enables the client and server to negotiate a compression algorithm and its
parameters, and then selectively apply it to the data payloads of each
WebSocket message.

The extension is disabled by default on the server and enabled by default on the
client. It adds a significant overhead in terms of performance and memory
consumption so we suggest to enable it only if it is really needed.
Note that Node.js has a variety of issues with high-performance compression,
where increased concurrency, especially on Linux, can lead to
[catastrophic memory fragmentation][node-zlib-bug] and slow performance.
If you intend to use permessage-deflate in production, it is worthwhile to set
up a test representative of your workload and ensure Node.js/zlib will handle
it with acceptable performance and memory usage.

Pong messages are automatically sent in response to ping messages as required by

Just like the server example above your clients might as well lose connection
without knowing it. You might want to add a ping listener on your clients to
prevent that. A simple implementation would be:
```js
const WebSocket = require('ws');
function heartbeat() {
clearTimeout(this.pingTimeout);
// Use `WebSocket#terminate()` and not `WebSocket#close()`. Delay should be
// equal to the interval at which your server sends out pings plus a
// conservative assumption of the latency.
this.pingTimeout = setTimeout(() => {
this.terminate();
}, 30000 + 1000);
}
const client = new WebSocket('wss://echo.websocket.org/');
