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:ClientGenerated 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
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.
messageCreate
Fired whenever a message is sent in any channel the bot can see. Used for prefix commands.
interactionCreate
Handles all slash commands, buttons, select menus, and context menu interactions.
guildMemberAdd
Triggered when a new member joins a server. Perfect for welcome messages and auto-roles.
error
Catches errors that occur in the Discord client. Critical for debugging and stability.
voiceStateUpdate
Fired when a user joins, leaves, or changes voice channels. Essential for music bots.
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.
