how to use aggregate function in meteor

Question

I\'m working on the following document

{
\"_id\" : 12,
\"firstName\" : \"wer\",
\"People\" : [ 
    {
        \"uuid\" : \"123\",
        \"name\" : \"sugun\         


        

Answer 1

Here is what I tried manually and worked for me:

var rawUsers = Meteor.users.rawCollection();
var aggregateQuery = Meteor.wrapAsync(rawUsers.aggregate, rawUsers);
var pipeline = [
    {$match: {}},
    {$project: {username: 1, profile: 1}}
];
var result = aggregateQuery(pipeline);

return result;
