Astro 6 checklist
Checked on 2026-05-03 against official Astro documentation and release notes.
Adopted
- Astro 6.2 with server output and explicit prerendering.
- Tailwind CSS 4 through the official Vite plugin path.
- Content Collections, MDX, RSS, sitemap, robots, and JSON-LD.
- Live Content Collections, Server Islands, Actions, Sessions, Middleware, and API routes.
- Fonts API, CSP API, prefetch, image defaults, SVG optimizer, and optional JSON logging.
- Node standalone adapter, Docker, GitHub Actions, and Dependabot groups.
- CSP is disabled in dev mode because Astro 6 CSP is not supported with the Vite dev server; production builds keep CSP enabled.
Deferred
Experimental route caching, queued rendering, and client-side view transitions are documented but not enabled by default because they depend on hosting, traffic behavior, and CSP requirements.
