Using PapaParse to Parse a Local File?

Question

Currently, I'm trying to parse a "local file" this,

import Papa from 'papaparse';

Papa.parse( '../raw/M49/en.csv', {
  header: true,
  delimiter: ',',
  complete: (res) => console.log("COMPLETE", res),
  error: err => console.log("ERROR", err)
} );

When I run that code, this is all I get back,

{ data: [],
  errors: [],
  meta:
   { delimiter: ',',
     linebreak: '\n',
     aborted: false,
     truncated: false,
     cursor: 17,
     fields: [ '../raw/M49/en.csv' ] }

Papa Parse has three modes,

Parse String (Obviously don't want it)
Parse Remote File (what you want)
Parse Local File (misnamed, should be Parse Web API File Object -- specific to a "File Object" from the Web API)

These are both in browser-parlance where a "LOCAL FILE" is represented by a File Object. The option that accepts a path, is to Parse a Remote File, this requires setting the unintuitive option,

download: true

Even worse, running this will return,

ReferenceError: XMLHttpRequest is not defined
