## Key Components

### Appwrite Client (`src/lib/appwrite.js`)

Central configuration for Appwrite SDK:

```javascript theme={null}
import { Client, Databases, Storage, Account } from 'appwrite';

const client = new Client()
  .setEndpoint(import.meta.env.VITE_APPWRITE_ENDPOINT)
  .setProject(import.meta.env.VITE_APPWRITE_PROJECT_ID);

export const databases = new Databases(client);
export const storage = new Storage(client);
export const account = new Account(client);
```

### Database Service Pattern

Each feature has a dedicated service file:

```javascript theme={null}
// src/lib/blogService.js
import { databases, ID, Query } from './appwrite';

const DATABASE_ID = import.meta.env.VITE_APPWRITE_DATABASE_ID;
const COLLECTION_ID = 'blogs';

export const blogService = {
  async list(queries = []) {
    return await databases.listDocuments(
      DATABASE_ID,
      COLLECTION_ID,
      queries
    );
  },
  
  async get(id) {
    return await databases.getDocument(
      DATABASE_ID,
      COLLECTION_ID,
      id
    );
  },
  
  async create(data) {
    return await databases.createDocument(
      DATABASE_ID,
      COLLECTION_ID,
      ID.unique(),
      data
    );
  },
  
  async update(id, data) {
    return await databases.updateDocument(
      DATABASE_ID,
      COLLECTION_ID,
      id,
      data
    );
  },
  
  async delete(id) {
    return await databases.deleteDocument(
      DATABASE_ID,
      COLLECTION_ID,
      id
    );
  }
};
```

### Context Providers

Global state management using React Context:

```javascript theme={null}
// src/context/AuthContext.jsx
import { createContext, useContext, useState, useEffect } from 'react';
import { account } from '../lib/appwrite';

const AuthContext = createContext();

export function AuthProvider({ children }) {
  const [user, setUser] = useState(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    checkUser();
  }, []);

  async function checkUser() {
    try {
      const session = await account.get();
      setUser(session);
    } catch {
      setUser(null);
    }
    setLoading(false);
  }

  return (
    <AuthContext.Provider value={{ user, loading, checkUser }}>
      {children}
    </AuthContext.Provider>
  );
}

export const useAuth = () => useContext(AuthContext);
```

## Routing Structure

```javascript theme={null}
// src/App.jsx
<Routes>
  {/* Public Routes */}
  <Route path="/" element={<HomePage />} />
  <Route path="/blogs" element={<BlogsPage />} />
  <Route path="/blog/:slug" element={<BlogPage />} />
  <Route path="/projects" element={<ProjectsPage />} />
  <Route path="/project/:slug" element={<ProjectPage />} />
  <Route path="/shop" element={<ShopPage />} />
  
  {/* Shortlink Redirect */}
  <Route path="/:path" element={<ShortlinkRedirect />} />
  
  {/* Admin Routes (Protected) */}
  <Route path="/admin" element={<AdminLayout />}>
    <Route index element={<Dashboard />} />
    <Route path="blogs" element={<BlogManagement />} />
    <Route path="projects" element={<ProjectManagement />} />
    <Route path="shortlinks" element={<ShortlinkManagement />} />
    {/* ... more admin routes */}
  </Route>
</Routes>
```

## State Management

| State Type   | Solution                   | Use Case              |
| ------------ | -------------------------- | --------------------- |
| Server State | Direct Appwrite calls      | Database operations   |
| Auth State   | AuthContext                | User session          |
| Cart State   | CartContext + localStorage | Shopping cart         |
| UI State     | useState/useReducer        | Component-level state |

## Performance Optimizations

### Code Splitting

```javascript theme={null}
// Lazy load admin pages
const BlogManagement = lazy(() => import('./pages/Admin/BlogManagement'));
const ProjectManagement = lazy(() => import('./pages/Admin/ProjectManagement'));
```

### Image Optimization

* Lazy loading for images below the fold
* WebP format support
* Responsive image sizes

### Font Loading

```javascript theme={null}
// Dynamic Google Font loading
const loadGoogleFont = (fontFamily) => {
  const link = document.createElement('link');
  link.href = `https://fonts.googleapis.com/css2?family=${fontFamily}&display=swap`;
  link.rel = 'stylesheet';
  document.head.appendChild(link);
};
```

## Security Considerations

| Concern        | Solution                              |
| -------------- | ------------------------------------- |
| Authentication | Appwrite session management           |
| Authorization  | Collection-level permissions          |
| XSS Prevention | DOMPurify for rich text               |
| CORS           | Appwrite platform configuration       |
| Secrets        | Environment variables (never in code) |

## Build Configuration

### Vite Config (`vite.config.js`)

```javascript theme={null}
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [react()],
  build: {
    rollupOptions: {
      output: {
        manualChunks: {
          vendor: ['react', 'react-dom', 'react-router-dom'],
          appwrite: ['appwrite'],
        }
      }
    }
  }
});
```

### Tailwind Config (`tailwind.config.js`)

```javascript theme={null}
export default {
  content: ['./index.html', './src/**/*.{js,jsx}'],
  theme: {
    extend: {
      colors: {
        primary: '#1E8479',
        secondary: '#105652',
      }
    }
  },
  plugins: []
};
```
