Package Exports
- await-to-js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (await-to-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Pre-requisites
You need ES7 transpiler in order to use async/await functionality. You can use babel or typescript for that.

const [ err, savedTask ] = await to(TaskModel({userId: user.id, name: 'Demo Task'}));
if(err) return cb('Error occurred while saving task');

const [ err ] = await to(NotificationService.sendNotification(user.id, 'Task Created'));
