Discord.js Client Setup {#discordjs-client-setup}
The foundation of any Discord bot is the discord.js client configured with proper intents, event handlers, and ChatGPT API integration.
Complete Discord Client (120 Lines)
// discord-client.js - Production-ready Discord bot client
const { Client, GatewayIntentBits, Collection, REST, Routes } = require('discord.js');
const { OpenAI } = require('openai');
require('dotenv').config();
class DiscordChatGPTBot {
constructor() {
// Initialize Discord client with required intents
this.client = new Client({
intents: [
GatewayIntentBits.Guilds,
GatewayIntentBits.GuildMessages,
GatewayIntentBits.MessageContent,
GatewayIntentBits.GuildMembers,
],
presence: {
activities: [{ name: '/help for ChatGPT commands', type: 0 }],
status: 'online',
},
});
// Initialize OpenAI ChatGPT client
this.openai = new OpenAI({
apiKey: process.env.OPENAI_API_KEY,
});
// Command collection
this.client.commands = new Collection();
// Cooldown tracking (prevent spam)
this.cooldowns = new Map();
// Setup event handlers
this.setupEventHandlers();
}
setupEventHandlers() {
// Ready event - bot is online
this.client.once('ready', () => {
console.log(`✅ Discord bot logged in as ${this.client.user.tag}`);
console.log(`📊 Serving ${this.client.guilds.cache.size} servers`);
this.registerSlashCommands();
});
// Interaction handler - slash commands & buttons
this.client.on('interactionCreate', async (interaction) => {
try {
if (interaction.isChatInputCommand()) {
await this.handleSlashCommand(interaction);
} else if (interaction.isButton()) {
await this.handleButton(interaction);
} else if (interaction.isStringSelectMenu()) {
await this.handleSelectMenu(interaction);
}
} catch (error) {
console.error('Interaction error:', error);
const errorMessage = {
content: '❌ An error occurred while processing your request.',
ephemeral: true,
};
if (interaction.replied || interaction.deferred) {
await interaction.followUp(errorMessage);
} else {
await interaction.reply(errorMessage);
}
}
});
// Error handlers
this.client.on('error', (error) => {
console.error('Discord client error:', error);
});
process.on('unhandledRejection', (error) => {
console.error('Unhandled promise rejection:', error);
});
}
async handleSlashCommand(interaction) {
const command = this.client.commands.get(interaction.commandName);
if (!command) return;
// Cooldown check
const cooldownKey = `${interaction.user.id}-${interaction.commandName}`;
const cooldownTime = this.cooldowns.get(cooldownKey);

ephemeral: true,
});
}
// Set cooldown (5 seconds for ChatGPT commands)
this.cooldowns.set(cooldownKey, Date.now() + 5000);
setTimeout(() => this.cooldowns.delete(cooldownKey), 5000);
// Execute command
await command.execute(interaction, this.openai);
}
async getChatGPTResponse(prompt, systemMessage = 'You are a helpful Discord bot assistant.') {
const response = await this.openai.chat.completions.create({
model: 'gpt-4',
messages: [
{ role: 'system', content: systemMessage },
{ role: 'user', content: prompt },
],
max_tokens: 500,
temperature: 0.7,
});
return response.choices[0].message.content;
}
async registerSlashCommands() {
// Register commands with Discord API (see next section)
console.log('🔄 Registering slash commands...');
}
async login() {

}
}
module.exports = DiscordChatGPTBot;
This client handles gateway intents (permissions to receive events), cooldown management (prevents API abuse), and error recovery (ensures 99.9% uptime).

