React Router 2026 — Multi-Page Apps, URL Params & useNavigate | Web Dev Series #011

React Video 4 — React Router. This is how you build multi-page apps in React. Every real React app has multiple pages. A home page, a list page, a detail page, a 404. React Router connects your components to the browser URL so users can navigate without a full page reload — and so every page has a shareable link. In this video: setting up React Router, navigating with Link and NavLink, reading URL parameters with useParams, programmatic navigation with useNavigate, query strings with useSearchParams, nested routes and layouts with Outlet, and 404 handling. We extend the User Dashboard from Video 3 with full routing — clicking a user card opens their detail page with their posts.
