OpenAPI 3.0 & Swagger: Writing Clean API Specifications and Documentation
Master OpenAPI 3.0 (OAS) and Swagger. Generate type-safe SDKs, automated mock servers, and interactive documentation from single YAML specifications.
The OpenAPI Specification (formerly Swagger) is the universal vendor-neutral standard for describing HTTP APIs. By maintaining an openapi.yaml file, engineering teams can automatically generate client SDKs in 30 languages, interactive API explorers, and regression test suites.
