## Installation

This package can be installed from **[NPM](https://www.npmjs.com/package/@simplewebauthn/browser)**
and **[JSR](https://jsr.io/@simplewebauthn/browser)**:

### Node LTS 22.x and higher

```sh
npm install @simplewebauthn/browser
```

> NOTE: This project will aim to support Node LTS releases through their Active and Maintenance windows as tracked on [the Node.js Releases page](https://nodejs.org/en/about/previous-releases).

### Deno v2.4.x and higher

```sh
deno add jsr:@simplewebauthn/browser
```

> NOTE: [Deno no longer has LTS releases to track after April 30, 2026](https://docs.deno.com/runtime/fundamentals/stability_and_releases/#long-term-support-(lts)). This project will aim to support Deno minor releases for up to one year after their release.

### UMD

This package can also be installed via **unpkg** by including the following script in your page's
`<head>` element. The library's methods will be available on the global **`SimpleWebAuthnBrowser`**
object.

> NOTE: The only difference between the two packages below is that the ES5 bundle includes some
> polyfills for older browsers. This adds some bundle size overhead, but _does_ enable use of
> `browserSupportsWebAuthn()` in older browsers to show appropriate UI when WebAuthn is unavailable.

#### ES2021

If you only need to support modern browsers, include the `ES2021` version:

```html
<script src="https://unpkg.com/@simplewebauthn/browser/dist/bundle/index.umd.min.js"></script>
```

#### ES5

If you need to support WebAuthn feature detection in deprecated browsers like IE11 and Edge Legacy,
include the `ES5` version:

```html
<script src="https://unpkg.com/@simplewebauthn/browser/dist/bundle/index.es5.umd.min.js"></script>
```
