Learn Swagger UI with online courses and programs

Learn how to develop and document APIs with Swagger UI. Boost your career in software development with courses delivered through edX.

What is Swagger UI?

Swagger UI is a tool that allows software developers to visualize and interact with Application Programming Interfaces (APIs).Footnote 1 As a software or API developer, documenting and testing code is an important but intensive step of the software development process. 

Swagger UI provides an interface for developers to test and debug APIs without additional software. It’s able to generate documentation for APIs in real-time, making it easier for developers to understand and use the APIs.Footnote 2 It also supports a wide variety of programming languages and frameworks, which makes it versatile for many applications.

 Swagger UI tutorial curriculum

A Swagger UI course can help you build the foundation for developing REST APIs. You can learn how to create, document, and test RESTful APIs.

To start off, a Swagger UI course might teach you how to:

  • Identify the basic components of Swagger UI, its features, and how it streamlines REST API development. 

  • Create a Swagger UI URL. 

  • Identify common Swagger UI URL connections like Swagger-UI-express, Springfox-Swagger-UI, and Swagger-UI-dist.

  • Visualize and test your API development code. 

As you progress through your course, some other important concepts you might study include:

  • How to create and document RESTful APIs.

  • How to define endpoints, methods, parameters, and responses.

  • How to use built-in testing tools to validate API responses.

  • How to build test cases.

If you’re curious about how to learn Swagger UI, you may want to consider taking an online course through edX. A boot camp can be a good option for hands-on, flexible, and fast-paced learning. If you want to elevate your leadership skills alongside your technical competencies, the executive education path may be best suited for you. For those who prefer a more traditional learning path, consider enrolling in a bachelor's degree program online or pursuing a master's degree. There are many different educational opportunities to fit different learners’ needs.

Understanding API documentation is an important skill for software development. When you learn Swagger UI, you can prepare for careers like:

  • Web and software developer: Web or software developers are responsible for creating, designing, building, and maintaining web applications, software programs, and other digital products.Footnote 3 They may use Swagger UI to design, test, and debug the APIs they build, as well as help them integrate APIs into other aspects of the development process.

  • Test engineer: Test engineers, also called quality-assurance engineers, are responsible for thoroughly testing software in development against many use cases for bugs and other errors.Footnote 4 Swagger UI may help test engineers streamline that process with the development of APIs.

  • Front-end developer: Front-end developers are responsible for building the user-facing part of a website or application.Footnote 5 They work with design teams and back-end developers to create the look, feel, and functionality of a website or application. Swagger UI may help front-end developers better understand APIs without needing involvement in their development.

  • Full-stack developer: Full-stack developers frequently work with APIs to connect the work they are doing on the back-end with the front-facing user interfaces of their software.Footnote 6 A tool like Swagger UI may help them document that development process to ensure a more seamless build.

Each of these roles will have different skills and education requirements. For example, you may be able to build necessary skills in an online coding boot camp, but some employers may also seek candidates with a degree. Before deciding on a specific learning path, research the roles you hope to pursue and tailor your coursework to your professional aspirations. 

How to use Swagger UI in your career

Software developers and other professionals use Swagger UI to build and test APIs. It provides a graphical user interface for interacting with and testing APIs, making it easier for developers to understand and use the API they are building. 

Developers use Swagger UI day-to-day in a variety of useful applications. API developers, who are responsible for building and maintaining APIs, rely on Swagger UI to interact with and test the APIs they are building. Meanwhile, quality assurance engineers might use Swagger UI to test APIs built by other developers to ensure they function as intended and are bug-free.

When you learn Swagger UI, you can join a community of developers interested in the same topics as you and share practical lessons and tips with one another.Footnote 7
