JavaScript Discord Bot: Notify on Voice Channel Join

Other Questions Discord bot

Hey folks! I’m working on a Discord bot using JavaScript. I want it to tell me when someone hops into a voice channel. The code runs fine and shows the number of users in the console, but it’s not updating in real-time. I have to restart the bot to see changes. Any ideas on how to make it refresh the count automatically?

Here’s what I’ve got so far:

const { Client, GatewayIntentBits } = require('discord.js');
const bot = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildVoiceStates] });

bot.once('ready', () => {
    console.log(`Bot ${bot.user.tag} is online!`);
});

function checkVoiceChannel() {
    const voiceChannel = bot.channels.cache.get('VOICE_CHANNEL_ID');
    const memberCount = voiceChannel.members.size;
    console.log(`Users in channel: ${memberCount}`);
    
    if (memberCount > 0) {
        console.log('Channel is occupied');
    } else {
        console.log('Channel is empty');
    }
}

setInterval(checkVoiceChannel, 1000);

bot.login('BOT_TOKEN');

I’ve tried clearing the cache and resetting the member count, but no luck. How can I get the latest member count each time? Thanks for any help!

I’ve dealt with this exact problem before, and I can tell you that relying on setInterval for real-time updates isn’t the best approach. The Discord.js library actually provides a much more efficient way to handle this using event listeners.

In my experience, the ‘voiceStateUpdate’ event is your best bet here. It fires whenever there’s any change in a user’s voice state, including joining or leaving a voice channel. Here’s a snippet that should do the trick:

bot.on(‘voiceStateUpdate’, (oldState, newState) => {
const targetChannel = bot.channels.cache.get(‘VOICE_CHANNEL_ID’);
if (newState.channel === targetChannel || oldState.channel === targetChannel) {
console.log(Users in channel: ${targetChannel.members.size});
console.log(targetChannel.members.size > 0 ? ‘Channel is occupied’ : ‘Channel is empty’);
}
});

This way, you’ll get instant updates without any polling or manual cache clearing. Just make sure to replace ‘VOICE_CHANNEL_ID’ with your actual channel ID. Hope this helps solve your issue!

hey, i had a similar issue. try using the ‘voiceStateUpdate’ event instead of setInterval. it triggers when someone joins/leaves voice channels. something like:

bot.on(‘voiceStateUpdate’, (oldState, newState) => {
// check if the channel changed
if (newState.channelId !== oldState.channelId) {
// do your stuff here
}
});

this should give u real-time updates without restarts. hope it helps!

The issue you’re facing is likely due to caching. Discord.js caches data to improve performance, but this can lead to outdated information.

Instead of using setInterval, I’d recommend utilizing Discord.js events. Specifically, the ‘voiceStateUpdate’ event will trigger whenever someone joins, leaves, or moves between voice channels.

Here’s a modified version of your code that should work:

bot.on('voiceStateUpdate', (oldState, newState) => {
  const channel = bot.channels.cache.get('VOICE_CHANNEL_ID');
  if (newState.channel === channel || oldState.channel === channel) {
    const memberCount = channel.members.size;
    console.log(`Users in channel: ${memberCount}`);
    console.log(memberCount > 0 ? 'Channel is occupied' : 'Channel is empty');
  }
});

This approach will update in real-time without needing to restart the bot or use intervals.
