Log-Schema

This logging utility library utilizes python's standard logging library and logging.config to help setup logging. Use the command below to easily setup logging for a project.

Usage

The default setup for logging adheres to the best practice guidelines described here.

import log_schema 
import logging

log_schema.setup_logging()
logging.info("Hello")

# Output: {"timestamp": "2026-04-08T22:58:22.677137Z", "level": "INFO", "message": "Hello"}

The examples directory in this project contains additional examples on other features such as:

• Setup logging from a config (logging.config)
• Setup logging with dynamic fields
• Adding additional handlers with correct format

Implementation Notes

• If using a custom config file, the fields in model will overwrite the static_fields set in the config ONLY IF the formatters explicitly reference log_schema.DefaultFormatter AND contains the same field key.

• Each handler has its own formatter. Any additional handlers added to the root logger needs to redefine the formatter. This can easily be done by using the DefaultFormatter with the same model used for setup. Alternatively, you can make new models for different handlers.

  new_handler.setFormatter(DefaultFormatter(models="<whatever model used for setup"))
