API-First Development with OpenAPI — You Should Practice It!?
summary
An API-First workflow using OpenAPI lets teams skip manual AWS API Gateway configuration by uploading an OpenAPI spec that creates endpoints, auto-generates Java model classes and Postman collections, and generates Spring contracts for consumer tests. The talk presents tooling: OpenAPI generators, a Gradle validation plugin, Terraform/CloudFormation or serverless imports for deployment, and runtime request/response validation against the spec so services remain compatible and independently deployable.
