One sentence: Adding authentication endpoints and managing auth state across the app.
Trigger: when adding new auth-protected routes or API calls.
| Task | Pattern |
|---|---|
| Add auth provider | <AuthProvider> |
| Get auth state | useAuth() |
Wrap the app shell with AuthProvider to make useAuth available throughout the component tree.
import { AuthProvider } from '@/lib/auth';
ReactDOM.createRoot(document.getElementById('root')!).render(
<AuthProvider>
<App />
</AuthProvider>,
);
Call useAuth() anywhere inside a provider-wrapped tree to get the auth context without prop-drilling.
const { token, loading } = useAuth();
