    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.


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