🎨 Customization

Design Tokens

Primitive color scales (raw HSL channel values) live in tokens/base.json; the brand primary mapping lives in tokens/semantic.json, where it aliases one of those scales. Re-point it (or edit the underlying scale in base.json), then run pnpm run tokens:build:

json { “semantic”: { “primary”: { “500”: { “value”: “{color.violet.500}” } } } }

Content

Add content in src/content/:

• Blog posts: src/content/blog/
• Projects: src/content/projects/

🚀 Deployment

Cloudflare Pages

1. Fork this repository
2. Create new Cloudflare Pages project
3. Set build command: pnpm build

Architecture Overview

System Design

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

Technology Stack

• Framework: Astro (version pinned in package.json)
• Styling: Tailwind CSS with design tokens (version pinned in package.json)
• 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

Atomic Design Structure

atoms/ Button.astro # Single-purpose components Badge.astro Icon.astro

molecules/ Card.astro # Combinations of atoms ContactForm.astro Dialog.astro

structural/ Header.astro # Page-level structure Section.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

Performance Strategy

Build-Time Optimization

• Static generation by default
• Image optimization pipeline
• Critical CSS extraction
• Tree shaking

Runtime Optimization

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

Security Architecture

Headers Configuration

Environment Variables

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

Deployment Architecture

CI/CD Pipeline

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

Environments

3. Component Documentation

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’

Get Started

Learn More Call to Action

Props:

• variant: ‘primary’ | ‘secondary’ | ‘ghost’
• size: ‘sm’ | ‘md’ | ‘lg’
• href?: string (renders as link if provided)
• disabled?: boolean
• class?: string (additional classes)

Atom: Badge

Small labeling component for tags and statuses.

astro Active Beta

Props:

• variant: ‘primary’ | ‘secondary’ | ‘neutral’
• size: ‘xs’ | ‘sm’ | ‘md’
• class?: string (additional classes)

FormField (a component you build)

The template has no shipped FormField — its contact form is the molecules/ContactForm.astro molecule. Document form components you build like this:

Accessible form field with label and error handling.

astro

Props:

• label: string
• name: string
• type: HTML input type
• required?: boolean
• error?: string
• helpText?: string

Section Components

Hero (a component you build)

The template composes sections in pages from structural/Section.astro and structural/Container.astro rather than shipping a Hero — this documents the Hero pattern built in Phase 6.

Full-width hero section with optional background pattern.

astro <Hero title=“Welcome to My Site” subtitle=“Building amazing web experiences” primaryCTA={{ text: “Get Started”, href: “/start” }} secondaryCTA={{ text: “Learn More”, href: “/about” }} />

Props:

• title: string
• subtitle?: string
• primaryCTA?: { text: string, href: string }
• secondaryCTA?: { text: string, href: string }
• backgroundPattern?: boolean

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

4. API Documentation (If Applicable)
