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">
    <link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,700|Roboto:300,400,700" rel="stylesheet">

    <!--
    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://cdn.jsdelivr.net/npm/redoc@next/bundles/redoc.standalone.js"> </script>
  </body>
</html>

That's all folks!

IMPORTANT NOTE: if you work with untrusted user spec, use untrusted-spec option to prevent XSS security risks.

1. Install ReDoc (skip this step for CDN)

Install using npm:

npm i redoc

or using yarn:

yarn add redoc

2. Reference redoc script in HTML

For CDN:

<script src="https://cdn.jsdelivr.net/npm/redoc/bundles/redoc.standalone.js"> </script>

For npm:

<script src="node_modules/redoc/bundles/redoc.standalone.js"> </script>

3. Add <redoc> element to your page

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

4. Enjoy 😄

Usage as a React component

Install peer dependencies required by ReDoc if you don't have them installed already:

npm i react react-dom mobx styled-components core-js

Import RedocStandalone component from 'redoc' module:

import { RedocStandalone } from 'redoc';

and use it somewhere in your component:

<RedocStandalone specUrl="url/to/your/spec"/>

or

<RedocStandalone spec={/* spec as an object */}/>

Also you can pass options:

<RedocStandalone
  specUrl="https://api.redoc.ly/registry/rebilly/core-api/core/bundle/master/openapi.yaml"
  options={{
    nativeScrollbars: true,
    theme: { colors: { primary: { main: '#dd5522' } } },
  }}
/>

Here are detailed options docs.

You can also specify onLoaded callback which will be called each time Redoc has been fully rendered or when error occurs (with an error as the first argument). NOTE: It may be called multiply times if you change component properties

<RedocStandalone
  specUrl="https://api.redoc.ly/registry/rebilly/core-api/core/bundle/master/openapi.yaml"
  onLoaded={error => {
    if (!error) {
      console.log('Yay!');
    }
  }}
/>

IE11 Support Notes

The Docker way

ReDoc is available as pre-built Docker image in official Docker Hub repository. You may simply pull & run it:

docker pull redocly/redoc
docker run -p 8080:80 redocly/redoc

Also you may rewrite some predefined environment variables defined in Dockerfile. By default ReDoc starts with demo Petstore spec located at http://petstore.swagger.io/v2/swagger.json, but you may change this URL using environment variable SPEC_URL:

docker run -p 8080:80 -e SPEC_URL=https://api.example.com/openapi.json redocly/redoc

ReDoc CLI

See here

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-codeSamples - specify operation code samples
  • x-examples - specify JSON example for requests
  • 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)
  • x-ignoredHeaderParameters - ability to specify header parameter names to ignore
  • x-additionalPropertiesName - ability to supply a descriptive name for the additional property keys
  • x-summary - For Response object, use as the response button text, with description rendered under the button
  • x-extendedDiscriminator - In Schemas, uses this to solve name-clash issues with the standard discriminator
  • x-explicitMappingOnly - In Schemas, display a more descriptive property name in objects with additionalProperties when viewing the property list with an object

<redoc> options object

You can use all of the following options with standalone version on tag by kebab-casing them, e.g. scrollYOffset becomes scroll-y-offset and expandResponses becomes expand-responses.

  • disableSearch - disable search indexing and search box.
  • expandDefaultServerVariables - enable expanding default server variables, default false.
  • expandResponses - specify which responses to expand by default by response codes. Values should be passed as comma-separated list without spaces e.g. expandResponses="200,201". Special value "all" expands all responses by default. Be careful: this option can slow-down documentation rendering time.
  • maxDisplayedEnumValues - display only specified number of enum values. hide rest values under spoiler.
  • hideDownloadButton - do not show "Download" spec button. THIS DOESN'T MAKE YOUR SPEC PRIVATE, it just hides the button.
  • hideHostname - if set, the protocol and hostname is not shown in the operation definition.
  • hideLoading - do not show loading animation. Useful for small docs.
  • hideSchemaPattern - if set, the pattern is not shown in the schema.
  • hideSingleRequestSampleTab - do not show the request sample tab for requests with only one sample.
  • expandSingleSchemaField - automatically expand single field in a schema
  • jsonSampleExpandLevel - set the default expand level for JSON payload samples (responses and request body). Special value "all" expands all levels. The default value is 2.
  • hideSchemaTitles - do not display schema title next to to the type
  • simpleOneOfTypeLabel - show only unique oneOf types in the label without titles
  • lazyRendering - Not implemented yet 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.
  • menuToggle - if true clicking second time on expanded menu item will collapse it, default true.
  • nativeScrollbars - use native scrollbar for sidemenu instead of perfect-scroll (scrolling performance optimization for big specs).
  • noAutoAuth - do not inject Authentication section automatically.
  • onlyRequiredInSamples - shows only required fields in request samples.
  • pathInMiddlePanel - show path link and HTTP verb in the middle panel instead of the right one.
  • requiredPropsFirst - show required properties first ordered in the same order as in required array.
  • scrollYOffset - 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; scrollYOffset 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).
  • showExtensions - show vendor extensions ("x-" fields). Extensions used by ReDoc are ignored. Can be boolean or an array of string with names of extensions to display.
  • sortPropsAlphabetically - sort properties alphabetically.
  • payloadSampleIdx - if set, payload sample will be inserted at this index or last. Indexes start from 0.
  • theme - ReDoc theme. For details check theme docs.
  • untrustedSpec - if set, the spec is considered untrusted and all HTML/markdown is sanitized to prevent XSS. Disabled by default for performance reasons. Enable this option if you work with untrusted user data!

Advanced usage of standalone version

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

Redoc.init(specOrSpecUrl, options, element, callback?)
  • specOrSpecUrl is either JSON object with specification or an URL to the spec in JSON or YAML format
  • options options object
  • element DOM element to put ReDoc into
  • callback (optional) - callback to be called after Redoc has been fully rendered. It is also called on errors with error as the first argument
Redoc.init('http://petstore.swagger.io/v2/swagger.json', {
  scrollYOffset: 50
}, document.getElementById('redoc-container'))
