browser-platform

browser-platform

This is a naive implementation of browser/platform detection in JavaScript.

It is exported as a CommonJS/Node-style module, the main exports is a function that is meant to be called by passing in the useragent.

// CommonJS/Node Import
var platform = require('browser-platform')(window.navigator.userAgent)

// Direct browser injection
var platform = getBrowserPlatform(window.navigator.userAgent);
document.documentElement.setAttribute('class', ['js'].concat(platform.classNames).join(' '))

When run client-side some features (namely touch) are detected from the environment if not easily determined from the useragent. Android and iOS assume touch.

You can use platform.classes.join(' ') as CSS classes to be added to the html element, which can help with platform specific quirks.

The base portable detection portion of the script originated with detectmobilebrowser.com's regular expression(s). The rest was written by me. This library is released under a permissive ISC license. It has been very useful for me, and at 2.3KB minified and gzipped, much smaller than most detection libraries.
