What's Covered

51Degrees device detector returns all detection results as a string. This tutorial demonstrates how to return results for the IsMobile property value as a boolean.

Code and Explanation

Getting started example of using 51Degrees device detection. The example shows how to:
  1. Set the configuration using a json object

    var config = {"dataFile" : require("fiftyonedegreeslitepattern"),
                  "properties" : "IsMobile",
                  "stronglyTyped" : true
    };
    

    Note: stronglyTyped does not need to be set explicitly as true is the default

  2. Instantiate the 51Degrees device detection provider with this connfiguration

    var provider = new fiftyonedegrees.provider(config);
    

  3. Produce a match for a single HTTP User-Agent header

    var match = provider.getMatch(userAgent);
    

  4. Extract the value of the IsMobile property as boolean

    match.IsMobile;

var fiftyonedegrees = require("fiftyonedegreescore");

// Set the config.
var config = {"dataFile" : require("fiftyonedegreeslitepattern"),

              "stronglyTyped" : true
             };

var provider = new fiftyonedegrees.provider(config);

// User-Agent string of an iPhone mobile device.
var mobileUserAgent = ("Mozilla/5.0 (iPhone; CPU iPhone OS 7_1 like Mac OS X" +
") AppleWebKit/537.51.2 (KHTML, like Gecko) 'Version/7.0 Mobile/11D167 " +
"Safari/9537.53")

// User-Agent string of Firefox Web browser version 41 on desktop.
var desktopUserAgent = ("Mozilla/5.0 (Windows NT 6.3; WOW64; rv:41.0) " +
"Gecko/20100101 Firefox/41.0")
// User-Agent string of a MediaHub device.

"Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 " +
"Chrome/30.0.0.0 Safari/537.36")

console.log('Unlike other examples, stronglyTyped is set to \'true\' ' +
            'in the config. This is the default if not set.\n');

console.log('Mobile User-Agent: ' + mobileUserAgent)

// Determines whether the mobile User-Agent is a mobile device.
var match = provider.getMatch(mobileUserAgent);
if (match.IsMobile){
    console.log('   Mobile\n');
} else {
    console.log('   Non-Mobile\n');
}
match.close();

console.log('Desktop User-Agent: ' + desktopUserAgent)

// Determines whether the desktop User-Agent is a mobile device.
var match = provider.getMatch(desktopUserAgent);
if (match.IsMobile){
    console.log('   Mobile\n');
} else {
    console.log('   Non-Mobile\n');
}
match.close();

console.log('MediaHub User-Agent: ' + mediaHubUserAgent)

// Determines whether the MediaHub User-Agent is a mobile device.
var match = provider.getMatch(mediaHubUserAgent);
if (match.IsMobile){
    console.log('   Mobile\n');
} else {
    console.log('   Non-Mobile\n');
}
match.close();

Summary

In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined User-Agent string. It sets a boolean value to true or false from the original string value of "True" or "False", making if statements simpler to test.
