Server-Sent Events
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.
Sample code
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!",
},
})
}
event: message
data: some data\\nmore data
id: 124
event: message
data: {"content":"hi!","date":1431540810,"user":"manu"}
Content-Type
fmt.Println(sse.ContentType)
text/event-stream
Decoding support
There is a client-side implementation of SSE coming soon.
