The user interface is called Swagger UI and the code generator is called Swagger Codegen. One advantage of Swagger is its comprehensive extension mode, which is supported by a core library known as the Swagger Core. Via the user interface, developers can not only manage documentation, but also use Swagger to run ad-hoc tests. Put simply, Swagger is language-neutral and machine-readable. The user interface (UI), which provides an easy way of creating the API documentation, is based on HTML and JavaScript.

They can see the interfaces used and instantly create the documentation.ĭepending on the field of application, the core element of Swagger is either a JSON or a YAML file. Using Swagger, even teams who were not directly involved in the development process can set up APIs. It is an open description format that helps provide an overview of the various capabilities of APIs. This is where the OpenAPI specification Swagger comes in. However, to be able to use these interfaces, you have to know about their structure and functions. Nowadays APIs play a key role in connecting software in almost every kind of system. APIs connect applications with one another and with data sources and other systems. At best, this becomes apparent when a team other than the development team try to carry out maintenance and make improvements – and this scenario is the rule rather than the exception.ĭocumenting APIs, or Application Programming Interfaces, is even more important. In development projects, creating documentation is very time-consuming, and outsiders often do not realize how important it is for maintaining and further developing systems.
