Socket.IO

Server

应用场景：服务器间通信。

const io = require('socket.io')().listen(6666);

io.on('connection', (socket) => {
  socket.on('client', async (data) => {
    // Codes Here
  });
});

exports.io = io;

Client

import io from 'socket.io-client';

const socket = io('ws://127.0.0.1:6666/');

// 上线汇报
socket.emit('client', () => {
  return 'Hello World';
});
socket.on('server', async (data) => {
  // 处理服务器消息
});