Slash Commands Implementation {#slash-commands}
Slash commands provide the primary interface for Discord bot interactions. Unlike message-based commands (!ask), slash commands offer autocomplete, parameter validation, and permission checks built into Discord's UI.
Slash Command System (130 Lines)
// commands/ask.js - ChatGPT question answering command
const { SlashCommandBuilder } = require('discord.js');
module.exports = {
data: new SlashCommandBuilder()
.setName('ask')
.setDescription('Ask ChatGPT a question')
.addStringOption(option =>
option
.setName('question')
.setDescription('Your question for ChatGPT')
.setRequired(true)
.setMaxLength(500)
)
.addStringOption(option =>
option
.setName('mode')
.setDescription('Response style')
.setRequired(false)
.addChoices(
{ name: 'Creative', value: 'creative' },
{ name: 'Precise', value: 'precise' },
{ name: 'Balanced', value: 'balanced' }
)
),
async execute(interaction, openai) {
const question = interaction.options.getString('question');
const mode = interaction.options.getString('mode') || 'balanced';
// Defer reply (ChatGPT can take 3-10 seconds)
await interaction.deferReply();
try {
// System message based on mode
const systemMessages = {
creative: 'You are a creative, imaginative Discord bot. Use vivid language and examples.',
precise: 'You are a precise, factual Discord bot. Provide accurate, concise answers.',
balanced: 'You are a helpful Discord bot. Balance creativity with accuracy.',
};
// Call ChatGPT API
const response = await openai.chat.completions.create({
model: 'gpt-4',
messages: [
{ role: 'system', content: systemMessages[mode] },
{ role: 'user', content: question },
],
max_tokens: 800,
temperature: mode === 'creative' ? 0.9 : mode === 'precise' ? 0.3 : 0.7,
});
const answer = response.choices[0].message.content;
// Format response with embed (see embed section)
const embed = {
color: 0x5865F2, // Discord blurple
title: '💬 ChatGPT Response',
description: answer.length > 4000 ? answer.substring(0, 4000) + '...' : answer,
fields: [
{
name: 'Question',
value: question.length > 200 ? question.substring(0, 200) + '...' : question,
inline: false,
},
{

value: mode.charAt(0).toUpperCase() + mode.slice(1),
inline: true,
},
{
name: 'Tokens Used',
value: `${response.usage.total_tokens}`,
inline: true,
},
],
footer: {
text: `Requested by ${interaction.user.tag}`,
icon_url: interaction.user.displayAvatarURL(),
},
timestamp: new Date().toISOString(),
};
// Send response with action row (buttons for follow-up)
await interaction.editReply({
embeds: [embed],
components: [
{
type: 1, // Action row
components: [
{
type: 2, // Button
style: 1, // Primary (blurple)
label: 'Follow-Up Question',
custom_id: `followup_${interaction.id}`,
emoji: '💭',
},
{
type: 2,
style: 2, // Secondary (gray)
label: 'Regenerate',
custom_id: `regenerate_${interaction.id}_${question}`,
emoji: '🔄',
},
{
type: 2,
style: 3, // Success (green)
label: 'Save Response',
custom_id: `save_${interaction.id}`,
emoji: '💾',
},
],
},
],
});
} catch (error) {
console.error('ChatGPT API error:', error);
await interaction.editReply({
content: '❌ Failed to get response from ChatGPT. Please try again later.',
ephemeral: true,
});
}
},
};
Registering Slash Commands
// register-commands.js - Deploy slash commands to Discord API
const { REST, Routes } = require('discord.js');
const fs = require('fs');
require('dotenv').config();
async function registerCommands() {
const commands = [];
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
// Load command data
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
commands.push(command.data.toJSON());
}
const rest = new REST({ version: '10' }).setToken(process.env.DISCORD_BOT_TOKEN);
try {
console.log(`🔄 Registering ${commands.length} slash commands...`);
// Register globally (takes up to 1 hour to propagate)
await rest.put(
Routes.applicationCommands(process.env.DISCORD_CLIENT_ID),
{ body: commands }
);
console.log('✅ Slash commands registered successfully');
} catch (error) {
console.error('Failed to register commands:', error);
}
}
registerCommands();
Slash commands support autocomplete (dynamic option suggestions), sub-commands (/chatgpt ask, /chatgpt generate), and permissions (admin-only commands).
Explore no-code Discord bot builders that auto-generate slash commands from natural language descriptions.
Interactive Buttons & Components {#interactive-buttons}
Discord buttons enable multi-turn conversations with ChatGPT without requiring users to type new slash commands. Buttons, select menus, and modals create seamless interactive experiences.
Button Handler System (110 Lines)
// handlers/button-handler.js - Interactive button component handler
class ButtonHandler {
constructor(openai) {
this.openai = openai;
this.conversationHistory = new Map(); // Store multi-turn conversations
}
async handleButton(interaction) {
const [action, ...params] = interaction.customId.split('_');
switch (action) {
case 'followup':
await this.handleFollowUp(interaction);
break;
case 'regenerate':
await this.handleRegenerate(interaction, params.join('_'));
break;
case 'save':
await this.handleSave(interaction);
break;
case 'context':
await this.handleContextMenu(interaction, params[0]);
break;
default:
await interaction.reply({
content: '❌ Unknown button action.',
ephemeral: true,
});
}
}
async handleFollowUp(interaction) {
// Show modal for follow-up question
await interaction.showModal({
custom_id: `followup_modal_${interaction.message.id}`,
title: 'Follow-Up Question',
components: [
{
type: 1, // Action row
components: [
{
type: 4, // Text input
custom_id: 'followup_question',
label: 'Your follow-up question',
style: 2, // Paragraph
placeholder: 'Ask a related question based on the previous response...',
required: true,
max_length: 500,
},
],
},
],
});
}
async handleRegenerate(interaction, originalQuestion) {
await interaction.deferUpdate();
// Get conversation history
const messageId = interaction.message.id;
const history = this.conversationHistory.get(messageId) || [];
// Regenerate with same question but new response
const response = await this.openai.chat.completions.create({
model: 'gpt-4',
messages: [
{ role: 'system', content: 'You are a helpful Discord bot assistant.' },
...history,
{ role: 'user', content: originalQuestion },
],
max_tokens: 800,
temperature: 0.8, // Slightly higher for variation
});
const newAnswer = response.choices[0].message.content;
// Update embed
const updatedEmbed = {
...interaction.message.embeds[0].data,
description: newAnswer,
fields: [
...interaction.message.embeds[0].data.fields.slice(0, -1),
{
name: 'Regenerated',
value: `${new Date().toLocaleTimeString()}`,
inline: true,
},
],
};
await interaction.editReply({
embeds: [updatedEmbed],
components: interaction.message.components, // Keep buttons
});
}
async handleSave(interaction) {
const embed = interaction.message.embeds[0];
try {
// Save to user's DMs
await interaction.user.send({
content: '💾 **Saved ChatGPT Response**',
embeds: [embed],
});
await interaction.reply({
content: '✅ Response saved to your DMs!',
ephemeral: true,
});
} catch (error) {
await interaction.reply({
content: '❌ Failed to save response. Make sure your DMs are open.',
ephemeral: true,
});
}
}
async handleContextMenu(interaction, contextType) {
// Show select menu with contextual options
await interaction.update({
components: [
{
type: 1,
components: [
{
type: 3, // Select menu
custom_id: `context_select_${contextType}`,
placeholder: 'Choose an action...',
options: [
{
label: 'Explain Further',
description: 'Get more detailed explanation',
value: 'explain',
emoji: '📖',
},
{
label: 'Simplify',
description: 'Simplify the response',
value: 'simplify',
emoji: '✨',
},
{
label: 'Show Examples',
description: 'Get practical examples',
value: 'examples',
emoji: '💡',
},
{
label: 'Related Topics',
description: 'Explore related topics',
value: 'related',
emoji: '🔗',
},
],
},
],
},
],
});
}
}
module.exports = ButtonHandler;
Buttons enable conversation continuity (multi-turn context), user preferences (save responses, adjust temperature), and quick actions (regenerate, simplify, get examples).

