javascript - Finding who deleted the message - Stack Overflow

My discord.js bot is programmed to log deleted messages. I have the code setup, but I was wondering if there was a way to see who deleted it? Thanks.

Heres the code:

bot.on("messageDelete", (messageDelete) => {

  let DeleteEmbed = new Discord.RichEmbed()
  .setTitle("**DELETED MESSAGE**")
  .setColor("#fc3c3c")
  .addField("Author", messageDelete.author.tag, true)
  .addField("Channel", messageDelete.channel, true)
  .addField("Message", messageDelete.content)
  .setFooter(`Message ID: ${messageDelete.id} | Author ID: ${messageDelete.author.id}`);

  let DeleteChannel = messageDelete.guild.channels.find(x => x.name === "delete-log");
  DeleteChannel.send(DeleteEmbed);
});

Thanks!

There is no smooth and accurate way to do this as @NintendoZaedus correctly pointed out. However I made a way to somewhat do this with minimal possible mistakes made.

Do note these are impossible at the time of writing this and will return 'Unknown':

• See which bot deleted a message as Discord does not log message deletions for bots
• See if the author deleted their own message (Discord does not log this either)
• 100% determine if the message deleted matches the fetched audit log due to Discord not including the message ID in audit logs

// If discord.js isn't defined, add this, if it is, don't.
const Discord = require("discord.js");

bot.on("messageDelete", async (messageDelete) => {
  // Add latency as audit logs aren't instantly updated, adding a higher latency will result in slower logs, but higher accuracy.
  await Discord.Util.delayFor(900);

  // Fetch a couple audit logs than just one as new entries could've been added right after this event was emitted.
  const fetchedLogs = await messageDelete.guild.fetchAuditLogs({
    limit: 6,
    type: 'MESSAGE_DELETE'
  }).catch(console.error);

  const auditEntry = fetchedLogs.entries.find(a =>
    // Small filter function to make use of the little discord provides to narrow down the correct audit entry.
    a.target.id === messageDelete.author.id &&
    a.extra.channel.id === messageDelete.channel.id &&
    // Ignore entries that are older than 20 seconds to reduce false positives.
    Date.now() - a.createdTimestamp < 20000
  );

  // If entry exists, grab the user that deleted the message and display username + tag, if none, display 'Unknown'. 
  const executor = auditEntry.executor ? auditEntry.executor.tag : 'Unknown';

  // Finally, prepare the embed and send the log. (using similar code posted by thread author but improved)

  // <Discord>.MessageEmbed for v12, <Discord>.RichEmbed for older.
  const DeleteEmbed = new Discord.MessageEmbed()
    .setTitle("DELETED MESSAGE")
    .setColor("#fc3c3c")
    .addField("Author", messageDelete.author.tag, true)
    // New field for user which deleted the message.
    .addField("Deleted By", executor, true)
    .addField("Channel", messageDelete.channel, true)
    // Messages can be empty too, but I won't be going over how to include embeds/attachments, just displaying 'None' instead to avoid undefined/null.
    .addField("Message", messageDelete.content || "None")
    .setFooter(`Message ID: ${messageDelete.id} | Author ID: ${messageDelete.author.id}`);

  const DeleteChannel = messageDelete.guild.channels.find(x => x.name === "delete-log");
  DeleteChannel.send(DeleteEmbed);
});

There is no way of doing it except through the audit logs which might be very buggy and hard to work with. I hope this is a little help to you.

The bot tries to trace who deleted the message. If we can find the audit log that contains the correct information, we will write the user in question in a embed field, otherwise we will write that it was not possible to trace this user. I've tried the code multiple times and it works in both cases. unfortunately it is not known whether or not the API will return the user who deleted the message, this is caused by a lack in the API

/**
 * Emitted whenever a message is deleted.
 * @param {Message} message
 * Not always is possible to retrieve who deleted the message, this is caused by Discord API lack.
 */
client.on(Events.MessageDelete, async (message) => {
    const mes = message.content;

    if (!mes) return;

    let attachments = await message.attachments.map(attachment => attachment.url);

    const embed = new EmbedBuilder()
        .setColor("Yellow")
        .setTitle(`\`
