Question

if (process.env.NOW_URL || process.env.HEROKU_URL) {
    const http = require('http');
    const port = process.env.PORT || 8080;

    http.createServer(bot.middleware()).listen(port, () => bot.setWebhook(process.env.NOW_URL || process.env.HEROKU_URL));
} else {
    logger.debug('Could not find the now.sh/Heroku environment variables. Trying to use the local ngrok server.');
    return ngrok.getPublicUrl().then(publicUrl => {
        const http = require('http');
        const port = process.env.PORT || 8080;

        http.createServer(bot.middleware()).listen(port, () => bot.setWebhook(publicUrl));

    }).catch(error => {
        console.log('Can not connect to ngrok server. Is it running?');
        console.error(error);
        process.exit(1);
    });
}
