Description

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.

As a complete newbie of OpenAPI, I found this course very practical. I appreciate a lot the format of this course. Every section starts with an overview, then digs a little bit in the specification, continues with an example, and gives you one or two assignments to practice.

Hi. I'm John.

I've been in the IT industry for over 20 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.
