# Server-Sent Events (SSE) { #server-sent-events-sse }

Puedes enviar datos en streaming al cliente usando **Server-Sent Events** (SSE).

Esto es similar a [Stream JSON Lines](stream-json-lines.md), pero usa el formato `text/event-stream`, que los navegadores soportan de forma nativa con la [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

It's difficult to convey emotion in text, use emojis to help. 😅

### Grammar and tone

- Use polite/formal address consistent with existing Ukrainian docs (use “ви/ваш”).
- Keep the tone concise and technical.
- Use one style of dashes. For example, if text contains "-" then use only this symbol to represent a dash.

### Headings

- Follow existing Ukrainian heading style; keep headings short and instructional.
- Do not add trailing punctuation to headings.

### Quotes

/// info | 情報

パラメータ `response_class` は、レスポンスの「メディアタイプ」を定義するためにも使用されます。

この場合、HTTPヘッダー `Content-Type` には `text/html` が設定されます。

そして、OpenAPIにもそのようにドキュメント化されます。

///

### `Response` を返す { #return-a-response }

[レスポンスを直接返す](response-directly.md)で見たように、*path operation* の中でレスポンスを直接返して上書きすることもできます。
