Bump engine.io and karma in /demo

[dependabot]

Bumps engine.io to 6.4.1 and updates ancestor dependency karma. These dependencies need to be updated together.

Updates engine.io from 3.2.1 to 6.4.1

Release notes

Sourced from engine.io's releases.

6.4.1

This release contains 6e78489, which exports the BaseServer class in order to restore the compatibility with the nodenext module resolution strategy of TypeScript.

Reference: https://www.typescriptlang.org/tsconfig/#moduleResolution

Related: socketio/socket.io#4621

Links

• Diff: socketio/engine.io@6.4.0...6.4.1
• Client release: -
• ws version: ~8.11.0 (no change)

6.4.0

Features

• add support for Express middlewares (24786e7)

This commit implements middlewares at the Engine.IO level, because Socket.IO middlewares are meant for namespace authorization and are not executed during a classic HTTP request/response cycle.

A workaround was possible by using the allowRequest option and the "headers" event, but this feels way cleaner and works with upgrade requests too.

Syntax:

engine.use((req, res, next) => {
  // do something
next();
});
// with express-session
import session from "express-session";
engine.use(session({
secret: "keyboard cat",
resave: false,
saveUninitialized: true,
cookie: { secure: true }
}));
// with helmet
import helmet from "helmet";
engine.use(helmet());
