Introduction

Swagger UI is an interactive API documentation tool that allows developers and consumers to visualize, test, and interact with API resources without needing backend implementation knowledge. It is automatically generated from your OpenAPI specification and simplifies API exploration, debugging, and onboarding.

🕰️ Looking for the older version of Swagger UI? Refer to the 2.x branch.

This repository publishes three different NPM modules:

| Module | Use Case |

• swagger-ui is a traditional npm module intended for use in single-page applications 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 single-page application that can't resolve npm module dependencies.
• swagger-ui-react is Swagger UI packaged as a React component for use in React applications.

We strongly suggest that you use swagger-ui instead of swagger-ui-dist if you're building a single-page application, since swagger-ui-dist is significantly larger.

If you are looking for plain ol' HTML/JS/CSS, download the latest release and copy the contents of the /dist folder to your server.

Anonymized analytics

SwaggerUI uses Scarf to collect anonymized installation analytics.

These analytics help support the maintainers of this library and ONLY run during installation.

To opt out, you can set the scarfSettings.enabled field to false in your project's package.json:

// package.json
{
  // ...
  "scarfSettings": {
    "enabled": false
  }
  // ...
}

Alternatively, you can set the environment variable SCARF_ANALYTICS to false as part of the environment that installs your npm packages, e.g., SCARF_ANALYTICS=false npm install.
