Discord js getting a bot's message - discord.js

Well i need to do this:
on a channel a bot announces "btc" price (not real)
im trying to get the price and send the price to a specificed channel
My code
sa.on("message", (message) => {
if (message.content.startsWith("๐ŸŸ ")) {
if (message.author.id == "974187708933083157") {
client.channels.get('955536998989447249').send(`${message.content}`);
} else message.channel.send(``);
}
})
So if a message that starts with ๐ŸŸ  the bot needs to get the price and send it to the channel (955536998989447249)
But it not working my bot is working fine but not getting price and sendimg it

Firstly don't try sending empty message message.channel.send(``);, it will just throw an error.
The main problem, is that client.channels (ChannelManager) doesn't have a "get" method.
Assuming you are using djs v13, to get a channel, you can get it from cache with:
client.channels.cache.get('955536998989447249').send("sth")
however this might not always work if the channel is not currently cached.
Other option is to fetch it, though it is an asynchronous operation, so it looks a bit different:
client.channels.fetch('955536998989447249').then(channel => channel.send("sth"))

Message object .edit() stops working after some time

First I create an object
var queue = {1:{},2:{},3:{}};
And then I store the message based on QueueKey, or edit if it's already created
if (typeof queue[QueueKey].messageOBJ == 'undefined')
{
queue[QueueKey].messageOBJ = await configChannel.send({ embeds: [getEmbedFloor(QueueKey)] });
}
else
{
queue[QueueKey].messageOBJ = await queue[QueueKey].messageOBJ.edit({ embeds: [getEmbedFloor(QueueKey)] });
}
everything starts working well but after sometime(1~2 hours) bot stops editing the already created message, looks like it lose object reference.
It not pops any error message or code break, seems like the message was edited sucessfully but the real message in discord still the same
I'm thinking in store the messageID instead the whole object and search for the message ID with .fetch() but this will lead to other problems
is there any way to store message Objects properly?
I discovered my problem, actually bot was editing the message to frequently, so after some time discord "auto ban" my bot for some time, something like a cooldown, sรณ it starts to get slower and slower, up to seems like it is stuck.
My solution was check message before edit, to compare if the changes in message are really necessary, before edit or not

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);

How to get a Discord bot to send a message to a specfic channel when created?

I'm making a bot which on a react to a certain will create a channel...
That all works perfectly expect I want a nessage to be posted when the cahnnel is created which has a specfic beginning.
client.on('channelCreate', (channel, message) => {
if(channel.name.startsWith('ticket-')){
message.channel.send('test');
});
I'm not getting any errors, just nothing...
You can't use the message variable in the channelCreate event. The only thing you're receiving is a channel object, so you need to use channel.send():
client.on('channelCreate', (channel, message) => {
if(channel.name.startsWith('ticket-')){
channel.send('test');
});

how to send a message to every channel in every guild?

similar to this question however I want to be able to send it to every channel it has access to!
inside the on message event after I verify myself by ID and the issued command I was using this code:
const listedChannels = [];
msg.guild.channels.forEach(channel => {
//get all channels
client.channels.get(channel.id).send("you like bred? (message) ");
//send a message to every channel in this guild
});
however I get the error that .send is not a function...
I have been told to use .send after getting the ID of the channels
If you are looping through all of the channels, you simpily need to send your content to the channel, which you've already gotten from msg.guild.channels.forEach(channel => {//code}).
Replace what you have inside the .forEach block with;
channel.send("You like bred? (message)");
Although this will send You like bred? (message)
If you're trying to get a response back, perhaps look at this answer that explains collecting responses via reactions to a discord message.
The following explanation pertains only to v11 (stable).
Client.channels is a Collection of Channels your bot is watching. You can only send messages to text channels, and this Collection will include DM channels as well. For this reason, we can use Collection.filter() to retrieve a new Collection of only text channels within a guild. Finally, you can iterate over the channels and call TextChannel.send() on each. Because you're dealing with Promises, I'd recommend a Promise.all()/Collection.map() combination (see hyperlinked documentation).
For example...
// assuming "client" is your Discord Bot
const channels = client.channels.filter(c => c.guild && c.type === 'text');
Promise.all(channels.map(c => c.send('Hello, world!')))
.then(msgs => console.log(`${msgs.length} successfully sent.`))
.catch(console.error);
You can use client.channels for this. Check if channel type is guild text channel and then try send a message.
client.channels.forEach(channel => {
if(channel.type === 'text') channel.send('MSG').catch(console.error)
})
