API First development, should you practise it?

Of course. In this lightning talk (shorttalk) I’ll show you how OpenAPI can make your life easier in a serverless world:
– creating the contract with your consumers is the first thing that you do
– you can automatically create your API from this OpenAPI definitions (eg. skip the whole configuration of your API Gateway on AWS by using OpenAPI)
– you’ll have a beautiful visual overview of your API
– generate your class definitions based on this OpenAPI definitions
– validate incoming and outgoing requests with the OpenAPI definition

Did you notice that I just gave you five advantages of using OpenAPI?
It’s only the beginning. And that’s why you should practice API First development with OpenAPI.
