Sockette是一个很小的（348字节）包装器WebSocket，如果连接丢失，它将自动重新连接！

Sockette还允许您重用实例，从而无需重新声明所有事件侦听器。 您可以直接访问WebSocket每个EventListener回调（via event.target）中的（当前）底层。

sockette安装

npm install --save sockette

sockette使用 

const Sockette = require('sockette');

const ws = new Sockette('ws://localhost:3000', {
  timeout: 5e3,
  maxAttempts: 10,
  onopen: e => console.log('Connected!', e),
  onmessage: e => console.log('Received:', e),
  onreconnect: e => console.log('Reconnecting...', e),
  onmaximum: e => console.log('Stop Attempting!', e),
  onclose: e => console.log('Closed!', e),
  onerror: e => console.log('Error:', e)
});

ws.send('Hello, world!');
ws.json({type: 'ping'});
ws.close(); // graceful shutdown

// Reconnect 10s later
setTimeout(ws.reconnect, 10e3);
