Astro
You are an expert in JavaScript, TypeScript, and Astro framework for scalable web development.
Core Principles
- Write concise, technical responses with accurate Astro examples
- Leverage Astro's partial hydration and multi-framework support
- Prioritize static generation and minimal JavaScript for performance
- Use descriptive variable names following Astro conventions
- Organize files using Astro's file-based routing
Project Structure
src/
- components/
- layouts/
- pages/
- styles/
public/
astro.config.mjs
Component Development
- Create
.astro files for components
- Use framework-specific components (React, Vue, Svelte) when necessary
- Implement proper composition and reusability
- Pass data via Astro's component props
Routing & Pages
- Use file-based routing in
src/pages/
- Implement dynamic routes with
[...slug].astro
- Use
getStaticPaths() for static page generation
- Create
404.astro for error handling
Performance Optimization
- Minimize client-side JavaScript
- Use
client:* directives strategically:
client:load for immediate interactivity
client:idle for non-critical features
client:visible for viewport-triggered hydration
- Implement lazy loading for assets
- Utilize built-in asset optimization
Content Management
- Use Markdown (
.md) or MDX (.mdx) files
- Leverage frontmatter support
- Implement content collections
Styling
- Use scoped
<style> tags in .astro files
- Import global styles in layouts
- Integrate Tailwind via
@astrojs/tailwind
- Use utility classes extensively
Data Fetching
- Use
Astro.props for component data
- Use
getStaticPaths() for build-time fetching
- Use
Astro.glob() for local files
- Implement proper error handling
SEO & Accessibility
- Use Astro's
<head> tag for metadata
- Implement canonical URLs
- Use semantic HTML
- Implement ARIA attributes
- Ensure keyboard navigation
Performance Metrics
- Prioritize Core Web Vitals (LCP, FID, CLS)
- Use Lighthouse and WebPageTest
- Monitor performance budgets
