Folgendes sollte funktionieren:
var getShows = function () {
return new Promise(function (resolve, reject) {
usersdb.find(function (err, users) {
if (err) return console.error(err);
var task = function (user) {
return new Promise(/* ... */);
};
var actions = users.map(task);
Promise.all(actions).then(resolve, reject);
});
});
};
getShows().then(function (results) {
// Prints the result of each task as an array
console.log(results);
});
