Snippet: Discord Purge Messages from Certain Users in Multiple Channels

Discord Purge Messages from Certain Users in Multiple Channels

kangabru — kangabru

Periodically remove all messages from certain users in multiple channels. Useful to clean up messages from other bots that you don't control for example.

const lib = require('lib')({token: process.env.STDLIB_SECRET_TOKEN});

// Update to your user and channel
const minHoursAgo = 8
const user_ids = ['12345', '12345'];
const channel_ids = ['12345', '12345'];

const now = new Date()
const user_id_index = new Set(user_ids)

for (let channel_id of channel_ids) {
  
  // Get channel messages
  const messages = await lib.discord.channels['@0.2.0'].messages.list({
    channel_id,
    limit: 100,
  });

  // Filter ones from the users that aren't too new or too old
  const userMessageIds = messages
    .filter((msg) => user_id_index.has(msg.author.id))
    .filter((msg) => {
      const created = new Date(msg.timestamp)
      const hoursAgo = (now - created) / 1000 / 60 / 60
      const daysAgo = hoursAgo / 24
      const isRecent = hoursAgo < minHoursAgo // Only delete older messages
      const isTooOld = daysAgo > 14 // Can't delete messages that are too old
      return !(isRecent || isTooOld)
    })
    .map((msg) => msg.id);
    
  console.log(`Deleting ${userMessageIds.length} messages from channel ${channel_id}`);

  // Purge the messages
  if (userMessageIds.length === 1)
    await lib.discord.channels['@0.2.0'].messages.destroy({
      channel_id, message_id: userMessageIds[0],
    });
  else if (userMessageIds.length > 1)
    await lib.discord.channels['@0.2.0'].messages.bulkDelete({
      channel_id,
      messages: userMessageIds,
    });
}
