It is language-agnostic and is extensible into new technologies and protocols beyond HTTP. Swagger 2 is an open source project used to describe and document RESTful APIs. In this post, I’ll cover how to use Swagger 2 to generate REST API documentation for a Spring Boot 2.0 project. For best practices on documentation, I suggest going through this presentation by Andy Wikinson. I won’t be covering it here in this post. However, the best practices on how you document your API, its structure, what to include and what not, are altogether a different subject. Thus your API documentation becomes more critical.ĪPI documentation should be structured so that it’s informative, succinct, and easy to read. However, with RESTFul web services, there is no WSDL. This gave API developers a XML based contract, which defined the API. In SOAP based web services, you had a WSDL to work with.
Your clients will need to know how to interact with your API. You now have clients which will now be using your API. The Spring Boot makes developing RESTful services ridiculously easy, and using Swagger makes documenting your RESTful services much easier.īuilding a back-end API layer introduces a whole new area of challenges that goes beyond implementing just endpoints.
