Hvad er ASTRO-filformatet?
En .astro-fil er en komponent, der bruges af Astro, et open-source webframework til indholdsfokuserede websteder som blogs, dokumentation og marketingsider. Fred K. Schott skabte Astro i 2021, og det nåede en stabil 1.0 i august 2022. Projektet vedligeholdes nu under MIT-licensen, efter at Cloudflare opkøbte Astro Technology Company i januar 2026.
Hver fil har to dele opdelt af en --- kode-adskiller. Over adskilleren sidder komponentscriptet, eller frontmatter, skrevet i JavaScript eller TypeScript. Det kører på build-tidspunktet for at importere andre komponenter, hente data og erklære variabler. Under adskilleren er skabelonen, en HTML-lignende blok, der accepterer {}-udtryk, <slot />-pladsholdere og afgrænsede <style>- og <script>-tags. Syntaksen er en overbygning af .html og minder meget om JSX, selvom den bruger standard kebab-case-attributter.
Astro renderer komponenter til HTML på forhånd og sender som standard intet JavaScript til klientsiden. Interaktive dele tilføjes selektivt gennem ø-arkitekturen (islands architecture) ved hjælp af client:*-direktiver på framework-komponenter.
Sikkerhed og tryghed
RISIKO: LOWAn .astro file is human-readable source text and cannot run on its own by double-clicking. It only executes when compiled by the Astro toolchain during a build. As with any project source, its frontmatter can contain JavaScript, so review files from untrusted repositories before running npm install or a build, since build scripts and dependencies (not the .astro file itself) are the real risk.
Formatdetaljer
kort fortalt- ASTRO-VISION LifeSign / horoscope data - Some astrology software has used .astro for chart or profile data files. Unrelated to the web framework.
- Generic astronomy/astrology data exports - Occasionally seen as an ad hoc extension for star-chart or ephemeris data in niche tools.

dyb specifikation| Encoding | UTF-8 plain text |
| Byte order | Not applicable (text) |
| Container | None; single source file |
| Typical size | A few hundred bytes to tens of kilobytes |
| Structure | Two sections separated by a --- code fence: an optional component script (frontmatter) written in JavaScript/TypeScript that runs at build time or on the server, followed by a component template made of HTML-like markup with {} expressions, directives, <slot />, <style> and <script> tags. |
| Integrity | None built in |
| Platforms | Windows, macOS, Linux |
| Notes | Astro components render to HTML ahead of time and ship no client-side JavaScript runtime by default. Interactive framework components can be hydrated selectively using client:* directives (the islands architecture). The Astro compiler parses .astro files and outputs HTML plus any scoped CSS and hydration code. |
| Syntax Basis | Superset of HTML, close to JSX but using standard kebab-case HTML attributes |
| Runtime | Server/build-time rendering; no default client runtime |
| Language Support | JavaScript and TypeScript in the frontmatter, including top-level await |
