Discord Bot Architect

# Discord Bot Architect

Patterns

Discord.js v14 Foundation

Modern Discord bot setup with Discord.js v14 and slash commands

**When to use**: ['Building Discord bots with JavaScript/TypeScript', 'Need full gateway connection with events', 'Building bots with complex interactions']

// src/index.js

const { Client, Collection, GatewayIntentBits, Events } = require('discord.js');

const fs = require('node:fs');

const path = require('node:path');

require('dotenv').config();

// Create client with minimal required intents

const client = new Client({

intents: [

GatewayIntentBits.Guilds,

// Add only what you need:

// GatewayIntentBits.GuildMessages,

// GatewayIntentBits.MessageContent, // PRIVILEGED - avoid if possible

]

});

// Load commands

client.commands = new Collection();

const commandsPath = path.join(__dirname, 'commands');

const commandFiles = fs.readdirSync(commandsPath).filter(f => f.endsWith('.js'));

for (const file of commandFiles) {

const filePath = path.join(commandsPath, file);

const command = require(filePath);

if ('data' in command && 'execute' in command) {

client.commands.set(command.data.name, command);

}

}

// Load events

const eventsPath = path.join(__dirname, 'events');

const eventFiles = fs.readdirSync(eventsPath).filter(f => f.endsWith('.js'));

for (const file of eventFiles) {

const filePath = path.join(eventsPath, file);

const event = require(filePath);

if (event.once) {

client.once(event.name, (...args) => event.execute(...args));

} else {

client.on(event.name, (...args) => event.execute(...args));

}

}

client.login(process.env.DISCORD_TOKEN);

// src/commands/ping.js

const { SlashCommandBuilder } = require('discord.js');

module.exports = {

data: new SlashCommandBuilder()

.setName('ping')

.setDescription('Replies with Pong!'),

async execute(interaction) {

const sent = await interaction.reply({

content: 'Pinging...',

fetchReply: true

});

const latency = sent.createdTimestamp - interaction.createdTimestamp;

await interaction.editReply(`Pong! Latency: ${latency}ms`);

}

};

// src/events/interactionCreate.js

const { Events } = require('discord.js');

module.exports = {

name: Event

### Pycord Bot Foundation

Discord bot with Pycord (Python) and application commands

**When to use**: ['Building Discord bots with Python', 'Prefer async/await patterns', 'Need good slash command support']

# main.py
import os
import discord
from discord.ext import commands
from dotenv import load_dotenv

load_dotenv()

# Configure intents - only enable what you need
intents = discord.Intents.default()
# intents.message_content = True  # PRIVILEGED - avoid if possible
# intents.members = True          # PRIVILEGED

bot = commands.Bot(
    command_prefix="!",  # Legacy, prefer slash commands
    intents=intents
)

@bot.event
async def on_ready():
    print(f"Logged in as {bot.user}")
    # Sync commands (do this carefully - see sharp edges)
    # await bot.sync_commands()

# Slash command
@bot.slash_command(name="ping", description="Check bot latency")
async def ping(ctx: discord.ApplicationContext):
    latency = round(bot.latency * 1000)
    await ctx.respond(f"Pong! Latency: {latency}ms")

# Slash command with options
@bot.slash_command(name="greet", description="Greet a user")
async def greet(
    ctx: discord.ApplicationContext,
    user: discord.Option(discord.Member, "User to greet"),
    message: discord.Option(str, "Custom message", required=False)
):
    msg = message or "Hello!"
    await ctx.respond(f"{user.mention}, {msg}")

# Load cogs
for filename in os.listdir("./cogs"):
    if filename.endswith(".py"):
        bot.load_extension(f"cogs.{filename[:-3]}")

bot.run(os.environ["DISCORD_TOKEN"])
