Logging Weekly about winston-daily-rotate-file

[mattberther]

This should be resolved with #66.

What I want to do is to repeat log files weekly not for weekday.So for example from Monday to next Monday. Should I just pass

datePattern: 'Mon',

Also I want to add the week pattern to the filename.This is what I was trying

const tsFormat = () => (new Date()).toLocaleTimeString();

const logger = new (winston.Logger)({
transports: [
new (require('winston-daily-rotate-file'))({
filename:${logDir}/-results.log,
timestamp: tsFormat,
datePattern: 'ddd',
prepend: true
})
]
});
