const options = {
    uri: "https://apost.dev/" // Validate URL
};

request.get(options, function (error, response, body) {
    if(!error && response.statusCode == 200){
        console.log('URI is alive!')
    }else{
        if(response.statusCode == 404)
            console.log('Page not found!')
        else
            console.log('Validate error: ' + response.statusCode);
