What it is

Astro is a modern static site builder and web framework that generates lightweight, fast websites by default. It allows developers to use their preferred UI framework (React, Vue, Svelte, etc.) while shipping minimal JavaScript—the core innovation is "islands of interactivity" where only interactive components are sent to the browser as JavaScript. The framework is built around content-driven sites with built-in asset optimization, font handling, and action-based server communication. Monorepo with packages/astro/ as the core engine, packages/integrations/ housing framework adapters (@astrojs/react, @astrojs/preact, etc.), and packages/create-astro for the CLI scaffolder. Within…

Read these in order:

• packages/astro/src/assets/utils/vendor/image-size/types/index.ts — Foundation: imported by 1, no internal dependencies of its own.
• packages/astro/src/assets/utils/vendor/image-size/detector.ts — Built on the foundation; imported by 0 downstream files.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Verify the repository has a package.json or pnpm-workspace.yaml for monorepo setup before running commands. Based on the directory structure and package exports, run: `git clone https://github.com/withastro/astro && cd…

Daily commands:

Evidence is insufficient in the provided data. Check packages/astro/ and the repository root for package.json scripts (likely dev, build, test). The README references npm create astro@latest for user installation,…

Key cautions & unknowns

• Scorecard: default branch unprotected (0/10)
• 1 moderate-severity advisory on direct dependencies
• The monorepo uses workspace:* dependencies, meaning local packages must be installed as a unit—installing only packages/astro/ in isolation will fail. Font optimization uses capsize metrics resolution, which requires…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
