Snifferjs NPM | npm.io

Sniffer

Sniffer is a browser/engine/os/device detection tool. Works both in a browser and with Node.

Live demo (tests your browser UA string)

You have three options:

1. Default Sniffer build

Get sniffer.js from dist/. Drop the script tag in the <head>:

<script src="path/to/sniffer.js"></script>

It will run automatically, collect the information on current device/os/browser and put the results in window.Sniff object (or expose it via module.exports, if available). See “Detection results” for details. Now you can do horrible things:

if (Sniff.os.name=='android' &&
	Sniff.os.majorVersion &&
	Sniff.os.majorVersion < 3 &&
	!Sniff.browser.name &&
	Sniff.browser.engine=='webkit') {
		//looks like default Android 2.x browser!
		myMagicOverflowScrollPolyfill();
}

It will also add browser name shortcode, browser engine shortcode, OS name shortcode and device features’ shortcodes to <html> tag’s className, so you can alter the styles accordingly (pretty much the Modernizr way):

/* contrast colors for monochrome devices */
html.bw body {
	color: black;
	background: white;
}

/* make sure code snippets are readable in Opera Mini */
html.operamini pre code {
	white-space: pre-wrap;
}

2. Sniffer module

Get sniffer.module.js from dist/. It exposes Sniffer function into global scope or via module.exports, if available. Compatible with Node. Just feed it a user agent string:

Sniffer(userAgent);

It will return detection result, see “Detection results” for details.

Also available via npm: npm install snifferjs.

3. Pure Sniffer function

Get sniffer.pure.js from dist/. It contains pure Sniffer function (no wrap, no autolaunch, no css classes, no exports), you decide how to use it.

Detection results

Sniffer returns an object which looks like this:

{
	browser: {
		fullName: String, // full human readable name
		name: String, // shortcode
		version: String, // semantic version, up to three parts (major.minor.patch)
		majorVersion: Number,
		minorVersion: Number,
		patchVersion: Number,
		engine: String // shortcode
	},
	os: {
		fullName: String, // full human readable name
		name: String, // shortcode
		version: String, // semantic version, up to three parts (major.minor.patch)
		versionName: String, // human readable version name, e.g. 'Vista', 'Mavericks', etc.
		versionAltNames: Array, // possible alternatives, e.g. Windows NT 5.2 can be 'XP' or 'Server 2003'
		majorVersion: Number,
		minorVersion: Number,
		patchVersion: Number
	},
	features: {
		bw: Boolean, /* black and white (e-book readers) */
		mobile: Boolean, /* includes phones, tablets, e-book readers, portable game consoles, etc. */
		tv: Boolean, /* smart tv */
		proxy: Boolean /* serverside js & rendering, like in Opera Mini */
	}
}
