casavo-log-formatter 1.0.2

A pre-configured JSON formatter for the Casavo logging format

casavo-log-formatter

An utility library that exposes a pre-configured log formatter for the Casavo JSON logging format.

Installation

pip install casavo-log-formatter, or pip install casavo-log-formatter[orjson] if you prefer using orjson as a json serializer.

Usage

Referring to https://docs.python.org/3/library/logging.config.html#logging-config-dictschema, we suggest to configure your logging dictConfig by adding those 2 keys:

formatters = {
    "simple": {
        "format": "%(levelname)s %(message)s",
        "datefmt": "%H:%M:%S",
    },
    "standard": {
        "class": "casavo_log_formatter.formatters.CasavoJsonFormatter"
    },
}

handlers = {
    "stdout": {
        "level": "DEBUG",
        "class": "logging.StreamHandler",
        "formatter": "standard"
        if settings.ENVIRONMENT in ["staging", "production"]  # or whatever you use to specify the env
        else "simple",
    },
}

This will configure a simple log format for dev and the fully featured formatter for staging + dev.
