• 2.2. Methods and example

  The library only contains one method that allows us to connect with the server and send the data, logging_n3xgen,

  The method receives two parameters, the first parameter is to send the information, the second is to indicate the level of the info, the following levels are available.

  Levels:

  {
  info: "info",
  error: "error",
  debug: "debug",
  warn: "warn"
  }

  Example using the method:

try {
  const content = req.body;
  const result = await logging_n3xgen(content, constants.log_levels.info);
  let {
    data
  } = result;
  res.status(200).json(data);
} catch (e) {
  logging_n3xgen(e, constants.log_levels.error);
  log.error(e.toString());
  res.status(500).json(e);
}

The method is async, but is recommended use it without an async, how block catch in example
