# Patterns

Page layouts, navigation patterns, and application templates for dark-themed React applications.

## App Shell

The main application layout with sidebar navigation:

```tsx
import { motion } from 'framer-motion';
import { type ReactNode } from 'react';
import { Sidebar } from './Sidebar';

interface AppShellProps {
  children: ReactNode;
}

export function AppShell({ children }: AppShellProps) {
  return (
    <div className="flex min-h-screen bg-neutral-bg1">
      <Sidebar />
      <main className="flex-1 ml-64">
        {children}
      </main>
    </div>
  );
}
```

---

## Responsive App Shell

Mobile-responsive layout: desktop shows fixed sidebar, mobile shows hamburger menu with slide-in drawer.

**Breakpoint:** `lg` (1024px) — sidebar visible on desktop, hidden on mobile.

```tsx
import { motion, AnimatePresence } from 'framer-motion';
import { type ReactNode, useState } from 'react';
import { Sidebar } from './Sidebar';
import { MobileHeader } from './MobileHeader';
import { MobileDrawer } from './MobileDrawer';

interface ResponsiveAppShellProps {
  children: ReactNode;
}

export function ResponsiveAppShell({ children }: ResponsiveAppShellProps) {
  const [drawerOpen, setDrawerOpen] = useState(false);

  return (
    <div className="flex min-h-screen bg-neutral-bg1">
      {/* Desktop sidebar - hidden on mobile */}
      <div className="hidden lg:block">
        <Sidebar />
      </div>

      {/* Mobile header - visible only on mobile */}
      <MobileHeader onMenuClick={() => setDrawerOpen(true)} />

      {/* Mobile drawer */}
      <MobileDrawer open={drawerOpen} onClose={() => setDrawerOpen(false)} />

      {/* Main content - adjusted margins for desktop sidebar and mobile header */}
      <main className="flex-1 lg:ml-64 pt-14 lg:pt-0 pb-safe-bottom">
        {children}
      </main>
    </div>
  );
}
```

## Mobile Header

Fixed top header for mobile with hamburger menu toggle. Uses 44px minimum touch target.

```tsx
import { Bars3Icon } from '@heroicons/react/24/outline';

interface MobileHeaderProps {
  onMenuClick: () => void;
}

export function MobileHeader({ onMenuClick }: MobileHeaderProps) {
  return (
    <header className="fixed top-0 left-0 right-0 h-14 glass-panel flex items-center justify-between px-4 lg:hidden z-40">
      {/* Logo */}
      <div className="flex items-center gap-2">
        <img src="/logo.svg" alt="Logo" className="w-6 h-6" />
        <span className="text-base font-semibold text-text-primary">AppName</span>
      </div>

      {/* Hamburger menu - 44px touch target */}
      <button
        onClick={onMenuClick}
        className="min-w-touch min-h-touch flex items-center justify-center rounded-lg hover:bg-white/5 active:bg-white/10 transition-colors"
        aria-label="Open menu"
      >
        <Bars3Icon className="w-6 h-6 text-text-primary" />
      </button>
    </header>
  );
}
```

## Mobile Drawer

Animated slide-in navigation drawer for mobile. Includes backdrop and close button.

```tsx
import { motion, AnimatePresence } from 'framer-motion';
import { XMarkIcon } from '@heroicons/react/24/outline';
import { NavLink, useLocation } from 'react-router-dom';
import { clsx } from 'clsx';
import {
  HomeIcon,
  ChartBarIcon,
  Cog6ToothIcon,
  UsersIcon,
  FolderIcon,
} from '@heroicons/react/24/outline';

const navItems = [
  { path: '/', label: 'Dashboard', icon: HomeIcon },
  { path: '/analytics', label: 'Analytics', icon: ChartBarIcon },
  { path: '/projects', label: 'Projects', icon: FolderIcon },
  { path: '/team', label: 'Team', icon: UsersIcon },
  { path: '/settings', label: 'Settings', icon: Cog6ToothIcon },
];

interface MobileDrawerProps {
  open: boolean;
  onClose: () => void;
}

export function MobileDrawer({ open, onClose }: MobileDrawerProps) {
  const location = useLocation();

  return (
    <AnimatePresence>
      {open && (
        <>
          {/* Backdrop */}
          <motion.div
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
            transition={{ duration: 0.2 }}
            className="fixed inset-0 bg-black/60 backdrop-blur-sm z-50 lg:hidden"
            onClick={onClose}
          />

          {/* Drawer */}
          <motion.aside
            initial={{ x: '-100%' }}
            animate={{ x: 0 }}
            exit={{ x: '-100%' }}
            transition={{ type: 'spring', stiffness: 400, damping: 30 }}
            className="fixed left-0 top-0 bottom-0 w-72 glass-panel p-4 flex flex-col z-50 lg:hidden pl-safe-left"
          >
            {/* Header with close button */}
            <div className="flex items-center justify-between mb-6">
              <div className="flex items-center gap-2">
                <img src="/logo.svg" alt="Logo" className="w-8 h-8" />
                <span className="text-lg font-semibold text-text-primary">AppName</span>
              </div>
              <button
                onClick={onClose}
                className="min-w-touch min-h-touch flex items-center justify-center rounded-lg hover:bg-white/5 active:bg-white/10 transition-colors"
                aria-label="Close menu"
              >
                <XMarkIcon className="w-6 h-6 text-text-primary" />
              </button>
            </div>

            {/* Navigation */}

                    </motion.div>
                  </NavLink>
                );
              })}
            </nav>

          </motion.aside>
        </>
      )}
    </AnimatePresence>
  );
}
```

