Browser/engine/os/device detection tool
npm install snifferjsjs
`
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:
`js
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 tag’s className, so you can alter the styles accordingly (pretty much the Modernizr way):
`css
/ 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;
}
`
$3
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:
`js
Sniffer(userAgent);
`
It will return detection result, see “Detection results” for details.
Also available via npm: npm install snifferjs.
$3
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:
`js
{
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) /
