winston.rejections is missing

[ab-pm]

The docs claim:

If you want to use this feature with the default logger, simply call .rejections.handle() with a transport instance.

//
// You can add a separate rejection logger by passing it to `.rejections.handle`
//
winston.rejections.handle(
  new winston.transports.File({ filename: 'path/to/rejections.log' })
);

This probably was copied verbatim from the respective section on exception handling, but does not work. The winston object does not expose a .rejections property that's forwarded to defaultLogger.rejections, like it does for exceptions:

winston/lib/winston.js

Lines 128 to 137 in 80d3439

	/**
	* Define getter for `exceptions` which replaces `handleExceptions` and
	* `unhandleExceptions`.
	* @type {Object}
	*/
	Object.defineProperty(winston, 'exceptions', {
	get() {
	return defaultLogger.exceptions;
	}
	});

Also, a related issue, the LoggerOptions interface does not define a 'rejectionHandlers' field, though the Readme shows an example of passing a 'rejectionHandlers' option to 'createLogger'.

interface LoggerOptions { levels?: Config.AbstractConfigSetLevels; silent?: boolean; format?: logform.Format; level?: string; exitOnError?: Function | boolean; defaultMeta?: any; transports?: Transport[] | Transport; handleExceptions?: boolean; exceptionHandlers?: any; }

`
// Enable rejection handling when you create your logger.

const logger = createLogger({
transports: [
new transports.File({ filename: 'combined.log' })
],
rejectionHandlers: [
new transports.File({ filename: 'rejections.log' })
]
});
`
