const alerts = require('google-alerts-api');
alerts.configure({
    mail: 'your_mail@gmail.com',
    password: '**********'
});

const { HOW_OFTEN, DELIVER_TO, HOW_MANY } = alerts;

alerts.sync(() => {
    const alertToCreate = {
        howOften: HOW_OFTEN.AT_MOST_ONCE_A_DAY,
        sources: [],
        lang: 'en',
        name: 'NodeJS AND "Chrome V8"',
        region: 'PL',
        howMany: HOW_MANY.BEST,
        deliverTo: DELIVER_TO.MAIL,
        deliverToData: ''
    };

    alerts.create(alertToCreate, (err, alert) => {
        console.log(err);
        console.log(alert);
    });
});
