To add Swagger to your embedded Jetty Server, you must do 3 things: In the Swagger Core setup, the current official recommendations involve an Application class, or a web.xml, neither of which are used in an embedded Jetty server setup. Make sure you add all dependencies to your pom.xml. I am using Swagger 1.5, Maven 3.3.3, Jersey 1.8, and Jetty 7.3.

In this gist, we'll go through how to setup Swagger for this setup. (See here for how to setup an embedded Jetty server). There are generators for all common programming languages, and the templates can be customized and expanded.In setting up a Jetty server with Jersey servlets, you may choose to use an embedded Jetty server setup.

The code is then generated using Swagger. In a Design First approach, the first step is to prepare the description.
As mentioned above, client-side and server-side development is often carried out by different teams. The alternative approach is Design First. From this, Swagger can directly derive documentation that is independent of the programming language used and can be read both by humans and machines. In the Code First approach, the program code is the agreed starting point. The starting point of every API development is either the program code (“Code First”) or the interface description (“Design First”). The reason this works so well is because Swagger puts the REST API documentation directly into the code. It evolves with the system and all changes are automatically documented. Swagger is currently the best way of documenting REST APIs because it can map almost all web services and required information. This is especially true for public APIs – they would be useless to the community if they had no documentation. Without this, developers cannot use the interfaces. When developing an API, it’s essential to have well-organized, understandable documentation. This combination of perfect documentation and the ability to generate direct API requests is what makes Swagger so valuable.
This is especially useful when sending direct test requests from a browser. In the Swagger UI, everything can be displayed both in text form and graphically. Data types are dealt with in a separate section. Once everything has been categorized, the content is presented: paths, operators, and parameters and their descriptions are prepared. You can think of the structure like a complex index card system. After this it gives the MediaType for the entire API. Swagger also separates out the host, the path, and URL schemes and specifies each of these. The documentation file starts with the specification version number, and then gives the general information about the API, clearly organized under the “info” category. Swagger documents each interface with all the necessary information. There are code generators for almost every programming language. However, Swagger’s greatest strength – as with many open-source solutions – comes from its extensive ecosystem on GitHub.

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.
