thynogger

A simple and easy to use logging package for better readability in the consoles or terminals. The terminal/console logs can be piped into the file and converted into the CSV file by changing the delimiter to pipe ( | ) symbol.

Motivation

thynogger is designed to be simple logging library with better readability in the terminals. Each thynogger logger can be configured at different levels using the LOG_LEVEL environment variable.

thynogger aims to provide the simple and uni-directional solution to the logging in servers. The logging format is fixed but it provides the flexibility in choosing the levels of the log.
