm using react router v6

Answer 1

Issue
You are rendering the navbar outside the routing context. The Router isn't aware of what routes the links are attempting to link to that it is managing. The reason routing works when directly navigating to "/experiences" is because the Router is aware of the URL when the app mounts.
<Navbar /> // <-- outside router!!
<Router>
<Routes>
<Route path="/" element={<Home />} />
<Route path="/experiences" element={<Experiences />} />
</Routes>
</Router>
Solution
Move it inside the routing context so the Router is aware and can manage routing correctly.
<Router>
<Navbar />
<Routes>
<Route path="/" element={<Home />} />
<Route path="/experiences" element={<Experiences />} />
</Routes>
</Router>
react-router-dom#6.4 Data APIs
If you are using the new Data routers you can hit this issue if you attempt to render a header/navbar outside the RouterProvider component. For this you can create a layout route that is part of the routing configuration passed to createBrowserRouter (and other variants).
Example:
const AppLayout = () => (
<>
<Navbar />
<Outlet />
</>
);
const router = createBrowserRouter(
createRoutesFromElements(
<Route element={<AppLayout />}>
<Route path="/" element={<Home />} />
<Route path="/experiences" element={<Experiences />} />
</Route>
)
);
...
<RouterProvider router={router} />

Answer 2

in React Route v6 you can solve this giving the route context to your entire App with <BrowserRouter>
This is an complete example of index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import { App } from './components/App/App.jsx';
ReactDOM.render(
<React.StrictMode>
<BrowserRouter> //that is the key
<App />
</BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);

Answer 3

If you are still having problem with this one, it is because react-router-dom relies on React context to work when you try to unit-test it. This makes <Link /> or <Route /> obsolete.
Try reading the react-router-dom documentation.
Instead of using
render(<Example />)
that have either or inside it, you can try
render(<MemoryRouter>
<Example />
</MemoryRouter>)
Hope this solves your problem

Answer 4

In react-router-dom:6.x and react:18.x, we should use the Router in the following way to resolve the issue:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import { App } from './App.js';
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
<React.StrictMode>
<Router> // Router
<App /> // Application
</Router>
</React.StrictMode>
);

Answer 5

Links are inside Navbar &
Navbar is outside of Router
=> links are outside of Router => Router will not manage Links
Solution
Move the Navbar into Router section. Example:
<Router>
<Navbar /> // <===========
<Routes>
<Route />
<Route />
</Routes>
</Router>

Answer 6

Wrap navbar with BrowserRouter
import { BrowserRouter, Routes, Route } from "react-router-dom";
<BrowserRouter>
<AppNavBar />
<Routes>
<Route path="/" element={<Home />} />
<Route path="/wall" element={<WallPost />} />
</Routes>
</BrowserRouter>

Answer 7

Install in your project React Router v6.
npm install react-router-dom#6
Then use BrowserRouter in your index.js file, below like this:
import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import { BrowserRouter } from 'react-router-dom';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>
);

Answer 8

React Router v6 this problem common one, you can simply replace "index.js" code. you will got solution-
import React from 'react';
import { createRoot } from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import { BrowserRouter } from 'react-router-dom';
const container = document.getElementById('root');
const root = createRoot(container);
root.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>
);

Answer 9

This error happens because Link component needs to reach out to react-router context object. Your Navbar component is using Link component but Navbar is not wrapped by router context.
A similar error happens in a testing environment. If you have a component that uses Link component and if you render this component in a testing environment, you will get the same error because Link component needs to access a router context. In the case of test environment:
import { render } from "#testing-library/react";
// this will throw same error
test("testing", () => {
render(<ComponentRendersLink/>);
});
Solution in this case to wrap it with a router
// there are more router options
import { MemoryRouter } from "react-router-dom";
render(
<MemoryRouter>
<ComponentRendersLink />
</MemoryRouter>
);

Answer 10

This is very much an edge case, but in my case it turned out a lib I develop had react-router-dom: 6.0.2 installed and project that uses it v6.3.0

Answer 11

Your links just needs to be within a BrowserRouter component since you use v6
After importing
<BrowserRouter>
<Link to='page'>
</BrowserRouter>
