What problem does it solve?

Authentication is a common requirement for web applications. This guide shows how to use TanStack Router to build protected routes and redirect users to login when they try to access them.

Core Features & Use Cases

• Protected routes via route.beforeLoad to guard access and redirect unauthenticated users.
• Redirect handling with login flow, including preserving the original destination for post-login navigation.
• Router context integration to share authentication state across nested routes and layouts.
• Support for non-redirected authentication flows where a login component is shown in place.

Quick Start

1. Create a protected route with a beforeLoad function that checks authentication and redirects to /login if not authenticated.
2. Use redirect({ to: '/login', search: { redirect: location.href } }) to return users after login.
3. Wire an AuthProvider or React context to supply isAuthenticated state across routes.
