Design-first API Development using Swagger and Node
The document discusses design-first API development using Swagger and Node. It introduces APIs and their purpose. Design-first development means defining the API first using Swagger, then generating code from the specification. This ensures the API documentation and code stay in sync. The document outlines how Swagger-Node works by parsing a Swagger API definition to validate and route requests. It provides examples of how Apigee and customers like Burberry use this approach. Finally, it promotes API management tools from Apigee and demonstrates Swagger-Node.
