[![Travis Build](http://img.shields.io/travis/maximilianschmitt/sleepqueue.svg?style=flat)](https://travis-ci.org/maximilianschmitt/sleepqueue) [![Code Coverage](https://img.shields.io/coveralls/maximilianschmitt/sleepqueue.svg)](https://coveralls.io/r/maximilianschmitt/sleepqueue) [![npm](https://img.shields.io/npm/dm/sleepqueue.svg)](https://www.npmjs.com/package/sleepqueue)

A promise-based queue that sleeps between callbacks.

## Installation

```

$ npm i sleepqueue -S

```

## Usage

### General

```js

var sleepqueue = require('sleepqueue');

// create a queue with an interval of 1 second

var queue = sleepqueue({ interval: 1000 });

// `push` pushes to the end of the queue

queue.push(print('My name is'));

queue.push(print('My name is'));

queue.push(print('My name is'));

queue.push(print('Slim Shady'));

// `unshift` pushes to the start of the queue

queue.unshift(print('Hi'));

// just a helper function

function print(what) {

  return function() {

    console.log(what);

  };

}

```

Output:

```

Hi

# (wait 1 second)

My name is

# (wait 1 second)

My name is

# (wait 1 second)

My name is

# (wait 1 second)

Slim Shady

```

### Errors

Uncaught errors and rejected promises will stop the queue and emit an error event.

```js

queue.push(print('Hello'));

queue.push(function() {

  throw 'I stopped the queue';

});

queue.push(print('Bye'));

queue.on('error', function(err) {

  console.log('Error: ' + err);

});

```

Output:

```

Hello

Error: I stopped the queue

```
