auto-sleep for afk

[VuHoangQuan2008]

I made a bot that can sleep when you type "sleep" in the chat but I had a auto-crop farm so I need the bot always sleep when it is night time. Someone please help me, I can't figure this out. Or any solution that the autofarms always work in daytime?


Code:
const mineflayer = require('mineflayer')

const bot = mineflayer.createBot({
host: '192.168.1.xxx',
username: 'YoBot',
auth: 'offline'
})

function createBot () {
bot.once('spawn', () => {
bot.chat("/gamemode creative")
})
bot.on('chat', (username, message) => {
if (username === bot.username) return
switch (message) {
case 'sleep':
goToSleep()
break
case 'wakeup':
wakeUp()
break
}
})

  bot.on('sleep', () => {
    bot.chat('Good night!')
  })
  bot.on('wake', () => {
    bot.chat('Good morning!')
  })
  
  async function goToSleep () {
    const bed = bot.findBlock({
      matching: block => bot.isABed(block)
    })
    if (bed) {
      try {
        await bot.sleep(bed)
        bot.chat("I'm sleeping")
      } catch (err) {
        bot.chat(`I can't sleep: ${err.message}`)
      }
    } else {
      bot.chat('No nearby bed')
    }
  }
  
  async function wakeUp () {
    try {
      await bot.wake()
    } catch (err) {
      bot.chat(`I can't wake up: ${err.message}`)
    }
  }
bot.on('error', (err) => console.log(err))
// Log errors and kick reasons:
bot.on('kicked', console.log)
bot.on('error', console.log)
bot.on('end', createBot)

}

createBot()

You can use the time event (https://github.com/PrismarineJS/mineflayer/blob/master/docs/api.md#time) and then use bot.time to figure out if it's night and sleep
