Architecture Overview

System Design

This project follows a component-based architecture with clear separation of concerns.

Technology Stack

• Framework: Astro 5.11.0
• Styling: Tailwind CSS 3.4.4 with design tokens
• Language: TypeScript (strict mode)
• Build Tool: Vite
• Package Manager: pnpm

Design Principles

1. Performance First: Every decision prioritizes performance
2. Progressive Enhancement: Works without JavaScript
3. Accessibility: WCAG AA compliance mandatory
4. Type Safety: Full TypeScript coverage
5. Component Reusability: DRY principle

molecules/ Card.astro # Combinations of atoms FormField.astro SearchBar.astro

organisms/ Header.astro # Complete sections Hero.astro Footer.astro

Component Guidelines

1. Props Interface: Every component has TypeScript interface
2. Composition: Prefer slots over props
3. Styling: Use Tailwind utilities with design tokens
4. Accessibility: ARIA labels and keyboard navigation

• Critical CSS extraction
• Tree shaking

Runtime Optimization

• Zero JavaScript baseline
• Progressive enhancement
• Lazy loading for images
• Service worker caching

Security Architecture

Headers Configuration

X-Frame-Options: DENY X-Content-Type-Options: nosniff Content-Security-Policy: strict

Environment Variables

• Secrets in .env only
• Public vars prefixed with PUBLIC_
• Validation on build

Deployment Architecture

CI/CD Pipeline

1. Push to main branch
2. GitHub Actions triggered
3. Tests run (type, lint, build)
4. Deploy to Cloudflare Pages
5. Invalidate CDN cache

Environments

• Production: main branch

Component Documentation

Overview

All components follow Atomic Design principles and are built with TypeScript for type safety.

Component Catalog

Atoms

Atom: Button

The base button component supporting multiple variants and sizes.

astro

import Button from ’@/components/atoms/Button.astro’

Action

Variant Pattern

typescript // Define variants with const assertion const variants = { primary: ‘bg-primary-600 text-white’, secondary: ‘bg-gray-100 text-gray-900’, ghost: ‘bg-transparent hover:bg-gray-100’, } as const;

type Variant = keyof typeof variants;

Accessibility Pattern

astro

<button aria-label={ariaLabel || children} aria-pressed={isActive} aria-expanded={isOpen}

Testing Components

Visual Testing

components/Button/Button.test.astro

import Button from './Button.astro'

<div class="test-grid">
  <!-- Test all variants -->
  {['primary', 'secondary', 'ghost'].map(variant => (
    <Button variant={variant}>
      {variant} Button
    </Button>
  ))}

  <!-- Test all sizes -->

\{\['sm', 'md', 'lg'].map(size => ( <Button size={size}>
Size \{size} </Button>
))}

  <!-- Test states -->

<Button disabled>Disabled</Button> <Button href="./link">Link Button</Button>

</div>

Best Practices

1. Always use TypeScript interfaces for props
2. Provide default values for optional props
3. Use semantic HTML elements
4. Include focus states for keyboard navigation
5. Test with screen readers
6. Document edge cases
