websock-lowfat-promise is a zero-dependencies low-fat-promisified ws-websocket library.

Requirements

It runs inside any webbrowser or node environment that supports promises.

It can be used with most existing websocket libraries.

Basic usage

The following sample code should speak for itself:

const WebSocket = require("ws");
const wspromise = require("websocket-lowfat-promise");

async function runme() {
  const wsp = new wsppromise(new WebSocket("wsp://foo.com/bar"));
  await wsp.open();
  await wsp.send("Hello world!  Send me a response please.");
  var response = await wsp.recv();
  console.log(response);
  await wsp.close();
  console.log("Socket has been closed");
}

runme();
