Your client is using WebSockets, but Socket.IO has its own protocol (that may be transported over WebSockets, but it can also be transported over other protocols). 您的客户端正在使用WebSockets，但Socket.IO有自己的协议（可以通过WebSockets传输，但也可以通过其他协议传输）。 Change your client to use Socket.IO's own client: 将您的客户端更改为使用Socket.IO自己的客户端：

<script src="https://cdn.socket.io/socket.io-1.1.0.js"></script>

<script>

    'use strict';

    var gniazdo = io('ws://localhost:3000');

    gniazdo.on('connect', function () {

        console.log('Połączono');

        gniazdo.on('message', function (m) {
            console.log(m.data);
        });

    });

</script>
