How to get bot to reply to user with a (#)ping - discord.js

I am trying to get a bot to respond to people with a ping in the message, for example: "#user", but everything I've tried have given me not a function error or undefined error. All the stuff I can find about it is either outdated for discord.js v14 or it is for discord.py
Here is my code:
client.on("messageCreate", (message) => {
if (message.content.startsWith("test")) {
const user = message.author.userId();
message.channel.reply(`Hello <#${user}>`)
}
});
I've also attempted variations of the .userId() part - such as .tag, .user.id, and .username but all of them have come back with some sort of undefined error. I know it says userId is a snowflake on discord.js but I am unsure on how to use that for I am fairly new to javascript and discord.js. Also, please know that I am using Replit to host the bot and have discord.js#14.5.0 installed.

So, there are a couple issues here.
Issue 1
message.author.userId() is not a function. When trying to get a user's ID, you want to know what each property is returning.
message -> returns the Message object, which contains the data for the message.
message.author -> returns the User object, which contains the data for the user profile.
message.member -> returns the Member object, which contains the data for the guild member profile.
And so on.
In this case, you're going to want to get the User object: being message.author. You've already figured this out.
Now, the User Object has it's own set of properties (which you can find in the documentation at https://discord.js.org/).
The property that you are looking for is: .id, or in your use-case, message.author.id.
Your other attempts, message.author.tag returns the tag, message.author.user.id will throw an error, and message.author.username returns the user's username.
Issue 2
Your second issue is the .reply() method that you're using. The Channel Object doesn't have a .reply() method, but the message does.
So, how you would write this code:
client.on("messageCreate", async(message) => {
if(message.content.toLowerCase().startsWith("test")) {
// Note that I added the .toLowerCase() method to ensure you can do tEST and it still works!
message.reply({ content: `Hello, ${message.author}!` });
}
});
Also, a cool feature that discord.js has is that you can supply the User or Member Object to the content of a message, and it will automatically mention the desired person.
Hope this helps!

How to not send bots message edit discord.js

I have a message edit log but I want to stop sending the log if a mobs message was updated, I tried a few codes like
if(bot.oldMessage.content.edit()){
return;
}
It showed and error
cannot read property 'edit' of undefined
I then removed edit then content was undefined. The code for the message update is below.
The Code
module.exports = async (bot, oldMessage, newMessage) => {
let channels = JSON.parse(
fs.readFileSync('././database/messageChannel.json', 'utf8')
);
let channelId = channels[oldMessage.guild.id].channel;
let msgChannel = bot.channels.cache.get(channelId);
if (!msgChannel) {
return console.log(`No message channel found with ID ${channelId}`);
}
if (oldMessage.content === newMessage.content){
return;
}
let mEmbed = new MessageEmbed()
.setAuthor(oldMessage.author.tag, oldMessage.author.displayAvatarURL({dynamic: true}))
.setColor(cyan)
.setDescription(`**Message Editied in <#${oldMessage.channel.id}>**`)
.addField(`Before`, `${oldMessage.content}`)
.addField(`After`, `${newMessage.content}`)
.setFooter(`UserID: ${oldMessage.author.id}`)
.setTimestamp()
msgChannel.send(mEmbed)
}
How would I stop it from sending the embed if a bots message was updated.
Making a really simple check will resolve this issue. In Discord.js there is a user field that tells you if the user is a bot or not.
In fact, it is really recommended you add this in the "onMessage" part of your code as it stops other bots from using your bot, this is to make sure things are safe and no loopbacks/feedbacks happen, either way, you don't want a malicious bot taking advantage of your bot, which can get your bot in trouble too.
Here is what you want to do;
if (message.author.bot) return;
What this code specifically does is check if the message's author is a bot, if it returns true, it will break the code from running, if it returns a false, the code continues running.
You can do the same if you want to listen to bots ONLY by simply adding a exclamation mark before the message.author.bot like this;
if (!message.author.bot) return;
It is also possible to see what other kinds of information something holds, you can print anything to your console. For example, if you want to view what a message object contains, you can print it into your console with;
console.log(message) // This will show everything within that object.
console.log(message.author) // This will show everything within the author object (like ID's, name, discriminators, avatars, etc.)
Go ahead and explore what you can do!
Happy developing! ^ -^
That is really easy to do. All you need to do is check if the author of the message ist a bot and then return if true. You do that like this
if (oldMessage.author.bot) return;

Discord JS v12: How do you get a message's content by it's ID?

