Swagger UI

New!

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

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:

Swagger UI Version	Release Date	OpenAPI Spec compatibility	Notes
3.6.0	2017-12-01	2.0, 3.0	tag v3.5=6.0
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

1.0.1	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:

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

The base URL of the web application can be changed by specifying the BASE_URL environment variable:

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

This will serve Swagger UI at /swagger instead of /.

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"
    })

If you’d like to use the bundle files via npm, check out the swagger-ui-dist package.

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
