Very simple implementation of some of mongodb aggregation framework functions for Meteor.
Mongodb-server-aggregation is a fork of mongodb-aggregation that do not expose the aggregation framework to the client, being available only on server side.
It extends Collection with 3 methods so far, mapReduce, distinct and aggregate, so that you can do:
col = new Meteor.Collection "name"
if Meteor.isServer
# mapReduce
map = function() {emit(this.Region, this.Amount);}
reduce = function(reg, am) { return Array.sum(am);};
col.mapReduce map, reduce, {out: "out_collection_name", verbose: true}, (err,res)->
console.dir res.stats # statistics object for running mapReduce
# distinct
result = col.distinct "Field Name"
console.dir result
#aggregate
result = col.aggregate pipeline
console.dir resultTo install it, run:
