**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/master/demo/redoc-demo.png)
## Live demo
If you want to see how Redoc will render 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 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, for example `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.

## Lint OpenAPI definitions
Redocly's OpenAPI CLI is an open source command-line tool that you can use to lint
your OpenAPI definition. Linting helps you to catch errors and inconsistencies in your
OpenAPI definition before publishing.
Refer to [Lint configuration](https://redoc.ly/docs/cli/guides/lint/) in the OpenAPI documentation for more information.
## 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.jsdelivr.net/npm/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://redoc.ly/docs/redoc/quickstart/intro/).
## Redoc CLI
For more information on Redoc's commmand-line interface, refer to
[**Using the Redoc CLI**](https://redoc.ly/docs/redoc/quickstart/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](docs/security-definitions-injection.md).
### OpenAPI specification extensions
Redoc uses the following [specification extensions](https://swagger.io/specification/#specificationExtensions):
* [`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.
* `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.
* `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
* `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](\\redocly.github.io/redoc) 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](#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 will be 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.
