# Introduction

This module provides a streaming interface to [Prosodys internal statistics][doc:statistics] via

[Server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events).

## Example

```js

var evtSource = new EventSource("/stats_stream");

/*

 * An event with all current statistics in the form of a JSON object.

 * Normally sent only once, when first connected to the stream.

 */

evtSource.addEventListener("stats-full", function(e) {

	var initial_stats = JSON.parse(e.data);

	console.log(initial_stats);

}, false);

/*

 * An event containing only statistics that have changed since the last

 * 'stats-full' or 'stats-updated' event.

 */

evtSource.addEventListener("stats-updated", function(e) {

	var updated_stats = JSON.parse(e.data);

	console.log(updated_stats);

}, false);

```
