Live demo

Features

  • Extremely easy deployment
  • The widest OpenAPI features support (yes, it supports even discriminator)
  • Neat interactive documentation for nested objects
  • Code samples support (via vendor extension)
  • Progressive loading with lazy-rendering options
  • Responsive three-panel design with menu/scrolling synchronization
  • Integrate API Introduction into side menu - ReDoc takes advantage of markdown headings from OpenAPI description field. It pulls them into side menu and also supports deep linking.
  • High-level grouping in side-menu via x-tagGroups vendor extension
  • Multiple ReDoc instances on single page (example)

Roadmap

  • performance optimizations
  • better navigation (menu improvements + search)
  • ability to simple branding/styling
  • built-in API Console
  • docs pre-rendering (performance and SEO)

Releases

We host the latest and all the previous ReDoc releases on GitHub Pages-based CDN:

Some Real-life usages

Deployment

TL;DR

<!DOCTYPE html>
<html>
  <head>
    <title>ReDoc</title>
    <!-- needed for adaptive design -->
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!--
    ReDoc doesn't change outer page styles
    -->
    <style>
      body {
        margin: 0;
        padding: 0;
      }
    </style>
  </head>
  <body>
    <redoc spec-url='http://petstore.swagger.io/v2/swagger.json'></redoc>
    <script src="https://rebilly.github.io/ReDoc/releases/latest/redoc.min.js"> </script>
  </body>
</html>

That's all folks!

1. Install ReDoc (skip this step for CDN)

Install using bower:

bower install redoc

or using npm:

npm install redoc --save

2. Reference redoc script in HTML

For CDN:

<script src="https://rebilly.github.io/ReDoc/releases/latest/redoc.min.js"> </script>

For bower:

<script src="bower_components/redoc/dist/redoc.min.js"> </script>

For npm:

<script src="node_modules/redoc/dist/redoc.min.js"> </script>

3. Add <redoc> element to your page

<redoc spec-url="url/to/your/spec"></redoc>

4. Enjoy 😄

Configuration

Security Definition location

You can inject Security Definitions widget into any place of your specification description. Check out details here.

Swagger vendor extensions

ReDoc makes use of the following vendor extensions:

  • x-logo - is used to specify API logo
  • x-traitTag - useful for handling out common things like Pagination, Rate-Limits, etc
  • x-code-samples - specify operation code samples
  • x-nullable - mark schema param as a nullable
  • x-displayName - specify human-friendly names for the menu categories
  • x-tagGroups - group tags by categories in the side menu
  • x-servers - ability to specify different servers for API (backported from OpenAPI 3.0)

<redoc> tag attributes

  • spec-url - relative or absolute url to your spec file;
  • scroll-y-offset - If set, specifies a vertical scroll-offset. This is often useful when there are fixed positioned elements at the top of the page, such as navbars, headers etc; scroll-y-offset can be specified in various ways:
    • number: A fixed number of pixels to be used as offset;
    • selector: selector of the element to be used for specifying the offset. The distance from the top of the page to the element's bottom will be used as offset;
    • function: A getter function. Must return a number representing the offset (in pixels);
  • suppress-warnings - if set, warnings are not rendered at the top of documentation (they still are logged to the console).
  • lazy-rendering - if set, enables lazy rendering mode in ReDoc. This mode is useful for APIs with big number of operations (e.g. > 50). In this mode ReDoc shows initial screen ASAP and then renders the rest operations asynchronously while showing progress bar on the top. Check out the demo for the example.
  • hide-hostname - if set, the protocol and hostname is not shown in the method definition.
  • expand-responses - specify which responses to expand by default by response codes. Values should be passed as comma-separated list without spaces e.g. expand-responses="200,201". Special value "all" expands all responses by default. Be careful: this option can slow-down documentation rendering time.
  • required-props-first - show required properties first ordered in the same order as in required array.

Advanced usage

Instead of adding spec-url attribute to the <redoc> element you can initialize ReDoc via globally exposed Redoc object:

Redoc.init(specUrl, options)

options is javascript object with camel-cased version of <redoc> tag attribute names as the keys, e.g.:

Redoc.init('http://petstore.swagger.io/v2/swagger.json', {
  scrollYOffset: 50
})

Development

Running local dev-server

  • Clone repository git clone https://github.com/Rebilly/ReDoc.git
  • Go to the project folder cd ReDoc
  • Install dependencies npm install
  • (optional) Replace demo/swagger.yaml with your own schema
  • Start the server npm start
  • Open http://localhost:9000

Alternatively, Docker can be used by just running docker-compose up.
