This event is automatically fired when an app or component is initialized, prior to rendering.
Component-
<aura:component>
<aura:handler name=”init” value=”{!this}” action=”{!c.doInit}”/>
</aura:component>
jsController-
({
doInit: function(cmp) {
// Set the attribute value.
// You could also fire an event here instead.
alert(‘test’);
}
})
