handler = logging.StreamHandler()
handler.setFormatter(loggingx.JSONFormatter())

# loggingx.basicConfig(level=loggingx.INFO, handlers=[handler])
logging.basicConfig(level=logging.INFO, handlers=[handler])

if __name__ == "__main__":
    with loggingx.addFields(ctx="ctx"):
        # loggingx.info("test", extra={"extra": "extra"})
