```
Note that under certain circumstances (notably a draft-76 client connecting
through an HTTP proxy), the WebSocket handshake will not be complete after you
call `new WebSocket()` because the server will not have received the entire
handshake from the client yet. In this case, calls to `ws.send()` will buffer
the message in memory until the handshake is complete, at which point any
buffered messages will be sent to the client.
If you need to detect when the WebSocket handshake is complete, you can use the
`onopen` event.
If the connection's protocol version supports it, you can call `ws.ping()` to
send a ping message and wait for the client's response. This method takes a
message string, and an optional callback that fires when a matching pong message
is received. It returns `true` iff a ping message was sent. If the client does
not support ping/pong, this method sends no data and returns `false`.
```js
ws.ping('Mic check, one, two', function() {
// fires when pong is received
});
```
## Using the WebSocket client
The client supports both the plain-text `ws` protocol and the encrypted `wss`
protocol, and has exactly the same interface as a socket you would use in a web
browser. On the wire it identifies itself as hybi-13, though it's compatible
with servers speaking later versions of the protocol.

## Handling EventSource connections in Node
EventSource connections provide a very similar interface, although because they
only allow the server to send data to the client, there is no `onmessage` API.
EventSource allows the server to push text messages to the client, where each
message has an optional event-type and ID.
```js
var WebSocket = require('faye-websocket'),
EventSource = WebSocket.EventSource,
http = require('http');
var server = http.createServer();
server.addListener('request', function(request, response) {
if (EventSource.isEventSource(request)) {
var es = new EventSource(request, response);
console.log('open', es.url, es.lastEventId);
// Periodically send messages
var loop = setInterval(function() { es.send('Hello') }, 1000);
es.onclose = function() {
clearInterval(loop);
es = null;
};
} else {
// Normal HTTP request
response.writeHead(200, {'Content-Type': 'text/plain'});
response.write('Hello');
response.end();
}
});
server.listen(8000);
```
The `send` method takes two optional parameters, `event` and `id`. The default
event-type is `'message'` with no ID. For example, to send a `notification`
event with ID `99`:
```js
es.send('Breaking News!', {event: 'notification', id: '99'});
```
The `EventSource` object exposes the following properties:
* <b><tt>url</tt></b> is a string containing the URL the client used to create
the EventSource.
* <b><tt>lastEventId</tt></b> is a string containing the last event ID
received by the client. You can use this when the client reconnects after a
dropped connection to determine which messages need resending.
When you initialize an EventSource with ` new EventSource()`, you can pass
configuration options after the `response` parameter. Available options are:
* <b><tt>retry</tt></b> is a number that tells the client how long (in seconds)
it should wait after a dropped connection before attempting to reconnect.
* <b><tt>ping</tt></b> is a number that tells the server how often (in seconds)
to send 'ping' packets to the client to keep the connection open, to defeat
timeouts set by proxies. The client will ignore these messages.
For example, this creates a connection that pings every 15 seconds and is
retryable every 10 seconds if the connection is broken:
```js
var es = new EventSource(request, response, {ping: 15, retry: 10});
```
You can send a ping message at any time by calling `es.ping()`. Unlike WebSocket,
the client does not send a response to this; it is merely to send some data over
the wire to keep the connection alive.