## Sidebar Navigation

Glass-effect sidebar with animated navigation items:

```tsx
import { motion } from 'framer-motion';
import { NavLink, useLocation } from 'react-router-dom';
import { clsx } from 'clsx';
import {
  HomeIcon,
  ChartBarIcon,
  Cog6ToothIcon,
  UsersIcon,
  FolderIcon,
} from '@heroicons/react/24/outline';

const navItems = [
  { path: '/', label: 'Dashboard', icon: HomeIcon },
  { path: '/analytics', label: 'Analytics', icon: ChartBarIcon },
  { path: '/projects', label: 'Projects', icon: FolderIcon },
  { path: '/team', label: 'Team', icon: UsersIcon },
  { path: '/settings', label: 'Settings', icon: Cog6ToothIcon },
];

export function Sidebar() {
  const location = useLocation();

  return (
    <aside className="fixed left-0 top-0 h-screen w-64 glass-panel p-4 flex flex-col">
      {/* Logo */}
      <div className="flex items-center gap-3 px-3 py-4 mb-6">
        <img src="/logo.svg" alt="Logo" className="w-8 h-8" />
        <span className="text-lg font-semibold text-text-primary">AppName</span>
      </div>

      {/* Navigation */}
      <nav className="flex-1 space-y-1">
        {navItems.map((item) => {
          const isActive = location.pathname === item.path;
          const Icon = item.icon;

          return (
            <NavLink key={item.path} to={item.path}>
              <motion.div
                className={clsx(
                  'relative flex items-center gap-3 px-3 py-2.5 rounded-lg',
                  'text-sm font-medium transition-colors duration-150',
                  isActive
                    ? 'text-text-primary'
                    : 'text-text-muted hover:text-text-secondary hover:bg-white/5'
                )}
                whileHover={{ x: 4 }}
                transition={{ type: 'spring', stiffness: 400, damping: 25 }}
              >
                {isActive && (
                  <motion.div
                    layoutId="activeNavItem"
                    className="absolute inset-0 bg-brand/20 border border-brand/30 rounded-lg"
                    transition={{ type: 'spring', stiffness: 500, damping: 30 }}
                  />
                )}
                <Icon className={clsx('w-5 h-5 relative z-10', isActive && 'text-brand')} />
                <span className="relative z-10">{item.label}</span>
              </motion.div>
            </NavLink>
          );
        })}
      </nav>

      {/* User profile at bottom */}
      <div className="mt-auto pt-4 border-t border-white/10">
        <div className="flex items-center gap-3 px-3 py-2">
          <div className="w-8 h-8 rounded-full bg-brand-subtle flex items-center justify-center">
            <span className="text-sm font-medium text-brand">JD</span>
          </div>
          <div className="flex-1 min-w-0">
            <p className="text-sm font-medium text-text-primary truncate">John Doe</p>
            <p className="text-xs text-text-muted truncate">john@example.com</p>
          </div>
        </div>
      </div>
    </aside>
  );
}
```

## Page Header

Reusable header component for pages:

```tsx
import { motion } from 'framer-motion';
import { type ReactNode } from 'react';

interface PageHeaderProps {
  title: string;
  description?: string;
  actions?: ReactNode;
}

export function PageHeader({ title, description, actions }: PageHeaderProps) {
  return (
    <motion.header
      initial={{ opacity: 0, y: -10 }}
      animate={{ opacity: 1, y: 0 }}
      transition={{ duration: 0.3 }}
      className="flex items-center justify-between mb-8"
    >
      <div>
        <h1 className="text-2xl font-semibold text-text-primary">{title}</h1>
        {description && (
          <p className="text-sm text-text-secondary mt-1">{description}</p>
        )}
      </div>
      {actions && <div className="flex items-center gap-3">{actions}</div>}
    </motion.header>
  );
}
```

