How We Use Frontmatter

Frontmatter gives us page-level controls without changing TypeScript config for every article.

Layout flags

Two useful flags:

• toc: false to hide the table of contents
• wideContent: true to expand content width when TOC is hidden

SEO flags

You can override:

• title, description, canonical
• keywords, robots
• Open Graph and Twitter fields

Origin link for reposted articles

For articles that were published first on another platform (for example Medium), we add:

• origin with the external URL
• originLabel with custom text (optional)
