Solution for winstonjs logging to multiple transport files simultaneously instead of one. Issue link: https://github.com/winstonjs/winston/issues/614. Inspired solution proposal link: https://github.com/winstonjs/winston/issues/614#issuecomment-405015322

	import { createLogger, format, transports } from "winston";

	const { combine, json, prettyPrint, timestamp } = format;
	const formatCombination = [json(), timestamp(), prettyPrint()];
	const levels = ["info", "warn", "error", "fatal"] as const;

	function getFilter(level: (typeof levels)[number]) {
	return format((log, _) => (log.level === level ? log : false));
	}
