Uncaught ReferenceError: ReactiveVar is not defined

I’m fairly new to meteor’s framework and I have been stuck on this issue trying to define a ReactVar in my templates onCreated function. I’m trying to return the template instance in my templates helper but javascript is complaining about an Uncaught ReferenceError: ReactiveVar is not defined.

here what the code looks like:

Template.someDetails.onCreated(function (){
var self = this;
self.details = new ReactiveVar();
Meteor.call(‘findSomeDetails’, function (err, asyncValue) {
if (err)


details: function () {
return Template.instance().self.details.get();

one thing to note is that this template is loaded within another template which I do not have a js file for. I only created a js file for the child template. Not sure if this could have something to do with it.

You need to meteor add reactive-var.

It did come prepackaged with the version of meteor I have installed so I did not need to install it. Should I remove it and install again?

Can you share the output of meteor list?

Yeah thats the cause of the exception. I did not have reactive-var in my package list. I don’t know why I thought I did. Newbie mistake! I know now to double check meteor list. Thanks for all your help.
