Installation

Logger Kit is available on PyPI and can be installed with Poetry:

# Using Poetry (recommended)
poetry add logger-kit

# Using pip
pip install logger-kit

Quick Start

from logger_kit import Logger

# Create a logger instance
logger = Logger(name="app", level="INFO")

# Basic logging
logger.info("Hello, World!")

# Structured logging with additional context
logger.info("User logged in", extra={
    "user_id": 123,
    "ip": "192.168.1.1",
    "status": "success"
})

# Using context manager for temporary settings
with logger.context(level="DEBUG"):
    logger.debug("This is a debug message")

# Async logging
async def main():
    await logger.ainfo("Processing task", extra={"task_id": "123"})
    await logger.adebug("Task details", extra={"details": "..."})

Data Masking

Protect sensitive information with advanced data masking:

logger = Logger(name="secure_app")

# Configure masking rules
logger.key_masker.set_default_mask("[MASKED]")
logger.key_masker.add_exact_match("password")
logger.key_masker.add_exact_match("api_key", "[REDACTED]")
logger.key_masker.add_pattern("email", r"[^@]+@[^@]+\.[^@]+")

# Logging with sensitive data (will be automatically masked)
logger.info("User data", extra={
    "user": {
        "email": "[e-mail]",
        "password": "secret123",
        "api_key": "ak_test_12345"
    }
})
