Contract-Driven API Development with OpenAPI Specification

Originally aired:

About the Session

We've all seen APIs that are hard to work with: incomplete and at places inaccurate documentation, non-standard design choices, inconsistent patterns across endpoints. Such APIs are often poorly planned in the first place, and then continue evolving in response to ad hoc customer needs with little strategy involved, becoming increasingly difficult to both maintain and consume. The Open API Specification (OAS), conceived just a few years ago, quickly became a widely adopted standard for describing RESTful APIs and created a powerful ecosystem of API development tools around it.

This talk proposes a mature, design-first approach to delivering RESTful APIs that makes development teams on both sides more productive. The approach relies on OAS as a contract to avoid breaking changes, enforce always up to date documentation, support design standardization, enable mocking and code generation.
