discord.js rateLimitPerUser 不是 function

Question

I'm making a normal discord bot and I wanna set the slowmode here's my full code:

bot.on("message", message => {

if(message.content.toLowerCase().startsWith(prefix+"slowmode")) {
  var str = message.content.split(prefix+"slowmode ");
  var num = parseInt(str[1],10);
  message.channel.rateLimitPerUser == rts;
  message.channel.send("Slowmode Setted");
}

});

but I get a error:

TypeError: message.channel.rateLimitPerUser is not a function

I also tried other ways like:

message.channel.rateLimitPerUser = num;

but they didn't work too. I searched the documentary and internet to set the slowmode but they didn't work too. [ sorry form my bad english:( ]

Answer 1

You need use .setRateLimitPerUser

if (message.content.toLowerCase().startsWith(prefix + 'slowmode')) {
    var str = message.content.split(prefix + 'slowmode ');
    var num = parseInt(str[1], 10);
    message.channel.setRateLimitPerUser(num).then(() => {
        message.channel.send(`Slowmode Setted to ${num}s. :thumbsup:`);
    });
}

Answer 2

client.on("message", (message) => {
        let modchannel = db.fetch(`verify_${message.guild.id}`);
                var sChannel = message.guild.channels.cache.get(modchannel)
            if (!sChannel) return
    message.sChannel.setRateLimitPerUser(5);
});
