# ROA2WEB - Modern ERP Reports Application

**FastAPI Backend + Vue.js 3 Frontend + Telegram Bot**

Modern microservices-based ERP reporting application for managing invoices, payments, and financial data with Oracle database integration.

---

## Project Overview

ROA2WEB is a comprehensive financial reporting platform built with modern technologies:

- **Backend**: FastAPI (Python) - High-performance async API
- **Frontend**: Vue.js 3 + PrimeVue - Rich, responsive web interface
- **Telegram Bot**: Alternative command-based interface
- **Database**: Oracle Database with connection pooling
- **Architecture**: Microservices with shared components

---

## Quick Start

### Prerequisites

- Python 3.11+
- Node.js 16+
- Oracle Database access
- SSH access to Oracle server (for development)

### Development Setup

```bash
# Clone repository
git clone <repository-url>
cd roa2web

# Start all services with one command
./start-dev.sh
```

This starts SSH tunnel, backend (port 8001), and frontend (port 3000-3005).

**For individual service setup or troubleshooting**: See "Development & Testing" section below or component-specific READMEs.

### Access the Application

- **Frontend**: http://localhost:3000 (or 3001-3005 if 3000 is busy)
- **Backend API Docs**: http://localhost:8001/docs (Swagger UI)
- **Backend ReDoc**: http://localhost:8001/redoc
- **Health Check**: http://localhost:8001/health

### Key Features

- **Shared Database Pool**: Singleton Oracle connection pool shared across microservices
- **Two-Tier Cache System**: Hybrid L1 (Memory) + L2 (SQLite) for optimal performance
- **JWT Authentication**: Secure token-based auth with middleware
- **Microservices**: Independent services with clear separation of concerns
- **Oracle Integration**: Direct Oracle stored procedure calls with caching
- **Responsive Design**: Mobile-friendly Vue.js interface
- **Telegram Integration**: Alternative bot-based interface

*See `CLAUDE.md` for detailed tech stack information, cache system, and architecture decisions.*

## Development & Testing

**Quick Start**: Use `./start-dev.sh` to start all services (SSH tunnel + Backend + Frontend).

**For detailed development commands, testing procedures, and troubleshooting**: See `CLAUDE.md` and component-specific READMEs:
- Backend: `reports-app/backend/README.md`
- Frontend: `reports-app/frontend/README.md` & `reports-app/frontend/tests/README.md`
- Telegram Bot: `reports-app/telegram-bot/README.md`

**Key Commands**:
```bash
# Production/Development
./start-dev.sh start                               # Start all services (production SSH tunnel + Backend + Frontend + Telegram Bot)
./ssh_tunnel.sh start                              # Start Oracle DB tunnel only (production: 10.0.20.36)

# Testing/Validation (uses Oracle TEST server - LXC 10.0.20.121)
./start-test.sh start                              # Start all testing services (TEST SSH tunnel + Backend + Frontend + Telegram Bot)
./ssh-tunnel-test.sh start                         # Start Oracle TEST tunnel only (testing: LXC 10.0.20.121)

# Individual Services
cd reports-app/backend && uvicorn app.main:app --reload  # Backend (port 8001)
cd reports-app/frontend && npm run dev             # Frontend (port 3000-3005)
cd reports-app/telegram-bot && python -m app.main  # Telegram Bot (port 8002)
```

**Note**: For automated testing and validation (`/validate` command), use `start-test.sh` which starts all services connected to Oracle TEST server (LXC 10.0.20.121) with test credentials.

**API Documentation** (when backend running):
- Swagger UI: http://localhost:8001/docs
- ReDoc: http://localhost:8001/redoc
- Health Check: http://localhost:8001/health

## Production Deployment

ROA2WEB supports two deployment architectures:

### 🐧 Linux/Docker Deployment
```bash
./setup_production.sh              # Initial setup
./scripts/deploy.sh                # Deploy application
./scripts/health-check.sh          # Health monitoring
```

### 🪟 Windows/IIS Deployment

**Modern Unified Workflow** (recommended):
```powershell
# On Development Machine (WSL/Linux)
cd deployment/windows/scripts
.\Publish-And-Deploy.ps1           # Build + Transfer to server (interactive menu)

# On Windows Server (PowerShell as Admin)
cd deployment/windows/scripts
.\ROA2WEB-Console.ps1              # Deploy + Manage services (interactive console)
```

**Alternative - Manual Installation**:
```powershell
# First-time installation
.\Install-ROA2WEB.ps1
.\Install-TelegramBot.ps1

# Automated deployment
.\Check-And-Deploy.ps1
```
