Generate a hyperlink to a recordId in a Lightning Aura Component

The lightning:formattedUrl component renders a hyperlink with an href attribute, presenting a read-only representation of a URL. The URL can be either relative or absolute.

Code Example:

<aura:component> 
    <aura:attribute name="recordId" type="String" default="0063X0000146rTLQAY"/>
    <lightning:formattedUrl value="{!'/' + recordId}" tooltip="Opportunity" label="Opportunity" target="_blank" />
</aura:component>
