Minimal asynchronous task solving queue with zero dependences

Task-Queue

Minimal asynchronous tasks solving queue with zero dependences

Usage

$> npm install https://github.com/adefrutoscasado/task-queue

// app.js
import TaskQueue from 'task-queue'

const updateDatabase = async id => {
  const startTime = new Date()
  await randomDelay()
  const endTime = new Date()
  console.log(
    `update ${id}@${startTime.toISOString()} finished@${endTime.toISOString()}`
  )
  return { id }
}

const taskQueue = new TaskQueue()

taskQueue.enqueue(() => updateDatabase(1)) // returns {id: 1}
taskQueue.enqueue(() => updateDatabase(2)) // returns {id: 2}

The tasks are always solved on a first-come, first-served basis and never solved simultaneously:
