Write a file into specific folder in node js?

Would like to write data into specific folder using writefile in node js.

I have seen couple of questions in stackoverflow regarding this but none of them worked for me .

For example :

fs.writeFile('./niktoResults/result.txt', 'This is my text', function (err) {    if (err) throw err;    console.log('Results Received');});

This throws an error "NO SUCH FILE OR DIRECTORY"

Is there any alternative for writing data into specific folder node js ???
