-
- ## New!
-
- This is the new version of swagger-ui, 3.x.
-
- For the older version of swagger-ui, refer to the [*2.x branch*](https://github.com/swagger-api/swagger-ui/tree/2.x).
-
- ## Compatibility
- The OpenAPI Specification has undergone 4 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.
-
- ##### Prerequisites
- - Node 6.x
- - NPM 3.x
-
- If you just want to see your specs, open `public/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`.
-
-
- ##### Browser support
- Swagger UI works in the latest versions of Chrome, Safari, Firefox, Edge and IE11.
-
- ## 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:
-
- 1. swagger-ui is hosted on the same server as the application itself (same host *and* port).
- 2. 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:
-
- 1. Your Swagger docs. For Swagger 2.0 it's the `swagger.json`/`swagger.yaml` and any externally `$ref`ed docs.
- 2. 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:
-
- ```bash
- $ 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.
