Swagger UI

, _(*1)

New!

This is the new version of swagger-ui, 3.x. Want to learn more? Check out our FAQ., _(*2)

👉🏼 Want to score an easy open-source contribution? Check out our Good first issue label., _(*3)

As a brand new version, written from the ground up, there are some known issues and unimplemented features. Check out the Known Issues section for more details., _(*4)

This repository publishes to two different NPM modules:, _(*5)

swagger-ui is a traditional npm module intended for use in JavaScript web application projects that are capable of resolving dependencies (via Webpack, Browserify, etc).
swagger-ui-dist is a dependency-free module that includes everything you need to serve Swagger-UI in a server-side project, or a web project that can't resolve npm module dependencies.

For the older version of swagger-ui, refer to the 2.x branch., _(*6)

Compatibility

The OpenAPI Specification has undergone 5 revisions since initial creation in 2010. Compatibility between swagger-ui and the OpenAPI Specification is as follows:, _(*7)

Swagger UI Version	Release Date	OpenAPI Spec compatibility	Notes
3.4.3	2017-11-03	2.0, 3.0	tag v3.4.3
3.0.21	2017-07-26	2.0	tag v3.0.21
2.2.10	2017-01-04	1.1, 1.2, 2.0	tag v2.2.10
2.1.5	2016-07-20	1.1, 1.2, 2.0	tag v2.1.5
2.0.24	2014-09-12	1.1, 1.2	tag v2.0.24
1.0.13	2013-03-08	1.1, 1.2	tag v1.0.13
1.0.1	2011-10-11	1.0, 1.1	tag v1.0.1

How to run

Easy start! Docker

You can pull a pre-built docker image of the swagger-ui directly from Dockerhub:, _(*8)

docker pull swaggerapi/swagger-ui
docker run -p 80:8080 swaggerapi/swagger-ui

Will start nginx with swagger-ui on port 80., _(*9)

Or you can provide your own swagger.json on your host, _(*10)

docker run -p 80:8080 -e SWAGGER_JSON=/foo/swagger.json -v /bar:/foo swaggerapi/swagger-ui

Prerequisites

Node 6.x
NPM 3.x

If you just want to see your specs, open dist/index.html in your browser directly from your filesystem., _(*11)

If you'd like to make modifications to the codebase, run the dev server with: npm run dev. A development server will open on 3200., _(*12)

If you'd like to rebuild the /dist folder with your codebase changes, run npm run build., _(*13)

Integration Tests

You will need JDK of version 7 or higher as instructed here http://nightwatchjs.org/gettingstarted#selenium-server-setup, _(*14)

Integration tests can be run locally with npm run e2e - be sure you aren't running a dev server when testing!, _(*15)

Browser support

Swagger UI works in the latest versions of Chrome, Safari, Firefox, Edge and IE11., _(*16)

Known Issues

To help with the migration, here are the currently known issues with 3.X. This list will update regularly, and will not include features that were not implemented in previous versions., _(*17)

Only part of the parameters previously supported are available.
The JSON Form Editor is not implemented.
Support for collectionFormat is partial.
l10n (translations) is not implemented.
Relative path support for external files is not implemented.

Direct use of JS and CSS assets

To include the JS, CSS and image assets directly into a webpage, use the swagger-ui-dist package. The root directory of this package contains the contents of the dist/ directory of this repo. As a node module, swagger-ui-dist also exports the swagger-ui-bundle and swagger-ui-standalone-preset objects., _(*18)

SwaggerUIBundle

To use swagger-ui's bundles, you should take a look at the source of swagger-ui html page and customize it. This basically requires you to instantiate a SwaggerUi object as below:, _(*19)

  const ui = SwaggerUIBundle({
      url: "http://petstore.swagger.io/v2/swagger.json",
      dom_id: '#swagger-ui',
      presets: [
        SwaggerUIBundle.presets.apis,
        SwaggerUIStandalonePreset
      ],
      plugins: [
        SwaggerUIBundle.plugins.DownloadUrl
      ],
      layout: "StandaloneLayout"
    })

OAuth2 configuration

You can configure OAuth2 authorization by calling initOAuth method with passed configs under the instance of SwaggerUIBundle default client_id and client_secret, realm, an application name appName, scopeSeparator, additionalQueryStringParams, useBasicAuthenticationWithAccessCodeGrant., _(*20)

