I got a quick question. I want to save the value (string) of this statement:

process.stdout.write(d); 

in a variable. But all my attempts failed so how is it done?

res.on('data', (d) => {
    process.stdout.write(d);         
});

You can do it like this

var str = "";

res.on('data', (d) => {
   str+=d;
}).on('end',()=>{
   console.log(str);
});

Here we append the data d we get from stream, we append it to str variable & the print the str once the stream pletes reading