---

## Page Transition Wrapper

Animate page transitions with route changes:

```tsx
import { motion } from 'framer-motion';
import { type ReactNode } from 'react';

interface PageTransitionProps {
  children: ReactNode;
}

const pageVariants = {
  initial: { opacity: 0, y: 20 },
  animate: { opacity: 1, y: 0 },
  exit: { opacity: 0, y: -20 },
};

export function PageTransition({ children }: PageTransitionProps) {
  return (
    <motion.div
      variants={pageVariants}
      initial="initial"
      animate="animate"
      exit="exit"
      transition={{ duration: 0.3, ease: 'easeOut' }}
    >
      {children}
    </motion.div>
  );
}
```

### Usage with React Router

```tsx
import { Routes, Route, useLocation } from 'react-router-dom';
import { AnimatePresence } from 'framer-motion';

function App() {
  const location = useLocation();

  return (
    <AppShell>
      <AnimatePresence mode="wait">
        <Routes location={location} key={location.pathname}>
          <Route path="/" element={<Dashboard />} />
          <Route path="/settings" element={<Settings />} />
        </Routes>
      </AnimatePresence>
    </AppShell>
  );
}
```

## Basic Page Template

Standard page layout with header and content area:

```tsx
import { PageTransition } from '../components/layout/PageTransition';
import { PageHeader } from '../components/layout/PageHeader';
import { Button } from '../components/ui';

export function BasicPage() {
  return (
    <PageTransition>
      <div className="p-8">
        <PageHeader
          title="Page Title"
          description="A brief description of this page"
          actions={
            <Button>Primary Action</Button>
          }
        />

        <div className="space-y-6">
          {/* Page content */}
        </div>
      </div>
    </PageTransition>
  );
}
```

## List Page Template

Page with search, filters, and data table:

```tsx
import { useState } from 'react';
import { motion } from 'framer-motion';

import { PageHeader } from '../components/layout/PageHeader';
import { Button, SearchInput, Card, Badge } from '../components/ui';
import { PlusIcon } from '@heroicons/react/20/solid';

interface Item {
  id: string;
  name: string;
  status: 'active' | 'inactive' | 'pending';
  createdAt: string;
}

const staggerContainer = {
  hidden: { opacity: 0 },
  visible: {
    opacity: 1,
    transition: { staggerChildren: 0.05 },
  },
};

const staggerItem = {
  hidden: { opacity: 0, y: 10 },
  visible: { opacity: 1, y: 0 },
};

export function ListPage() {
  const [search, setSearch] = useState('');
  const [items] = useState<Item[]>([
    { id: '1', name: 'Project Alpha', status: 'active', createdAt: '2024-01-15' },
    { id: '2', name: 'Project Beta', status: 'pending', createdAt: '2024-01-14' },
    { id: '3', name: 'Project Gamma', status: 'inactive', createdAt: '2024-01-13' },
  ]);

  const filteredItems = items.filter((item) =>
    item.name.toLowerCase().includes(search.toLowerCase())
  );

  return (
    <PageTransition>
      <div className="p-8">
        <PageHeader
          title="Projects"
          description="Manage your projects and their settings"

## Stagger Animation Patterns

Reusable animation variants for list items:

```tsx
// variants.ts
export const staggerContainer = {
  hidden: { opacity: 0 },
  visible: {
    opacity: 1,
    transition: {
      staggerChildren: 0.05,
      delayChildren: 0.1,
    },
  },
};

export const staggerItem = {
  hidden: { opacity: 0, y: 10 },
  visible: {
    opacity: 1,
    y: 0,
    transition: { duration: 0.2, ease: 'easeOut' },
  },
};

export const fadeInScale = {
  hidden: { opacity: 0, scale: 0.95 },
  visible: {
    opacity: 1,
    scale: 1,
    transition: { duration: 0.2, ease: 'easeOut' },
  },
};

export const slideInFromRight = {
  hidden: { opacity: 0, x: 20 },
  visible: {
    opacity: 1,
    x: 0,
    transition: { duration: 0.3, ease: 'easeOut' },
  },
};

export const slideInFromLeft = {
  hidden: { opacity: 0, x: -20 },
  visible: {
    opacity: 1,
    x: 0,
    transition: { duration: 0.3, ease: 'easeOut' },
  },
};
```

### Using Stagger Animations

