HOW TO USE VALUE PROVIDERS IN SALESFORCE LIGHTNING ?

VALUE PROVIDERS

In this episode, we have something different to discuss i.e. salesforce lightning value providers.
Let's get started, So value providers are a way to access data.

Value providers encapsulate related value together, similar to how an object encapsulates properties and methods.
The value providers for a component are v(view) and c(controller).

A component's view refers to its attribute set.

A component's controller enables you to wire up event handlers and action for the components. It's where you control your component's logic.

All components have value providers but aren't required to have a controller. Both value providers are created automatically when defined for a component.
In simple words, the salesforce value provider provides information about your browser, location, your device information etc.

Let's understand global value providers.
Global Value Providers :
Global value providers are value and methods that a component can use in the lightning expression.

Here are some global value providers you need to know :

globalId:
It returns the global ID for a component has a unique globalId, which is generated runtime-unique ID of the component instance.

$Browser: It returns information about the hardware and operating system of the browser accessing the application.

$Label: It enables you to access labels stored outside your code.

$Locale: It returns information about the current user's preferred locale.
Now we are more interested to discuss $Browser and $Locale.
So let's see attributes of $Browser :

isAndroid:
It indicates whether the browser is running on an Android device (true) or not (false).

isIOS: It is not available in all implementations. It indicates whether the browser is running on an iOS device (true) or not (false).

isIPhone: It indicates whether the browser is running on the iPhone (true) or not (false).

isWindowsPhone: It indicates whether the browser is running on a windows phone (true) or not (false).
FORM FACTOR ATTRIBUTE :
It returns a Form Factor enum value based on the type of hardware the browser is running on

DESKTOP for a desktop client

PHONE for the phone including a mobile phone with a browser and a          smartphone

TABLET for a tablet client (for which isTablet returns True)
Let's Understand with an example :
Example Lightning Component :
=================================================
<aura:component>
  Browser running on Tablet: {!$Browser.isTablet}
   <br></br>
    Is it running on IPhone: {!$Browser.isIPhone}
    <br></br>
     Is it running on Android: {!$Browser.isAndroid}
     <br></br>
I am Running on : {!$Browser.FormFactor}
</aura:component>
=================================================

Output :
=================================================
Browser running on Tablet: false
Is it running on IPhone: false
Is it running on Android: false
I am Running on DESKTOP
=================================================


Now we have attributes of $Locale global value providers.

$Locale: 
The $Locale global value provider returns information about the current user's preferred locale.

Country: The ISO 3166 representation of the country code based on the language locale.

Currency: The currency symbol.

Timezone: The time zone ID.

NumberFormat: Gives number formatting.
Let's understand with an example :
Example Lightning Component :
=================================================
<aura:component>
  Language : {!$Locale.language}
   <br></br>
   TimeZone : {!$Locale.timezone}
     <br></br>
      Number Format : {!$Locale.NumberFormat}
       <br></br>
        Currency : {!$Locale.Currency}
        <br></br>
</aura:component>
=================================================

Output:

=================================================
Language : en

TimeZone : America / Los-Angeles
Number Format : #, ##0, ###
Currency : $
=================================================
