## Installation

```
npm install event-debug
```

## Usage

Example HTTP server where we log all event emitted by the server:

```js
var http = require('http')
var eventDebug = require('event-debug')

var server = http.createServer(function (req, res) {
  console.log('-- Received request')

  eventDebug(req) // 1st argument should behave like an EventEmitter
  eventDebug(res)

  res.end('Hello World')
})

eventDebug(server, 'MyServer') // use custom logging prefix 'MyServer'

server.listen(3000, function () {
  console.log('-- Server is running on port 3000')
})
```

When running this server and sending an HTTP request to it, the
following output will be produced (the lines written by event-debug are
all written to STDERR):
