SvelteKit Framework
Full-stack framework providing SSR/CSR hybrid rendering, file-based routing, and built-in performance optimizations.
Architecture
The Stavily Web UI is built on a modern, scalable architecture that leverages SvelteKit’s full-stack capabilities to deliver high-performance user experiences across all devices and network conditions.

Key Technologies
Section titled “Key Technologies”TypeScript
Type-safe development ensuring better reliability and developer experience.
TailwindCSS
Utility-first CSS framework for consistent, responsive styling.
Socket.io
Real-time bidirectional communication for live updates and monitoring.
Component Architecture
Section titled “Component Architecture”Component Organization
Section titled “Component Organization”The UI follows a hierarchical component structure for maintainability and reusability:
- Layout Components: App shell, navigation, headers
- Page Components: Route-specific components with data loading
- Feature Components: Business logic components (workflows, agents)
- UI Components: Reusable design system elements
- Utility Components: Small, focused helper components
API Integration
Section titled “API Integration”Communication Patterns
Section titled “Communication Patterns”The Web UI communicates with backend services through multiple protocols:
- REST APIs: Standard HTTP endpoints for CRUD operations
- WebSocket: Real-time bidirectional communication
- GraphQL: Efficient data fetching with reduced over-fetching

Styling & Theming
Section titled “Styling & Theming”Design System
Section titled “Design System”The UI implements a consistent design system with:
- TailwindCSS: Utility-first styling approach
- Dark Mode: Built-in light/dark theme support
- Responsive Design: Mobile-first responsive layouts
- Accessibility: WCAG 2.1 AA compliant components
Performance & Optimization
Section titled “Performance & Optimization”Key Optimizations
Section titled “Key Optimizations”- Code Splitting: Automatic bundle splitting for optimal loading
- Lazy Loading: On-demand component loading for better performance
- Image Optimization: Automatic responsive image handling
- Caching: Browser and API-level caching strategies
Performance Goals
Section titled “Performance Goals”- < 2 seconds initial page load time
- < 500ms navigation between pages
- 95+ Lighthouse performance score
Security & Deployment
Section titled “Security & Deployment”Security Measures
Section titled “Security Measures”- Content Security Policy: Strict CSP headers
- Authentication: OAuth2/OIDC integration
- Authorization: Role-based access control
- Data Protection: Encryption in transit and at rest
Deployment Strategy
Section titled “Deployment Strategy”- Automated CI/CD: GitHub Actions for testing and deployment
- Containerized: Docker-based deployment
- Monitoring: Real-time performance and error tracking
