Features

Support for WebTransport

The Engine.IO client can now use WebTransport as the underlying transport.

WebTransport is a web API that uses the HTTP/3 protocol as a bidirectional transport. It's intended for two-way communications between a web client and an HTTP/3 server.

References:

• https://w3c.github.io/webtransport/
• https://developer.mozilla.org/en-US/docs/Web/API/WebTransport
• https://developer.chrome.com/articles/webtransport/

For Node.js clients: until WebTransport support lands in Node.js, you can use the @fails-components/webtransport package:

import { WebTransport } from "@fails-components/webtransport";

global.WebTransport = WebTransport;

Added in 7195c0f.

Cookie management for the Node.js client

When setting the withCredentials option to true, the Node.js client will now include the cookies in the HTTP requests, making it easier to use it with cookie-based sticky sessions.

import { Socket } from "engine.io-client";

const socket = new Socket("https://example.com", {
  withCredentials: true
});

6.3.0

Bug Fixes

• properly parse relative URL with a "@" character (12b7d78)
• use explicit context for setTimeout function (#699) (047f420)

Features

• add the "addTrailingSlash" option (#694) (21a6e12)

The trailing slash which was added by default can now be disabled:

import { Socket } from "engine.io-client";

const socket = new Socket("https://example.com", {
  addTrailingSlash: false
});

In the example above, the request URL will be https://example.com/engine.io instead of https://example.com/engine.io/.

6.2.2

Bug Fixes

• simplify the check for WebSocket availability (f158c8e)

This check was added for the flashsocket transport, which has been deprecated for a while now ([1]). But it fails with latest webpack versions, as the expression "__initialize" in WebSocket gets evaluated to true.

• use named export for globalThis shim (#688) (32878ea)

Default export of globalThis seems to have a problem in the "browser" field when the library is loaded asynchronously with webpack.
