CURRENT-DEVICE


This module makes it easy to write conditional CSS _and/or_ JavaScript based on
device operating system (iOS, Android, Blackberry, Windows, MacOs, Firefox OS, MeeGo,
AppleTV, etc), orientation (Portrait vs. Landscape), and type (Tablet vs.
Mobile).

This module inserts CSS classes into the element.

#### iPhone



#### Android Tablet



#### Blackberry Tablet

$3

- iOS: iPhone, iPod, iPad
- Android: Phones & Tablets
- Blackberry: Phones & Tablets

$3

Just include the script. The script then updates the section with the
appropriate classes
based on the device's characteristics.

Installation

``sh
npm install current-device
`

And then import it:

`js
// using es modules
import device from "current-device";

// common.js
const device = require("current-device").default;
`

Or use script tags and globals.

`html

`

And then access it off the global like so:

`js
console.log("device.mobile() === %s", device.mobile());
`

The following tables map which CSS classes are added based on device and
orientation.

BlackBerry Phone	blackberry mobile
BlackBerry Tablet	blackberry tablet
Windows Phone	windows mobile
Windows Tablet	windows tablet
Firefox OS Phone	fxos mobile
Firefox OS Tablet	fxos tablet
MeeGo	meego

Television	television

#### Orientation CSS Class Names

This module _also_ includes support for conditional JavaScript, allowing you to
write checks on the following device characteristics:

#### Device JavaScript Methods

Device	JavaScript Method
Mobile	device.mobile()
Tablet	device.tablet()
Desktop	device.desktop()
iOS	device.ios()
iPad	device.ipad()
iPhone	device.iphone()
iPod	device.ipod()
Android	device.android()
Android Phone	device.androidPhone()
Android Tablet	device.androidTablet()
BlackBerry	device.blackberry()
BlackBerry Phone	device.blackberryPhone()
BlackBerry Tablet	device.blackberryTablet()
Windows	device.windows()
Windows Phone	device.windowsPhone()
Windows Tablet	device.windowsTablet()
Firefox OS	device.fxos()
Firefox OS Phone	device.fxosPhone()
Firefox OS Tablet	device.fxosTablet()
MeeGo	device.meego()
Television	device.television()

#### Orientation JavaScript Methods

Orientation	JavaScript Method
Landscape	device.landscape()
Portrait	device.portrait()

#### Orientation JavaScript Callback

`js
device.onChangeOrientation(newOrientation => {
console.log(New orientation is ${newOrientation});
});
`

$3

#### device.noConflict()

Run current-device in noConflict mode, returning the device variable to its
previous owner. Returns a reference to the device object.

`js
const currentDevice = device.noConflict();
`

$3

Access these properties on the device object to get the first match on that
attribute without looping through all of its getter methods.

JS Property	Returns
device.type	'mobile', 'tablet', 'desktop', or 'unknown'
device.orientation	'landscape', 'portrait', or 'unknown'
device.os	'ios', 'iphone', 'ipad', 'ipod', 'android', 'blackberry', 'windows', 'macos', 'fxos', 'meego', 'television', or 'unknown'

Environment detection has a high rate of misuse. Often times, folks will attempt
to work around browser feature support problems by checking for the affected
browser and doing something different in response. The preferred solution for
those kinds of problems, of course, is to check for the feature, not the browser
(ala Modernizr).

However, that common misuse of device detection doesn't mean it should never be
done. For example, current-device` could be employed to change the interface of
your web app such that it uses interaction patterns and UI elements common to
the device it's being presented on. Android devices might get a slightly
different treatment than Windows or iOS, for instance. Another valid use-case is
guiding users to different app stores depending on the device they're using.

In short, check for features when you need features, and check for the browser
when you need the browser.
