+
+goa presents a novel approach to developing microservices in Go that starts with the design. It is
+comprised of three parts:
+
+* The goa design language is a Go DSL that makes it possible to describe the microservice APIs.
+* The goagen tool generates boilerplate code and documentation from the DSL.
+* The goa library is used by both the generated and user code to implement the microservice.
+
+This talk will go over the rationale for goa and explain the benefits of the approach. Writing the
+design in code has many advantages compared to the traditional descriptive approaches. goa presents
+benefits to both API developers and API reviewers.
