It works but its still calllback hell :-( The db connection gets reused
tho.
getApp: function(appid) {
this.useConnection( function(db, client) {
this.useCollection(db, 'authors', function(collection) {
this.useQuery(collection, {'apps.id':appid},
function(data) {
console.log(data);
}.bind(this));
}.bind(this));
}.bind(this));
}

The EasyMySQL npm eliminates these callbacks and uses a connection
pool, so it only opens a new connection when needed.

Thats how I originally did it, but when you need to do multiple
queries to the database you shoud open the connection once and reuse
it instead of opening it multiple times a session.

I agree, it seems entirely manageable.
One low-overhead option would be just to split that out into a
function, if it's used frequently:
function dbQuery(query, callback){
db.open(... fn() {
db.collection(.... fn() {
db.query(query, callback);
});
});
}
dbQuery("SELET * FROM blah", fn() {
// stuff you would have done in the inner-most part here
});

It doesn't look that bad to me.
