n8n Kodi Node

A powerful and intelligent n8n node for interacting with Kodi media centers via JSON-RPC API. This node automatically discovers available methods and provides a user-friendly interface for executing Kodi commands.

✨ Features

🚀 Automatic Method Discovery

• Smart Introspection: Automatically discovers all available Kodi methods via JSON-RPC introspection
• Method Parsing: Intelligently parses complex Kodi API structures to extract actual methods
• Real-time Updates: Always shows the latest methods available on your Kodi instance
• No Hardcoding: Adapts to any Kodi version or configuration automatically

🎯 Three Operation Modes

1. Discover Methods: Automatically find all available Kodi methods and their descriptions
2. Execute Method: Run any discovered method with dynamic parameter generation
3. Raw Request: Send custom JSON-RPC requests for advanced users

🔧 Dynamic Parameter Generation

• Smart Parameter Detection: Automatically identifies method parameters and return types
• User-Friendly Interface: Select parameters from dropdowns instead of manual entry
• Parameter Descriptions: Shows detailed information about each parameter
• Default Values: Pre-configured with sensible defaults (e.g., ID: n8n)

🎨 Enhanced User Experience

• Method Filtering: Easy method selection with full descriptions
• Parameter Validation: Built-in parameter type checking and validation
• Debug Information: Real-time debugging and method information display
• Error Handling: Comprehensive error messages and fallback options

📋 Prerequisites

• n8n: Version 1.0 or higher
• Kodi: Any version with JSON-RPC enabled
• Network Access: n8n must be able to reach your Kodi instance

🚀 Installation

Option 1: npm (Recommended)

npm install n8n-nodes-kodi

Option 2: Manual Installation

1. Clone this repository
2. Run npm install
3. Run npm run build
4. Copy the dist folder to your n8n custom nodes directory

⚙️ Configuration

1. Kodi Credentials

Create a new credential type with:

• Host: Your Kodi IP address or hostname
• Port: Kodi HTTP port (default: 8080)
• Username: HTTP username (if enabled)
• Password: HTTP password (if enabled)

2. Node Setup

1. Add the Kodi node to your workflow
2. Select your Kodi credentials
3. Choose the operation mode
4. Configure method and parameters

📖 Usage

Operation 1: Discover Methods

Use this to see all available methods on your Kodi instance:

• Automatically discovers methods via JSONRPC.Introspect
• Shows method names, descriptions, and parameter information
• Updates in real-time based on your Kodi configuration

Operation 2: Execute Method

Execute any discovered method with dynamic parameters:

1. Select Method: Choose from the discovered methods
2. Configure Parameters: Use the dynamic parameter interface
3. Add Parameters: Click "Add Parameter" to see available options
4. Set Values: Enter parameter values as needed
5. Execute: Run the method and see results

Operation 3: Raw Request

For advanced users who need custom JSON-RPC requests:

• Send any valid JSON-RPC request
• Useful for testing or custom implementations
• Full control over request format and parameters

🔍 Dynamic Parameter System

The node automatically generates parameter options based on discovered method information:

• Parameter Names: Select from available parameters for the chosen method
• Parameter Types: See parameter types and descriptions
• Default Values: Sensible defaults are provided where possible
• Validation: Built-in parameter validation and error checking

📚 Common Use Cases

Media Library Management

• Scan video/audio libraries
• Get media information
• Update library metadata

Playback Control

• Play/pause/stop media
• Control volume and seeking
• Get player status

System Management

• Get system information
• Control power states
• Manage addons

File Operations

• Browse file systems
• Get file information
• Navigate media directories

Key Components

• Method Discovery: Intelligent parsing of Kodi JSON-RPC introspection
• Parameter Generation: Dynamic parameter creation based on method definitions
• Error Handling: Comprehensive error handling with custom error types
• Type Safety: Full TypeScript implementation with proper type definitions

🔧 Technical Details

JSON-RPC Introspection

The node uses Kodi's built-in JSONRPC.Introspect method to:

• Discover all available API methods
• Extract method parameters and return types
• Parse complex nested API structures
• Handle different Kodi versions automatically

Method Parsing Algorithm

1. Primary Parsing: Extract methods from standard introspection paths
2. Fallback Parsing: Use recursive search for complex structures
3. Parameter Extraction: Parse parameter definitions and types
4. Method Consolidation: Combine related method information

Error Handling

• Custom Error Types: KodiError for Kodi-specific errors
• Graceful Fallbacks: Continue operation even if some features fail
• User Feedback: Clear error messages and debugging information
• Retry Logic: Automatic retry for transient failures
