Learn Swagger and the OpenAPI Specification
What you'll learn
- Read and write Open API Specification (Swagger) files to define and document APIs
- Use Swagger tools to edit files, create documentation, and create SDKs
- Understand alternatives to Swagger and OAS.
- You should understand how REST APIs work
- You should be able to read and understand JSON
- If you need these skills, take my courses on JSON/XML and REST
The OpenAPI Specification (often called "Swagger") is currently the most popular way to create definitions of RESTful APIs. With these definitions, you can create sophisticated, autogenerated documentation, generate SDKs in several languages, and do automated testing. Swagger is a set of open source tools that use these Open API Specification definition files.
This class is for people in the software industry who are fairly technical, but are not software developers: for example, project managers, API product managers, and technical writers. It assumes that you understand REST and JSON, but that's about all. It is meant to be for people who are new to the Open API Specification and Swagger, rather than for experts. It covers:
What you can do with OpenAPI Specification (OAS) files
The YAML file format
How to create an OAS file
How to specify security
How to add documentation
How to write an OAS file in JSON
Alternatives to Swagger and OAS
This class does not cover:
How to set up Swagger on your own server
How to modify Swagger open source code
In addition to videos, this course contains 8 hands-on exercises that lead you step-by-step in creating an API definition file, including a final project where you create a file from scratch using documentation from an actual commercial API. It also contains a document with resources on learning more about OAS, Swagger, and alternatives.
In addition to the video lectures, expect to spend at least 4 hours doing the exercises. These exercises are key to understanding Swagger and OAS.
Important: The course uses OAS 2. A newer version, OAS 3, is starting to be used more, but many companies are still using OAS 2. There is a lecture that points you to the differences between OAS 2 and OAS 3.
Who this course is for:
- Anyone who wants to be able to read or write Open API Specification (Swagger) files
- Project managers
- Technical writers
- Technical sales staff
- Technically-skilled managers
Peter founded SDK Bridge to bring together his love of technology and writing. After 10 years as a software developer, he learned the skill of API writing at Microsoft. Since then, he has worked as an API writer to describe APIs for eCommerce, automobile traffic prediction, electric utilities, mobile phones, and tractors, just to name a few. In addition to API and SDK documentation, he creates video tutorials for software developer audiences. Peter received his BA in Physics from the University of Chicago and his PhD in Applied Physics from Stanford University.
