NodeJS + Node-MongoDB-native: sort objects in alphabet order

Question

I'm trying to sort objects in collection by "name" parameter in alphabetical order. Here's the code I'm using:

app.get('/companies', loadUser, function(req,res){
    db.collection("companies",function(err,collection){
            collection.find({}, { sort:[['name',-1]]},function(err, companies) {
                var companies_list = new Array();
                companies.each(function(err, company){
            ... 
            });
    })
});

I actually don't understand how exactly sort parameter works and what is -1. The official documentation didn't help me. Thanks!

Your code looks fine. I'd rather use

{ sort: [['name': 'desc']] }

because it's more explicit. Both methods work though.

When omitting the sort-direction:

{ sort: 'name'}

it sorts ascending.
