How to organize producer/consumer in different modules?

I want to organize a producer of tasks in one module and consuming-workers in another module. So I need to create jobs in one place of code without waiting for their processing. And workers are waiting for new tasks to process them.

**producer.js**
`const queue = require(kue).createQueue()`
`queue.create('task').save()`
`// need to close connection. If queue.quit() or process.exit(0) — workers are not receiving their jobs`

**consumer.js**
`const queue = require(kue).createQueue()`
`queue.process('task', () => done())`

Start by examining producer.js and consumer.js together, focusing on queue creation, job saving, and connection shutdown. Reproduce the behavior with the producer and consumer in separate modules, then establish the expected connection lifecycle and confirm that jobs remain available to the worker after the producer exits.
