Plugin System Phase 1: Core Plugin Manager Service

🔌 Plugin System - Core Manager Implementation

Overview

Implement the foundational plugin system that allows loading, registering, and managing plugins with TypeScript/JavaScript support.

Technical Requirements

1. Plugin Manager Service (src/services/PluginManager.ts)

• Plugin lifecycle management (install, enable, disable, uninstall)
• Plugin registration and discovery
• Plugin metadata validation
• Plugin dependency resolution
• Error handling and recovery

2. Database Schema

• Create plugins table for plugin metadata
• Create plugin_data table for plugin-specific storage
• Create plugin_marketplace table for future marketplace integration
• Add migration files

3. Plugin Base Classes

• Backend plugin base class (PluginBase)
• Frontend plugin base class (PluginComponentBase)
• Plugin context and SDK interfaces
• Type definitions and interfaces

4. Plugin Loading System

• Dynamic module loading for backend plugins
• React component injection for frontend plugins
• Plugin sandboxing and isolation
• Resource cleanup on unload

Acceptance Criteria

• Plugins can be loaded from the filesystem
• Plugin metadata is validated against schema
• Basic plugin lifecycle events work (install/uninstall/enable/disable)
• Plugin data storage functions correctly
• Error handling prevents system crashes from bad plugins

Dependencies

• Requires completed security hardening (✅ Done in v1.2.0)
• Database integration with Prisma