Config Name	Description
client_id	Default clientId. MUST be a string
client_secret	Default clientSecret. MUST be a string
realm	realm query parameter (for oauth1) added to `authorizationUrl` and `tokenUrl` . MUST be a string
appName	application name, displayed in authorization popup. MUST be a string
scopeSeparator	scope separator for passing scopes, encoded before calling, default value is a space (encoded value `%20`). MUST be a string
additionalQueryStringParams	Additional query parameters added to `authorizationUrl` and `tokenUrl`. MUST be an object
useBasicAuthenticationWithAccessCodeGrant	Only activated for the `accessCode` flow. During the `authorization_code` request to the `tokenUrl`, pass the Client Password using the HTTP Basic Authentication scheme (`Authorization` header with `Basic base64encoded[client_id:client_secret]`). The default is `false`

const ui = SwaggerUIBundle({...})

// Method can be called in any place after calling constructor SwaggerUIBundle
ui.initOAuth({
    clientId: "your-client-id",
    clientSecret: "your-client-secret-if-required",
    realm: "your-realms",
    appName: "your-app-name",
    scopeSeparator: " ",
    additionalQueryStringParams: {test: "hello"}
  })

If you'd like to use the bundle files via npm, check out the swagger-ui-dist package., _(*21)

Parameters

Parameters with dots in their names are single strings used to organize subordinate parameters, and are not indicative of a nested structure., _(*22)

Parameter Name	Description
url	The url pointing to API definition (normally `swagger.json` or `swagger.yaml`). Will be ignored if `urls` or `spec` is used.
urls	An array of API definition objects (`{url: "<url>", name: "<name>"}`) used by Topbar plugin. When used and Topbar plugin is enabled, the `url` parameter will not be parsed. Names and URLs must be unique among all items in this array, since they're used as identifiers.
urls.primaryName	When using `urls`, you can use this subparameter. If the value matches the name of a spec provided in `urls`, that spec will be displayed when Swagger-UI loads, instead of defaulting to the first spec in `urls`.
spec	A JSON object describing the OpenAPI Specification. When used, the `url` parameter will not be parsed. This is useful for testing manually-generated specifications without hosting them.
validatorUrl	By default, Swagger-UI attempts to validate specs against swagger.io's online validator. You can use this parameter to set a different validator URL, for example for locally deployed validators (Validator Badge). Setting it to `null` will disable validation.
dom_id	The id of a dom element inside which SwaggerUi will put the user interface for swagger.
domNode	The HTML DOM element inside which SwaggerUi will put the user interface for swagger. Overrides `dom_id`.
oauth2RedirectUrl	OAuth redirect URL
tagsSorter	Apply a sort to the tag list of each API. It can be 'alpha' (sort by paths alphanumerically) or a function (see Array.prototype.sort() to learn how to write a sort function). Two tag name strings are passed to the sorter for each pass. Default is the order determined by Swagger-UI.
operationsSorter	Apply a sort to the operation list of each API. It can be 'alpha' (sort by paths alphanumerically), 'method' (sort by HTTP method) or a function (see Array.prototype.sort() to know how sort function works). Default is the order returned by the server unchanged.
defaultModelRendering	Controls how models are shown when the API is first rendered. (The user can always switch the rendering for a given model by clicking the 'Model' and 'Example Value' links.) It can be set to 'model' or 'example', and the default is 'example'.
defaultModelExpandDepth	The default expansion depth for models. The default value is 1.
configUrl	Configs URL
parameterMacro	MUST be a function. Function to set default value to parameters. Accepts two arguments parameterMacro(operation, parameter). Operation and parameter are objects passed for context, both remain immutable
modelPropertyMacro	MUST be a function. Function to set default values to each property in model. Accepts one argument modelPropertyMacro(property), property is immutable
docExpansion	Controls the default expansion setting for the operations and tags. It can be 'list' (expands only the tags), 'full' (expands the tags and operations) or 'none' (expands nothing). The default is 'list'.
displayOperationId	Controls the display of operationId in operations list. The default is `false`.
displayRequestDuration	Controls the display of the request duration (in milliseconds) for `Try it out` requests. The default is `false`.
maxDisplayedTags	If set, limits the number of tagged operations displayed to at most this many. The default is to show all operations.
filter	If set, enables filtering. The top bar will show an edit box that you can use to filter the tagged operations that are shown. Can be true/false to enable or disable, or an explicit filter string in which case filtering will be enabled using that string as the filter expression. Filtering is case sensitive matching the filter expression anywhere inside the tag.
deepLinking	If set to `true`, enables dynamic deep linking for tags and operations. Docs
requestInterceptor	MUST be a function. Function to intercept try-it-out requests. Accepts one argument requestInterceptor(request) and must return the potentially modified request.
responseInterceptor	MUST be a function. Function to intercept try-it-out responses. Accepts one argument responseInterceptor(response) and must return the potentially modified response.
showMutatedRequest	If set to `true` (the default), uses the mutated request returned from a rquestInterceptor to produce the curl command in the UI, otherwise the request before the requestInterceptor was applied is used.

