Swagger Client

Build Status

Swagger Client is a JavaScript module that allows you to fetch, resolve, and interact with Swagger/OpenAPI documents.


This is the new version of swagger-js, 3.x. The new version supports Swagger 2.0 as well as OpenAPI 3.

For features known to be missing from 3.x please see the Graveyard.

For the older version of swagger-js, refer to the 2.x branch.

The npm package is called swagger-client and the GitHub repository is swagger-js. We'll be consolidating that soon. Just giving you the heads up. You may see references to both names.


The OpenAPI Specification has undergone multiple revisions since initial creation in 2010. Compatibility between Swagger Client and the OpenAPI Specification is as follows:
