The proper way to do this (i think) is to pass a function as the last
parameter of your find function, then when you have the response from
Mongo, call that function and pass the results to it, along with any
possible error.
function list(callback) {
var serverMongo = new mongodb.Server("127.0.0.1", 27017, {});
new mongodb.Db('mytestnode', serverMongo, {}).open(function (error,
client) {
if (error) throw error;
var collection = new
mongodb.Collection(client, 'mytestcollection');
collection.find().toArray( function (err, objects) {
if (err) {
console.warn(err.message);
callback(err, objects);
} else {
console.log(objects);
callback(null, objects);
}
serverMongo.close();
});
});
}
