72a59bbcdd refactor: Refactor interaction handling and event management 
- Updated interactionCreate event to improve error handling and logging.
- Enhanced ready event to ensure client user is available before proceeding.
- Refactored voiceStateUpdate event for better clarity and error handling.
- Adjusted index.ts to improve client initialization and command/event loading.
- Improved Shoukaku event handling and initialization in ShoukakuEvents.ts.
- Enhanced logger utility for better message formatting.
- Updated TypeScript configuration for better compatibility and strictness.
- Created a new botClient type definition for improved type safety.

# discord-music-bot # Discord Music Bot (TypeScript)
Discord music bot template written in NodeJS using `discord.js` and `erela.js`, with Lavalink support. Discord music bot template written in TypeScript using `discord.js` and `shoukaku`, with Lavalink support.
## Features ## Features
- Slash commands: `/ping`, `/join`, `/play`, `/leave` - Slash commands (e.g., `/ping`, `/join`, `/play`, `/leave`)
- Lavalink integration for audio playback - `shoukaku` integration for robust Lavalink audio playback
- Modular command handler structure - Modular command and event handlers written in TypeScript
- Basic Docker support (`Dockerfile`, `docker-compose.yml`)
- Comprehensive test suite with Jest
## Prerequisites ## Prerequisites
- Node.js (>=14) - Node.js (>=16 recommended, check `package.json` for specific engine requirements)
- pnpm or npm - pnpm (recommended) or npm
- A Discord application with bot token - TypeScript (`typescript` package, usually installed as a dev dependency)
- LavaLink server for audio streaming - A Discord application with bot token and client ID
- A running Lavalink server
## Setup ## Setup
1. Copy `.env.example` to `.env` and fill in your credentials: 1. **Clone the repository:**
```env ```sh
DISCORD_TOKEN=your_discord_bot_token git clone <repository_url>
CLIENT_ID=your_discord_application_id cd discord-music-bot
LAVALINK_HOST=127.0.0.1
LAVALINK_PORT=2333
LAVALINK_PASSWORD=your_lavalink_password
``` ```
2. Install dependencies: 2. **Install dependencies:**
```sh ```sh
pnpm install pnpm install
``` ```
3. Run tests: 3. **Configure Environment:**
```sh Copy `.env.example` to `.env` and fill in your credentials:
pnpm test ```dotenv
# Discord Bot Token (Required)
DISCORD_TOKEN=your_discord_bot_token
# Discord Application Client ID (Required for command deployment)
CLIENT_ID=your_discord_application_id
# Discord Guild ID (Optional, for deploying commands to a specific test server)
# GUILD_ID=your_guild_id_here
# Lavalink Configuration (Required)
LAVALINK_HOST=lavalink # Or 127.0.0.1 if running locally without Docker Compose
LAVALINK_PORT=2333
LAVALINK_PASSWORD=your_lavalink_password
# LAVALINK_SECURE=false # Set to true if Lavalink uses SSL/WSS
# Logging Level (Optional, defaults typically to 'info')
# LOG_LEVEL=info
# YouTube OAuth Token (Optional, needed for YouTube Music via specific plugins)
# See note below on how to obtain this.
YOUTUBE_OAUTH_TOKEN=your_youtube_oauth_token_here
``` ```
4. Register slash commands:
**Note on YouTube OAuth Token:**
The `YOUTUBE_OAUTH_TOKEN` is required by some Lavalink plugins (like the `youtube-plugin` potentially used here) to access YouTube Music tracks directly. Obtaining this involves:
1. Go to the [Google Cloud Console](https://console.cloud.google.com/).
2. Create a new project or select an existing one.
3. Navigate to "APIs & Services" -> "Credentials".
4. Click "Create Credentials" -> "OAuth client ID".
5. Select Application type: **"TVs and Limited Input devices"**.
6. Give it a name (e.g., "Lavalink YouTube Music Access").
7. Click "Create". You'll get a Client ID and Client Secret (you likely won't need the secret directly for the token flow).
8. Follow the on-screen instructions or Google's documentation for the "OAuth 2.0 for TV and Limited Input devices" flow. This usually involves visiting a specific URL with your client ID, getting a user code, authorizing the application on a separate device/browser logged into your Google account, and then exchanging the device code for a **refresh token**.
9. Paste the obtained **refresh token** as the value for `YOUTUBE_OAUTH_TOKEN` in your `.env` file.
4. **Build TypeScript (if needed):**
Many setups use `ts-node` for development, but for production, you might need to compile:
```sh ```sh
pnpm start # or node deploy-commands.js pnpm build # Check package.json for the exact build script
``` ```
5. Start the bot:
5. **Register Slash Commands:**
Run the deployment script (ensure `CLIENT_ID` and `DISCORD_TOKEN` are set in `.env`).
```sh ```sh
pnpm start pnpm deploy # Check package.json for the exact deploy script (might be node/ts-node deploy-commands.ts)
``` ```
6. **Start the Bot:**
```sh
pnpm start # Check package.json for the exact start script (might run compiled JS or use ts-node)
```
## Testing
The project includes a comprehensive test suite using Jest. The tests cover commands, events, and utilities.
### Running Tests
```bash
# Run all tests with coverage report
pnpm test
# Run tests in watch mode during development
pnpm test:watch
# Run tests in CI environment
pnpm test:ci
```
