Winston: Add a Logger instance to winston.loggers

[sinai-doron]

I am trying to to create multiple loggers by doing

winston.loggers.add('category1', {})

I thought to create new loggers by "new winston.Logger" and then adding them like this:

myNewLogger = new winston.Logger({transport: [...]})
winston.loggers.add('category1', myNewLogger)

but the Logger is changing the transports to an object instead on an array which causes an exception in
container.js line 52: options.transports = existing ? existing.slice() : [];

because an object does not have a slice method

thanks

The winston.loggers.add method expects options to be passed to a new Logger instance, not a Logger instance itself. e.g.: this will work

winston.loggers.add('category1', { transports: [/* Your transports etc */] })

Why does winston.loggers.add('category1', {level: "error"}) not work? It treats "level" as transport, but I will use the default transport of main logger.

@ChristophAtAdlos did you ever figure out why this was? Having the same issue.
