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

## New!

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

Want to learn more? Check out our [FAQ](docs/migration/migration-2-x-to-3-x.md).

For features known to be missing from 3.x please see the [Graveyard](docs/migration/graveyard-3-x.md).


For the older version of swagger-js, refer to the [*2.x branch*](https://github.com/swagger-api/swagger-js/tree/2.x).

> *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.*

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

Swagger Client Version | Release Date | OpenAPI Spec compatibility                    | Notes
------------------ |--------------|-----------------------------------------------| -----
3.33.x | 2024-12-30   | 2.0, 3.0.0, 3.0.1, 3.0.2, 3.0.3, 3.0.4, 3.1.0 | [tag v3.33.0](https://github.com/swagger-api/swagger-js/releases/tag/v3.33.0)
3.19.x | 2023-01-23   | 2.0, 3.0.0, 3.0.1, 3.0.2, 3.0.3, 3.1.0        | [tag v3.19.0-alpha.3](https://github.com/swagger-api/swagger-js/releases/tag/v3.19.0-alpha.3)
3.10.x | 2020-01-17   | 2.0, 3.0.0, 3.0.1, 3.0.2, 3.0.3               | [tag v3.10.0](https://github.com/swagger-api/swagger-js/tree/v3.10.0)
2.1.32 | 2017-01-12   | 1.0, 1.1, 1.2                                 | [tag v2.1.32](https://github.com/swagger-api/swagger-js/tree/v2.1.32). This [release](https://github.com/swagger-api/swagger-js/releases/tag/v2.1.32) is only available on GitHub.

## Anonymized analytics

Swagger Client uses [Scarf](https://scarf.sh/) to collect [anonymized installation analytics](https://github.com/scarf-sh/scarf-js?tab=readme-ov-file#as-a-user-of-a-package-using-scarf-js-what-information-does-scarf-js-send-about-me). These analytics help support the maintainers of this library and ONLY run during installation. To [opt out](https://github.com/scarf-sh/scarf-js?tab=readme-ov-file#as-a-user-of-a-package-using-scarf-js-how-can-i-opt-out-of-analytics), 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`.

### Runtime 

### Node.js

`swagger-client` requires Node.js `>=12.20.0` and uses different `fetch` implementation depending
on Node.js version.

- `>=12.20.0 <18` - [node-fetch@3](https://www.npmjs.com/package/node-fetch) 
- `>=18` - [native Node.js fetch](https://nodejs.org/dist/latest-v18.x/docs/api/globals.html#fetch)

> NOTE: swagger-client minimum Node.js runtime version aligns with [Node.js Releases](https://nodejs.org/en/about/releases/)
> which means that we can drop support for **EOL** (End Of Life) Node.js versions without doing major version bump.

### Browsers

`swagger-client` works in the latest versions of Chrome, Safari, Firefox, and Edge
and uses [native fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) implementation
provided by each supported browser.
