Covers the hooks and patterns you need for Clerk authentication in React SPAs built with Vite or Create React App. You get useAuth, useUser, and useClerk hooks, protected route implementations for React Router v6/v7, and custom sign-in flow examples. The mental model section is genuinely helpful: it hammers home that isLoaded must be true before you trust isSignedIn, which catches the most common bug people hit with client-only auth. The pitfall table is practical too. If you're building a React SPA with Clerk and need more than the prebuilt components, this gives you the patterns to roll your own flows without fumbling through docs.
