Describtion

You can add your async task to promise queue in dynamic .
It's easy and effective .

For example:

1. normal promise task queue

    let PromiseTaskQueue = require('promise-queue-task');
    let normalPromiseTaskQueue = new PromiseTaskQueue();
   
    normalPromiseTaskQueue.add((next, args) => {
    	setTimeout(() => {
        console.log("job one");
       next({
           jobNumber: 1
        	})
    	},1000);
    }).add((next, args) => {
    	console.log("job two", args.jobNumber);
    }); 
   		

   [console:]
   job one
   job two 1

2. loop promise task queue

    let PromiseTaskQueue = require('promise-queue-task');
    let looPromiseTaskQueue = new PromiseTaskQueue();
    for (let i = 0; i < 10; i++) {
    	looPromiseTaskQueue.add((next, args) => {
    		setTimeout(() => {
        		let arg = Object.assign({jobNumber: 1}, args);
        		console.log("job :" + (arg.jobNumber++));
        		if (looPromiseTaskQueue.isEmpty()) {
            		console.log('task finished')
        		} else {
            		next(arg)
        		}
    		}, 10);
    	})
    }

   [console:]
   job :1
   job :2
   job :3
   job :4
   job :5
   job :6
   job :7
   job :8
   job :9
   job :10
   task finished
