In today’s digital landscape, understanding your users’ environments is key to providing an exceptional user experience. This is where the ng-device-detector module comes into play. This Angular library allows you to easily detect the Operating System, Browser, and Device your application is running on, enabling dynamic adjustments to your app’s presentation layer. In this guide, we’ll walk through the steps to install, configure, and utilize ng-device-detector with user-friendly explanations and troubleshooting tips.

Installation

To kick things off, you’ll need to install ng-device-detector. You can accomplish this via npm or Bower:

• Using npm:

npm install ng-device-detector --save

• Using Bower:

bower install ng-device-detector --save

• For a direct script integration, add the following HTML tags to your project:

Setting Up Your Application

Next, you need to integrate ng-device-detector into your Angular application:

• In your main app module, add ng.deviceDetector to your dependencies:

angular.module('app', ['ng.deviceDetector']);

• Inject the DeviceDetector service into your controller:

angular.module('app').controller('Home', function($scope, deviceDetector) {
  // Awesome stuff
});

• To add classes based on detection, use the directive:

<div device-detector></div>

Custom Detectors

If you want to create specific detection capabilities beyond what’s available, you can set up custom detectors using the following code:

angular.module('app', ['ng.deviceDetector'])
  .config(['deviceDetectorProvider', function(deviceDetectorProvider) {
    deviceDetectorProvider.addCustom('Custom_UA_Entry', {
      and: ['bCustom_UA_Entry'],
      not: ['bChrome']
    });
  }])
  .controller('Home', function($scope, deviceDetector) {
    $scope.customUAEntry = deviceDetector.custom['Custom_UA_Entry'];
});

Understanding the deviceDetector Service

The deviceDetector service provides several useful properties:

• raw: Contains the raw values (internal use).
• os: Name of the current Operating System.
• browser: Name of the current Browser.
• device: Name of the current Device.
