About redoc
Redoc is an open source tool for generating API reference documentation from OpenAPI definitions, formerly known as Swagger. It lives in the JavaScript and TypeScript ecosystem, ships under the MIT license, and is published on npm as the redoc package. By default it renders a responsive three panel layout: a left panel holding the search bar and navigation menu, a central panel holding the documentation itself, and a right panel showing request and response examples.
