+#Server-Sent Events [![GoDoc](https://godoc.org/github.com/manucorporat/sse?status.svg)](https://godoc.org/github.com/manucorporat/sse) [![Build Status](https://travis-ci.org/manucorporat/sse.svg)](https://travis-ci.org/manucorporat/sse)
+
+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/).
+
+- [Real world demostration using Gin](http://sse.getgin.io/)
+- [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/manucorporat/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!",
+		},
+	})
+}
+```
+```
+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)
+```
+```
+text/event-stream
+```
+
+##Decoding support
+
+There is a client-side implementation of SSE coming soon.
