chatGPT 님에게 server push 예제를 알려줘라고 했더니 아래와 같이 알려주신다.
| Server push is a technique that allows a server to push data to a client without the client first making a request for the data. In JavaScript, this can be achieved using the Server-Sent Events (SSE) API. Here's an example of how you can use SSE to implement server push in JavaScript:
 On the server side, you need to create an endpoint that will send the SSE messages. In this example, we'll create a simple Node.js server:

| const http = require('http'); 
 const server = http.createServer((req, res) => {
 if (req.url === '/sse') {
 res.writeHead(200, {
 'Content-Type': 'text/event-stream',
 'Cache-Control': 'no-cache',
 'Connection': 'keep-alive'
 });
 
 setInterval(() => {
 res.write(`data: ${new Date().toISOString()}\n\n`);
 }, 1000);
 } else {
 res.writeHead(404);
 res.end();
 }
 });
 
 server.listen(3000);
 | const source = new EventSource('/sse'); 
 source.onmessage = (event) => {
 console.log(event.data);
 };
 | 
 
아무튼 SSE를 검색해보는데.. jquery 연관은 잘 안보이고
EventSource.onmessage() 로 처리 가능만 하다면야 머...
