WebSocket

A Swarmd Worker can establish a WebSocket connection to a server with the WebSocket constructor.

Client

You can use WebSocket as client to connect to other Websocket Servers.

Server

You can also create a WebSocket server by using the Swarmd.upgradeWebSocket.

type OnRequestType = {
  req: FetchEvent;
}

async function onRequest({ req }: OnRequestType) {
  const { socket, response } = Swarmd.upgradeWebSocket(req.request);

  socket.onopen = () => {
    socket.send("Hello mom!");
  };
  socket.onclose = () => console.log("WebSocket has been closed.");
  socket.onerror = (e) => console.error("WebSocket error:", e);

  req.respondWith(response)
}

export { onRequest }
