  });

If you want to capture some data at any specific place then

logger.customEvent('some_event_name', {foo: 'bar'}, 'info') // third argument is level which can be any of these [info, warn, error]

If you want capture logs of streaming data (i.e res.write('some data') then do as below)

router.use(logger.captureStreaming(), session) // session is express-session midleware
