Go server for announcing a stream of Server-Sent Events.
An SSE announce server creates an http.Handler that can be registered to
an existing router in your application. It takes a read-only channel of
interface objects to send to all connected clients. Once a client connects
they will begin receiving all events that occur at that point until they
disconnect. Closing the event channel will shutdown the server's background
routines.
events := make(chan interface{})
server := NewServer(events, WithBufferSize(50))
go func() {
if err := server.Start(); err != nil {
panic(err.Error())
}
}()
go func() {
defer close(events)
events <- map[string]int{"foo": 1}
events <- map[string]int{"bar": 2}
events <- map[string]int{"baz": 3}
}()
http.Handle("/events", server.ServeHTTP)
