What are some popular ways to document REST APIs, and what are the benefits of each approach?

Swagger/OpenAPI is an open-source framework that allows developers to describe, produce, and consume RESTful APIs, making it a popular choice for documenting REST APIs.

API documentation generators like Swagger UI and Swagger Codegen can automatically generate API documentation and client code, making it easier to maintain and update API documentation.

API Blueprint is a markdown-based format for describing APIs, which makes it easy to write and read, and is a popular alternative to Swagger.

Dox is a JavaScript-based tool that generates API documentation from JavaScript code, providing an easy way to document APIs.

Aglio is a documentation generator that uses API Blueprint to generate beautiful API documentation, making it a popular choice among developers.

Documenting REST APIs is crucial for clarity and usability, as it provides essential information on how the API functions, making it easier for developers to understand and effectively utilize the API.

Well-documented APIs facilitate quicker and more efficient integration, as they provide a clear understanding of the API's functionality and usage.

The Fetch API is a modern browser API that allows developers to make asynchronous HTTP requests from client-side JavaScript code, making it useful for documenting REST APIs.

Having simple, human-friendly documentation for developers to work off of is helpful, even for APIs that use HATEOAS (Hypermedia As The Engine Of Application State) and are hypertext-driven with heavy use of media types.

Generating documentation using tools like Swagger can be crucial for success in the API economy, as it provides a clear understanding of the API's functionality and usage.

Creating and maintaining good documentation that is easy to read, enjoyable to interact with, and sets the API up for success is a key aspect of API development.

Structuring documentation in a logical and organized way, such as grouping APIs by functionality, is essential for making it easy for developers to understand and use the API.

Providing a nice introduction and overview of the API, followed by detailed documentation of each endpoint, is a best practice for documenting REST APIs.

Including tutorials and examples in API documentation can help developers understand how to use the API and provide context for the documentation.

Documenting REST APIs helps provide a quick reference guide that covers all you need to know about the API, including details on functions, classes, return types, arguments, and more.
