OpenAPI is essentially a thin wrapper around JSON Schema. In production specs like Stripe's 100,000+ line specification, over 80% is pure JSON Schema. Want better OpenAPI specs? With this course, you will master the 80% that actually matters.
You probably don't know how dynamic references, `unevaluatedProperties`, the vocabulary system, or annotation extraction work. Most developers never get past trivial validation. This course covers the advanced mechanisms that separate experts from everyone else.
Learn to debug schemas with advanced trace inspection tools, write unit tests for them, enforce quality with linters, and deploy them to registries. This course teaches the software engineering practices and tools that professional teams use to write build production-grade schemas.
This curriculum is based on years of experience building JSON Schema tooling, delivering custom training, and consulting with Fortune 500 enterprises on API and schema design. Every module is packed with advance insights you won't find elsewhere.
