nodejs_is_url_ok.js

    let options = {
        host: 'eposthub.de',
        //port: 80,  optional
        //path: '/'  optional
    }

    const http = require('http');

    let isOk = await new Promise(resolve => {
        http.request({method:'HEAD', host:options.host, port:options.port, path: options.path}, r =>
            resolve(r.statusCode >= 200 && r.statusCode < 400)
        ).on('error', resolve).end();
    });
