详解Astro 5.0的核心理念和新特性，为什么它是博客、文档站和营销页面的最佳选择。
Deep dive into Astro 5.0's core philosophy and features — why it's the best choice for blogs, docs sites, and marketing pages.
Astro的核心理念Astro采用"群岛架构"（Islands Architecture）——页面默认是零JavaScript的静态HTML，只有需要交互的组件（"岛屿"）才加载JavaScript。这意味着90%的页面内容是纯HTML，加载速度远快于React/Next.js SPA。核心指标：Lighthouse性能分100分是常态。5.0新特性Content Layer API：统一管理来自文件系统、CMS和API的内容源。Server Islands：支持在静态页面中嵌入动态服务端渲染的组件（如个性化推荐、实时数据）。Actions API：类型安全的表单处理和服务端函数调用。改进的i18n路由：多语言站点的URL管理更加灵活。适用场景博客和技术文档站、企业营销官网、电商产品页面（结合Shopify等API）、SEO优先的内容站点。不适合：重交互的Web应用（如Figma这类工具、实时协作平台）。可以混合使用React/Vue/Svelte组件——Astro不要求你选边站。
Astro's Core PhilosophyAstro uses "Islands Architecture" — pages are zero-JavaScript static HTML by default, with only interactive components ("islands") loading JavaScript. This means 90% of page content is pure HTML, loading significantly faster than React/Next.js SPAs. Lighthouse performance scores of 100 are the norm.5.0 New FeaturesContent Layer API: unified management of content from file systems, CMSes, and APIs. Server Islands: embed dynamically server-rendered components (personalized recommendations, live data) in static pages. Actions API: type-safe form handling and server function calls. Improved i18n routing: more flexible URL management for multilingual sites.Use CasesBlogs and technical docs, enterprise marketing sites, e-commerce product pages (combined with Shopify APIs), SEO-first content sites. Not suitable for: heavy-interaction web apps (Figma-like tools, real-time collaboration platforms). Freely mix React/Vue/Svelte components — Astro doesn't force framework choices.
