app.get('/api/powders', function(req, res, next) {   db.collection('powders').find({} ,{limit:0, sort: [['_id',-1]]}).toarray(function(e, results){     if (e) return next(e)     res.send(results)   }) })

use db.command().

db.command( { distinct: "powders", key: "color" }, function( err, result ) {     // ... });
