Frontend Architecture Skill

When to Use This Skill

Use this skill when you need to:

• Design scalable application architecture - Structure large-scale frontend applications with maintainable patterns
• Choose architectural patterns - Select appropriate design patterns (MVC, MVVM, Flux) for your use case
• Implement state management - Design state architecture for complex applications
• Structure component hierarchies - Create reusable, composable component systems
• Optimize build processes - Configure bundlers and build tools for optimal performance
• Plan testing strategies - Architect comprehensive testing approaches across layers
• Design module systems - Implement code splitting, lazy loading, and module boundaries
• Scale codebases - Establish conventions for growing teams and applications
• Refactor legacy code - Migrate to modern architectural patterns
• Performance optimization - Structure applications for optimal load times and runtime performance

Core Concepts

1. Component Architecture

Component-based architecture is the foundation of modern frontend development, enabling modularity and reusability.

Component Design Principles

Single Responsibility Principle Each component should have one clear purpose:

// Bad: Component doing too much
function UserDashboard() {
  const [user, setUser] = useState(null);
  const [posts, setPosts] = useState([]);
  const [notifications, setNotifications] = useState([]);
  const [settings, setSettings] = useState({});

  // Mixing concerns: data fetching, rendering, business logic
  useEffect(() => {
    fetch('/api/user').then(r => r.json()).then(setUser);
    fetch('/api/posts').then(r => r.json()).then(setPosts);
    fetch('/api/notifications').then(r => r.json()).then(setNotifications);
  }, []);

  return (
    <div>
      <header>{user?.name}</header>
      <PostList posts={posts} />
      <NotificationBell count={notifications.length} />
      <SettingsPanel settings={settings} />
    </div>
  );
}

// Good: Separated concerns
function UserDashboard() {
  return (
    <DashboardLayout>
      <UserHeader />
      <UserPosts />
      <UserNotifications />
      <UserSettings />
    </DashboardLayout>
  );
}

function UserPosts() {
  const { posts, loading } = useUserPosts();

  if (loading) return <PostsLoading />;
  return <PostList posts={posts} />;
}

Composition Over Inheritance

// Using composition for flexibility
interface ButtonProps {
  children: React.ReactNode;
  onClick?: () => void;
  variant?: 'primary' | 'secondary';
}

function Button({ children, onClick, variant = 'primary' }: ButtonProps) {
  return (
    <button className={`btn btn-${variant}`} onClick={onClick}>
      {children}
    </button>
  );
}

// Compose complex components
function IconButton({ icon, ...props }: ButtonProps & { icon: string }) {
  return (
    <Button {...props}>
      <Icon name={icon} />
      {props.children}
    </Button>
  );
}

function LoadingButton({ loading, ...props }: ButtonProps & { loading: boolean }) {
  return (
    <Button {...props} disabled={loading}>
      {loading ? <Spinner /> : props.children}
    </Button>
  );
}

Container vs Presentational Components

// Presentational Component (Pure UI)
interface UserCardProps {
  user: User;
  onEdit: () => void;
  onDelete: () => void;
}

function UserCard({ user, onEdit, onDelete }: UserCardProps) {
  return (
    <div className="user-card">
      <img src={user.avatar} alt={user.name} />
      <h3>{user.name}</h3>
      <p>{user.email}</p>
      <div className="actions">
        <button onClick={onEdit}>Edit</button>
        <button onClick={onDelete}>Delete</button>
      </div>
    </div>
  );
}

How to use frontend-architecture on Cursor
AI-first code editor with Composer
1
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add frontend-architecture
2
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
$npx skills add https://github.com/manutej/luxor-claude-marketplace --skill frontend-architecturecopy
The skills CLI fetches frontend-architecture from GitHub repository manutej/luxor-claude-marketplace and configures it for Cursor.
3
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
◆ Which agents do you want to install to?
│
│ ── Universal (.agents/skills) ── always included ────
│   • Amp
│   • Antigravity
│   • Cline
│   • Codex
│ ●Cursor(selected)
│   • Cursor
│   • Windsurf
4
Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/frontend-architecture
Reload or restart Cursor to activate frontend-architecture. Access the skill through slash commands (e.g., /frontend-architecture) or your agent's skill management interface.
⚠
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