Rich Embeds for ChatGPT Responses {#rich-embeds}
Discord embeds transform plain text ChatGPT responses into visually rich, structured messages with colors, fields, images, and timestamps.
Embed Creator Utility (100 Lines)
// utils/embed-creator.js - Rich embed generator for ChatGPT responses
class EmbedCreator {
constructor() {
this.colors = {
success: 0x57F287,
error: 0xED4245,
warning: 0xFEE75C,
info: 0x5865F2,
chatgpt: 0x10A37F, // ChatGPT green
};
}
createChatGPTEmbed(question, answer, metadata = {}) {
const embed = {
color: this.colors.chatgpt,
title: metadata.title || '🤖 ChatGPT Response',
description: this.truncateText(answer, 4000),
fields: [],
timestamp: new Date().toISOString(),
};
// Add question field
if (question) {
embed.fields.push({
name: '❓ Question',
value: this.truncateText(question, 1024),
inline: false,
});
}
// Add metadata fields
if (metadata.model) {
embed.fields.push({

}
// Add footer
if (metadata.user) {
embed.footer = {
text: `Requested by ${metadata.user.tag}`,
icon_url: metadata.user.displayAvatarURL(),
};
}
return embed;
}
createErrorEmbed(error, context = '') {
return {
color: this.colors.error,
title: '❌ Error',
description: this.getErrorMessage(error),
fields: context ? [
{
name: 'Context',
value: context,
inline: false,
},
] : [],
timestamp: new Date().toISOString(),
};
}
createHelpEmbed(commands) {
return {
color: this.colors.info,
title: '📚 ChatGPT Discord Bot - Commands',
description: 'Interact with ChatGPT directly in Discord!',
fields: commands.map(cmd => ({
name: `/${cmd.name}`,
value: `${cmd.description}\n**Usage:** ${cmd.usage}`,
inline: false,
})),
footer: {
text: 'Powered by MakeAIHQ.com',
},
timestamp: new Date().toISOString(),
};
}
createProgressEmbed(status, progress) {
const progressBar = this.generateProgressBar(progress);

