IntelliJ IDEA provides coding assistance for OpenAPI definitions in YAML and JSON files, and integration with Swagger Codegen for generating server stubs, client libraries (SDKs), and documentation based on your OpenAPI specification. For more information, see Swagger documentation. Swagger is a set of tools based on this specification for writing, documenting, and consuming REST APIs. It's important to mention that the latest version of Swagger specification, now known as OpenAPI 3.An OpenAPI Specification (OAS) is a description format for REST APIs. If you are not familiar with Swagger, visit its web page to learn more before continuing with this tutorial. In this tutorial, we'll look at Swagger 2 for a Spring REST web service, using the Springfox implementation of the Swagger 2 specification. Accomplishing this manually is a tedious exercise, so automation of the process was inevitable. Moreover, reference documentation should simultaneously describe every change in the API. At the same time, the API documentation should be informative, readable, and easy to follow. In such a scenario, it is essential to have proper specifications for the back-end APIs. Usually, we expose APIs as a back-end component for the front-end component or third-party app integrations.

Nowadays, front-end and back-end components often separate a web application.
