chatGPT님 가라사대 Server-Sent Events (SSE)

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...
