Question

How can I rotate logs when using Winston to handle logging for node.js. That is, how can I create a new file for each day the app runs?

    var logger = new

According to the author of winston-filerotatedate it is a:

File transport for winston that allows the log files to be rotated depending on size and time.

The File transport accepts a filename via the 'filename' option and uses that file as the primary logging target. Should the file grow past 'maxsize' bytes then the current log file is renamed and a new primary log tile is created. The name of the renamed log file is formated as such 'basenameYYYYMMDD[a-z].bak'.

Available options are:

• level: Level of messages that this transport should log.
• silent: Boolean flag indicating whether to suppress output.
• timestamp: Boolean flag indicating if we should prepend output with timestamps (default true). If function is specified, its return value will be used instead of timestamps.
• filename: The filename of the logfile to write output to.
• dirname: The folder the logfile will be created in.
• maxsize: Max size in bytes of the logfile, if the size is exceeded then a new file is created.
• json: If true, messages will be logged as JSON (default true).
