Change user nickname with discord.js

Question

I wonder if you can help (I search it and nothing...) I am learning how to work with discord.js node and I want to change my user nickname (not the username itself)

Answer 1

To do this, we need to get the first mentioned user. Doing that would be:

let nickedUser = message.mentions.users.first();

After we do that, we need to then get what we want to call the user. I just use nickReason, you can do whatever you want to do.

let nickReason = args.join(" ").slice(22);

Alright, after that we need to check if there was no mentioned user. This is easy:

if(!nickedUser) return message.channel.send("No mentioned user.");

Once after adding that, we need to check if there is a valid name, this is easy as well:

if(!nickReason) return message.channel.send("Not having a name is not a good nickname.");

Now we check if they have the MANAGE_NICKNAMES permissions, which is also easy. We will also check if the mentioned user has MANAGE_NICKNAMES permission:

if(!message.member.hasPermission("MANAGE_NICKNAMES")) return message.channel.send("No permissions!");

if(nick.hasPermission("MANAGE_NICKNAMES")) return message.channel.send("No need to change the nickname of someone that can change nicknames as well.");

Alright, now that we have this, we change their nickname!

nickedUser.setNickname(nickReason);

message.channel.send("Changed " + nickedUser + "'s nickname!");
