Introduction to Private Routes

Private Routes are essential for protecting sensitive parts of your React application. They ensure that only authenticated users can access certain routes, such as dashboards, profile pages, or admin panels. This guide will show you how to implement secure route protection using React Router and Redux Toolkit.

Key Concept: A Private Route acts as a wrapper component that checks the user's authentication status before rendering protected content. If the user isn't authenticated, they are redirected to the sign-in page.

Understanding Key Components

Core Components Overview

Outlet: A React Router component that renders child route elements
Navigate: A component for declarative navigation
useSelector: A Redux hook for accessing state

Important: The useSelector hook comes from Redux Toolkit, which we covered in our previous guide. It's crucial for accessing the authentication state.

Implementation Guide

Step 1: Create the PrivateRoute Component


import { useSelector } from 'react-redux';
import { Outlet, Navigate } from 'react-router-dom';

export default function PrivateRoute() {
    const { currentUser } = useSelector((state) => state.user);
    return currentUser ?  : ;
}

Code Breakdown:

useSelector extracts currentUser from Redux state
Outlet renders child routes when user is authenticated
Navigate redirects to sign-in page when user isn't authenticated

Step 2: Implement Route Protection


<Route element={<PrivateRoute />}>
    <Route path="/dashboard" element={<Dashboard />} />
</Route>

Important Note: The PrivateRoute component must be placed as a parent route with protected routes as children.

Advanced Usage and Best Practices

1. Role-Based Access Control


export function RoleBasedRoute({ requiredRole }) {
    const { currentUser, userRole } = useSelector((state) => state.user);
    return currentUser && userRole === requiredRole 
        ? <Outlet /> 
        : <Navigate to='/unauthorized' />;
}

2. Custom Redirect Paths


export function PrivateRoute({ redirectPath = '/sign-in' }) {
    const { currentUser } = useSelector((state) => state.user);
    return currentUser ? <Outlet /> : <Navigate to={redirectPath} />;
}

Frequently Asked Questions

1. What's the difference between useNavigate and Navigate?

While both handle navigation, they serve different purposes:

useNavigate: A hook for programmatic navigation (e.g., after form submission)
Navigate: A component for declarative navigation based on conditions

2. Why use Outlet instead of directly rendering components?

Outlet is specifically designed for nested routing in React Router v6. It:

Maintains proper route hierarchy
Handles nested route rendering automatically
Preserves layout components

3. How to handle loading states?


export function PrivateRoute() {
    const { currentUser, loading } = useSelector((state) => state.user);
    if (loading) return <LoadingSpinner />;
    return currentUser ? <Outlet /> : <Navigate to='/sign-in' />;
}
