# CLAUDE.md
nicholai.work - claude guide
===
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
this is an astro-based portfolio and blog site deployed on cloudflare pages. content-driven architecture with three main layers: content collections, components, and pages/layouts.
## Development Commands
development commands
---

architecture overview

# Image conversion to AVIF format
pnpm run convert:avif:all # Convert all images

content layer (src/content/**)
# Cloudflare types generation
pnpm cf-typegen # Generate Cloudflare types for TypeScript
```
content is managed via astro's content collections API with schema validation in src/content.config.ts:
## High-Level Architecture
blog/ - blog posts as MDX files
- schema: title, description, pubDate, updatedDate, heroImage, featured, category, tags
- sorted by pubDate (newest first)
- featured post displayed on homepage and blog index
This is an Astro-based portfolio and blog site deployed on Cloudflare Pages. The architecture follows a content-driven approach with three distinct layers:
sections/ - homepage section content
- hero, experience, skills, featured-project
- each has custom schema for its needs
- experience: systemId, status, dates, company, role, tags, description, achievements, link
- skills: id, domain, tools, proficiency
### 1. Content Layer (`src/content/**`)
Content is managed via Astro's Content Collections API with schema validation defined in `src/content.config.ts`:
pages/ - page-specific content
- contact form configuration, labels, social links, subject options
- **`blog/`** - Blog posts as MDX files
- Schema: title, description, pubDate, updatedDate (optional), heroImage (optional), featured (boolean), category, tags
- Posts are sorted by pubDate (newest first)
component layer
- **`sections/`** - Homepage section content (hero, experience, skills, featured-project)
- Each section has a custom schema for its specific data needs
- Experience entries include systemId, status, dates, company, role, tags, description, achievements, link
- Skills entries include id, domain, tools, proficiency
organized by purpose:
- core UI: BlogCard, FormattedDate, Navigation, Footer, GridOverlay
- blog: BlogFilters, ReadingProgress, TableOfContents, PostNavigation, RelatedPosts
- sections: Hero, Experience, Skills, FeaturedProject
- **`pages/`** - Page-specific content (contact form configuration)
- Includes form labels, social links, subject options
page & layout layer
### 2. Component Layer
Components are organized by purpose:
- BaseLayout - shared structure for all pages
- BlogPost - blog post template with sidebar, navigation, related posts
- src/pages/ - static routes + dynamic blog routes via [...slug].astro
- **Core UI**: `BlogCard`, `FormattedDate`, `Navigation`, `Footer`, `GridOverlay`
- **Blog-specific**: `BlogFilters`, `ReadingProgress`, `TableOfContents`, `PostNavigation`, `RelatedPosts`
- **Section components**: `Hero`, `Experience`, `Skills`, `FeaturedProject`
design system
---
### 3. Page & Layout Layer
- **Layouts**: `BaseLayout` (shared structure), `BlogPost` (blog template)
- **Routes**: Static routes in `src/pages/` with dynamic blog routes via `[...slug].astro`
design.json documents the evolution from industrial/technical to modern/clean design language.
## Data Flow Patterns
key principle: industrial styling reserved for hero, experience, and featured project sections only. everything else (blog, navigation, new sections) uses modern design.
### Blog Index (`src/pages/blog/index.astro`)
1. Fetches all posts via `getCollection('blog')`
2. Sorts by pubDate (newest first)
3. Identifies featured post (first with `featured: true` or fallback to latest)
4. Renders featured hero + filterable grid of all posts
5. Extracts unique categories for filter UI
modern design (default for new work):
- rounded corners (rounded-lg, rounded-full, rounded-xl)
- clean typography (normal case, no excessive uppercase)
- simple badges with bg-brand-accent/10
- clean metadata format: "date · read time"
- hashtag format for tags (#tag)
- no font-mono or tracking-widest on everything
- faster transitions (300ms)
### Individual Blog Posts (`src/pages/blog/[...slug].astro`)
1. Uses `getStaticPaths()` to generate all blog post routes
2. For each post, calculates:
- Previous/next posts (by date)
- Related posts (matching category or shared tags, limited to 3)
- Reading time (based on word count, 200 wpm)
3. Passes everything to `BlogPost` layout which handles headings, navigation, related posts
industrial design (hero/experience/featured only):
- sharp corners
- uppercase tracking-tighter titles
- font-mono system labels
- pulsing dots, accent strips
- technical aesthetic
### Content Collections
All content follows the schema validation pattern:
```
MDX file → src/content.config.ts schema → getCollection() → Component props
```
when building new features, default to modern design unless explicitly working on hero/experience/featured sections.
## Key Technical Patterns
data flow patterns
---
### Image Handling
- Assets in `src/assets/` are processed by Astro (use relative paths in frontmatter)
- Static files in `public/media/` are served as-is (use absolute paths like `/media/file.mp4`)
- AVIF conversion utility available for optimization
homepage (src/pages/index.astro):
- fetches hero, experience, skills, featured-project from content collections
- queries 3 most recent blog posts for latest blogs section
- displays in order: hero → experience → featured project → skills → latest blogs
### UI Development
- **Always review UI changes in the browser** - Check if the dev server is already running before starting it with `pnpm dev`, then visually verify components, animations, and layouts before considering work complete
blog index (src/pages/blog/index.astro):
- fetches all posts via getCollection('blog')
- sorts by pubDate newest first
- identifies featured post (first with featured: true or fallback to latest)
- renders featured hero + filterable grid of all posts
- extracts unique categories for filter UI
## Design Specification
individual blog posts (src/pages/blog/[...slug].astro):
- uses getStaticPaths() to generate routes
- calculates previous/next posts by date
- finds related posts (matching category or shared tags, limited to 3)
- calculates reading time (200 wpm)
- passes to BlogPost layout
`dev/design.json` contains V7 Industrial Dark Mode system specification (not yet implemented):
- Dark mode native with `#0B0D11` primary background
- Orange/yellow accent `#FFB84C` for CTAs
- Brutalist/industrial aesthetic with visible grid structure
- Heavy typography emphasis

### Deployment
- Cloudflare Pages adapter configured in `astro.config.mjs`
- Image service set to "compile" mode
- Platform proxy enabled for development
image handling:
- assets in src/assets/ processed by astro (use relative paths in frontmatter)
- static files in public/media/ served as-is (use absolute paths like /media/file.mp4)
- AVIF conversion utility available
## Blog Post Creation Workflow
content collections pattern:
MDX file → src/content.config.ts schema → getCollection() → component props
1. Create `.mdx` file in `src/content/blog/` (filename becomes URL slug)
2. Add required frontmatter: title, description, pubDate
3. Optionally add: heroImage, featured, category, tags
4. Write content using Markdown/MDX with embedded JSX/HTML
5. Images can reference `src/assets/` (relative) or `public/media/` (absolute)
UI development:
- ALWAYS review UI changes in the browser
- check if dev server is running before starting it
- visually verify components, animations, layouts before considering work complete
## Utility Scripts
deployment:
- cloudflare pages adapter configured in astro.config.mjs
- image service set to "compile" mode
- platform proxy enabled for development
- production domain: nicholai.work
