Learn how to implement self-service registration using Ory Kratos' headless architecture, utilizing JSON schemas and state-driven flows to decouple identity logic from your UI.
Integrate JSON Schema validation into a microservice with a stateless validator, caching, and robust observability. This architecture note covers requirements, minimal design, trust boundaries, operational checks, failure modes, and when to adjust the design.
Learn how to model polymorphic payloads with an OpenAPI discriminator, see a worked Pet/Cat/Dog example, and understand validation limits and common pitfalls.
Learn how Fastify uses Ajv and fast-json-stringify to move serialization overhead from runtime to startup, significantly increasing API throughput and security.
A practical guide to implementing Appwrite's server-side JSON schema validation: define initial schemas, verify validation behavior, evolve schemas without breaking existing documents, migrate legacy data when needed, and handle errors consistently across client platforms.
Use JSON Schema as the contract in Fastify for automatic request validation with AJV and pre-compiled response serialization with fast-json-stringify, scoped inside encapsulated plugins for modular, type-safe routes.
Learn how to eliminate redundancy in OpenAPI 3.0 specifications by using components/schemas and $ref pointers to create a single source of truth for your data models.
Replace scattered inline validation with a single declarative contract. A practical look at JSON Schema at the API boundary, with a working ajv example and the additionalProperties trade-off.
Ory Kratos uses one JSON Schema document as the source of truth for identity traits, driving both server-side validation and self-service form rendering. Here's how it works, with a worked example and the migration trap to avoid.
