1. Create a new .mdx file in app/posts/_articles/
2. Add metadata at the top:

export const metadata = {
  title: 'Your Post Title',
  description: 'A brief description',
  date: '2025.01.01',
  tags: ['Tag1', 'Tag2'],

  // Optional: show a table of contents sidebar (default open)
  toc: true,

  // Optional: OG/social card image (hosted on Cloudflare R2 or any public URL)
  image: 'https://r2.linghao.io/blog-assets/your-image.png',
  imageWidth: 1200,
  imageHeight: 630,

  // Optional: multilingual linking (see Multilingual Support below)
  language: 'en',
  translationId: 'shared-slug',
  canonical: true,
}

Your content here...

3. The post will automatically:
   • Appear in the posts index
   • Be included in RSS feed
   • Be filterable by tags
   • Get a URL like /posts/your-post-title
   • Have anchor links on all headings (#heading-slug)

Any post with two or more headings gets a toggleable TOC sidebar. A small icon button appears on the right side of the viewport; clicking it opens a panel listing all headings (h2–h4) with hierarchical numbering and active-heading highlighting as you scroll.

By default the sidebar is closed. Set toc: true in the article metadata to have it open automatically — useful for long reference posts.

Articles sharing a translationId are grouped as translations of each other. The article page shows a language switcher between them. Only the canonical: true version appears in index pages and tag pages.

export const metadata = {
  title: 'My Post',
  language: 'en',
  translationId: 'my-post',
  canonical: true,
}

• Posts (app/posts/_articles/) - Blog posts and reading notes
• Misc (app/misc/_articles/) - Miscellaneous content

Legacy /notes/* URLs are still supported for backward compatibility, but new content should be added under posts.

The public resume is available at /resume. Its content source is app/resume/source.ts, and the rendered HTML page is app/resume/page.tsx. Update content in source.ts; only edit page.tsx for layout/styling changes. See docs/resume.md for the full update workflow.

The gallery feature displays a collection of photography. Photos are managed in app/gallery/data.ts.

To add a new photo:

1. Upload the image to a hosting service (e.g., Cloudflare R2).
2. Add a new object to the photos array in app/gallery/data.ts:

{
  id: 'unique-id',
  src: 'https://your-image-url.jpg',
  alt: 'Description for accessibility',
  caption: 'Optional caption text',
  metadata: {
    'Location': 'Kyoto, Japan',
    'Date': '2024-10-28',
    'Camera': 'Sony α7C II',
  }
}

MDX files can use React components:

<Card
  image="https://example.com/image.jpg"
  title="Card Title"
  desc="Description"
  link="https://example.com"
/>

<BlockSideTitle title="Side note text">
  Main content here
</BlockSideTitle>

The blog uses the "rurikon" color palette defined in app/globals.css, mapped to Flexoki values. Customize colors by modifying the @theme section. See docs/visual-style.md for the full palette reference.

Fonts are loaded locally via next/font/local in app/layout.tsx and exposed as CSS variables:

• --sans: Inter Variable (body text, headings, UI elements — used everywhere)
• --serif: Lora Italic Variable (navigation elements via global nav {} rule)
• --mono: Iosevka Fixed Curly (code blocks and inline code)

Edit components/navbar.tsx to modify navigation links.

# Deploy to preview
npm run deploy

# Deploy to production
npm run deploy:prod

See DEPLOYMENT.md for detailed setup instructions.

Add tags to any article's metadata:

export const metadata = {
  title: 'My Post',
  tags: ['JavaScript', 'React', 'Web Development'],
}

• Browse all tags: /tags/all
• Filter by tags: /tags/all?tag=JavaScript
• Click tags on articles to filter

The RSS feed is automatically generated on every build:

• Feed URL: https://linghao.io/feed.xml
• Includes: All posts and misc articles
• Updates: Automatic on deployment
• Manual generation: npm run rss
