cfs-server-aggregation

Very simple implementation of some of server-side mongodb aggregation framework functions for cfs-collections Meteor.

cfs-server-aggregation is a fork of meteor-mongo-server which is a fork of mongodb-aggregation

This version is just converted from zvictors coffescript version to javascript and was altered, so it works on FS.Collections.

It extends FS.Collection with 3 methods so far, mapReduce, distinct and aggregate, so that you can do:

var col, result;

col = new Meteor.Collection("name");

if (Meteor.isServer) {
  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
  }, function(err, res) {
    return console.dir(res.stats);
  });
  result = col.distinct("Field Name");
  console.dir(result);
  result = col.aggregate(pipeline);
  console.dir(result);
}

To install it, run:

$ meteor add phosphoros:cfs-server-aggregation
