Nuxt Discord

A Nuxt module for building Discord bots with slash commands, featuring hot module replacement, automatic command registration, and web interface for command management.

Features

• 🤖 Discord Bot Integration - Seamlessly integrate Discord.js with your Nuxt application
• ⚡ Slash Commands - Type-safe slash command definitions with automatic registration
• 🎯 Auto-sync - Automatically sync commands with Discord's servers
• 🖥️ Web Interface - Beautiful UI for managing and viewing slash commands
• 🔄 Real-time Updates - WebSocket-based live updates in development

Quick Setup

Install the module to your Nuxt application:

pnpm install nuxt-discord discord.js

Add the module to your nuxt.config.ts:

export default defineNuxtConfig({
  modules: ['nuxt-discord'],
  discord: {
    // Discord bot configuration
    client: {
      intents: ['Guilds'], // Discord gateway intents
      deferOnPromise: true, // Auto-defer interactions when command returns a promise
    },
    dir: 'discord', // Directory for Discord-related files
    autoStart: true, // Auto-start the bot on server startup
    watch: {
      enabled: true, // Enable HMR for commands
      port: 5720, // HMR server port
      showURL: false, // Show HMR server URL in console
      sync: {
        debounce: 1000 // Sync delay in milliseconds
      }
    }
  }
})

Set up your environment variables:

# .env
DISCORD_TOKEN=your_bot_token_here
DISCORD_CLIENT_ID=your_application_id_here

Creating Slash Commands

Create slash commands in the /discord/commands directory:

// discord/commands/ping.ts
/**
 * @name ping
 * @description A simple ping command that responds with 'pong!'
 */
export default function ping() {
  return 'pong!'
}

Defining a command this way this module automatically deduces the name and description from the JSDoc comments. The command name is inferred following this set of priorities: describeCommand macro > @name JSDoc tag > function name > file name.

Commands with Parameters

// discord/commands/add.ts
/**
 * @name add
 * @description Adds two numbers together
 * @param a The first number to add
 * @param b The second number to add
 */
export default (a: number, b: number) => {
  // Add parameter validation
  describeOption(a, {
    min: -100,
    max: 100,
  })

  describeOption(b, {
    min: -100,
    max: 100,
  })

  return `The sum of ${a} and ${b} is ${a + b}!`
}

String Parameters with Choices

// discord/commands/greet.ts
/**
 * @name greet
 * @description Greet someone with a custom message
 * @param name The person to greet
 * @param style The greeting style
 */
export default (name: string, style: string) => {
  describeOption(name, {
    minLength: 1,
    maxLength: 32,
  })

  describeOption(style, {
    choices: [
      { name: 'Formal', value: 'formal' },
      { name: 'Casual', value: 'casual' },
      { name: 'Enthusiastic', value: 'enthusiastic' },
    ],
  })

  const greetings = {
    formal: `Good day, ${name}.`,
    casual: `Hey ${name}!`,
    enthusiastic: `HELLO THERE ${name.toUpperCase()}!!! 🎉`,
  } as const

  return greetings[style as keyof typeof greetings]
}

Web Interface

Access the command management interface at /discord/slash-commands in your application. The interface provides:

• 📋 Command Overview - View all registered commands with their parameters
• 🏷️ Parameter Details - See type information, validation rules, and constraints
• 🔄 Sync Commands - Monitor local commands' synced status with server
• ➕ Register Commands - Easily register newly added commands
• ⚡ Live Updates - Real-time updates during development

Coming Soon: Live command execution/testing, i18n support, logging dashboard, and more fine-grained client control

Advanced Usage & Customization

The module is highly customizable and provides access to the internal Discord client and runtime hooks for advanced use cases.

Using the Discord Client in Server

import { useDiscordClient } from '#imports'

export default async () => {
  const client = useDiscordClient()

  // Access the internal Discord.js client
  const discordJS = client.internalClient
  const guilds = discordJS?.guilds.cache.size || 0

  return `Bot is in ${guilds} servers!`
}

Runtime Hooks

The module provides several hooks for customizing bot behavior:

// nitro/plugins/discord-config.ts
export default defineNitroPlugin(async (nitro) => {
  // Configure Discord client options
  nitro.hooks.hook('discord:client:config', (options) => {
    options.presence = {
      status: 'online',
      activities: [{
        name: 'Powered by Nuxt',
      }]
    }
  })

  // Handle client ready event
  nitro.hooks.hook('discord:client:ready', (client) => {
    console.log('Discord bot is ready!')
  })

  // Handle client errors
  nitro.hooks.hook('discord:client:error', (error) => {
    console.error('Discord error:', error)
  })
})

Custom Response Handling

export default (message: string) => {
  // Return different response types
  return reply.ephemeral(`This is private: ${message}`) // Only visible to user
  // or
  return `Public response: ${message}` // Visible to everyone
}

Refer to /src/types.ts for detailed type definitions for how you can define commands return types for advanced behavior.

Configuration Options

// nuxt.config.ts
export default defineNuxtConfig({
  discord: {
    client: {
      intents: [
        'Guilds',
        'GuildMessages'
      ],
      deferOnPromise: true, // Auto-defer interactions when command returns a promise
    },
    dir: 'discord',
    autoStart: true,
    watch: {
      enabled: true,
      port: 5720, // HMR server port
      showURL: false, // Show HMR server URL in console
      sync: {
        debounce: 1000
      }
    }
  }
})

Use the 'nitro:client:config' hook to configure other options passed to the Discord client.
