Aura Component Attributes Simplified
Aura attributes are like variables in Apex which stores certain data types.
Let’s understand the Attributes Types with a game of cricket 🙂
Boolean
It stores either True or False.
<aura:attribute name="isCricketMatchToday" type="Boolean" />Date
It stores a date value that corresponds to a calendar day in the format yyyy-mm-dd.
<aura:attribute name="finalsDate" type="Date" />DateTime
It stores a DateTime value. It corresponds to a timestamp.
<aura:attribute name="matchTimings" type="DateTime" />Double
It stores a decimal number(A number with a decimal point).
<aura:attribute name="runRate" type="Double" />Decimal
It also stores a decimal number. It is better than double for maintaining precision and is a preferred type for storing currency values.
<aura:attribute name="ticketsEarnings" type="Decimal" />Integer
It stores a number without any decimal point.
<aura:attribute name="matchScore" type="Integer" />Long
It stores a number without any decimal point. This type can store more values than Integer can hold.
<aura:attribute name="ticketSold" type="Long" />String
It stores a sequence of characters.
<aura:attribute name="currentBatsman" type="String" />Below we cover the non-Basic Types of attributes:
Id
It stores the salesforce record Id.
<aura:attribute name="currentBatsmanRecordId" type="Id" />Arrays
It stores an array of common Types.
<aura:attribute name="OpeningBatsman" type="String[]"/>Object
It can store any other basic type or a type that is an instance of an Object.
<aura:attribute name="matchStats" type="Object" />sObject
It stores sObject data either a standard object or a custom object.
Below we have declared an attribute holding a custom object Player__c.
<aura:attribute name="playerData" type="Player__c"/>Here we covered the attributes and what type of values they can store.
You should be aware of how to use them in Aura Component by setting and getting their values.
