Sending private messages to user

Solution 1:

In order for a bot to send a message, you need <client>.send() , the client is where the bot will send a message to(A channel, everywhere in the server, or a PM). Since you want the bot to PM a certain user, you can use message.author as your client. (you can replace author as mentioned user in a message or something, etc)

Hence, the answer is: message.author.send("Your message here.")

I recommend looking up the Discord.js documentation about a certain object's properties whenever you get stuck, you might find a particular function that may serve as your solution.

Solution 2:

To send a message to a user you first need to obtain a User instance.

Obtaining a User instance

• use the message.author property of a message the user sent .
• call client.users.fetch with the user's id

Once you got a user instance you can send the message with .send

Examples

client.on('message', (msg) => {
 if (!msg.author.bot) msg.author.send('ok ' + msg.author.id);
});

client.users.fetch('487904509670337509', false).then((user) => {
 user.send('hello world');
});
