How to use the @expo/bunyan.DEBUG function in @expo/bunyan

...(process.env.DEBUG && process.env.NODE_ENV !== 'production'
      ? [
          {
            type: 'raw',
            stream: new ConsoleRawStream(),
            closeOnExit: false,
            level: 'debug',
          },
        ]
      : []),
  ],
});

logger.notifications = logger.child({ type: 'notifications' });
logger.global = logger.child({ type: 'global' });
logger.DEBUG = bunyan.DEBUG;
logger.INFO = bunyan.INFO;
logger.WARN = bunyan.WARN;
logger.ERROR = bunyan.ERROR;

export default logger;

stream: new ConsoleRawStream(),
            closeOnExit: false,
            level: 'debug',
          },
        ]
      : [],

export type LogStream = bunyan.Stream;
