**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](https://github.com/Redocly/redoc/tree/v1.x) branch.** ## About Redoc Redoc is an open-source tool for generating documentation from OpenAPI (fka Swagger) definitions. By default Redoc offers a three-panel, responsive layout: - The left panel contains a search bar and navigation menu. - The central panel contains the documentation. - The right panel contains request and response examples. ![Redoc demo](https://raw.githubusercontent.com/Redocly/redoc/main/demo/redoc-demo.png) ## Live demo If you want to see how Redoc renders your OpenAPI definition, you can try it out online at https://redocly.github.io/redoc/. A version of the Swagger Petstore API is displayed by default. To test it with your own OpenAPI definition, enter the URL for your definition and select **TRY IT**. ## Redoc vs. Reference vs. Portals Redoc is Redocly's community-edition product.

Linting helps you to catch errors and inconsistencies in your OpenAPI definition before publishing. Learn more about [API standards and linting](https://redocly.com/docs/cli/api-standards/) in the main Redocly documentation. ## Deployment ### TL;DR final code example To render your OpenAPI definition using Redoc, use the following HTML code sample and replace the `spec-url` attribute with the url or local file address to your definition. ```html Redoc ``` For step-by-step instructions for how to get started using Redoc to render your OpenAPI definition, refer to the [**Redoc quickstart guide**](https://redocly.com/docs/redoc/quickstart/) and [**How to use the HTML element**](https://redocly.com/docs/redoc/deployment/html/). ## 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](docs/security-definitions-injection.md). ### OpenAPI specification extensions Redoc uses the following [specification extensions](https://redocly.com/docs/api-reference-docs/spec-extensions/): * [`x-logo`](docs/redoc-vendor-extensions.md#x-logo) - is used to specify API logo * [`x-traitTag`](docs/redoc-vendor-extensions.md#x-traitTag) - useful for handling out common things like Pagination, Rate-Limits, etc * [`x-codeSamples`](docs/redoc-vendor-extensions.md#x-codeSamples) - specify operation code samples * [`x-examples`](docs/redoc-vendor-extensions.md#x-examples) - specify JSON example for requests * [`x-nullable`](docs/redoc-vendor-extensions.md#x-nullable) - mark schema param as a nullable * [`x-displayName`](docs/redoc-vendor-extensions.md#x-displayname) - specify human-friendly names for the menu categories * [`x-tagGroups`](docs/redoc-vendor-extensions.md#x-tagGroups) - group tags by categories in the side menu * [`x-servers`](docs/redoc-vendor-extensions.md#x-servers) - ability to specify different servers for API (backported from OpenAPI 3.0) * [`x-ignoredHeaderParameters`](docs/redoc-vendor-extensions.md#x-ignoredHeaderParameters) - ability to specify header parameter names to ignore * [`x-additionalPropertiesName`](docs/redoc-vendor-extensions.md#x-additionalPropertiesName) - ability to supply a descriptive name for the additional property keys * [`x-summary`](docs/redoc-vendor-extensions.md#x-summary) - For Response object, use as the response button text, with description rendered under the button * [`x-extendedDiscriminator`](docs/redoc-vendor-extensions.md#x-extendedDiscriminator) - In Schemas, uses this to solve name-clash issues with the standard discriminator * [`x-explicitMappingOnly`](docs/redoc-vendor-extensions.md#x-explicitMappingOnly) - In Schemas, display a more descriptive property name in objects with additionalProperties when viewing the property list with an object ### `` 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. * `minCharacterLengthToInitSearch` - set minimal characters length to init search, default `3`, minimal `1`. * `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. * `generatedPayloadSamplesMaxDepth` - set the maximum render depth for JSON payload samples (responses and request body). The default value is `10`. * `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. * `downloadFileName` - set a custom file name for the downloaded API definition file. * `downloadDefinitionUrl` - If the 'Download' button is visible in the API reference documentation (hideDownloadButton=false), the URL configured here opens when that button is selected. Provide it as an absolute URL with the full URI scheme. * `hideHostname` - if set, the protocol and hostname is not shown in the operation definition. * `hideLoading` - do not show loading animation. Useful for small docs. * `hideFab` - do not show FAB in mobile view. Useful for implementing a custom floating action button. * `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. * `showObjectSchemaExamples` - show object schema example in the properties, default `false`. * `expandSingleSchemaField` - automatically expand single field in a schema * `schemaExpansionLevel` - specifies whether to automatically expand schemas. Special value `"all"` expands all levels. The default value is `0`. * `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 * `sortEnumValuesAlphabetically` - set to true, sorts all enum values in all schemas alphabetically * `sortOperationsAlphabetically` - set to true, sorts operations in the navigation sidebar and in the middle panel alphabetically * `sortTagsAlphabetically` - set to true, sorts tags in the navigation sidebar and in the middle panel alphabetically * `menuToggle` - if true, clicking second time on expanded menu item collapses it, default `true`. * `nativeScrollbars` - use native scrollbar for sidemenu instead of perfect-scroll (scrolling performance optimization for big specs). * `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 is 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 is inserted at this index or last. Indexes start from 0. * `theme` - Redoc theme. For details check [theme docs](#redoc-theme-object). * `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!** * `nonce` - if set, the provided value is injected in every injected HTML element in the `nonce` attribute. Useful when using CSP, see https://webpack.js.org/guides/csp/. * `sideNavStyle` - can be specified in various ways: * **summary-only**: displays a summary in the sidebar navigation item. (**default**) * **path-only**: displays a path in the sidebar navigation item. * **id-only**: displays the operation id with a fallback to the path in the sidebar navigation item. * `showWebhookVerb` - when set to `true`, shows the HTTP request method for webhooks in operations and in the sidebar. ### `` theme object * `spacing` * `unit`: 5 # main spacing unit used in autocomputed theme values later * `sectionHorizontal`: 40 # Horizontal section padding.
