Hello, I am very glad to see the Java version of the server, may I ask what version of Socket.IO corresponds to 4.0.1 version, and what version should I use Socket. io-client? Thank you

Hi,
Major versions of this library is compatible with major versions of the nodejs library. So, for client v4.x, you can use any server version 4.x.
