This course offers an in-depth exploration of React Router, the library that provides navigational components for React applications. It concentrates on the principles of declarative routing, where routes are treated as components, allowing for dynamic route matching and lazy code loading. The curriculum provides a deep dive into the API of React Router, elucidating the intricacies of route configuration, link components, route protection with authentication, and handling not-found scenarios with custom hooks and redirects. By examining the core concepts and advanced techniques of React Router, participants are equipped to architect and implement robust navigation solutions in their React applications.
