A logger and log middleware. Why logan? Because it sounds like morgan

import 'express';
import { Logger } from '../../logger';
declare global {
    namespace Express {
        interface Request {
            id: string;
            logger: Logger;
            addLogData: (data: {
                [key: string]: any;
            }) => void;
            addLogError: (error: any) => void;
        }
    }
}
