How to implement adapter pattern inside a LoopBack connector

job-queue-adapters.js

var adapters = {
  redis: RedisJobQueue,
  foo: FooJobQueue,
  bar: BarJobQueue
};

function JobQueueConnector(settings) {
  this.DataAccessObject = adapters[settings.type];
}

// legacy api for jugglingdb compatibility
JobQueueConnector.initialize = function(dataSource, callback) {
  var connector = dataSource.connector = new JobQueueConnector(dataSource.settings);

  callback();
}

function RedisJobQueue() {

}

RedisJobQueue.scheduleJob = function (id, options) {
  // approximation
  require('magic-redis-module').put(id, serialize(options));
}

function BarJobQueue(id, options) {
}

BarJobQueue.scheduleJob = function (id, options) {
  require('bar-module').schedule(it, options);
}
// ----- end connector -----

// use with a model
var lb = require('loopback');
var Job = lb.Model.extend('job');

Job.attachTo(lb.createDataSource({connector: JobQueueConnector, type: 'redis'}));

// actual usage
Job.scheduleJob('some job', {...});

// add to app
app.model(Job);

// use over rest
POST /jobs
{...options...}
