This repo defines the JSON log module. This module overrides the python root logger to output logs as json dictionaries. The intent is that this will be used as the default log formatter throughout services .

A project using this package should include this line in the requirements file:
git@github.com:saffronblueai/json-log.git
If the project is using a constraints file to manage private package locations, the requirements file should instead include:
jsonlog
and the constraints file should include:
jsonlog@git@git@github.com:saffronblueai/json-log.git
An example of how to use the logger is shown below. This is an extract from an application using FastAPI, Mangum, and AWS Lambda. In this case, if the application is run locally it will still configure the logger but without the AWS context.
import logging
from fastapi import FastAPI
from jsonlog.utils import configure_logging
from mangum import Mangum
logger = logging.getLogger(__name__)
def get_application() -> FastAPI:
app = FastAPI()
if os.getenv("LAMBDA_TASK_ROOT") is None:
configure_logging()
return app
app = get_application()
def handler(event, context):
configure_logging(context)
logger.info("Called with event", extra=event)
asgi_handler = Mangum(app)
return asgi_handler(event, context)
