Use as `response_class=EventSourceResponse` on a *path operation* that uses `yield` to enable Server Sent Events (SSE) responses. Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible with protocols like MCP that stream SSE over `POST`. The actual encoding logic lives in the FastAPI routing layer. This class serves mainly as a marker and sets the correct `Content-Type`. ztext/event-streamN)__name__ __module__ __qualname____firstlineno____doc__ media_type__static_attributes__r\/Volumes/fast/ai/experiments/ui-tars-smoke/.venv/lib/python3.14/site-packages/fastapi/sse.pyrrs %JrrcXV^8dQhR\R,R\R\R,/#)vN field_namereturnstr)formats"r __annotate__r)$s)  #* # #* rcHVeRV9gRV9d\RV R24hV#)N  zSSE 'z' must be a single line) ValueError)r#r$s&&r _check_single_liner.$s-}$!)tqy5 ,CDEE HrcLV^8dQhR\R,R\R,/#r"r#Nr%r&)r(s"r r)r)*s"**d *sTz*rc\VR4#)r)r.r#s&r _check_event_single_liner3*s a ))rcLV^8dQhR\R,R\R,/#r0r&)r(s"r r)r).s"''sTz'cDj'rcFVeRV9d \R4h\VR4#)Nz)SSE 'id' must not contain null charactersr)r-r.r2s&r _check_id_validr7.s&}DEE a &&rcra]tRt^4toRtRtRtRtRtRt Rt ] !RR7V3RlRl4t V3Rlt RtVtR#) ServerSentEventaLRepresents a single Server-Sent Event. When `yield`ed from a *path operation function* that uses `response_class=EventSourceResponse`, each `ServerSentEvent` is encoded into the [SSE wire format](https://html.spec.whatwg.org/multipage/server-sent-events.html#parsing-an-event-stream) (`text/event-stream`). If you yield a plain object (dict, Pydantic model, etc.) instead, it is automatically JSON-encoded and sent as the `data:` field. All `data` values **including plain strings** are JSON-serialized. For example, `data="hello"` produces `data: "hello"` on the wire (with quotes).

Use this when you need to send pre-formatted text, HTML fragments, CSV lines, or any non-JSON payload. The string is placed directly into the `data:` field as-is. Mutually exclusive with `data`. r@z Optional event type name. Maps to `addEventListener(event, ...)` on the browser. When omitted, the browser dispatches on the generic `message` event. Must be a single line. rz Optional event ID. The browser sends this value back as the `Last-Event-ID` header on automatic reconnection. **Must be a single line** and must not contain null (`\0`) characters. r)gez Optional reconnection time in **milliseconds**. Tells the browser how long to wait before reconnecting after the connection is lost. Must be a non-negative integer. rz Optional comment line(s). Comment lines start with `:` in the SSE wire format and are ignored by `EventSource` clients.
