$Browser

The $Browser global value provider returns information about the hardware and operating system of the browser accessing the application.

Attribute	Description
`formFactor`	Returns a `FormFactor` enum value based on the type of hardware the browser is running on. DESKTOP for a desktop client PHONE for a phone including a mobile phone with a browser and a smartphone TABLET for a tablet client (for which `isTablet` returns `true`)
`isAndroid`	Indicates whether the browser is running on an Android device (`true`) or not (`false`).
`isIOS`	Not available in all implementations. Indicates whether the browser is running on an iOS device (`true`) or not (`false`).
`isIPad`	Not available in all implementations. Indicates whether the browser is running on an iPad (`true`) or not (`false`).

Example

This example shows usage of the $Browser global value provider.

1<aura:component>
2    {!$Browser.isTablet}
3    {!$Browser.isPhone}
4    {!$Browser.isAndroid}
5    {!$Browser.formFactor}
6</aura:component>

Similarly, you can check browser information in a client-side controller using $A.get().

1({
2    checkBrowser: function(component) {
3        var device = $A.get("$Browser.formFactor");
4        alert("You are using a " + device);
5    }
6})
