SSE (Server Sent Events)
danger
Currently not working with Deno native http
SSE is a technology for sending notifications from the server to the web browser as DOM events.
SSE in Alosaur is organized like normal Middleware.
Use context.response.setNotRespond() to interrupt the request in Middleware
important
You can read more about context.response.setNotRespond() in Middleware.
import { acceptSSE, HttpContext, PreRequestMiddleware,} from "https://deno.land/x/alosaur/mod.ts";
export class SseMiddleware implements PreRequestMiddleware { async onPreRequest(context: HttpContext) { acceptSSE(context).then(ChatHandler) // execute chat .catch(async (e) => { console.error(`failed to accept sse: ${e}`); await context.request.serverRequest.respond({ status: 400 }); });
context.response.setNotRespond(); }}
