README
New!
This is the new version of swagger-ui, 3.x. Want to learn more? Check out our FAQ.
👉🏼 Want to score an easy open-source contribution? Check out our Good first issue label.
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.
This repository publishes to two different NPM modules:
- 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.
Compatibility
The OpenAPI Specification has undergone 5 revisions since initial creation in 2010. Compatibility between swagger-ui and the OpenAPI Specification is as follows:
How to run
Easy start! Docker
You can pull a pre-built docker image of the swagger-ui directly from Dockerhub:
docker pull swaggerapi/swagger-ui
docker run -p 80:8080 swaggerapi/swagger-ui
Will start nginx with swagger-ui on port 80.
Or you can provide your own swagger.json on your host
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.
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
.
If you'd like to rebuild the /dist
folder with your codebase changes, run npm run build
.
Integration Tests
You will need JDK of version 7 or higher as instructed here http://nightwatchjs.org/gettingstarted#selenium-server-setup
Integration tests can be run locally with npm run e2e
- be sure you aren't running a dev server when testing!
Browser support
Swagger UI works in the latest versions of Chrome, Safari, Firefox, Edge and IE11.
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.
- 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.
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:
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
.
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.
Parameters
Parameters with dots in their names are single strings used to organize subordinate parameters, and are not indicative of a nested structure.
Plugins
Topbar plugin
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
:
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
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
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.
You can read about CORS here: http://www.w3.org/TR/cors.
There are two cases where no action is needed for CORS support:
- 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:
- Your Swagger docs. For Swagger 2.0 it's the
swagger.json
/swagger.yaml
and any externally$ref
ed 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:
- 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
.
- 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.
- 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.
Other servers/frameworks may provide you information on how to enable it specifically in their use case.
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:
Access-Control-Allow-Headers: Content-Type, api_key, Authorization
Only headers with these names will be allowed to be sent by Swagger-UI.
