Recommended method for chaining

[HarikalarKutusu]

Great library, thanks! I found it yesterday and it is up and running with whistles... The only two culprits I could find were the path manipulation for jobs and the limitations of worker stuff from Node...

I'm writing a microservice and it has many jobs to be ported to bree. Many of these depend on successfull execution of previous jobs. I need to chain them (I was thinking Promises before Bree). This deals with datasets for AI. For the sake of an example:

=> download_job_1
  => extract_job_1
      => aggregate_job_11
            => publish_job_11
      => aggregate_job_12
            => publish_job_12
=> download_job_2
...

I know about bree.on("worker deleted", name), I can check what is finished and act accordingly to schedule follow-up jobs, but it will be a large structure. Is there any other way, any other idea such as signaling etc?

Thank you for the answers.
