React Router Patterns

SDK: @clerk/react-router v3+. Requires React Router v7.9+.

What Do You Need?

Task	Reference
Auth in loaders and actions	references/loaders-actions.md
Protected routes and redirects	references/protected-routes.md
SSR user data and session	references/ssr-auth.md

React Router v7 uses a middleware + loader pipeline. Clerk plugs into both layers:

Middleware (clerkMiddleware()) — runs on every request, attaches auth to context
rootAuthLoader — required in root.tsx to pass Clerk state to the client
getAuth(args) — called inside any loader/action to get the current user
