graphql-error-logger 0.0.3

Log expection from the GraphQL python server

Summary

• allows for the logging of the exception happening in the flask-graphql framework.

• this hooks into the graphql error handler and logs the original error, along with its stacktrace

• this allows one to see the data for an error like

{
  "errors": [
    {
      "message": "sdsd",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "users"
      ]
    }
  ],
  "data": {
    "users": null
  }
}

Usage

a. using an existing logger in the app.py

import logging

import graphql_error_logger

def create_app():
    # logger initialization and configuration
    logger= logging.getLogger(__name__)
    graphql_error_logger.init_logger(logger)

b. if no logger is provided, the library creates a logger called graphql-error-logger automatically

import graphql_error_logger

def create_app():
    graphql_error_logger.init_logger()

• this logger is configured to use the ERROR log level to log the exception stacktrace
