我觉得在connect时加上容错判断会好点

Thank you for your feedback! You're absolutely right that adding better error handling during connection would improve the code. And the article already includes error handling mechanisms where you can implement any fault tolerance logic:

client.on('error', (error) => {
  console.error('connection failed', error)
})

The best practices are already covered: configuring the reconnection period, logging errors, and using end(true) for forced disconnection when needed.

Could you clarify what specific connection scenarios you'd like to see improved? That would help me provide more targeted suggestions for the article.
