How to display Aura JS Errors Lightning Out
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I know I can wrap in a try / catch but the goal here is to display a useful error in cases where one was not expected..(programming error)
A basic lightning component displayed in a VF page using the standard app and component.
The only thing on the component is a lightning:spinner. The component has an init handler and the sole job of the init JS is to hide the spinner.
<aura:component description="test">
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
<lightning:spinner variant="brand" aura:id="test_spinner"/>
</aura:component>
The controller
({
doInit : function(component,event,helper){
console.log('init');
helper.donothing(); //This does not exist and causes an error
$A.util.addClass(component.find("test_spinner"),'slds-hide');
}
})
Now when this runs it causes a framework error. The problem is that the user sees nothing. The spinner does not get hidden and the page just stalls...
Is there any way to display a message to the user instead of the entire component just stalling?
For some reason I seem to recall a component that could be used to display framework errors but I cannot seem to find it or I am just remembering incorrectly

There is a display element; it shows up at the very bottom of the page. This happens in Lightning Out automatically. It's not styled by default, as far as I can tell, so you might want to add some style to it. The message is in a div#auraErrorMessage element. Try starting with this:
<style>
div#auraErrorMessage {
position: fixed;
text-align: center;
white-space: pre-line;
padding-top: calc(25vh - 3em);
height: 50vh;
top: 25vh;
left: 25vw;
right: 25vw;
z-index: 1000;
border: 5px solid red;
}
</style>
You could attach a DOM mutation event to this element to detect new messages, etc as well.
I'm not aware of a specific way to otherwise handle errors in Lightning Out; this is normally handled by the App (e.g. one.app), but it's not documented how/if we can do this externally.
