typescript rest arguments 전달 방법

console.log()는 아래와 같이 선언되어 있다.

interface Console {

    Console: typeof NodeJS.Console;

    assert(value: any, message?: string, ...optionalParams: any[]): void;

    dir(obj: any, options?: {showHidden?: boolean, depth?: number, colors?: boolean}): void;

    error(message?: any, ...optionalParams: any[]): void;

    info(message?: any, ...optionalParams: any[]): void;

    log(message?: any, ...optionalParams: any[]): void;

    time(label: string): void;

    timeEnd(label: string): void;

    trace(message?: any, ...optionalParams: any[]): void;

    warn(message?: any, ...optionalParams: any[]): void;

}

이걸 랩핑 하려면

function log(level: Level, message?: any, ...optionalParams: any[]) {

    if (config.log.level <= level) {

        console.log(message, ...optionalParams);

    }

}

export function debug(message?: any, ...optionalParams: any[]) {

    log(Level.Debug, message, ...optionalParams);

}

위와 같이 전달하면 잘 동작 한다.
