Documenting with OpenAPI
Documentation is a critical part of any API development process. Good documentation makes your API more accessible and easier to use. In a world where APIs are increasingly the primary interface between systems, having clear, accurate, and comprehensive documentation is no longer optional; it’s essential. For documenting REST APIs, the de facto standard is OpenAPI, and how it works and integrates with Go is what we will explore in this chapter. For that, we are going to learn about the following concepts:
- What OpenAPI is and why it’s important
- How to document your endpoints with OpenAPI
- Tools for working with the OpenAPI Specification (OAS)
- Publishing your API documentation
- Adding OpenAPI documentation to our shopping list API
In this chapter, we’ll use some applications that require node, npm, and npx to be installed on your system. Ensure that you have them installed if you want to follow all...
