API

var jobs = Jobs([options])

Create a new jobs instance. Options:

• concurrency: 1

jobs.concurrency=

Set the concurrency of the jobs.

var length = jobs.push([id], fn, [priority])

Push a job to be run.

• fn - currently jobs must be a thunk.
• id - a unique job id as a string. Defaults to a random string.
• priority: 0 - a priority as a number.

var result = yield jobs.await(event)

Await the result of an event. All job ids are emitted as events. There are additionally these events:

• drain - when there are no more jobs to run

jobs.prioritize(id, priority)

If a job by id exists, sets its priority to priority.