I'm relatively new to discord.js, and I've started building a bot project that allows a user to create a message via command, have that message stored in a hidden channel on my private server, and then said message can be extracted through the message ID.
I have the write working and it returns the message ID of the message sent in the hidden channel, but I'm completely stumped on the get command. I've tried searching around online but every method I tried would return errors like "Cannot read property 'fetch' of undefined" or "'channel' is not defined". Here are some examples of what I tried, any help would be appreciated. Note that my args is already accurate, and "args[0]" is the first argument after the command. "COMMAND_CHANNEL" is the channel where the command is being executed while "MESSAGE_DATABASE" is the channel where the targeted message is stored.
let msgValue = channel.messages.cache.get(args[0])
client.channels.cache.get(COMMAND_CHANNEL).send(msgValue.content)
let msgValue = msg.channel.message.fetch(args[0])
.then(message => client.channels.cache.get(COMMAND_CHANNEL).send(msgValue.content))
.catch(console.error);
I even tried using node-fetch to call the discord API itself
const api = require("node-fetch")
let msgValue = api(`https://discordapp.com/api/v8/channels/${MESSAGE_DATABASE}/messages/${args[0]}`)
.then(message => client.channels.cache.get(COMMAND_CHANNEL).send(msgValue.content))
.catch(console.error);
Am I missing something or am I making some sort of mistake?
Edit: Thanks for the help! I finished my bot, it's just a little experimental bot that allows you to create secret messages that can only be viewed through their ID upon executing the command :get_secret_message <message_id>. I posted it on top.gg but it hasn't been approved yet, so in the meantime if anyone wants to mess around with it here is the link: https://discord.com/api/oauth2/authorize?client_id=800368784484466698&permissions=76800&scope=bot
List of commands:
:write_secret_message - Write a secret message, upon execution the bot will DM you the message ID.
:get_secret_message <message_id> - Get a secret message by its ID, upon execution the bot will DM you the message content.
:invite - Get the bot invite link.
NOTE: Your DMs must be turned on or the bot won't be able to DM any of the info.
My test message ID: 800372849155637290
fetch returns the result as promise so you need to use the then to access that value instead of assigning it to a variable (msgValue). Also you made a typo (channel.message -> channel.messages).
I would recommend using something like this:
msg.channel.messages
.fetch(args[0])
.then(message => {
client.channels
.fetch(COMMAND_CHANNEL)
.then(channel => channel.send(message.content))
.catch(console.error)
})
.catch(console.error)
I think you were quite close with the second attempt you posted, but you made one typo and the way you store the fetched message is off.
The typo is you wrote msg.channel.message.fetch(args[0]) but it should be msg.channel.messages.fetch(args[0]) (the typo being the missing s after message). See the messages property of a TextChannel.
Secondly, but this is only a guess really as I can't be sure since you didn't provide much of your code, when you try to fetch the message, you are doing so from the wrong channel. You are trying to fetch the message with a given ID from in the channel the command was executed from (the msg.channel). Unless this command was executed from the "MESSAGE_DATABASE" channel, you would need to fetch the message by ID from the "MESSAGE_DATABASE" channel instead of the msg.channel.
Thirdly, if you fetch a message, the response from the Promise can be used in the .then method. You tried to assign the response to a variable msgValue with let msgValue = msg.channel.message.fetch(args[0]) but that won't do what you'll expect it to do. This will actual assign the entire Promise to the variable. What I think you want to do is just use the respone from the Promise directly in the .then method.
So taking all that, please look at the snippet of code below, with inspiration taken from the MessageManager .fetch examples. Give it a try and see if it works.
// We no longer need to store the value of the fetch in a variable since that won't work as you expect it would.
// Also we're now fetching the message from the MESSAGE_DATABASE channel.
client.channels.cache.get(MESSAGE_DATABASE).fetch(args[0])
// The fetched message will be given as a parameter to the .then method.
.then(fetchedMessage => client.channels.cache.get(COMMAND_CHANNEL).send(fetchedMessage.content))
.catch(console.error);

