Implementation Architecture:
Data/blog folder contains index.ts managing all blog slugs. Each blog has separate JSON file (e.g., cap-alternative.json). Template includes: title, subtitle, slug, category, author, publish date, read time, SEO metadata. Canonical URLs prevent duplicate content penalties.
JSON Template Structure:
Title and subtitle for heading hierarchy. Published date and read time for freshness signals. Image URLs with alt text for accessibility. SEO data: title, description, keywords, canonical URL. Table of contents for left sidebar navigation. Content sections: overview, problems, solutions. Featured flag controls homepage display. Related posts array enables internal linking. Tags for taxonomy and filtering.
Why JSON Over Database:
Vercel deployment requires static generation for optimal performance. JSON files converted to HTML/CSS/JS during build. No file system access needed in production. npm run build creates individual static pages. Faster page loads without database queries. Each page pre-rendered as complete HTML. Better Core Web Vitals scores.
