如何使用Angular JS在流星中使用Mongo DB聚合函数？

Question

I want know how to use mongo db aggregate function in meteor with angular.

I added the below packages:

meteor add meteorhacks:aggregate
meteor add monbro:mongodb-mapreduce-aggregation

In angular service, I wrote the code like this,

function getProductDetailsForCompare (skus) {

          return $meteor.collection( function() {
               return Products.aggregate([{ $match: {$or: [{"sku":"777160-001"},{"sku":"777161-001"},{"sku":"728350-B21"}]}}, {$group : {_id : "$sku", price : {$min : "$price"}}}]);
          });               
     }; 

When i run this code , giving the below exception.

TypeError: Products.aggregate is not a function

Do i need to do any additional setup? Do i need to add plugin in app.js?

It works only server side. write server side method to calculate aggregate in meteor.
