Path Aliases

Use ~/ to import from src/:

import Image from '~/components/common/Image.astro';
import { SITE } from 'astrowind:config';

Configuration System

Site config lives in src/config.yaml and is loaded as a Vite virtual module astrowind:config by the custom integration in vendor/integration/. Exports: SITE, I18N, METADATA, APP_BLOG, UI, ANALYTICS.

Tailwind CSS v4

Configuration is CSS-first in src/assets/styles/tailwind.css:

• Theme tokens: @theme { --color-primary: var(--aw-color-primary); ... }
• Custom utilities: @utility bg-page { ... }
• Dark mode: Class-based via @variant dark (&:where(.dark, .dark *))
• Plugins: @plugin "@tailwindcss/typography"
• Custom variant: @custom-variant intersect (&:not([no-intersect]))

CSS variables for colors/fonts are defined in src/components/CustomStyles.astro with light/dark theme variants.

The Vite plugin @tailwindcss/vite is configured in astro.config.ts (not as an Astro integration).

Class Merging

Components use twMerge from tailwind-merge v3 for conditional class composition.

Content Collections

Defined in src/content.config.ts using the Astro v6 Content Layer API with glob() loader. Posts are in src/data/post/ as .md or .mdx files.

Post frontmatter: title (required), publishDate, updateDate, draft, excerpt, image, category, tags, author, metadata.

Component Patterns

• Props extend interfaces from ~/types
• Use class:list for conditional classes
• Use twMerge() when accepting className overrides
• Use named slots for layout composition
• Widget components accept standardized props (see ~/types)

Image Handling

src/components/common/Image.astro supports:

• Local images via astro:assets (optimized by Sharp)
• Remote images via Unpic CDN
• Allowed domains (for providers Unpic can't detect, processed by Sharp): cdn.pixabay.com

Hero images use loading="eager" and fetchpriority="high".

Verification Checklist

After changes, always verify:

1. npm run build succeeds
2. npm run check passes (astro check + ESLint + Prettier)
3. Visual check in browser: homepage, blog, dark mode, mobile menu

Skills

• j-space: MANDATORY for audits, consistency checks, or multi-step tasks across site/ and cte/. Load before starting.
• Trigger keywords: audit, verify, check consistency, multi-step, long-running, complex, debug across files → always load J-Space first.