Plugins

Topbar plugin enables top bar with input for spec path and explore button or a dropdown if urls is used. By default the plugin is enabled, and to disable it you need to remove Topbar plugin from presets in src/standalone/index.js:, _(*23)

let preset = [
  // TopbarPlugin,
  ConfigsPlugin,
  () => {
    return {
      components: { StandaloneLayout }
    }
  }
]

Configs plugin

Configs plugin allows to fetch external configs instead of passing them to SwaggerUIBundle. Fetched configs support two formats: JSON or yaml. The plugin is enabled by default. There are three options of passing config: - add a query parameter config with URL to a server where the configs are hosted. For ex. http://petstore.swagger.io/?config=http://localhost:3001/config.yaml - add a config configUrl with URL to SwaggerUIBundle - change default configs in swagger-config.yaml Note: after changing, the project must be re-built, _(*24)

These options can be used altogether, the order of inheritance is following (from the lowest priority to the highest): swagger-config.yaml -> config passed to SwaggerUIBundle -> config fetched from configUrl passed to SwaggerUIBundle -> config fetched from URL passed as a query parameter config, _(*25)

CORS Support

CORS is a technique to prevent websites from doing bad things with your personal data. Most browsers + JavaScript toolkits not only support CORS but enforce it, which has implications for your API server which supports Swagger., _(*26)

You can read about CORS here: http://www.w3.org/TR/cors., _(*27)

There are two cases where no action is needed for CORS support:, _(*28)

swagger-ui is hosted on the same server as the application itself (same host and port).
The application is located behind a proxy that enables the required CORS headers. This may already be covered within your organization.

Otherwise, CORS support needs to be enabled for:, _(*29)

Your Swagger docs. For Swagger 2.0 it's the swagger.json/swagger.yaml and any externally $refed docs.
For the Try it now button to work, CORS needs to be enabled on your API endpoints as well.

Testing CORS Support

You can verify CORS support with one of three techniques:, _(*30)

Curl your API and inspect the headers. For instance:

$ curl -I "http://petstore.swagger.io/v2/swagger.json"
HTTP/1.1 200 OK
Date: Sat, 31 Jan 2015 23:05:44 GMT
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, POST, DELETE, PUT, PATCH, OPTIONS
Access-Control-Allow-Headers: Content-Type, api_key, Authorization
Content-Type: application/json
Content-Length: 0

This tells us that the petstore resource listing supports OPTIONS, and the following headers: Content-Type, api_key, Authorization., _(*31)

Try swagger-ui from your file system and look at the debug console. If CORS is not enabled, you'll see something like this:

XMLHttpRequest cannot load http://sad.server.com/v2/api-docs. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

Swagger-UI cannot easily show this error state., _(*32)

Using the http://www.test-cors.org website. Keep in mind this will show a successful result even if Access-Control-Allow-Headers is not available, which is still required for Swagger-UI to function properly.

Enabling CORS

The method of enabling CORS depends on the server and/or framework you use to host your application. http://enable-cors.org provides information on how to enable CORS in some common web servers., _(*33)

Other servers/frameworks may provide you information on how to enable it specifically in their use case., _(*34)

CORS and Header Parameters

Swagger lets you easily send headers as parameters to requests. The name of these headers MUST be supported in your CORS configuration as well. From our example above:, _(*35)

Access-Control-Allow-Headers: Content-Type, api_key, Authorization

Only headers with these names will be allowed to be sent by Swagger-UI., _(*36)
