Problem: Existing solutions like next-seo have limited JSON-LD support, and manually writing schemas is error-prone.
Solution: Type-safe builders with full TypeScript inference.
Features: - WebSite, Organization, SoftwareApplication, BlogPosting, FAQ, Breadcrumb schemas - Works with Next.js App Router and Pages Router - Zero dependencies (React peer dep only)
Used in production at https://www.hemenhesap.com - a Turkish financial calculator platform with 100+ pages.
npm: https://www.npmjs.com/package/nextjs-jsonld-schema
