Server-sent events (SSE) is a technology where a browser receives automatic updates from a server via HTTP connection. The Server-Sent Events EventSource API is [standardized as part of HTML5[1] by the W3C](http://www.w3.org/TR/2009/WD-eventsource-20091029/).

- [Read this great SSE introduction by the HTML5Rocks guys](http://www.html5rocks.com/en/tutorials/eventsource/basics/)
- [Browser support](http://caniuse.com/#feat=eventsource)

## Sample code

```go
import "github.com/gin-contrib/sse"

func httpHandler(w http.ResponseWriter, req *http.Request) {
  // data can be a primitive like a string, an integer or a float
  sse.Encode(w, sse.Event{
    Event: "message",
    Data:  "some data\nmore data",
  })

// also a complex type, like a map, a struct or a slice
  sse.Encode(w, sse.Event{
    Id:    "124",
    Event: "message",
    Data: map[string]interface{}{
      "user":    "manu",
      "date":    time.Now().Unix(),
      "content": "hi!",
    },
  })
}
```

```sh
event: message
data: some data\\nmore data

id: 124
event: message
data: {"content":"hi!","date":1431540810,"user":"manu"}

```

## Content-Type

```go
fmt.Println(sse.ContentType)
```

```sh
text/event-stream
```

## Decoding support

There is a client-side implementation of SSE coming soon.
