OpenAPI: Beginner to Guru
What you'll learn
- Learn to define APIs using OpenAPI Specifications
- Create awesome API Documentation with Swagger UI
- Edit OpenAPI Specifications in Swagger Hub
- Be able to edit text files
- Knowledge of RESTful APIs and JSON helpful
OpenAPI 3.0 is the leading tool for the documentation of APIs.
Formerly known as Swagger, OpenAPI has a long and established history. In 2010, Swagger started as an open source specification for designing and documenting RESTful APIs.
In 2015, the Swagger project was acquired by SmartBear Software. The Swagger Specification was donated to the Linux foundation and renamed the OpenAPI.
The OpenAPI specification is the cornerstone of a thriving open source community. Simply perform a search for OpenAPI tools and you will find projects for converters, documentation, validators, editors, mock servers, testing tools and much much more!
From the OpenAPI specification, you can generate client side source code for over 50 languages. You can generate server side code for over 40 different languages.
All of these open source contributes start with the OpenAPI specification, which we explore in depth in this course.
You start off the course with learning about what is an API, a review of the HTTP protocol and how it is used in respect to RESTFul APIs.
Then we start looking at OpenAPI and how it applies to documenting RESTFul APIs.
We then start writing an OpenAPI specification using Swagger Hub.
Swagger Hub is a free, easy to use on-line editor for Swagger and OpenAPI specifications.
You will get to create a complete OpenAPI specification for a RESTful web service.
Step by step, you learn how to:
Edit a OpenAPI specification in Swagger Hub
Define a OpenAPI specification in YAML
Add developer information
Add server information
Define an API path
Define an API operation
Create robust objects with JSON schema constraints
Improve the quality of your specification with re-useable components.
Define query parameters
Define path parameters
Define GET, PUT, POST, and DELETE operations
Create API security schemes
Generate source code with OpenAPI Code Gen
Use ReDoc to generate robust API documentation
Use Apache Maven to generate code with OpenAPI Code Gen
This course has numerous assignments and hands on examples to get you comfortable writing OpenAPI specifications.

Hi. I'm John.
I've been in the IT industry for over 25 years. Today, I specialize mainly in Java, the most successful and widely known programming language in use today. I also specialize with the Spring Framework, which the most popular open source application framework for building enterprise class applications on the Java platform. Just some of the organizations I've worked with include Visa, Kohls, Federal Home Loan Bank, and Belk Department Stores.
Through the courses I'm providing, I hope to leverage my years of experience to accelerate your learning of the Spring Framework. I'm not going to lie to you. The Spring Framework is a big framework. The environment for enterprise Java is even bigger. If you're new to Java, you have a lot to learn. I hope through the content on this web site I can accelerate your education of the Java and Spring landscape.
Spring Ahead Code Academy was established by John Thompson, founder of Spring Framework Guru. John has over 25 years of programming experience and has taught over 250,000 students in 180 different countries.
Spring Ahead Code Academy is collation of experienced professional developers helping others learn to code.
Our goal is to bring together real world professionals, to share real world experience with you. We hope to help you with your journey in learning new skills and growing your career.
