Delete command or "trigger word" message - discord

I have a message I want our bot to send but, in order to keep the chat clean, I'd like to delete the message that invoked the command: how can I do this?
This is the current code for the message:
if (message.content.toLowerCase().includes("<#botsnumberidhere> what are the numbers")) {
message.channel.send("This is good, real good.", {
file: "https://domainforimage.com/image0.jpg" // Or replace with FileOptions object
});
}

You can delete the message with Message.delete(). Please note that this will tell Discord that you want to delete the message, but you'll still be able to access the properties of the message variable you previously stored.
if (message.content.toLowerCase().includes("<#botsnumberidhere> what are the numbers")) {
message.delete(); // You can put it here.
message.channel.send("This is good, real good.", {
file: "https://domainforimage.com/image0.jpg"
});
}

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, só 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 check if message contains emojis discord.js

I need to check if a message sent by user contains emojis because my database can't store this type of data. So I thought that I'll use a message.content.match() or message.content.includes() but when I use it, it still is not enough. I was thinking about making something like blacklist but for emojis and then I realized that I need to save a blacklist of all emojis so I gave up on that. My question for you is, do you know any easier way to make this? I was searching for solution to my problem but I didn't find anything.
Thank you a lot for any help.
if(message.author.id!='botid' && message.author.id===userdbId && message.content.match(/<a?:.+?:\d+>/)){
const name = args.join(" ");
const username = name.slice(0);
conn.query(`UPDATE users SET ignick='`+username+`' WHERE userID='${message.author.id}'`);
console.log(username);
message.channel.send("success message");
conn.end(err => {
if(err){
throw error;
}
console.log('Disconnected from database');
})
}
else{
console.log('bot has been stopped from adding his message to database');
}```
At top of this code i made a connect function and two constructors to pull from database userId
Whenever an emote is used in a message, it follows this format: <:OmegaStonks:723370807308582943>, where the name of the emote is "OmegaStonks" and the id links to the link to the image, like so: https://cdn.discordapp.com/emojis/723370807308582943.png
Detecting this pattern is pretty easy using regex.
<a?:.+?:\d+>
which takes any character from the first : to the second : (and I used a ? to make the wildcard . stop as soon as possible). You also can't have colons in emote names, so it won't abruptly stop there.

Here is how you could do it
client.on('message', msg => {
if(msg.content.match(/<a?:.+?:\d+>/)) return; //or whatever action(s) you want to do
})

How do I find the content of a message that a user replied to in discord

I'm currently developing a bot that pins messages in a text file to bypass the message pin limit in discord servers, and my system works by having a user reply to a message with -pin and it will save that message and the message author in a text file. The problem is that I don't know how to get the content of the replied to message and the author of said message. Any help would be appreciated.
if(command === 'pin'){
message.channel.send('Ok, pinning that. Use -seepins to see all the pins.'),
//i have no clue how to get the message that was replied to please help let pinned =
//im begging you please i have no idea let pinnedauthor = message.
fs.writeFile('messages.txt', pinned + ' written by ' + pinnedauthor + '\n', (err) => {
if (err) throw err;
});
}
this is what I currently have. I just need to find out how to get the two things mentioned in the first paragraph and it should work.
Any help is appreciated, and thank you for reading this through.
When you receive the message object, you have a variable named reference. If your message is a reply reference should not be null and contains the ids of channelID, guildID, messageID.
With this you can then get the message content of the previous message with a line that looks like
client.on('message', async message => {
const repliedTo = await message.channel.messages.fetch(message.reference.messageID);
console.log(repliedTo.content);
});
Just be careful with the message.reference.messageID you have to add error handling to avoid crash when looking for an undefined variable.

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;

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');
});
