Why Am I Getting the \'[PrivateRoute] is Not a Component\' Error in React Router v6?

React Router v6 Error: [PrivateRoute] is Not a Component

When using React Router v6 and creating private routes, developers may encounter an error stating, "[PrivateRoute] is not a component. All component children of must be a or ."

Origin of the Problem

This error arises when the "PrivateRoute" component is not being properly rendered as a child of the "" component within the "" component.

Solution

To resolve this issue, ensure that the PrivateRoute component is defined as a nested child of the Route component within the Routes component, as seen below:

<code class="javascript">// PrivateRoute.js
import React from "react";
import { Navigate, Outlet } from "react-router-dom";

const PrivateRoute = () => {
  const auth = null; // Determine if authorized

  // Return outlet if authorized, navigate to login otherwise
  return auth ? <Outlet /> : <Navigate to="/login" />;
};

// App.js
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>
  );
};</code>

In this revised code:

• PrivateRoute is nested within Route, which is in turn nested within Routes.
• The PrivateRoute component determines authorization and displays the Outlet component (child elements) if authorized.
• If unauthorized, PrivateRoute navigates to a login page.
