javascript - Write to a CSV in Node.js

Question

I am struggling to find a way to write data to a CSV in Node.js.

There are several CSV plugins available however they only 'write' to stdout.

Ideally I want to write on a row-by-row basis using a loop.

You can use fs (https://nodejs.org/api/fs.html#fs_fs_writefile_file_data_options_callback):

var dataToWrite;
var fs = require('fs');

fs.writeFile('form-tracking/formList.csv', dataToWrite, 'utf8', function (err) {
  if (err) {
    console.log('Some error occured - file either not saved or corrupted file saved.');
  } else{
    console.log('It's saved!');
  }
});
