-# Rust LavaLink Discord Music Bot Prototype
+# discord-music-bot
 
-A prototype Discord music bot built with Rust, using the [Serenity](https://github.com/serenity-rs/serenity) library for Discord interactions and the [lavalink-rs](https://github.com/adamsoutar/lavalink-rs) crate to interface with a [LavaLink](https://github.com/lavalink-devs/Lavalink) audio server. This bot utilizes slash commands for user interaction and features a modular command structure using the `inventory` crate. It can be run natively or using Docker Compose for easier setup and deployment.
+Discord music bot template written in NodeJS using `discord.js` and `erela.js`, with Lavalink support.
 
 ## Features
 
-* Connects to Discord via the Gateway.
+- Slash commands: `/ping`, `/join`, `/play`, `/leave`  
-* Connects to a LavaLink node for audio processing.
+- Lavalink integration for audio playback  
-* Slash command support for core music functions:
+- Modular command handler structure  
-  * `/join`: Connect the bot to your voice channel.
-  * `/play`: Play audio from a URL or search query (YouTube default). Handles single tracks and playlists.
-  * `/skip`: Skip the currently playing track.
-  * `/leave`: Disconnect the bot from the voice channel.
-* Basic queueing (handled internally by LavaLink).
-* Modular command system using `inventory` for easy addition of new commands.
-* Basic auto-leaving functionality when the bot is alone in a voice channel (with a short delay).
-* Asynchronous architecture using Tokio.
-* Logging using `tracing`.
-* Containerized setup using Docker and Docker Compose.
 
 ## Prerequisites
 
-### For Native Execution
+- Node.js (>=14)  
-
+- pnpm or npm  
-1. **Rust Toolchain:** Install Rust using [rustup](https://rustup.rs/). (`rustup update` recommended).
+- A Discord application with bot token  
-2. **LavaLink Server:**
+- LavaLink server for audio streaming  
-    * Download the latest `Lavalink.jar` from the [LavaLink Releases](https://github.com/lavalink-devs/Lavalink/releases).
-    * A **Java Runtime Environment (JRE)** (Version 11 or higher, 17 recommended) to run the `.jar` file.
-    * Configure the `application.yml` file for LavaLink.
-3. **Discord Bot Application:** (See details below)
-
-### For Docker Execution
-
-1. **Docker & Docker Compose:** Install Docker Desktop (which includes Compose) or Docker Engine and the Docker Compose plugin. See the [official Docker installation guide](https://docs.docker.com/engine/install/).
-2. **LavaLink Server Files:** You still need to download `Lavalink.jar` and create/configure `application.yml` locally, as these will be mounted into the LavaLink container.
-3. **Discord Bot Application:** (See details below)
-
-### Discord Bot Application Details (Common)
-
-* Create a bot application on the [Discord Developer Portal](https://discord.com/developers/applications).
-* Retrieve the **Bot Token**.
-* Enable the **Privileged Gateway Intents**:
-  * `PRESENCE INTENT` (Optional)
-  * `SERVER MEMBERS INTENT` (Optional, not strictly required for prototype)
-  * `MESSAGE CONTENT INTENT` (Optional, not strictly required for prototype)
-  * **`GUILD_VOICE_STATES`** (**Required** for voice functionality)
-* Invite the bot to your Discord server with necessary permissions: `Connect`, `Speak`, `Send Messages`/`Send Messages in Threads`, `Use Application Commands`.
 
