Implement Event-Based Actions Microservice

[mule-bot]

This PR implements the event-based actions microservice as a standalone Go application that bridges external webhooks to the Mule workflow engine through Supabase.

Key Features Implemented

1. Core Service Infrastructure:

   • HTTP server with Gin framework
   • Configuration management
   • Graceful shutdown handling

2. HTMX Web Interface:

   • Dashboard for monitoring events
   • Configuration page for Supabase and Mule API settings
   • Responsive UI matching existing Mule styling

3. Supabase Integration:

   • Database client for event listening
   • Event processing pipeline
   • Processed event tracking

4. Webhook Processing:

   • Event transformation logic
   • Mule API integration (/v1/chat/completions)
   • Bearer token authentication support

5. Terraform Integration:

   • Embedded Terraform configurations
   • Supabase schema and function definitions

Architecture

External Webhooks → Supabase (via Terraform) → Go Service (DB Listener) → Mule API (/v1/chat/completions)

Testing

The service has been tested to ensure:

• HTTP server starts correctly
• HTML templates render properly
• Configuration loading works
• Supabase client initializes (when credentials provided)
• Event processing pipeline compiles correctly

Next Steps

• Implement Terraform execution functionality
• Add full Supabase real-time listener implementation
• Complete API endpoints for configuration management
• Add comprehensive unit and integration tests
• Implement proper error handling and logging
