Structured data is one of those things every developer knows they *should* implement, but few actually do. Why? Because writing JSON-LD by hand is error-prone, tedious, and easy to get wrong. What if you could generate type-safe structured data with autocomplete, validation, and zero runtime overhead? ## The Problem with JSON-LD Here's what typical JSON-LD looks like: ```json { "@context": "https://schema.org", "@type": "Article", "headline": "My Blog Post", "author": { "@type": "Person", "name": "Jane Doe" }, "datePublished": "2026-02-10" } ``` Looks simple, right? But try maintaining this across dozens of pages: - Did you forget the `@context`? - Is `datePublished` in the right format? - Did you typo `Article` as `Aticle`? - Is this even valid according to schema.org? **These mistakes cost you search rankings and AI visibility.** ## Enter Schema Sentry [Schema Sentry](https://github.com/arindamdawn/schema-sentry) is a type-safe library for generating JSON-LD structured data. It gives you: ✅ **Full TypeScript autocomplete** - No more guessing field names ✅ **Compile-time validation** - Catch errors before they reach production ✅ **Zero runtime overhead** - Everything happens at build time ✅ **Works with both Pages Router and App Router** - Your choice of Next.js patterns ✅ **CI/CD validation** - Automated checks in your pipeline ## Quick Example Instead of hand-writing JSON: ```tsx // ❌ Error-prone manual JSON
