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

import winston from 'winston';
export declare class Logger {
    private logger;
    constructor(options?: winston.LoggerOptions);
    enableInfo(): void;
    enableInfoFile(options?: winston.transports.FileTransportOptions): void;
    enableErrorFile(options?: winston.transports.FileTransportOptions): void;
    enableDebug(): void;
    info(message: string, args?: {
        [key: string]: any;
    }): void;
    error(message: string, args?: {
        [key: string]: any;
    }): void;
    debug(message: string, args?: {
        [key: string]: any;
    }): void;
    debugFunctionCall(functionName: string, functionArguments: any, args?: any): void;
}
