Migrating to React Router v6: A complete guide

Upgrading from React Router v5 to v6 involves addressing several changes and improvements in the library, which seeks to enhance simplicity, consistency, and efficiency. React Router v6 introduces new hooks like useNavigate, replacing useHistory for navigation, and simplifies the route setup by removing the need for Switch, using Routes instead. It supports relative route paths and nested routing, reducing the code complexity and boilerplate associated with v5's useRouteMatch. Key changes also include modifying the NavLink component for styling active links and the removal of certain features like usePrompt and nested routers, which were deemed ambiguous or faulty. Despite some breaking changes, the upgrade is advantageous due to its reduced bundle size, streamlined API, and improved developer experience, although migrating complex apps with deprecated features may require careful planning or incremental updates.
