Example

<script type="text/javascript" src="ua-parser.js"></script>
<script type="text/javascript">
    
	var parser = new UAParser();
	
    // by default it takes ua string from current browser's window.navigator.userAgent
    console.log(parser.getResult());
    /*
        /// this will print an object structured like this:
        {
            browser: {
                name: "",
                version: "",
                major: ""
            },
            engine: {
                name: "",
                version: ""
            },
            os: {
                name: "",
                version: ""
            },
            device: {
                model: "",
                type: "",
                vendor: ""
            }
        }
    */

    // let's test a custom user-agent string as an example
    var uastr = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.2 (KHTML, like Gecko) Ubuntu/11.10 Chromium/15.0.874.106 Chrome/15.0.874.106 Safari/535.2";
    parser.setUA(uastr);
    
    console.log(parser.getResult().browser);    // {name: "Chromium", major: "15", version: "15.0.874.106"}
    console.log(parser.getResult().device);     // {model: undefined, type: undefined, vendor: undefined}
    console.log(parser.getResult().engine);     // {name: "AppleWebKit", version: "535.2"}
    console.log(parser.getResult().os);         // {name: "Ubuntu", version: "11.10"}
    
    // let's take another test please
    console.log(parser.setUA("Mozilla/5.0 (compatible; Konqueror/4.1; OpenBSD) KHTML/4.1.4 (like Gecko)").getBrowser().name); // "Konqueror"
    console.log(parser.getOS());                // {name: "OpenBSD", version: undefined}
    console.log(parser.getEngine());            // {name: "KHTML", version: "4.1.4"}
</script>

Using node.js

var UAParser    = require('ua-parser');
var parser      = new UAParser();
var uaString    = 'Mozilla/5.0 (PlayBook; U; RIM Tablet OS 1.0.0; en-US) AppleWebKit/534.11 (KHTML, like Gecko) Version/7.1.0.7 Safari/534.11';

console.log(parser.setUA(uaString).getDevice().model);  // "PlayBook"
console.log(parser.getOS())                             // {name: "RIM Tablet OS", version: "1.0.0"}
console.log(parser.getEngine().name);                   // "AppleWebKit"
