How to detect if the author of a message was a Discord bot?

Question

The title explains my question. This question might sound stupid, but how do I detect if the author of a message was a Discord bot?

Thanks.

Answer 1

If you want to check if a message author is a bot account you can easily do:

if(message.author.bot) return;

This will return if a user is a bot. If it isn't will keep going.
If you want to check if the message author is the logged in bot you can do:

if(message.author.id === client.user.id) return;

This is gonna return if the message author is the bot, it will keep going if its another bot.

Answer 2

for those looking for an answer on how to check if it was your bot who added a reaction. In that case you can check like it like:

client.on('messageReactionAdd', (messageReaction, user) => {
  if (messageReaction.me === false) {
    // This reaction was not added by the bot
  }
});
