Astro: Built Fast by Default
summary
Astro 4.0 ships server-rendered HTML by default and only hydrates interactive parts using the Islands architecture and partial hydration, claiming about 90% reduction in shipped JavaScript and benchmarks up to 75% faster on complex pages. It supports React, Vue, Svelte, Solid via simple integrations (npx astro add react, tailwind), uses hydration directives like client:load / client:idle / client:visible, adds per-page view transitions with one line, auto-optimizes images (examples from megabytes down to kilobytes) and uses content collections plus Zod for type-safe markdown.
