When a callback is omitted from a method on a model relation that
supports promises, return that promise. This includes all the standard
DAO methods, as well as any user-defined methods that return promises.
e.g.:
mylist.todos.create({name: 'Item 1'}) // returns Promise
This API will use native ES6 promises if available. If not available,
or to force the use of another Promise library, you must assign the
global.Promise object.
e.g.:
global.Promise = require('bluebird')
Relations affected:
- BelongsTo
- HasOne
- HasMany
- HasManyThrough
- HasAndBelongsToMany
- ReferencesMany
- EmbedsOne
Exceptions:
The EmbedsMany relation has not been promisified, because most of the
methods return synchronous values.
The base relation getter method [e.g.: mylist.todos()] has not been
promisified, due to its default caching behavior.
New Methods:
- getAsync(condition, cb)
A new method "getAsync()" has been added to all relations except
EmbedsMany, which always fetches from the datasource rather than from
the cache. It takes an optional "where" condition (except for HasOne
and BelongsTo) and an optional callback. If the callback is omitted,
a Promise is returned.

LoopBack DataSource Juggler
LoopBack DataSource Juggler is an ORM that provides a common set of interfaces for interacting with databases, REST APIs, and other data sources. It was initially forked from JugglingDB.
For full documentation, see the official StrongLoop documentation: Connecting models to data sources
For information on creating data sources programmatically, see Advanced topics: data sources.
Installation
npm install loopback-datasource-juggler
Also install the appropriated connector, for example for mongodb:
npm install loopback-connector-mongodb
See StrongLoop Documentation for more information.