 ## Setup
 
-1. **Clone the Repository:**
+1. Copy `.env.example` to `.env` and fill in your credentials:
-
-    ```bash
-    git clone <repository-url>
-    cd discord-music-bot-lavalink-rs
-    ```
-
-2. **Prepare LavaLink Files:**
-    * Download the latest `Lavalink.jar` from [LavaLink Releases](https://github.com/lavalink-devs/Lavalink/releases) and place it in the project root directory.
-    * Create or copy an `application.yml` file into the project root directory. Configure at least the `lavalink.server.password`. Example:
-
-        ```yaml
-        # application.yml
-        server:
-          port: 2333
-          address: 0.0.0.0
-        lavalink:
-          server:
-            password: "youshallnotpass" # CHANGE THIS
-            sources: # Enable desired sources
-              youtube: true
-              soundcloud: true
-        # Add other configurations as needed
-        ```
-
-3. **Configure Environment Variables:**
-    Create a `.env` file in the project root:
-
-    ```bash
-    cp .env.example .env
-    ```
-
-    Edit `.env` with your credentials:
-
    ```env
-    # .env
+   DISCORD_TOKEN=your_discord_bot_token
-    DISCORD_TOKEN=YOUR_BOT_TOKEN_HERE
+   CLIENT_ID=your_discord_application_id
-
+   LAVALINK_HOST=127.0.0.1
-    # --- IMPORTANT: Choose ONE Lavalink Host setting ---
-
-    # == For Docker Compose Execution ==
-    # Use the service name defined in docker-compose.yml
-    LAVALINK_HOST=lavalink
-
-    # == For Native Execution ==
-    # Use the actual IP or hostname of your LavaLink server
-    # LAVALINK_HOST=127.0.0.1 # Or e.g., other-machine-ip
-
-    # --- Common Settings ---
    LAVALINK_PORT=2333
-    LAVALINK_PASSWORD=youshallnotpass # Must match password in application.yml
+   LAVALINK_PASSWORD=your_lavalink_password
+   ```
+2. Install dependencies:
+   ```sh
+   pnpm install
+   ```
+3. Run tests:
+   ```sh
+   pnpm test
+   ```
+4. Register slash commands:
+   ```sh
+   pnpm start # or node deploy-commands.js
+   ```
+5. Start the bot:
+   ```sh
+   pnpm start
    ```
 
-    **Note:** Ensure the `LAVALINK_PASSWORD` here matches the one in `application.yml`.
+## Docker
 
-## Running the Bot
+A `Dockerfile` and `docker-compose.yml` are provided for containerized deployment.
 
-You can run the bot natively or using Docker Compose.
+- Build and run with Docker Compose:
-
+  ```sh
-### Option 1: Running with Docker Compose (Recommended)
+  docker-compose up --build
-
-This method runs both the bot and the LavaLink server in isolated containers.
-
-1. **Ensure Prerequisites:** Docker, Docker Compose, `Lavalink.jar`, `application.yml`, configured `.env` (with `LAVALINK_HOST=lavalink`).
-2. **Build and Start:** In the project root, run:
-
-    ```bash
-    docker compose up --build -d
   ```
-
+- Environment variables are loaded from `.env`.  
-    * `--build`: Builds the bot image. Needed the first time or after code changes.
+- Lavalink service is configured in `docker-compose.yml` alongside the bot.
-    * `-d`: Runs containers in the background.
-3. **Check Logs (Optional):**
-
-    ```bash
-    docker compose logs -f app      # View bot logs
-    docker compose logs -f lavalink   # View LavaLink logs
-    ```
-
-    Press `Ctrl+C` to stop following.
-4. **Stopping:**
-
-    ```bash
-    docker compose down
-    ```
-
-### Option 2: Running Natively
-
-This method requires you to run LavaLink separately.
-
-1. **Start LavaLink:**
-    Navigate to the directory containing `Lavalink.jar` and `application.yml`. Run:
-
-    ```bash
-    java -jar Lavalink.jar
-    ```
-
-    Keep this terminal open.
-2. **Build the Bot (if needed):**
-
-    ```bash
-    cargo build --release
-    ```
-
-3. **Configure `.env`:** Ensure `LAVALINK_HOST` in your `.env` file points to the correct IP/hostname where LavaLink is running (e.g., `127.0.0.1` if running on the same machine).
-4. **Run the Bot:**
-    In a **new terminal**, navigate to the project root and run:
-
-    ```bash
-    # Using cargo
-    cargo run
-    # Or using the compiled release binary
-    # target/release/discord-music-bot-lavalink-rs
-    ```
-
-## Available Commands
-
-Use these commands in your Discord server where the bot is present:
-
-* `/join` : Makes the bot join the voice channel you are currently in.
-* `/play query:<url or search term>` : Plays a song from a URL (direct link or playlist) or searches YouTube for the term and plays the first result. Queues subsequent tracks/playlists.
-* `/skip` : Skips the song currently playing.
-* `/leave` : Disconnects the bot from the voice channel.
