Socket.IO Fiddle

$ npm install           # install the dependencies
$ npm start             # run the server
$ npm run client        # run the nodejs client

And point your browser to http://localhost:3000. Optionally, specify a port by supplying the PORT env variable.

Other branches:

• TypeScript
• Multiple servers (with Redis adapter/emitter)
• Example with CORS
• Example with self-signed certificate
• With Vite
• With µWebSockets.js

socket.io-redis & @socket.io/admin-ui

Only when socket.io-redis & @socket.io/admin-ui works together and socket.emit('xxx', cb) the sever will crash

  // with callback it will crush server
  socket.emit('login', {user:"10001",token:"fake"},reply => {})
  // no callback it is fine
  // socket.emit('login', {user:"10001",token:"fake"})

Both socket.io-redis 6&7 have this problem.
