@chttp/ws

Minimal WebSocket router for @chttp/router, authored inside the scriptc compilable subset so the same source compiles to a native binary.

import { createRouter } from "@chttp/router";
import { WsConn, WsHandler, WsRouter } from "@chttp/ws";

class Echo extends WsHandler {
  message(c: WsConn, data: string): void {
    c.send(data);
  }
}

const app = createRouter();
app.withUpgrade(new WsRouter().ws("/echo", new Echo()).ws("/room/:name", new Echo()));
const server = app.serve({ port: 3000 });
// serve() never attaches "upgrade": wire it in your own program.
server.on("upgrade", app.upgradeHandler());

Handlers subclass WsHandler and override open, message, binary and close. WsConn exposes send, sendBinary, ping, close and param. Messages above maxPayload (1 MiB by default) close the connection with 1009. No permessage-deflate.
