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

You can stream data to the client using **Server-Sent Events** (SSE).

This is similar to [Stream JSON Lines](stream-json-lines.md), but uses the `text/event-stream` format, which is supported natively by browsers with the [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

/// info

Added in FastAPI 0.135.0.

## Stream JSON Lines with FastAPI { #stream-json-lines-with-fastapi }

To stream JSON Lines with FastAPI you can, instead of using `return` in your *path operation function*, use `yield` to produce each item in turn.

You can send (and receive) many messages:

And all of them will use the same WebSocket connection.

## Using `Depends` and others { #using-depends-and-others }

In WebSocket endpoints you can import from `fastapi` and use:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`
