views-and-navigation

What problem does it solve?

Simplifies creating and maintaining Vaadin 25 Java/Flow views, routes, and navigation shells so developers avoid duplicated layout code, brittle routing, and inconsistent navigation behavior across the app.

Core Features & Use Cases

• Route and view creation: Guidance for @Route, @RouteAlias, @PageTitle, and deriving paths from view names.
• Layout and app shell composition: Best practices for AppLayout, @Layout, RouterLayout, nested layouts, @ParentLayout, and @RoutePrefix to build consistent headers, drawers, and SideNavs.
• Navigation patterns: Use RouterLink for accessibility, UI.navigate for programmatic flows, the "Your Own API" pattern for centralized navigation, and MenuConfiguration/@Menu for dynamic menus.
• Parameter handling and patterns: Advice for HasUrlParameter, route templates with regex, optional and wildcard parameters, query parameter handling, and master-detail scaffolds with SplitLayout.
• Use case: Build a MainLayout with a drawer SideNav that highlights nested routes, implement a CustomerDetailView that loads by route parameter, and support list filtering via query parameters.

Quick Start

Generate a Vaadin 25 Java CustomersView at route customers and a CustomerDetailView at route customer/:customerId, implement BeforeEnterObserver for parameter loading, and add a MainLayout using AppLayout with a SideNav populated from @Menu annotations.
