[![Build Status](https://api.travis-ci.org/inikulin/promisify-event.svg)](https://travis-ci.org/inikulin/promisify-event)

*Promisify EventEmitter's event.*

## Install

```

npm install promisify-event

```

## Usage

```js

const promisifyEvent = require('promisify-event');

// Promisify server's `listening` event:

promisifyEvent(server, `listening`).then(() => {

  // ...

});

// Promisify `error` event. `error` event always rejects the promise:

promisifyEvent(server, 'error').catch(() => {

  // ...

});

// Cancel event subscription and promise (it will be never fulfilled):

var listeningPromise = promisifyEvent(server, `listening`);

listeningPromise.cancel();

listeningPromise.then(() => {

  // Will never happen

});

```
