[![Build Status](https://travis-ci.org/StarryInternet/crony.svg?branch=master)](https://travis-ci.org/StarryInternet/crony)

Node.js library for implementing supervisord event listeners.

*Requires Node.js 6+*

### What?

[supervisord](http://supervisord.org/) implements an [event API](http://supervisord.org/events.html#event-listeners-and-event-notifications)

for listening to changes in state for the processes it manages. `crony` is an

EventEmitter that lets us do stuff with those events in JavaScript.

## Usage

```js

const crony = require('crony');

crony.on( 'event', ev => {

  // Global event handler

  // token set for the event headers

  console.log(`Headers: ${ ev.headers }`);

  // token set for the event payload

  console.log(`Payload: ${ ev.payload }`);

  // If there was an event body, we pass that along, otherwise its undefined

  console.log(`Body: ${ ev.body }`);

  // We also preserve the raw event string

  console.log(`Raw: ${ ev.raw }`);

});

// Additionally, we can also listen to specific events

crony.on( 'PROCESS_STATE_RUNNING', ev => {

  // ...

});

// Start listening for events

crony.listen();

```

## Development

```

# Install dependencies

nvm install

npm install

# Run the linter and tests

npm test

```
