config

You may pass config to the constructor, or set log level with setter.

const config: LoggerConfig = {
  level: Levels.DEBUG, // minimum shown log level 
  transport: ({message}: TransportData) => console.log(message), // transport function or array of functions
  ignore: [Levels.HTTP], // ignored log levels array
  settings: {
    showDateTime: false // show dateTime string
  }
}

You may also set the minimum log level and ignored log levels with setters.

qlog.level = Levels.DEBUG;

qlog.ignore = [Levels.HTTP];
