I noticed when doing the section I had an error and server crash “Invalid transport, must be an object with a log method”
so I check documentation and there is only one reference to log method which says something about and needing to call createLogger()
HOWEVER!! after much testing and comparison between i realized winston.transport’s File is a constructor function and needs to bee newed up before and becomes a function where you pass a transport object so this fixed the issue.
working solution
winston.add(new winston.transports.File({ filename: “logfile.log”}))
mosh’s implementation now deprecated
winston.add(winston.transports.File, { filename: “logfile.log”})
