Layout Components

This document describes the layout components that form the structure of the Dotcom Arcade application.

Public pages use PortalLayout instead of AppShell; see Discovery Portal. AppShell remains for settings and admin pages.

AppShell

Main application layout container that wraps all pages.

Location

D:\Repositories\Personal\flashpoint-web\frontend\src\components\layout\AppShell.tsx

Purpose

Provides the main application structure with header and sidebar navigation.

Props

interface AppShellProps {
  children: ReactNode;
}

Implementation

export function AppShell({ children }: AppShellProps) {
  const sidebarOpen = useUIStore((state) => state.sidebarOpen);

  return (
    <div className="flex flex-col h-screen bg-background text-foreground">
      <Header />

      <div className="flex flex-1 overflow-hidden">
        <Sidebar isOpen={sidebarOpen} />

        <main className="flex-1 overflow-auto bg-background pt-6">
          {children}
        </main>
      </div>
    </div>
  );
}

Features

• Fixed Height Layout - Uses h-screen to fill viewport
• Flexbox Structure - Column layout with header and content
• Overflow Management - Prevents content from overflowing viewport

Navigation Structure

Game Navigation

const gameNavItems: NavItem[] = [
  { path: '/', icon: Home, label: 'Home' },
  { path: '/animations', icon: Film, label: 'Animations' },
  { path: '/browse', icon: Gamepad2, label: 'Browse' },
];

Library Navigation (Hidden for Guests)

const libraryNavItems: NavItem[] = [
  { path: '/favorites', icon: Heart, label: 'Favorites' },
  { path: '/playlists', icon: ListIcon, label: 'Playlists' },
];

Management Section (Admin Only)

<RoleGuard permissions={['users.read', 'roles.read', 'activities.read']}>
  <div className="space-y-1">
    <RoleGuard permission="users.read">
      <Link to="/users">Users</Link>
    </RoleGuard>

    <RoleGuard permission="roles.read">
      <Link to="/roles">Roles</Link>
    </RoleGuard>

    <RoleGuard permission="activities.read">
      <Link to="/activities">Activity Logs</Link>
    </RoleGuard>
  </div>
</RoleGuard>

Bottom Section (Dashboard & Settings)

<div className="border-t p-4">
  <Link to="/dashboard">
    <BarChart3 size={20} />
    Dashboard
  </Link>

  <Link to="/settings">
    <Settings size={20} />
    Settings
  </Link>
</div>

Active Route Detection

const isNavItemActive = (item: NavItem) => {
  const itemPath = item.path.split('?')[0];
  const itemQuery = item.path.split('?')[1];

  if (itemQuery) {
    // Exact match including query params
    return (
      location.pathname === itemPath && location.search === `?${itemQuery}`
    );
  }

  return location.pathname === itemPath;
};

Mobile Behavior

Swipe Gesture

const sidebarRef = useSwipeGesture<HTMLElement>({
  onSwipeLeft: () => {
    if (window.innerWidth < 1024) {
      setSidebarOpen(false);
    }
  },
  minSwipeDistance: 50,
});

Auto-Close on Navigation

useEffect(() => {
  if (window.innerWidth < 1024) {
    setSidebarOpen(false);
  }
}, [location.pathname, setSidebarOpen]);

Backdrop Overlay

{isOpen && (
  <div
    className="fixed inset-0 bg-black/50 z-30 lg:hidden backdrop-blur-sm"
    onClick={handleBackdropClick}
    aria-hidden="true"
  />
)}

Responsive CSS Classes

<aside
  className={cn(
    'bg-card border-r flex flex-col overflow-hidden',
    sidebarCollapsed ? 'w-16' : 'w-64',
    // Mobile: fixed positioning with slide-in
    'lg:relative fixed inset-y-0 left-0 z-40',
    'transition-all duration-500 ease-in-out',
    'lg:translate-x-0',  // Always visible on desktop
    isOpen ? 'translate-x-0' : '-translate-x-full'  // Slide on mobile
  )}
>

Collapsed State Behavior

When sidebarCollapsed is true:

• Width: 64px (w-16)
• Icons only (no text)
• Tooltips on hover (via title attribute)
• Centered icons
• Management section label hidden

Layout State Management

Layout state is managed via the useUIStore Zustand store:

interface UIState {
  sidebarOpen: boolean;
  sidebarCollapsed: boolean;
  setSidebarOpen: (open: boolean) => void;
  toggleSidebarOpen: () => void;
  setSidebarCollapsed: (collapsed: boolean) => void;
  toggleSidebarCollapsed: () => void;
}

State Persistence

UI state is persisted to localStorage:

persist(
  (set) => ({
    /* ... */
  }),
  {
    name: 'flashpoint-ui-state',
    partialize: (state) => ({
      sidebarCollapsed: state.sidebarCollapsed,
      // sidebarOpen is intentionally not persisted (session-only)
    }),
  }
);

Styling and Theming

Tailwind Classes

Layout components use Tailwind utility classes:

• bg-card - Card background color (theme-aware)
• border-border - Border color (theme-aware)
• text-foreground - Text color (theme-aware)
• bg-primary/10 - Primary color with opacity

Custom CSS Variables

Applied via ThemeStore:

• --primary - Primary theme color
• --background - Background color
• --foreground - Text color
• --card - Card background
• --muted - Muted text color

Accessibility

ARIA Labels

<Button
  aria-label="Toggle sidebar"
  title="Toggle sidebar width"
>
  <Menu />
</Button>

Keyboard Navigation

• Tab navigation works across all interactive elements
• Sidebar links are keyboard accessible
• Dropdowns support arrow key navigation

Screen Readers

• Proper semantic HTML (<header>, <nav>, <main>, <aside>)
• ARIA attributes on interactive elements
• Hidden decorative elements with aria-hidden="true"
