- Pattern Relationships: Visualize how patterns relate to each other with an interactive relationship graph
- Community Feedback: Review and discuss patterns with the community
- Pattern Tutorials: Learn how to implement patterns with step-by-step guides and video tutorials
- Responsive Design: Seamless experience across devices
- User Dashboard: Track favorite patterns and recent activity
- Frontend Framework: React
- Build Tool: Vite
- Type Safety: TypeScript
- UI Components: shadcn/ui (built on Radix UI primitives)
- Styling: Tailwind CSS
- Routing: React Router
- State Management: React Context API + React Query
- Icons: Lucide React
- Data Visualization: Recharts
- Form Handling: React Hook Form + Zod validation
- Node.js (v16.x or later)
- npm (v8.x or later)

Our state management approach uses a combination of:
- React Context API for global UI state
- TanStack React Query for server state
- Local Component State for UI-specific state
React Context Implementation:
// src/context/AppContext.tsx
import { createContext, useContext, useState, ReactNode } from 'react';
interface AppContextType {
theme: 'light' | 'dark';
toggleTheme: () => void;
user: User | null;
setUser: (user: User | null) => void;
isAuthenticated: boolean;
}
interface User {
id: string;
name: string;
email: string;
}
const AppContext = createContext<AppContextType | undefined>(undefined);
export function AppProvider({ children }: { children: ReactNode }) {
const [theme, setTheme] = useState<'light' | 'dark'>('light');
const [user, setUser] = useState<User | null>(null);
const toggleTheme = () => {
setTheme(prev => prev === 'light' ? 'dark' : 'light');
};
return (
<AppContext.Provider value={{
theme,
toggleTheme,
user,
setUser,
isAuthenticated: !!user
}}>
{children}
</AppContext.Provider>
);
}
export function useAppContext() {
const context = useContext(AppContext);
if (context === undefined) {
throw new Error('useAppContext must be used within an AppProvider');
}
return context;
}React Query for Data Fetching:
// src/hooks/usePatterns.ts
import { useQuery } from '@tanstack/react-query';
const fetchPatterns = async (filters = {}) => {
const queryString = new URLSearchParams(filters).toString();
const response = await fetch(`/api/patterns?${queryString}`);
if (!response.ok) {
throw new Error('Failed to fetch patterns');
}
return response.json();
};
export function usePatterns(filters = {}) {
return useQuery({
queryKey: ['patterns', filters],
queryFn: () => fetchPatterns(filters),
});
}
export function usePattern(id: string) {
return useQuery({
queryKey: ['pattern', id],
queryFn: async () => {
const response = await fetch(`/api/patterns/${id}`);
if (!response.ok) {
throw new Error('Failed to fetch pattern');
}
return response.json();
},
enabled: !!id,
});
}Our application uses React Router for client-side routing:
// src/App.tsx
import { BrowserRouter, Routes, Route } from 'react-router-dom';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { AppProvider } from './context/AppContext';
import { Toaster } from './components/ui/toaster';
// Pages
import Index from './pages/Index';
import Catalog from './pages/Catalog';
import PatternDetail from './pages/PatternDetail';
import Dashboard from './pages/Dashboard';
import Documentation from './pages/Documentation';
import SignIn from './pages/SignIn';
import SignUp from './pages/SignUp';
import NotFound from './pages/NotFound';
const queryClient = new QueryClient();
function App() {
return (
<QueryClientProvider client={queryClient}>
<AppProvider>
<BrowserRouter>
<Routes>
<Route path="/" element={<Index />} />
<Route path="/catalog" element={<Catalog />} />
<Route path="/pattern/:id" element={<PatternDetail />} />
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/documentation" element={<Documentation />} />
<Route path="/signin" element={<SignIn />} />
<Route path="/signup" element={<SignUp />} />
<Route path="*" element={<NotFound />} />
</Routes>
<Toaster />
</BrowserRouter>
</AppProvider>
</QueryClientProvider>
);
}

Client-Side Flow:
- User interacts with UI (clicks, inputs, navigation)
- React components update local state and trigger events
- React Query handles data fetching and caching
- React Context maintains global state (authentication, theme)
- Component re-renders display updated information
Server Communication Flow:
- React Query initiates API requests based on user actions
- API server processes requests and performs operations
- Server returns data/errors to the client
- React Query updates client cache with new data
- UI components re-render with updated information
Authentication Flow:
- User enters credentials on SignIn/SignUp pages
- Client sends auth request to API server
- Server validates credentials and returns JWT token
- Client stores token in secure storage (e.g., HttpOnly cookies)
- Subsequent requests include auth token in headers
- Protected routes check auth status before rendering
