In Apex we can do


In Visualforce we can do


Is there any equivalent way to access easily from a Lightning component's helper.js?

I tried the following, which I'd think would work, but is returning "undefined" when it's definitely true:


    public Boolean isBigDataMode {
      get {
          if (isBigDataMode == null) {
              isBigDataMode = Product_Pricing_Settings__c.getInstance().Use_Big_Data_Mode__c == true;
          return isBigDataMode;


    <aura:attribute name="isBigDataMode" type="Boolean" default="{!isBigDataMode}"/>


    getBigDataMode : function(component){
      console.log("big data: "+component.get("v.isBigDataMode"));
      return component.get("v.isBigDataMode");

This is returning to the console

big data: undefined


I would recommend the same as prashanthkr, this code should work:

JS Controller:

    var action = component.get("c.getHiearchySettings");

    action.setCallback(this, function(response){
        if(component.isValid() && response !== null && response.getState() == 'SUCCESS'){
            //saving custom setting to attribute
            component.set("v.settings", response);
            console.debug(response.Use_Big_Data_Mode__c );//Check the output
            //... rest of your code


Apex Controller:

public class MyController{
    public static MyHiearchy__c getHiearchySettings(){
        return MyHiearchy__c.getInstance();

    Not sure if the API changed, but I think it's supposed to be response.getReturnValue().Use_Big_Data_Mode__c – JDB still remembers Monica May 14 '18 at 19:56

    Instead of component.set("v.settings", response); I would recommend component.set("v.settings", response.getReturnValue(); – Mike Paisner Dec 31 '18 at 23:22

You would have to create an @AuraEnabled action method that returns the value of isBigDataMode to the component. You can find more details here

    Tried that, wasn't able to get it working. Have a code snippet sample? – Ray Dehler Jul 20 '16 at 1:59
