I don't really understand the registering slash commands part of the guide

It says to put this code
const { REST, Routes } = require('discord.js');
const { clientId, guildId, token } = require('./config.json');
const fs = require('node:fs');
const path = require('node:path');

const commands = [];
// Grab all the command folders from the commands directory you created earlier
const foldersPath = path.join(__dirname, 'commands');
const commandFolders = fs.readdirSync(foldersPath);

for (const folder of commandFolders) {
// Grab all the command files from the commands directory you created earlier
const commandsPath = path.join(foldersPath, folder);
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));
// Grab the SlashCommandBuilder#toJSON() output of each command's data for deployment
for (const file of commandFiles) {
const filePath = path.join(commandsPath, file);
const command = require(filePath);
if ('data' in command && 'execute' in command) {
commands.push(command.data.toJSON());
} else {
console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
}
}
}

// Construct and prepare an instance of the REST module
const rest = new REST().setToken(token);

// and deploy your commands!
(async () => {
try {
console.log(`Started refreshing ${commands.length} application (/) commands.`);

// The put method is used to fully refresh all commands in the guild with the current set
const data = await rest.put(
Routes.applicationGuildCommands(clientId, guildId),
{ body: commands },
);

console.log(`Successfully reloaded ${data.length} application (/) commands.`);
} catch (error) {
// And of course, make sure you catch and log any errors!
console.error(error);
}
})();
const { REST, Routes } = require('discord.js');
const { clientId, guildId, token } = require('./config.json');
const fs = require('node:fs');
const path = require('node:path');

const commands = [];
// Grab all the command folders from the commands directory you created earlier
const foldersPath = path.join(__dirname, 'commands');
const commandFolders = fs.readdirSync(foldersPath);

for (const folder of commandFolders) {
// Grab all the command files from the commands directory you created earlier
const commandsPath = path.join(foldersPath, folder);
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));
// Grab the SlashCommandBuilder#toJSON() output of each command's data for deployment
for (const file of commandFiles) {
const filePath = path.join(commandsPath, file);
const command = require(filePath);
if ('data' in command && 'execute' in command) {
commands.push(command.data.toJSON());
} else {
console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
}
}
}

// Construct and prepare an instance of the REST module
const rest = new REST().setToken(token);

// and deploy your commands!
(async () => {
try {
console.log(`Started refreshing ${commands.length} application (/) commands.`);

// The put method is used to fully refresh all commands in the guild with the current set
const data = await rest.put(
Routes.applicationGuildCommands(clientId, guildId),
{ body: commands },
);

console.log(`Successfully reloaded ${data.length} application (/) commands.`);
} catch (error) {
// And of course, make sure you catch and log any errors!
console.error(error);
}
})();
inside a deploy-commands.js script

then on another page, it says to put this code in index.js
client.commands = new Collection();

const foldersPath = path.join(__dirname, 'commands');
const commandFolders = fs.readdirSync(foldersPath);

for (const folder of commandFolders) {
const commandsPath = path.join(foldersPath, folder);
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const filePath = path.join(commandsPath, file);
const command = require(filePath);
// Set a new item in the Collection with the key as the command name and the value as the exported module
if ('data' in command && 'execute' in command) {
client.commands.set(command.data.name, command);
} else {
console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
}
}
}
client.commands = new Collection();

const foldersPath = path.join(__dirname, 'commands');
const commandFolders = fs.readdirSync(foldersPath);

for (const folder of commandFolders) {
const commandsPath = path.join(foldersPath, folder);
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const filePath = path.join(commandsPath, file);
const command = require(filePath);
// Set a new item in the Collection with the key as the command name and the value as the exported module
if ('data' in command && 'execute' in command) {
client.commands.set(command.data.name, command);
} else {
console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
}
}
}
and some of that code looks the same as the first script I sent

What don’t you understand? Do you get an error when running that code or what do you want to know?

I don't understand why it says here to put this code in index.js

but here it says to put almost the exact same code in deploy-commands.js

https://discordjs.guide/creating-your-bot/command-handling.html#loading-command-files This guide from the official website doesn’t say anything about an deploy commands file

Imagine a guide... that explores the many possibilities for your discord.js bot.

On the "Registering slash commands" page it does

They do both go through all commands in the commands folder, but the deploy commands script registers the command to discord, while the index.js script only adds said commands to a Collection in the client

I'm also a noob, but what I understood till now is initializing slash commands (this is done by the deploy-command.js) for your bot in Discord is a separate process then running them (this is done in the index.js). Due to this you might initialize commands in a deploy-command.js, for which you don't have a function yet in index.js. So you could see the command in Discord, but it would throw an error if you click on it. The tutorial solves this elegantly by having the initialization code together with the executable code. This is why they run through the same folders. The deploy-commands uses the data: part of the slashcommandbuilder, and index.js the async execute(interaction) {} part. I hope I'm somewhat correct 😄 PS: my little struggle: if you want to change the initialization parameters for your slash command (for example: you addStringOptions in the data: part), then you will need to run deploy-commands.js for them to be visible in discord.
