Jobs require a manual factory

[drauschenbach]

Normally jobs in an Express app require some sort of access to the application object, where locals hold references to db & redis adapters, and configuration.

The current klass_finder.js architecture seems to prevent me from writing a job handler that has access to the current application context.

Injecting my own klassFinder into a worker might be one way for me to control construction of the job class handlers, so that I can pass the app context.

Possible work-around:

// app.js
let client = new qless.Client(redisUrl)
client.app = myExpressApp

// jobs/myJob.js
module.exports = {
  perform(job, cb) {
    job.client.app.locals.db.store(..., cb)
  }
}