```tsx
import { motion } from 'framer-motion';
import { staggerContainer, staggerItem } from './variants';

function ItemList({ items }) {
  return (
    <motion.ul
      variants={staggerContainer}
      initial="hidden"
      animate="visible"
      className="space-y-2"
    >
      {items.map((item) => (
        <motion.li key={item.id} variants={staggerItem}>
          {item.name}
        </motion.li>
      ))}
    </motion.ul>
  );
}
```

## Glass Panel Layouts

### Two-Column Layout with Glass Panels

```tsx
export function TwoColumnLayout() {
  return (
    <div className="flex gap-6 p-8">
      {/* Main content */}
      <div className="flex-1">
        <Card variant="glass">
          <h2 className="text-lg font-semibold text-text-primary mb-4">
            Main Content
          </h2>
          {/* Content */}
        </Card>
      </div>

      {/* Sidebar */}
      <aside className="w-80">
        <Card variant="glass" className="sticky top-8">
          <h3 className="text-sm font-medium text-text-muted uppercase tracking-wide mb-4">
            Quick Actions
          </h3>
          {/* Sidebar content */}
        </Card>
      </aside>
    </div>
  );
}
```

### Grid of Glass Cards

```tsx
export function CardGrid({ items }) {
  return (
    <motion.div
      variants={staggerContainer}
      initial="hidden"
      animate="visible"
      className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4"
    >
      {items.map((item) => (
        <motion.div key={item.id} variants={staggerItem}>
          <Card variant="glass" interactive>
            <h3 className="text-base font-medium text-text-primary">
              {item.title}
            </h3>
            <p className="text-sm text-text-secondary mt-2">
              {item.description}
            </p>
          </Card>
        </motion.div>
      ))}
    </motion.div>
  );
}
```

## Form Patterns

### Settings Form

```tsx
import { Button, Input, Select, Checkbox, Card } from '../components/ui';

export function SettingsForm() {
  return (
    <Card>
      <h2 className="text-lg font-semibold text-text-primary mb-6">
        Account Settings
      </h2>

      <form className="space-y-6">
        {/* Two-column grid for larger screens */}
        <div className="grid grid-cols-1 md:grid-cols-2 gap-6">
          <Input
            label="First Name"
            placeholder="Enter your first name"
          />
          <Input
            label="Last Name"
            placeholder="Enter your last name"
          />
        </div>

        <Input
          label="Email Address"
          type="email"
          placeholder="you@example.com"
        />

        <Select
          label="Timezone"
          placeholder="Select timezone"
          options={[
            { value: 'utc', label: 'UTC' },
            { value: 'pst', label: 'Pacific Time (PST)' },
            { value: 'est', label: 'Eastern Time (EST)' },
          ]}
        />

        <div className="border-t border-border pt-6">
          <h3 className="text-sm font-medium text-text-primary mb-4">
            Notification Preferences
          </h3>
          <div className="space-y-3">
            <Checkbox label="Email notifications" defaultChecked />
            <Checkbox label="Push notifications" />
            <Checkbox label="Weekly digest" defaultChecked />
          </div>
        </div>

        <div className="flex justify-end gap-3 pt-4">
          <Button variant="secondary">Cancel</Button>
          <Button>Save Changes</Button>
        </div>
      </form>
    </Card>
  );
}
```

## Empty States

```tsx
import { motion } from 'framer-motion';
import { FolderIcon } from '@heroicons/react/24/outline';
import { Button } from '../components/ui';

interface EmptyStateProps {
  icon?: typeof FolderIcon;
  title: string;
  description: string;
  action?: {
    label: string;
    onClick: () => void;
  };
}

export function EmptyState({ icon: Icon = FolderIcon, title, description, action }: EmptyStateProps) {
  return (
    <motion.div
      initial={{ opacity: 0, y: 20 }}
      animate={{ opacity: 1, y: 0 }}
      className="flex flex-col items-center justify-center py-16 px-4"
    >
      <div className="w-16 h-16 rounded-full bg-neutral-bg3 flex items-center justify-center mb-4">
        <Icon className="w-8 h-8 text-text-muted" />
      </div>
      <h3 className="text-lg font-medium text-text-primary mb-2">{title}</h3>
      <p className="text-sm text-text-secondary text-center max-w-sm mb-6">
        {description}
      </p>
      {action && (
        <Button onClick={action.onClick}>{action.label}</Button>
      )}
    </motion.div>
  );
}
```

### Usage

```tsx
<EmptyState
  title="No projects yet"
