Technical Documentation

What this API does

Redoc API Documentation Tool is an advanced open-source platform that converts OpenAPI 3.0, 3.1, and Swagger 2.0 specifications into visually appealing and interactive API documentation. It supports multiple integration methods such as CLI tools, Docker containers, React components, and simple HTML embeds, allowing developers to easily generate a professional documentation site from YAML or JSON files.

How it works

The tool utilizes OpenAPI specifications to create documentation in a user-friendly three-panel layout, integrating search features and displaying detailed endpoints. Developers can easily embed the generator in their applications or host it independently, allowing for both public and private documentation without the need for extensive configuration.

Authentication

No authentication is required to use Redoc API Documentation Tool. Developers can freely utilize its features without needing API keys or tokens, making it accessible immediately.

Example usage

  • redocly build-docs --spec ./path/to/openapi.yaml - Generates documentation from the specified OpenAPI YAML file.
  • docker run redocly/redoc - Runs the Redoc server in a Docker container to serve documentation.
  • npm install @redocly/cli -g - Installs the Redoc CLI for easy command-line usage.

Ideal use cases

  • Generating documentation for public APIs to enhance usability.
  • Creating internal documentation for development teams to streamline API consumption.
  • Embedding interactive API documentation within web applications.
  • Supporting open-source projects with well-documented APIs.
