## 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.
|
|
|
|
|
|
|
|
## 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**.

## Releases
|
|
**Important:** all the 2.x releases are deployed to npm and can be used with Redocly-cdn:
|
|
- particular release, for example, `v2.0.0`: https://cdn.redoc.ly/redoc/v2.0.0/bundles/redoc.standalone.js
|
|
- `latest` release: https://cdn.redoc.ly/redoc/latest/bundles/redoc.standalone.js

|
|
Additionally, all the 1.x releases are hosted on our GitHub Pages-based CDN **(deprecated)**:
|
|
- particular release, for example `v1.2.0`: https://rebilly.github.io/ReDoc/releases/v1.2.0/redoc.min.js
|
|

## Lint OpenAPI definitions
|
|
|
|
Redocly CLI is an [open source command-line tool](https://github.com/Redocly/redocly-cli) that you can use to lint
|
|
your OpenAPI definition. 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
|
|
<!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.redoc.ly/redoc/latest/bundles/redoc.standalone.js"> </script>
|
|
</body>
|
|
</html>
|
|
|
|
```
|
|
|
|
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
|
|
|
|
### `<redoc>` options object
|
|
You can use all of the following options with the standalone version of the <redoc> 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.
|
|
