Answer 1

You can use this:

const json2csv = require('json2csv').parse;

const csv = json2csv(json, fields);
console.log(csv);

Answer 2

Have you referred the documentation https://github.com/zemirco/json2csv#json2csv-parser-synchronous-api about how to use the api ?

Answer 3

const json2csv = require('json2csv');

const csv = await json2csv.parse(json, fields);
console.log(csv);

Answer 4

jsonocsv is an event emitter so you have to use on some specific events for example

json2csv
  .on('header', header => console.log(header))
  .on('line', line => console.log(line))
  .on('error', err => console.log(err));

These threee are some of the emitter which trigger your function to run I think you will find what you want in the doucmentation examples and options section of the json2csv documentation
