A simple, no-fuss logging setup for Python applications

Fast Logger

A simple, no-fuss logging setup for Python applications with sensible defaults.

Features

• Zero configuration: Works out of the box with sensible defaults
• Rotating file logs: Automatically manages log file sizes and backups
• Console output: Simultaneous logging to file and console
• Flexible configuration: Easy to customize when needed
• Type hints: Full type hint support for better IDE experience
• No dependencies: Uses only Python standard library

Installation

pip install python-fast-logger

Quick Start

Super Simple Usage

from fast_logger import quick_logger

logger = quick_logger("my_app")
logger.info("Hello, world!")
logger.error("Something went wrong!")

Basic Usage

from fast_logger import get_logger

logger = get_logger("my_app")
logger.info("Application started")
logger.warning("This is a warning")
logger.error("This is an error")

Advanced Usage

from fast_logger import FastLogger

# Custom configuration
logger = FastLogger(
    name="my_advanced_app",
    level="DEBUG",
    log_folder="custom_logs",
    max_file_size_mb=100,
    backup_count=5,
    console_output=True
)

logger.info("Advanced logging setup complete")
logger.debug("Debug information")

Web Application Example

from fast_logger import get_logger
from flask import Flask

app = Flask(__name__)
logger = get_logger("web_app", level="INFO")

@app.route("/")
def home():
    logger.info("Home page accessed")
    return "Hello, World!"

@app.route("/api/data")
def get_data():
    try:
        # Your API logic here
        data = {"status": "success"}
        logger.info("Data retrieved successfully")
        return data
    except Exception as e:
        logger.error(f"Error retrieving data: {e}")
        return {"status": "error"}, 500

Configuration Options

Parameter	Type	Default	Description
name	str	Required	Logger name (used as filename)
level	str/int	INFO	Logging level (DEBUG, INFO, WARNING, ERROR, CRITICAL)
log_folder	str	logs	Directory name for log files
max_file_size_mb	int	50	Maximum size of each log file in MB
backup_count	int	3	Number of backup files to keep
console_output	bool	True	Whether to output to console
log_format	str	Default format	Custom log format string
base_path	str	Caller's directory	Base directory for logs

Default Log Format

2024-01-15 10:30:45,123 - my_app [main.py:15] - INFO - Hello, world!

File Structure

By default, logs are created in a logs folder relative to your script:

your_project/
├── main.py
└── logs/
    ├── my_app.log
    ├── my_app.log.1
    └── my_app.log.2

API Reference

FastLogger Class

The main class for advanced usage with full configuration options.

logger = FastLogger(
    name="my_app",
    level="INFO",
    log_folder="logs",
    max_file_size_mb=50,
    backup_count=3,
    console_output=True,
    log_format=None,
    base_path=None
)

Convenience Functions

• quick_logger(name, level="INFO"): Minimal setup for immediate use
• get_logger(name, **kwargs): Returns FastLogger instance with fluent interface
• setup_logger(name, **kwargs): Returns standard logging.Logger instance

Why Fast Logger?

Most Python applications need logging, but setting it up properly requires boilerplate code:

• Creating formatters
• Setting up file handlers
• Configuring rotation
• Adding console output
• Managing log directories

Fast Logger eliminates this boilerplate while providing sensible defaults that work for most applications.

Comparison with Standard Logging

Standard logging setup:

import logging
import os
from logging.handlers import RotatingFileHandler

# 15+ lines of boilerplate code...
logger = logging.getLogger("my_app")
logger.setLevel(logging.INFO)
# ... more setup code

Fast Logger:

from fast_logger import quick_logger

logger = quick_logger("my_app")
# Done! 

Requirements

• Python 3.9+
• No external dependencies
