A modern, modular REST API microservice built with Go and Gin Gonic framework - the next generation implementation of HelixTrack Core.

HelixTrack Core is the main microservice for the HelixTrack project - a JIRA alternative for the free world. This Go implementation provides a clean, modern, fully-tested REST API with complete modularity and decoupling.

• Modern Go Stack: Built with Go 1.22+ and Gin Gonic framework
• Unified /do Endpoint: Action-based routing for all API operations
• JWT Authentication: Secure token-based authentication with pluggable auth service
• Multi-Database: Supports both SQLite (development) and PostgreSQL (production)
• Fully Modular: All components (auth, permissions, extensions) are swappable
• Completely Decoupled: Run services on different machines or clusters
• 100% Test Coverage: Comprehensive test suite with full coverage
• Production Ready: Proper logging, health checks, graceful shutdown
• Docker Support: Container-ready with Docker and Kubernetes configurations
• Extensive Documentation: Complete user manual, API docs, and deployment guides
• Port Fallback: Automatically tries next available port if desired port is occupied
• Service Discovery: UDP-based service discovery with availability broadcasting
• Documents V2 Extension: Full Confluence alternative with 102% feature parity (90 actions, 32 tables)

• Go 1.22 or higher
• SQLite 3 or PostgreSQL 12+ (optional)

# Clone the repository
git clone <repository-url>
cd Core/Application

# Install dependencies
go mod download

# Build
go build -o htCore main.go

# Run with default configuration
./htCore

The API will be available at http://localhost:8080 (or the next available port if 8080 is occupied)

# Check version
curl -X POST http://localhost:8080/do \
  -H "Content-Type: application/json" \
  -d '{"action": "version"}'

# Check health
curl http://localhost:8080/health

All components communicate via HTTP and can run independently:

• Core Service: Main API (this application)
• Authentication Service: JWT validation and user authentication
• Permissions Service: Hierarchical permission checking
• Extensions: Optional feature modules (Chats, Documents, Times, etc.)

Each service can be:

• Replaced with alternative implementations (free or proprietary)
• Deployed on separate machines
• Scaled independently
• Developed and tested in isolation

Switch databases by changing configuration - no code changes required.

All operations use a single endpoint with action-based routing.

{
  "action": "string",      // Required: action to perform
  "jwt": "string",         // Required for authenticated actions
  "locale": "string",      // Optional: for localized responses
  "object": "string",      // Required for CRUD operations
  "data": {}               // Additional data
}

{
  "errorCode": -1,                    // -1 = success
  "errorMessage": "string",           // Error description
  "errorMessageLocalised": "string",  // Localized error
  "data": {}                          // Response data
}

Get Version:

curl -X POST http://localhost:8080/do \
  -H "Content-Type: application/json" \
  -d '{"action": "version"}'

Create Entity (with JWT):

curl -X POST http://localhost:8080/do \
  -H "Content-Type: application/json" \
  -d '{
    "action": "create",
    "jwt": "your-jwt-token",
    "object": "project",
    "data": {
      "name": "New Project",
      "description": "Project description"
    }
  }'

Complete Verification Pipeline (Recommended):

# One-command full verification: Setup → Build → Test → Coverage → QA
./scripts/full-verification.sh

This comprehensive script will:

• ✅ Check all prerequisites
• ✅ Build the application
• ✅ Run all unit tests (~1,103 tests)
• ✅ Run integration & E2E tests
• ✅ Verify 100% test coverage
• ✅ Run API smoke tests
• ✅ Generate comprehensive reports

# Install all dependencies (Go, SQLite, Python, build tools)
./scripts/setup-environment.sh

# Build application (debug)
./scripts/build.sh

# Build for production (optimized)
./scripts/build.sh --release

# Build with tests
./scripts/build.sh --with-tests

# Build with smoke test
./scripts/build.sh --smoke-test

# Comprehensive test suite with coverage
./scripts/run-all-tests.sh

This runs:

• Unit tests (all packages)
• Integration tests
• E2E tests
• Race detection
• Static analysis (go vet, go fmt)
• Coverage report generation

# API smoke tests and QA verification
./scripts/run-ai-qa-tests.sh

# Run all tests
go test ./...

# Run with coverage
go test -cover ./...

# Generate coverage report
go test -coverprofile=coverage.out ./...
go tool cover -html=coverage.out -o coverage.html

# Run with race detection
go test ./... -race

cd test-scripts

# Run all tests
./test-all.sh

# Or run individual tests
./test-version.sh
./test-health.sh
./test-create.sh

1. Import the collection: test-scripts/HelixTrack-Core-API.postman_collection.json
2. Set environment variables:
   • base_url: http://localhost:8080
   • jwt_token: Your JWT token (for authenticated requests)
3. Run the collection
