Handling Discord.js Events

Handling Discord.js Events

DisTube provides utilities to help you handle Discord.js events for better user experience.

Leave the voice channel if there is no user in it

import { isVoiceChannelEmpty } from "distube";

client.on("voiceStateUpdate", oldState => {
  if (!oldState?.channel) return;
  const voice = distube.voices.get(oldState);
  if (voice && isVoiceChannelEmpty(oldState)) {
    voice.leave();
  }
});

Pause the queue if there is no user in the voice channel and resume it if there is

import { isVoiceChannelEmpty } from "distube";

client.on("voiceStateUpdate", oldState => {
  if (!oldState?.channel) return;
  const queue = distube.getQueue(oldState);
  if (!queue) return;
  if (isVoiceChannelEmpty(oldState)) {
    queue.pause();
  } else if (queue.paused) {
    queue.resume();
  }
});

Leave voice channel after a period of inactivity

import { Events } from "distube";

const inactivityTimers = new Map();

// Start timer when queue finishes
distube.on(Events.FINISH, queue => {
  const timer = setTimeout(() => {
    queue.voice.leave();
    inactivityTimers.delete(queue.id);
  }, 5 * 60 * 1000); // 5 minutes

  inactivityTimers.set(queue.id, timer);
});

// Clear timer when new song plays
distube.on(Events.PLAY_SONG, queue => {
  const timer = inactivityTimers.get(queue.id);
  if (timer) {
    clearTimeout(timer);
    inactivityTimers.delete(queue.id);
  }
});

// Clear timer when queue is deleted
distube.on(Events.DELETE_QUEUE, queue => {
  const timer = inactivityTimers.get(queue.id);
  if (timer) {
    clearTimeout(timer);
    inactivityTimers.delete(queue.id);
  }
});

Handle bot being moved to another channel

client.on("voiceStateUpdate", (oldState, newState) => {
  // Check if it's the bot
  if (oldState.member?.id !== client.user?.id) return;

  // Bot was moved to a different channel
  if (oldState.channelId && newState.channelId && oldState.channelId !== newState.channelId) {
    const queue = distube.getQueue(oldState.guild.id);
    if (queue) {
      queue.textChannel?.send(`Moved to <#${newState.channelId}>`);
    }
  }
});
