I want my discord bot to send a random message to a text room given by user [by channel id or channel name]

Question

so what I am trying to do is when a user write a command such as

!setchannel #test or !setchannel 86xxxxxxxxxxxxxxx

then the bot will send the random messages to that channel every certain time.

Note that I did the random messages code but I still stuck on creating the !setchannel command.

I am using discord.js v12.5.3

You'll have to use a database to achieve what you're trying to do

An example using quick.db

const db = require(`quick.db`)
const prefix = "!"
client.on("message", async message => {
    if (!message.content.startsWith(prefix)) return;
    const args = message.content.slice(prefix.length).trim().split(/ +/g)
    const cmd = args[0]
    if (cmd === "setchannel") {
        let c_id = args[1]
        if (!c_id) return message.reply("You need to mention a channel/provide id")
        c_id = c_id.replace(/[<#>]/g, '')
        if (client.channels.cache.get(c_id)) {
            await db.set(`_channel_`, c_id) //Set in the database
        } else {
            return message.reply("Not a valid channel")
        }


    }
})

Changes to make in your code

client.on('ready', async () => {
       let c_id = await db.get(`_channel_`)
        
        cron.schedule('*/10 * * * * *', () => {
        const zkrRandom = zkrList[Math.floor(Math.random() * zkrList.length)]
        const zkrEmbed = new Discord.MessageEmbed()
        
              .setTitle('xx')
              .setDescription(zkrRandom)
              .setFooter("xx")
              .setColor('#447a88')
              .setAuthor('xx#8752')
        
        
            
            client.channels.cache.get(c_id).send(zkrEmbed)
          })
        })

The above sample of quick.db is just an example

If you're using repl.it, I recommend you to use quickreplit