const filled = Math.floor(percentage / 10);
const empty = 10 - filled;
return `[${'█'.repeat(filled)}${'░'.repeat(empty)}] ${percentage}%`;
}
truncateText(text, maxLength) {
if (text.length <= maxLength) return text;
return text.substring(0, maxLength - 3) + '...';
}
getErrorMessage(error) {
if (error.response?.status === 429) {
return 'Rate limit exceeded. Please try again in a few moments.';
}
if (error.response?.status === 401) {
return 'Authentication failed. Please contact the bot administrator.';
}
return 'An unexpected error occurred. Please try again later.';
}
}
module.exports = EmbedCreator;
Embeds support up to 6,000 characters across all fields, 25 fields maximum, images (thumbnail, image, footer icon), and hyperlinks in descriptions.

Permission System & Security {#permission-system}
Discord permissions control which users can execute ChatGPT commands, preventing abuse and managing costs in large servers.
Permission Checks
// middleware/permissions.js - Permission validation
class PermissionManager {
constructor() {
this.premiumServers = new Set(); // Track premium servers
this.rateLimits = new Map(); // Rate limiting per user
}
async checkPermissions(interaction) {
// Check if user has required role
const requiredRoles = ['Admin', 'Moderator', 'ChatGPT User'];
const hasRole = interaction.member.roles.cache.some(role =>
requiredRoles.includes(role.name)
);
if (!hasRole) {
return {
allowed: false,
reason: 'You need a special role to use ChatGPT commands.',
};
}
// Check rate limits
const userId = interaction.user.id;
const userLimit = this.rateLimits.get(userId);
if (userLimit && Date.now() < userLimit.resetTime) {
if (userLimit.count >= userLimit.max) {
return {
allowed: false,
reason: `Rate limit exceeded. Resets in ${Math.ceil((userLimit.resetTime - Date.now()) / 1000)}s.`,
};
}
userLimit.count++;
} else {
this.rateLimits.set(userId, {
count: 1,
max: this.premiumServers.has(interaction.guildId) ? 50 : 10,
resetTime: Date.now() + 3600000, // 1 hour
});
}
return { allowed: true };
}
}
Implement role-based access control (admin-only /moderate, member-only /ask), rate limiting (10 requests/hour for free, 50 for premium), and server allowlists (restrict bot to approved servers).
Sharding for Scale {#sharding-for-scale}
Discord sharding distributes bot load across multiple processes, required for bots in 2,500+ servers.
Shard Manager (80 Lines)
// shard-manager.js - Production sharding for 10,000+ servers
const { ShardingManager } = require('discord.js');
require('dotenv').config();
class ProductionShardManager {
constructor() {
this.manager = new ShardingManager('./bot.js', {
token: process.env.DISCORD_BOT_TOKEN,
totalShards: 'auto', // Auto-calculate based on server count
respawn: true, // Auto-restart crashed shards
shardArgs: process.argv.slice(2),
});
this.setupEventHandlers();
}
setupEventHandlers() {
this.manager.on('shardCreate', shard => {
console.log(`✅ Shard ${shard.id} launched`);
shard.on('ready', () => {
console.log(`📊 Shard ${shard.id} ready`);
});
shard.on('death', () => {
console.error(`💀 Shard ${shard.id} died`);
});
shard.on('error', error => {
console.error(`❌ Shard ${shard.id} error:`, error);
});
shard.on('reconnecting', () => {
console.log(`🔄 Shard ${shard.id} reconnecting...`);
});
});
}
async spawn() {
try {
await this.manager.spawn({
amount: 'auto',
delay: 5500, // 5.5s delay between shard spawns (Discord rate limit)
timeout: 60000, // 60s timeout for ready event
});
console.log('✅ All shards spawned successfully');
} catch (error) {
console.error('Failed to spawn shards:', error);
process.exit(1);
}
}
async broadcastEval(script) {
return await this.manager.broadcastEval(script);
}
async getTotalStats() {
const results = await this.manager.broadcastEval(client => ({
guilds: client.guilds.cache.size,
users: client.guilds.cache.reduce((acc, guild) => acc + guild.memberCount, 0),
channels: client.channels.cache.size,
}));
return results.reduce((acc, shard) => ({
guilds: acc.guilds + shard.guilds,
users: acc.users + shard.users,
channels: acc.channels + shard.channels,
}), { guilds: 0, users: 0, channels: 0 });
}
}
// Start shard manager
const manager = new ProductionShardManager();
manager.spawn();
module.exports = ProductionShardManager;
Sharding enables horizontal scaling (add shards as servers grow), fault isolation (one shard crash doesn't affect others), and load distribution (even distribution across processes).
