Bumps ws to 8.18.3 and updates ancestor dependency socket.io-client. These dependencies need to be updated together.

Updates ws from 7.4.6 to 8.18.3

Release notes

Sourced from ws's releases.

8.18.3

Bug fixes

  • Fixed a spec violation where the Sec-WebSocket-Version header was not added to the HTTP response if the client requested version was either invalid or unacceptable (#2291).

8.18.2

Bug fixes

  • Fixed an issue that, during message decompression when the maximum size was exceeded, led to the emission of an inaccurate error and closure of the connection with an improper close code (#2285).

8.18.1

Bug fixes

  • The length of the UNIX domain socket paths in the tests has been shortened to make them work when run via CITGM (021f7b8b).

8.18.0

Features

  • Added support for Blob (#2229).

8.17.1

Bug fixes

  • Fixed a DoS vulnerability (#2231).

A request with a number of headers exceeding the[server.maxHeadersCount][] threshold could be used to crash a ws server.

const http = require('http');
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 0 }, function () {
const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
const headers = {};
let count = 0;
for (let i = 0; i < chars.length; i++) {
if (count === 2000) break;
for (let j = 0; j &lt; chars.length; j++) {
  const key = chars[i] + chars[j];
  headers[key] = 'x';

Custom transport implementations

The transports option now accepts an array of transport implementations:

import { io } from "socket.io-client";
import { XHR, WebSocket } from "engine.io-client";
const socket = io({
transports: [XHR, WebSocket]
});

Here is the list of provided implementations:
