How to use the node-libcurl.Curl.option function in node-libcurl

this.setProxy = (host, proxyType) => {
        this.curl.setOpt(Curl.option.PROXY, host);

        // SOCKS5 default
        if (typeof proxyType === 'undefined') {
            this.curl.setOpt(Curl.option.PROXYTYPE, Curl.proxy.SOCKS5_HOSTNAME);
        } else {
            this.curl.setOpt(Curl.option.PROXYTYPE, proxyType);
        }

        return this;
    };
