In this short talk, Johannes explains how you can easily generate Javascript client code SDKs to use for calling your REST API using Swagger.
Johannes walks us through the steps you need to take starting with a REST-API (example Spring Boot) to the Swagger-specification, then calling Swagger-Codegen to generate the client SDK.
The results are: the generated Javascript model, code completion for the model classes (including JSDoc support) in Javascript and in HTML and code completion for the REST API operations.
