guide VS dnsguide

Either way, you're going to need to follow either this guide: https://discordjs.guide/ to get you started with DiscordJS (which is IMO the easiest language to learn it in, also usually the most up-to-date). If you're not into reading (which is not in the slightest optimal if you wanna learn how to program) then there's probably some DiscordJS tutorials online. Just search DiscordJS tutorials on youtube and you're sure to find one.

https://discordjs.guide is the "official" discord.js guide, you'll find a command handler there. I don't know if it will be more or less complicated than the one youre using.

Also do some debug logging to show that the target it actually being read correctly. But moving to slash commands may work better. There is a really good guide out there. DiscordJS Guide

Well, I recommend you JavaScript, it is good for beginners and there's a lot of content on internet. Once you understand and practice the basics, you can use discord.js to write your bots. They have a guide website if you are interested.

but I use the official discord.js guide cooldown example: https://github.com/discordjs/guide/blob/main/code-samples/additional-features/cooldowns/index.js

https://discordjs.guide has a good tutorial on slash commands

Official guide from the peeps who made DJS: https://discordjs.guide/

Read the discord js guide (https://discordjs.guide/). The answer to your problem is that it takes many hours for global / commands to register. The reason I still recommend the guide is because it gives you an introduction to many of these topics. It's better than a lot of youtube video tutorials and such.

Check out Building a DNS server in Rust

Building a DNS server in Rust - Emil Hernvall

I made one too https://github.com/ccouzens/dns-packet

The differences:

I followed this guide rather than the RFCs https://github.com/EmilHernvall/dnsguide/blob/master/chapter...

Mine isn't as polished. The command line parsing and output is more thrown together.

I hardcoded the packet identifier (it's not production code, and I'm only looking up one at a time).

I didn't use any bit manipulation libraries. I can see they would help because DNS packets don't line up their information with the byte boundaries.

I highly recommend the Building a DNS server in Rust guide by Emil Hernvall on GitHub. This guide will walk you through how to implement the DNS server and recursive resolve.
