Documentation

_encode(data: any[] | any except function) -> Uint8Array

Synchronously packs data with msgpack format (not recommended)

const packet = msgpack._encode({
  thing: 5.88283882919
});
socket.send(packet);

_decode(data: any[] | ArrayBuffer) -> any

Synchronously unpacks data with msgpack format (not recommended)

socket.on("message", ({ data }) => {
  console.log(msgpack._decode(data));
});

async pack(data: any[] | any except function) -> Uint8Array

Packs the data with msgpack format. Recommended for most of cases, since it's easier to control exceptions that happen while packing data.

const socket = new WebSocketStream("wss://127.0.0.1");
const { readable, writable, extensions, protocol } = await wss.opened;

const writer = writable.getWriter();

msgpack.pack("hello").then(raw =>
  writer.write(raw)).catch(console.log);

async unpack(data: any[] | ArrayBuffer) -> any

Unpacks the data with msgpack format. Recommended for most of cases, since it's easier to control exceptions that happen while packing data.

const socketWorker = new Worker("ws.js");

socketWorker.onmessage = async ({ data }) => {
  const [ packetSid, packetData ] = await msgpack.unpack(data);

  console.log(packetSid, packetData);
}

socketWorker.postMessage("ready");
