This repository is a Next.js SEO library that provides React components for generating JSON-LD structured data (Schema.org) to enhance search engine optimization. The library offers over 50 specialized components for various Schema.org types (Article, Recipe, Product, Event, etc.) and a core JsonLdScript component for rendering JSON-LD tags. It includes utility processors for normalizing flexible input data into Schema.org-compliant formats and emphasizes security through XSS prevention in JSON-LD stringification. The architecture follows a modular component pattern with strong TypeScript typing, comprehensive testing (unit and E2E), and support for both Pages Router and App Router in Next.js. The library is actively maintained with recent updates, a changeset-based versioning system, and extensive documentation.
