Uncaught Error: useNavigate() may be used only in the context of a component. - What is it that I am doing wrong?

Question

I am trying to create an authenticated route and I did the following but this throws an error saying

2Transition.js:251 Uncaught Error: useNavigate() may be used only in the context of a <Router> component.

What is it that I am doing wrong?

import { BrowserRouter, Routes, Route, useNavigate } from "react-router-dom";


function App() {
     const navigate = useNavigate();
     return(
           <BrowserRouter>
                 <Routes>
                        <Route
                           path={APP_ROUTES.DASHBOARD}
                            element={
                             isUserLoggedIn() ? <Dashboard /> : 
                                                <>pp{navigate(APP_ROUTES.LOGIN)}</>
                            }
                        />
                 </Routes>
          </BrowserRouter>
     )
}

What would be the best way to add a couple of authenticated routes?

Answer 1

Issue

The App component is rendering the router that provides the routing context that the useNavigate hook needs.

Solution

Move BrowserRouter higher in the ReactTree so that it can provide a routing context to components below it. Wrapping App component with a router is correct if you want to use any react-router-dom hooks in the App component.

import React from 'react';
import { BrowserRouter } from 'react-router-dom';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById('root')
);

...

import { Routes, Route, useNavigate } from "react-router-dom";

function App() {
  const navigate = useNavigate();
  return (
    <Routes>
      <Route
        path={APP_ROUTES.DASHBOARD}
        element={isUserLoggedIn()
          ? <Dashboard />
          : <>pp{navigate(APP_ROUTES.LOGIN)}</>
        }
      />
    </Routes>
  );
}

See How to Create a Protected Route

Answer 2

You are trying to use useNavigate() inside the App's component that is not inside a BrowserRouter because the BrowserRouter is inside the App's component and not around.

Answer 3

As the error suggests, you are using a hook in a component that isn't inside the <BrowserRouter>.

A potential solution would be to build a ProtectedRoute component

const ProtectedRoute = ({ children }) => {
  if (! isUserLoggedIn()) {
    return <Navigate to={APP_ROUTES.LOGIN} replace />;
  }

  return children;
};

and wrap your route around it:

       <Route
          path="home"
          element={
            <ProtectedRoute>
              <Dashboard />
            </ProtectedRoute>
          }
        />
