I gave an Introduction to OpenAPI presentation at a tech meetup in Coeur d’Alene on August 11, 2022.
The talk contains an overview of what the OpenAPI spec enables, how it can help teams and organizations by optimizing the process of defining and sharing knowledge about how an API works. And then I provided hands-on demo of how to write an OpenAPI spec and generate a server and client in TypeScript.
