[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
[![PyPI version](https://badge.fury.io/py/tradata-logger.svg)](https://badge.fury.io/py/tradata-logger)

## Features

- 🚀 **FastAPI Middleware** - Automatic request logging with trace IDs
- 📊 **Structured JSON Logging** - Consistent, searchable log format
- 🔗 **Request Correlation** - Track requests across microservices
- ⚡ **High Performance** - Async-first design with minimal overhead
- 🎯 **Trading-Specific** - Specialized logging for financial applications
- 🔧 **Easy Configuration** - Environment variables and programmatic setup
- 🎭 **Context Management** - Automatic operation and step tracking
- 🏷️ **Decorators** - One-liner logging for API endpoints

## Quick Start

### Installation

**This is a private package accessible only to your GitHub organization.**

#### **Option 1: Automated Setup (Recommended)**
```bash
# Download and run the setup script
curl -O https://raw.githubusercontent.com/your-org/tradata-core-py/main/setup_private_install.sh
chmod +x setup_private_install.sh
./setup_private_install.sh YOUR_GITHUB_TOKEN_HERE
```

#### **Option 2: Manual Installation**
```bash
# Install from private GitHub Packages
pip install tradata-core-py

# Or install directly from private repository
pip install git+https://YOUR_TOKEN@github.com/your-org/tradata-core-py.git
```

**See [Private Package Setup Guide](PRIVATE_PACKAGE_README.md) for detailed instructions.**

### Basic Usage

```python
from tradata_core import get_logger

logger = get_logger("my-service")
await logger.info("Service started", "Service", "Startup")
```

### FastAPI Integration

```python
from fastapi import FastAPI
from tradata_core import LoggingMiddleware

app = FastAPI()
app.add_middleware(LoggingMiddleware)

# Automatic request logging with trace IDs!
```

## Why TradATA Logger?

### For Trading Applications

- **Operation Tracking**: Log business operations (e.g., "QuoteRetrieval", "TradeExecution")
- **Step Monitoring**: Track specific steps within operations (e.g., "Validation", "API_Call")
- **Performance Metrics**: Built-in timing and performance logging
- **Cache Operations**: Specialized logging for cache hits/misses
- **Client Tracking**: Monitor external API usage and performance

### For Microservices

- **Trace ID Propagation**: Follow requests across service boundaries
- **Request Correlation**: Link related operations with unique identifiers
- **Structured Logging**: Consistent JSON format for log aggregation
- **Middleware Integration**: Framework-specific middleware for automatic logging

### For Development Teams

- **Clean APIs**: Decorators and context managers for minimal code
- **Comprehensive Coverage**: Automatic logging of requests, errors, and performance
- **Flexible Configuration**: Environment-based and programmatic configuration
- **Extensible Design**: Easy to add custom formatters and handlers

## Core Concepts

### Operation and Step Tracking

Every log entry includes:
- **Operation**: High-level business operation (e.g., "QuoteRetrieval")
- **Step**: Specific step within the operation (e.g., "API_Call", "Validation")

```python
await logger.info("Quote retrieved", "QuoteRetrieval", "API_Call", symbol="AAPL")
```

### Context Variables

Automatic tracking of:
- **Trace ID**: Unique identifier for request chains
- **Request ID**: Unique identifier for individual requests
- **Client**: External service being used

### Structured Logging

All logs include structured data for easy searching and analysis:

```json
{
  "timestamp": "2024-01-15T10:30:00Z",
  "level": "INFO",
  "message": "Quote retrieved successfully",
  "operation": "QuoteRetrieval",
  "step": "API_Call",
  "trace_id": "trace_12345",
  "request_id": "req_67890",
  "client": "alpaca_api",
  "symbol": "AAPL",
  "duration_ms": 150.5
}
```

## Usage Examples

### Basic Logging

```python
from tradata_core import get_logger

logger = get_logger("quotes-service")

# Basic logging
await logger.info("Processing started", "DataProcessing", "Validation")
await logger.error("API call failed", "ExternalAPI", "Call", error="Connection timeout")

# Specialized logging
await logger.log_cache_operation("Cache_Get", True, "quote:AAPL", 5.0)
await logger.log_client_operation("API_Call", "alpaca_api", "get_quote", 150.0)
```

### API Endpoint Logging

```python
from tradata_logger.utils.decorators import log_endpoint

@app.get("/quotes/{symbol}")
@log_endpoint("/quotes/{symbol}", "quote_retrieval", "quotes_service")
async def get_quote(symbol: str):
    # Automatic logging of request, processing, and response
    return {"symbol": symbol, "price": 150.00}
```

### Context Management

```python
from tradata_logger.utils.context import logging_context

async with logging_context("data_processing", "batch_validation") as ctx:
    ctx.add_context(batch_size=1000, dataset="market_data")
    
    for item in data:
        # Process item
        pass
    
    # Automatic completion logging with duration
```

### FastAPI Middleware

```python
from tradata_core import LoggingMiddleware, PerformanceLoggingMiddleware

app = FastAPI()

# Basic logging middleware
app.add_middleware(LoggingMiddleware)

# Performance-focused middleware
app.add_middleware(PerformanceLoggingMiddleware)
```

## Configuration

### Environment Variables

```bash
LOG_LEVEL=INFO
LOG_FORMAT=json
LOG_INCLUDE_TRACE_ID=true
LOG_PERFORMANCE=true
LOG_CACHE_OPERATIONS=true
```

config = LogConfig(
    level="DEBUG",
    format="console",
    handlers=[
        HandlerConfig(type="console", level="DEBUG"),
        HandlerConfig(type="file", filename="app.log", level="INFO")
    ]
)
```
