Support subscriptions using SSE (Server-Sent Events) as alternative to websockets #476
Description
I propose that support is added for the GraphQL over Server-Sent Events Protocol, like HotChocolate has.
This simplifies authentication, since you can use the same authentication as normal HTTP requests.
I haven't looked at the GraphQL-specific parts of it, but SSE it itself technically very simple. Here is a demo:
Get(
"/sse-test",
RequestDelegate(fun (ctx: HttpContext) ->
task {
ctx.Response.Headers.Add("Content-Type", "text/event-stream")
while not ctx.RequestAborted.IsCancellationRequested do
do!
ctx.Response.WriteAsync(
$"data: {DateTime.Now}"
)
do! ctx.Response.WriteAsync("\n\n")
do! ctx.Response.Body.FlushAsync()
do! Async.Sleep(1000)
}
)
)You can test it by simply opening that endpoint in a browser (at least Edge works fine).

Good idea, why not!
