1、H5 演示地址：

/demo/demo01-js-ws/

前端源码可以直接看网页源码（不太好看啊）。

2、配套服务端代码 - node.js：

包配置里添加依赖（package.json）

{
  "name": "demo",
  "description": "socket.d for node.js demo",
  "author": "noear",
  "dependencies": {
    "@noear/socket.d": "2.5.11"
  }
}

代码（server.js）

const {SocketD}  = require('@noear/socket.d');

function main(){
   let server = SocketD.createServer("sd:ws")
       .config(c=>c.port(8602).fragmentSize(1024 * 1024))
       .listen(buildListener())
       .start();
}

function buildListener() {
    return SocketD.newEventListener()
        .doOnOpen(s => {
            console.info("onOpen: " + s.sessionId());
        }).doOnMessage((s, m) => {
            console.info("onMessage: " + m);
        }).doOn("/demo", (s, m) => {

                }
                s.replyEnd(m, SocketD.newEntity("welcome to my home!"));

                return;
            }

        })
