javascript - Discord.js bot responds when mentioned

Question

I'm trying to make my discord.js bot send a message when it is pinged. I was unsure how to do this so I referred to this code:

client.on('message', message => {
    if (message.content === '<@745648345216712825>') {
        message.channel.send('Message Here');
    }
});

However, this doesn't work.

Also, is it possible that my bot responds when a person mentions a specific user for example if I am mentioned by the user anywhere in a message the bot responds? If yes, can you show me how to do it?

Answer 1

Message has a property called mentions, which contains all the channels, members, roles, and users mentioned in the message. You can use the method .has(data, [options]) of MessageMentions to see if your bot was mentioned.

client.on("message", message => {
    if (message.author.bot) return false;

    if (message.content.includes("@here") || message.content.includes("@everyone")) return false;

    if (message.mentions.has(client.user.id)) {
        message.channel.send("Hello there!");
    };
});

The message event has been renamed to messageCreate in Discord.JS v13. Using message will still work, but you'll receive a deprecation warning until you switch over.
