Writing Tools



Product Overview of ReDoc

ReDoc is an open-source API documentation tool designed to generate interactive and user-friendly documentation from OpenAPI definitions. Here’s a detailed look at what ReDoc does and its key features:



What ReDoc Does

ReDoc converts your OpenAPI definitions into web-ready, interactive API documentation. It supports OpenAPI 3.1, 3.0, and older versions such as OpenAPI 2.0 and Swagger 2.0. This tool is particularly useful for developers and teams looking to create clear, navigable, and visually appealing API documentation.



Key Features and Functionality



Layout and Navigation

  • ReDoc features a responsive three-panel layout, which includes a left panel for navigation, a middle panel for detailed endpoint and method documentation, and a right panel for request and response samples, as well as code samples.


Interactive Documentation

  • The tool provides interactive documentation with features like scroll-synchronized reference menus, nested schema support, and the ability to collapse or expand sections. This makes it easier for users to navigate complex API structures.


Payload Documentation

  • ReDoc excels in documenting complex request and response payloads, including support for nested schemas, discriminators, and detailed header and payload documentation. Payload samples are generated based on JSON-schema, utilizing fields such as default, enum, and example.


Customization and Branding

  • Users can customize the documentation with features like integrating API introductions into the side menu using Markdown headings, high-level grouping via x-tagGroups vendor extensions, and branding options such as displaying a custom logo using the x-logo vendor extension.


Code Samples and Vendor Extensions

  • ReDoc supports custom code samples via OpenAPI vendor extensions, allowing for more comprehensive documentation. It also integrates with tools like create-react-app for seamless integration into existing projects.


Deployment and Automation

  • The tool offers extremely easy deployment options, including the ability to bundle documentation into a zero-dependency HTML file using the redoc-cli. It is also Server Side Rendering (SSR) ready, making it versatile for various deployment scenarios.


CLI Tool and Automation

  • ReDoc is provided as a CLI tool, which allows for easy automation and local development. Commands like npx @redocly/cli build-docs openapi.yaml enable quick generation of documentation from OpenAPI definitions.


Additional Features

  • Advanced Search and Navigation: The premium version of ReDoc, offered through Redocly, includes advanced search capabilities, version switching, and enhanced schema navigation.
  • Mock Server and Try-it Console: Premium features also include a try-it console for testing API requests and mock server functionality, enhancing the interactive experience.
  • Performance Optimizations: ReDoc is optimized for performance, especially for large OpenAPI files, ensuring smooth rendering and navigation.

In summary, ReDoc is a powerful tool for generating interactive and customizable API documentation from OpenAPI definitions, making it an invaluable resource for developers and teams aiming to create high-quality, user-friendly API documentation.
