Usage Browser

<script src="mobile-detect.js"></script>
<script>
    var md = new MobileDetect(window.navigator.userAgent);
    // ... see below
</script> 

Node.js / Express

var MobileDetect = require('mobile-detect'),
    md = new MobileDetect(req.headers['user-agent']);
// ... see below
General
var md = new MobileDetect(
    'Mozilla/5.0 (Linux; U; Android 4.0.3; en-in; SonyEricssonMT11i' +
    ' Build/4.1.A.0.562) AppleWebKit/534.30 (KHTML, like Gecko)' +
    ' Version/4.0 Mobile Safari/534.30');



// more typically we would instantiate with 'window.navigator.userAgent'
// as user-agent; this string literal is only for better understanding
 
console.log( md.mobile() );          // 'Sony'
console.log( md.phone() );           // 'Sony'
console.log( md.tablet() );          // null
console.log( md.userAgent() );       // 'Safari'
console.log( md.os() );              // 'AndroidOS'
console.log( md.is('iPhone') );      // false
console.log( md.is('bot') );         // false
console.log( md.version('Webkit') );         // 534.3
console.log( md.versionStr('Build') );       // '4.1.A.0.562'
console.log( md.match('playstation|xbox') ); // false
