Event Handler Generator

Generate Discord.js and Discord.py event listener code for all Discord events and interactions. Build event handlers with proper error handling and best practices.

Event Configuration

Event Parameters

client:Client
The client instance

Generated Code

Ready Handler

// Ready Event Handler
// Emitted when the client becomes ready to start working

client.on('ready', async (client) => {
  try {
    // Your code here
    console.log('Ready event triggered');

  } catch (error) {
    console.error('Error in ready event:', error);
  }
});

💡 Quick Tips

Always wrap event handlers in try-catch blocks to prevent crashes
Use async/await for asynchronous operations in event handlers
Be careful with message events - they can be triggered frequently
Some events require specific intents to be enabled in your bot

Common Discord Events

Essential events every Discord bot should handle

🤖

ready

Triggered when the bot successfully connects to Discord and is ready to receive events.

Essential for bot startup
💬

messageCreate

Fired whenever a message is sent in any channel the bot can see. Used for prefix commands.

Requires MESSAGE_CONTENT intent
🎯

interactionCreate

Handles all slash commands, buttons, select menus, and context menu interactions.

Modern command handling
👋

guildMemberAdd

Triggered when a new member joins a server. Perfect for welcome messages and auto-roles.

Requires GUILD_MEMBERS intent
⚠️

error

Catches errors that occur in the Discord client. Critical for debugging and stability.

Important for production bots
🔊

voiceStateUpdate

Fired when a user joins, leaves, or changes voice channels. Essential for music bots.

Requires GUILD_VOICE_STATES intent

Required Gateway Intents

Some events require specific intents to be enabled in your bot

MESSAGE_CONTENT

Required to read message content in messageCreate, messageUpdate, and related events.

intents: [GatewayIntentBits.MessageContent]

GUILD_MEMBERS

Required for member join/leave events and accessing member lists.

intents: [GatewayIntentBits.GuildMembers]

GUILD_PRESENCES

Required for presence updates (status, activity) of guild members.

intents: [GatewayIntentBits.GuildPresences]

GUILD_VOICE_STATES

Required for voice state updates when users join/leave voice channels.

intents: [GatewayIntentBits.GuildVoiceStates]

Event Handler Best Practices

Use Try-Catch Blocks

Always wrap event handler code in try-catch blocks to prevent your bot from crashing on errors.

Use Async/Await

Make event handlers async and use await for asynchronous operations like sending messages or fetching data.

Filter Bot Messages

In message events, check if the author is a bot to prevent infinite loops and unnecessary processing.

Log Important Events

Log critical events and errors to help with debugging and monitoring your bot's behavior.

⚠️

Be Mindful of Rate Limits

Don't send too many messages or make too many API calls in event handlers. Use cooldowns and queues.

⚠️

Optimize Heavy Events

Events like messageCreate can fire frequently. Keep handler logic efficient and avoid heavy computations.
