# 서버 전송 이벤트(SSE) { #server-sent-events-sse }

브라우저 클라이언트로 데이터를 스트리밍하려면 **Server-Sent Events**(SSE)를 사용할 수 있습니다.

이는 [JSON Lines 스트리밍](stream-json-lines.md)과 비슷하지만, 브라우저가 기본적으로 [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource)를 통해 지원하는 `text/event-stream` 형식을 사용합니다.

/// info | 정보

FastAPI 0.135.0에 추가되었습니다.

            while ((line = reader.readLine()) != null) {
                // Remove comments
                final String replacedLine = line.replaceAll("#.*$", StringUtil.EMPTY).trim();

                // Skip empty lines or comment lines
                if (replacedLine.length() == 0) {
                    if (updater != null) {
                        updater.write(line);

It is just a function that can take all the same parameters that a *path operation function* can take:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8:9] *}

That's it.

**2 lines**.

And it has the same shape and structure that all your *path operation functions* have.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

  [TESTING](TESTING.asciidoc) file)
* Add integration tests, if applicable
* Make sure the code you add follows the [formatting guidelines](#java-language-formatting-guidelines)
* Lines that are not part of your change should not be edited (e.g. don't format
  unchanged lines, don't reorder existing imports)
* Add the appropriate [license headers](#license-headers) to any new files
