越努力，越幸运

一、WS Koa

---

const WS = require("ws");
const Koa = require("koa");
const HTTP = require("http");

const PORT = 3000;
const app = new Koa();
const clients = new Set();
const server = HTTP.createServer(app.callback());
const wss = new WS.Server({ server });

wss.on("connection", (ws) => {
  clients.add(ws);

  ws.on("message", (message) => {
    console.log("Websocket message: ", message)
  });

  ws.on("close", () => {
    clients.delete(ws);
  });
});

server.listen(PORT, () => {
  console.log("Server listening on port " + PORT);
});

二、WS Express
