Some developers implement APIs, thinking about things like specifications and documentation only after they’re released. Dave Forgac and Ian Zelikman demonstrate how to use a contract-first approach to API development using the OpenAPI Specification (formerly called Swagger) and other open source tools. Dave and Ian walk you through defining a simple API specification, using it to generate documentation, a mock server, and stub code, and implementing a working API based on the specification.
Dave Forgac is a senior software engineer at American Greetings in Cleveland, where he is responsible for API development, application deployment, and developer happiness engineering. Dave has been a FOSS enthusiast ever since installing Linux for the first time in the late ’90’s. He loves building communities and is an organizer of PyOhio, ClePy, and the Cleveland API Meetup.
Ian Zelikman is a software engineer at IBM Watson Health, where he works with big data and healthcare. Ian has worked with web technologies for over 10 years, ever since his first job developing applications for weather forecasting and analysis.
