Implementation Reference
- src/lib/markdown.ts:23-30 (handler)The actual implementation of the update_frontmatter logic, which parses existing frontmatter, merges it with new updates using gray-matter, and stringifies it back.
export function updateFrontmatter( content: string, updates: Record<string, unknown>, ): string { const parsed = matter(content); const merged = { ...parsed.data, ...updates }; return matter.stringify(parsed.content, merged); }
