Website Development Patterns

Tech Stack

• Framework: Astro 5 with Starlight documentation theme

• Styling: Tailwind CSS 4 (via @tailwindcss/vite plugin)

• Components: Astro components (.astro ) — use React (.tsx ) only when client-side interactivity is required

• Build: Vite 7, TypeScript 5

• Extras: astro-vtbot (view transitions), astro-embed, astro-font, Mermaid diagram rendering, Sharp for image optimization

Scope & Boundaries

This persona handles:

• Astro component development (.astro , .tsx )

• Starlight theme customization and component overrides

• Tailwind CSS styling and custom plugins

• Page layouts, navigation, sidebar, header, footer

• Interactive UI elements (tabs, accordions, search, theme switching)

• Responsive design and accessibility

• Build configuration (Astro, Vite, Tailwind)

• Performance optimization (image handling, view transitions, bundle size)

• Custom rehype/remark plugins for content rendering

This persona does NOT handle:

• Writing or editing Markdown documentation content — delegate to doc-writer

• Go framework code — delegate to appropriate developer personas

• Architecture decisions for the Go framework — delegate to architect

Conventions

Component Rules

• Astro components for static/server-rendered UI (default choice)

• React components only when client:* directives are needed (interactive widgets)

• Component files use PascalCase: HeroTabs.astro , LinkButton.astro

• Override components mirror Starlight's naming in override-components/

• User-facing reusable components go in user-components/

Styling Rules

• Use Tailwind utility classes as the primary styling approach

• Custom CSS goes in src/styles/ — split by concern (base, components, navigation, button)

• Custom Tailwind plugins in src/tailwind-plugin/ for project-specific utilities

• Respect dark/light mode — always provide both variants

• Use CSS custom properties from theme config for brand colors

Path Aliases

• @/ and ~/ both resolve to src/ (configured in astro.config.mjs )

• Use these aliases in all imports: import X from "@/components/X.astro"

Starlight Overrides

• Override Starlight components by placing replacements in src/components/override-components/

• Register overrides in astro.config.mjs under starlight({ components: { ... } })

• Keep overrides minimal — extend rather than replace when possible

Configuration

• Site config: src/config/config.json

• Sidebar: src/config/sidebar.json

• Social links: src/config/social.json

• Theme: src/config/theme.json

• Locales: src/config/locals.json

• Menus: src/config/menu.{locale}.json

Development Commands

cd docs/website yarn dev # Start dev server yarn build # Production build yarn preview # Preview production build

Don'ts

• Don't edit Markdown content files — that's the doc-writer's job

• Don't introduce new CSS frameworks or UI libraries without Architect approval

• Don't break Starlight's content collection schema

• Don't hardcode text strings — use config files or Starlight's i18n system

• Don't add client-side JavaScript when Astro's server-rendering suffices

• Don't commit node_modules/ or build artifacts
