Node.js 将redis订阅消息中继到websocket

使用每分钟接收数据的模式

（*：*：*）

订阅redis；还作为websocket服务器运行，检查特定订阅消息，如果特定订阅消息的数据由redis返回，则直接将从redis返回的数据推送到该WS通道

例如：如果WS-client想要订阅一个名为Binance:BTC-USDT:1m的频道，并且该数据每分钟都来自redis，那么我如何在从redis获得新数据后立即将其发送到WS-client

实现这一点最有效的方法是什么

export {};
const redis = require("redis");
const WebSocket = require("ws");

const subscriber = redis.createClient();
subscriber.psubscribe("*:*:*");
const wss = new WebSocket.Server({ port: 8080 });

subscriber.on("pmessage", function (pattern, channel, message) {
  console.log(message);
});

wss.on("connection", function connection(ws) {
  ws.on("message", function incoming(message) {
    console.log("Server Received: %s", message);
  });

  ws.send("something from server");
});
