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>
