彼ら
node.jsでは、mongolianまたはmongo-nativeはグループ機能をサポートしていませんか?
モンゴネイティブコード、
var mongodb = require('mongodb');
var Db = mongodb.Db;
var Server = mongodb.Server;
var db = new Db( "test", new Server( "localhost", 27017 ), { w:0 } );
db.collection( "user" ).group( {
key: { },
reduce: function ( curr, result ) { },
initial: { }
} );
結果、
/node/ex1/node_modules/mongodb/lib/mongodb/collection.js:1400
if(err != null) return callback(err);
^
TypeError: undefined is not a function

およびmongolignコード、
var Mongolian = require( "mongolian" );
var server = new Mongolian;
var db = server.db( "test" );
db.collection( "user" ).group( {
key: { },
reduce: function ( curr, result ) { },
initial: { }
} );
結果、
db.collection( "user" ).group( {
^
TypeError: Object Mongolian[mongo://localhost:27017]/assistor.user has no method 'group'
