Build Process

During pnpm build or pnpm dev, the build process:

Converts markdown files from /src/posts to HTML in /static/posts (you may need to create the /static/posts directory)
Generates metadata JSON files in /src/data for each post
Creates author, category and year indexes in /src/data

Alternatively, you can run the md2html script to generate the metadata and HTML files:

pnpm md2html
