OpenAPI/Swagger-generated API Reference Documentation

This is the README for the 2.x version of Redoc (React-based). The README for the 1.x version is on the v1.x branch

Live demo

Features

• Multiple deployment options

• Server-side rendering (SSR) ready

• Simple integration with create-react-app

  See an example

• Command-line interface to bundle your docs into a zero-dependency HTML file

• Responsive three-panel design with menu/scrolling synchronization

• Deep linking support

• Ability to integrate your API introduction into the side menu

• High-level grouping in side-menu via x-tagGroups specification extension

• Branding/customizations using the theme option

• OpenAPI v3.0 support

• Basic OpenAPI v3.1 support

• Broad OpenAPI v2.0 feature support (yes, it supports even discriminator)
  

• Neat interactive documentation for nested objects
  

• Code samples support (via vendor extension)
  

Releases

Important: all the 2.x releases are deployed to npm and can be used with jsdeliver:

• particular release, for example, v2.0.0-alpha.15: https://cdn.jsdelivr.net/npm/redoc@2.0.0-alpha.17/bundles/redoc.standalone.js
• next release: https://cdn.jsdelivr.net/npm/redoc@next/bundles/redoc.standalone.js

Additionally, all the 1.x releases are hosted on our GitHub Pages-based CDN (deprecated):

• particular release, e.g. v1.2.0: https://rebilly.github.io/ReDoc/releases/v1.2.0/redoc.min.js
• v1.x.x release: https://rebilly.github.io/ReDoc/releases/v1.x.x/redoc.min.js
• latest release: https://rebilly.github.io/ReDoc/releases/latest/redoc.min.js - it will point to latest 1.x.x release since 2.x releases are not hosted on this CDN but on unpkg.

Deployment

For step-by-step instructions for how to get started using Redoc to render your OpenAPI definition, refer to the Redoc quickstart guide.

IE11 Support Notes

ReDoc CLI

For more information on Redoc's commmand-line interface, refer to Using the Redoc CLI.

Configuration

Security Definition location

You can inject the Security Definitions widget into any place in your definition description. For more information, refer to Security definitions injection.

OpenAPI specification extensions

Redoc uses the following specification 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 the standalone version of the tag by kebab-casing them. For example, 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!
