# Async Task Manager

> A JavaScript library for controlling asynchronous parallelism.

*其他语言版本： [简体中文](README.zh.md)*

## Background

`x-atm` is designed to help you control asynchronous tasks.

For example, in parallel file uploading, most browsers only support 6 paralle http requests. If you don't control async tasks(http request), it will block the request stack, and cause performance problem. But with `x-atm`, we can control the number of asynchronous requests to improve the upload efficiency.

## Installation

```

yarn add x-atm

```

## Basic usage

```javascript

const ATM = require('x-atm');

function handleAll() {

  console.log("all task resolved");

}

let task = new ATM({maxParallel: 4,resolve: handleAll, strict: true});

const asyncTask = (index) => {

  return new Promise((resolve, reject) => {

    let random = parseInt(Math.random() * 10000);

    setTimeout(() => {

      if (random > 5000) {

        resolve('value is ' + random + ' current task ' + index);

      } else {

        reject('reason is ' + random + ' current task ' + index);

      }

    }, random);

  });

}

asyncTask.resolve = console.log

asyncTask.reject = console.log

for(let i = 0; i < 10; i++) {

  task.push(asyncTask);

}

task.start();

```