Get a GuildMember's nickname and status type in Discord.js v12

The title's pretty much everything. I have tried .addField(`**Nickname (If Applicable):**`, `${usr.nickname}`) but it says undefined in the embed... For the presence though, I've tried .addField(`**Status:**`, `${usr.presence}`). That gives me [object Object] in the embed. Can anyone help?
First of all, you're not able to get a GuildMember object's status but would have to first turn it into a user object.
This can be easily done as follows:
const memberObject = <guild>.members.cache.get('place id here') // Gives you the member object
// or alternatively you could search for him using his name using the .find() function
const userObject = memberObject.user // Gives you the user object of the member
From there on, we could simply check the user's nickname and status using:
console.log(userObject.presence.status)
console.log(memberObject.nickname)
Hopefully this helps!

Discord.js, message.guild.owner returns null

I'm coding a server-info command for my discord bot, and I want to get the owner username or tag from the actual guild. I found a way to do it in discord js 11, but it's not working anymore under 12th version :
const guild = client.guilds.get(message.guild.id);
message.channel.send(message.guild.member(guild.owner) ? guild.owner.toString() : guild.owner.user.tag);
// if the user is in that guild it will mention him, otherwise it will use .tag
So in discord js 12, client.guilds.get isn't a function, and guild.owner returns null.
message.guild.owner.user.usernameis also returning Cannot read property 'user' of null.
I took a look at the documentation, and message.guild.owner seems to be a real property (https://discord.js.org/#/docs/main/stable/class/Guild?scrollTo=owner). So I don't know why it's returning null.
I'd recommend that you first get the guild and make sure that it's available before trying to modify or access it. Therefore, your bot won't hit any errors. Additionally, as far as I know, guild.owner returns null but there is a way around this. You can get the guild owner ID through guild.ownerID and fetch the member as a guildMember. Here is the code:
const guild = message.guild; // Gets guild from the Message object
if(!guild.available) return; // Stops if unavailable
await message.guild.members.fetch(message.guild.ownerID) // Fetches owner
.then(guildMember => sOwner = guildMember) // sOwner is the owner
message.channel.send(guild.member(sOwner) ? sOwner.toString() : guild.owner.user.tag);
This is how you would get the owner's tag when you have the guild. This also does not rely on the cache, so if your bot restarts or the cache is cleared, it will work regardless.
let ownerTag = undefined;
<client>.users.fetch(<guild>.ownerID).then(user => ownerTag = user.tag);
.fetch() returns a promise, which is why I declared a variable and then assigned the value to it.
Make sure you enable these intents in your discord developer portal so your bot could access your server
After that, you could access your user owner tag.

Is there a way to add a role to someone without mentioning/pinging them? [discord.js]

Pretty much the title. Every time I try adding a role to someone using this:
const member = message.author;
member.roles.add('732727208774205460');
I end up with this TypeError:
TypeError: Cannot read property 'add' of undefined
However, if I use it like this:
const member = message.mentions.members.first();
member.roles.add('732727208774205460');
It works completely fine. Problem is, that only works if the person I'm adding a role to was mentioned/pinged by the user. I'm trying to add a role to the user himself where the user doesn't ping anyone (for censorship, mainly). Is there a way I could do this without getting the TypeError?
You are receiving an error because message.author.roles is undefined, so trying to use .add() on it causes an error.
message.author is of type User, which represents a discord user, and is not associated with any particular server.
You're looking instead for message.member which has type GuildMember, which represents a particular user's profile inside of a guild (message.member is just message.author but as a GuildMember instead of a User). It is the GuildMember type that has roles.
Solution:
const member = message.member;
member.roles.add('732727208774205460');
Official Documentation:
User,
GuildMember
