In React applications, protected (or private) routes are routes that are accessible only to authenticated users. They prevent unauthorized users from accessing certain pages like dashboards, profiles, or admin panels. Instead, unauthenticated users are redirected to a login page.
How It Works
Authentication State → The app stores user login state (e.g., in Context, Redux, or localStorage/JWT).
Route Guarding → A wrapper component checks if the user is authenticated before rendering the route.
Redirection → If not logged in, redirect to /login.
Example: ProtectedRoute Component
import { Navigate } from "react-router-dom";
function ProtectedRoute({ children }) {
const isAuth = localStorage.getItem("token"); // or from Context/Redux
return isAuth ? children : <Navigate to="/login" />;
}
Usage in Routes
import { Routes, Route } from "react-router-dom";
<Routes>
<Route path="/login" element={<Login />} />
<Route
path="/dashboard"
element={
<ProtectedRoute>
<Dashboard />
</ProtectedRoute>
}
/>
</Routes>
Here, only logged-in users can see Dashboard; others are redirected.
Key Points
Ensures security on the client-side UI.
Often paired with JWT tokens or session data.
Still requires backend validation (since client-side routes can be bypassed).
👉 In short, protected/private routes in React act as gatekeepers, allowing only authenticated users to access restricted pages while redirecting unauthenticated users.
Would you like me to also add a role-based protected route example (like admin-only access)?
