Get server information with invite link - discord.js

How can I get the server name, etc. by the invite link with discord.js?
I searched Google but there was no information about this.

You can use Client#fetchInvite that returns a Promise of an Invite like this :
const {guild} = await client.fetchInvite("The Invite");
// 'guild' is a Guild.
// If you aren't in a async function, use this :
client.fetchInvite("The Invite").then((invite) => {
// invite.guild is a Guild.
});

Getting nicknames of users of my Discord bot

I can see the names, ids and user numbers of the servers where my bot is located, but how can I get the list of users (nicknames)?
You can make use of guild.members.fetch() in order to get all members and then use the nickname property to receive their nicknames. Finally I removed all bots with a simple filter.
const members = (await message.guild.members.fetch())
.filter((m) => !m.user.bot)
.map((m) => m.displayName);
console.log(members);
Working example as a command:
client.on("message", async (message) => {
if (message.author.bot) return;
if (message.content === "!list") {
const members = (await message.guild.members.fetch())
.filter((m) => !m.user.bot)
.map((m) => m.displayName);
console.log(members);
}
});
client.login("your-token");
Thanks to #MrMythical who suggested using displayName only. That property automatically returns the normal username when no nickname has been set for a user.
Users do not have nicknames, only guild members, if you are trying to fetch a list of server member nicknames.
You can use the code snippet from below:
const map = message.guild.members.cache.filter(c=> !c.member.user.bot).map(c=>c.displayName).join('\n');
console.log(map)
The
message.guild.members.cache.filter(c=> !c.member.user.bot)
Filters bots from the list, the
.map(c=>c.displayName).join('\n');
maps the data and only the user nicknames and joins them by paragraph breaks.
If there are any issues, please comment!

How do I check what roles my bot has? [Discord.js]

I am trying to find if my bot has a specific role so it can do something else. For example:
client.user.roles.cache.find(r => r.name === 'specific role');
My error:
TypeError: Cannot read property 'cache' of undefined
Let's start of by stating that users do not have roles, therefore you have to fetch the guildMember.
Fetching the guild member is easy;
First of all, you will have to fetch the guild the user is in. For example:
var guild = client.guilds.cache.get('guild-id');
Secondly, you will have to find the user in that guild. For example:
var member = guild.members.cache.get('user-id');
Then you will be able to move forward and fetch the roles
member.roles.cache.find(r => r.name === 'role-name');
The full example:
const Discord = require('discord.js'); //Define discord.js
const client = new Discord.Client(); //Define the client
client.on('message' message => { //Event listener
//Do something here
var guild = client.guilds.cache.get(message.guild.id);
var member = guild.members.cache.get(client.user.id);
member.roles.cache.find(r => r.name === 'role-name');
});
client.login('token'); //Login
So maybe I didnt explain my problem very well but here is what I found working for me message.guild.me.roles.cache.find(r=> r.name === 'a role') thanks to everyone for helping me !!!
You need to resolve the user into a GuildMember, since users don't have roles.
To do that you need a Guild class,after that you can use the guild.member() method to convert it to a member
const guild = client.guilds.cache.get('id of the guild'),
member = guild.member(client.user.id);
member.roles.cache.find(r=> r.name === 'name')
Another issue you might run into here is, the member constant being undefined, this can be solved by using guild.members.fetch(id) or enabling the Privileged Member intent in the Discord Developer Portal

Add roles to users in specific guild through DM

When I try
message.member.roles.add('695699359634817094');
I get the following error:
TypeError: Cannot read property 'add' of undefined
Is there a specific way to add my guild ID and update their role to that specific server through DM?
My function works within the guild by calling the command, however, through DM it doesn't.
You could do this by using message.author.id to get the user's ID and then using guild.get(guild_ID).members.fetch(user_ID) to access the GuildMember of that user.
You also mentioned that you give users the ability to run that command either in DM or a text channel in your guild.
If that is the case I would suggest adding a check to see if the command is being sent to a text channel or dm channel.
if (message.channel.type === "dm") {
const member = await client.guilds.get(guild_ID).members.fetch(message.author.id);
member.roles.add(role_ID);
} else {
message.member.roles.add('695699359634817094');
}
Ignore the if statement if you intend on having the command only run from dm.
By using the info given from Syntle and tipakA this is the solution.
if (message.channel.type === "dm") {
client.guilds.get('[SeverId]').members.fetch(message.author.id).then(async () => {
await client.guilds.get('[ServerId]').members.fetch(message.author.id).then((memberid) => {
memberid.roles.add('[roleid]');
}).catch((err) => {
console.log("ERROR");
});
});
}
else
{
message.member.roles.add('[roleid]');
}

DiscordJS Backdoor Command

I have had reports off my support server of my discord js bot of my bot being abused in multiple ways.
I want to have a way upon launch of my bot to see a list of servers as well as invite links to those servers. I do not know the id of server or anything.
The most I've managed to find out how to do is this
var server = client.guilds.get("idk the id part");
console.log('I am in the following servers:');
server.createInvite().then(invite =>
console.log(server.name + "-" + invite.url)
);
});```
In your ready event (client.on('ready', () => {}), add the following lines:
client.guilds.tap(guild => {
console.log(`Name: ${guild.name} ID: ${guild.id}`);
})
This should output
Name: Test1 ID: 00000000000000
in the console for each server.
Also, considering that making a lot of invites might clog up your bot, and is generally more of a hindrance than help to server admins, you might consider making a createinvite command:
const svID = args[0];
const guild = client.guilds.find(guild => guild.id === svID);
const channel = guild.channels.find(channel => channel.position === 1);
channel.createInvite()
.then(invite => message.reply(invite.code));
You can either wait for the bot to emit it's ready event and loop through the guild collection:
client.once('ready', () => {
// client.guilds should be ready
});
or handle each guild individually:
client.on('guildCreate', (guild) => {
// The guild the bot just joined/connected to
// Should also be emitted when the bot launches
});
Either should work, but my recommendation would be the second approach, as this will also allow you to track join events whilst the bot is running.

How to know the inviter of the bot ? discord.js

I want to know who is the inviter of the bot but I don't find anything on the documentation or on forum.
If someone has an idea :/
EDIT
Recently discord added an entry in guild audit logs that log everytime someone adds a bot into the server, so you can use it to know who added the bot.
Example:
// client needs to be instance of Discord.Client
// Listen to guildCreate event
client.on("guildCreate", async guild => {
// Fetch audit logs
const logs = await guild.fetchAuditLogs()
// Find a BOT_ADD log
const log = logs.entries.find(l => l.action === "BOT_ADD" && l.target.id === client.user.id)
// If the log exits, send message to it's executor
if(log) log.executor.send("Thanks for adding the bot")
})
Old Anwser
The discord API doesn't allow this.
But, you can send a message to the Owner of the guild using the property guild.owner to get it
client.on('guildCreate', guild => {
guild.owner.send('Message here').catch(e => {
// Can't message to this user
})
})
