# ptq

## How to use

### 1. Simple task queue

```jsx

import TaskQueue from 'ptq'

const options = {

  concurrent: 10,

  interval: 0

}

const queue = [1, 2, 3, 4, 5]

const task = (num) => {

  return new Promise((resolve) => {

    resolve(num)  

  })

}

new TaskQueue(queue, task, options).start()

```

### 2. Generate thumbnail task

```jsx

import {promisify} from 'util';

import TaskQueue from 'ptq'

import path from 'path';

import sharp from 'sharp';

import glob from 'glob';

const globPromisify = promisify(glob);

const dest = `${path.resolve(__dirname)}/160`;

globPromisify(`${path.resolve(__dirname)}/480/*`).then(files => {

  const task = file => {

    const filename = file.split('/').pop();

    return sharp(file).toFile(`${dest}/${filename}`);

  };

  new TaskQueue(files, task, {concurrent: 255}).start();

});

```
