# Discord Bot Architect

Specialized skill for building production-ready Discord bots.
Covers Discord.js (JavaScript) and Pycord (Python), gateway intents,
slash commands, interactive components, rate limiting, and sharding.

## Principles

- Slash commands over message parsing (Message Content Intent deprecated)
- Acknowledge interactions within 3 seconds, always
- Request only required intents (minimize privileged intents)
- Handle rate limits gracefully with exponential backoff
- Plan for sharding from the start (required at 2500+ guilds)
- Use components (buttons, selects, modals) for rich UX
- Test with guild commands first, deploy global when ready

## 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

```javascript
// 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);
```

```javascript
// 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`);
  }
};
```

```javascript
// src/events/interactionCreate.js
const { Events } = require('discord.js');

module.exports = {
  name: Events.InteractionCreate,
  async execute(interaction) {
    if (!interaction.isChatInputCommand()) return;

    const command = interaction.client.commands.get(interaction.commandName);
    if (!command) {
      console.error(`No command matching ${interaction.commandName}`);
      return;
    }

    try {
      await command.execute(interaction);
    } catch (error) {
      console.error(error);
      const reply = {
        content: 'There was an error executing this command!',
        ephemeral: true
      };

      if (interaction.replied || interaction.deferred) {
        await interaction.followUp(reply);
      } else {
        await interaction.reply(reply);
      }
    }
  }
};
```

```javascript
// src/deploy-commands.js
const { REST, Routes } = require('discord.js');
const fs = require('node:fs');
const path = require('node:path');
require('dotenv').config();

const commands = [];
const commandsPath = path.join(__dirname, 'commands');
const commandFiles = fs.readdirSync(commandsPath).filter(f => f.endsWith('.js'));

for (const file of commandFiles) {
  const command = require(path.join(commandsPath, file));
  commands.push(command.data.toJSON());
}

const rest = new REST().setToken(process.env.DISCORD_TOKEN);

(async () => {
  try {
    console.log(`Refreshing ${commands.length} commands...`);

    // Guild commands (instant, for testing)
    // const data = await rest.put(
    //   Routes.applicationGuildCommands(CLIENT_ID, GUILD_ID),
    //   { body: commands }
    // );

    // Global commands (can take up to 1 hour to propagate)
    const data = await rest.put(
      Routes.applicationCommands(process.env.CLIENT_ID),
      { body: commands }
    );

    console.log(`Successfully registered ${data.length} commands`);
  } catch (error) {
    console.error(error);
  }
})();
```

### 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

```python
# 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"])
```

```python
# cogs/general.py
import discord
from discord.ext import commands

class General(commands.Cog):
    def __init__(self, bot):
        self.bot = bot

    @commands.slash_command(name="info", description="Bot information")
    async def info(self, ctx: discord.ApplicationContext):
        embed = discord.Embed(
            title="Bot Info",
            description="A helpful Discord bot",
            color=discord.Color.blue()
        )
        embed.add_field(name="Servers", value=len(self.bot.guilds))
        embed.add_field(name="Latency", value=f"{round(self.bot.latency * 1000)}ms")
        await ctx.respond(embed=embed)

    @commands.Cog.listener()
    async def on_member_join(self, member: discord.Member):
        # Requires Members intent (PRIVILEGED)
        channel = member.guild.system_channel
        if channel:
            await channel.send(f"Welcome {member.mention}!")

def setup(bot):
    bot.add_cog(General(bot))
```

### Interactive Components Pattern

Using buttons, select menus, and modals for rich UX

**When to use**: Need interactive user interfaces,Collecting user input beyond slash command options,Building menus, confirmations, or forms

```javascript
// Discord.js - Buttons and Select Menus
const {
  SlashCommandBuilder,
  ActionRowBuilder,
  ButtonBuilder,
  ButtonStyle,
  StringSelectMenuBuilder,
  ModalBuilder,
  TextInputBuilder,
  TextInputStyle
} = require('discord.js');

module.exports = {
  data: new SlashCommandBuilder()
    .setName('menu')
    .setDescription('Shows an interactive menu'),

  async execute(interaction) {
    // Button row
    const buttonRow = new ActionRowBuilder()
      .addComponents(
        new ButtonBuilder()
          .setCustomId('confirm')
          .setLabel('Confirm')
          .setStyle(ButtonStyle.Primary),
        new ButtonBuilder()
          .setCustomId('cancel')
          .setLabel('Cancel')
          .setStyle(ButtonStyle.Danger),
        new ButtonBuilder()
          .setLabel('Documentation')
          .setURL('https://discord.js.org')
          .setStyle(ButtonStyle.Link)  // Link buttons don't emit events
      );

    // Select menu row (one per row, takes all 5 slots)
    const selectRow = new ActionRowBuilder()
      .addComponents(
        new StringSelectMenuBuilder()
          .setCustomId('select-role')
          .setPlaceholder('Select a role')
          .setMinValues(1)
          .setMaxValues(3)
          .addOptions([
            { label: 'Developer', value: 'dev', emoji: '💻' },
            { label: 'Designer', value: 'design', emoji: '🎨' },
            { label: 'Community', value: 'community', emoji: '🎉' }
          ])
      );

    await interaction.reply({
      content: 'Choose an option:',
      components: [buttonRow, selectRow]
    });

    // Collect responses
    const collector = interaction.channel.createMessageComponentCollector({
      filter: i => i.user.id === interaction.user.id,
      time: 60_000  // 60 seconds timeout
    });

    collector.on('collect', async i => {
      if (i.customId === 'confirm') {
        await i.update({ content: 'Confirmed!', components: [] });
        collector.stop();
      } else if (i.customId === 'cancel') {
        await i.update({ content: 'Cancelled', components: [] });
        collector.stop();
      } else if (i.customId === 'select-role') {
        await i.update({ content: `You selected: ${i.values.join(', ')}` });
      }
    });
  }
};
```

```javascript
// Modals (forms)
module.exports = {
  data: new SlashCommandBuilder()
    .setName('feedback')
    .setDescription('Submit feedback'),

  async execute(interaction) {
    const modal = new ModalBuilder()
      .setCustomId('feedback-modal')
      .setTitle('Submit Feedback');

    const titleInput = new TextInputBuilder()
      .setCustomId('feedback-title')
      .setLabel('Title')
      .setStyle(TextInputStyle.Short)
      .setRequired(true)
      .setMaxLength(100);

    const bodyInput = new TextInputBuilder()
      .setCustomId('feedback-body')
      .setLabel('Your feedback')
      .setStyle(TextInputStyle.Paragraph)
      .setRequired(true)
      .setMaxLength(1000)
      .setPlaceholder('Describe your feedback...');

    modal.addComponents(
      new ActionRowBuilder().addComponents(titleInput),
      new ActionRowBuilder().addComponents(bodyInput)
    );

    // Show modal - MUST be first response
    await interaction.showModal(modal);
  }
};

// Handle modal submission in interactionCreate
if (interaction.isModalSubmit()) {
  if (interaction.customId === 'feedback-modal') {
    const title = interaction.fields.getTextInputValue('feedback-title');
    const body = interaction.fields.getTextInputValue('feedback-body');

    await interaction.reply({
      content: `Thanks for your feedback!\n**${title}**\n${body}`,
      ephemeral: true
    });
  }
}
```
