How can I import Papaparse into Web Extension JavaScript code?

Question

How can I include Papaparse so I can use it in Web Extension Javascript code?

I know this might be obvious to any experienced JavaScript programmer, but I am not very experienced with JavaScript. Other programming languages, yes, but not JavaScript.

I have been working on a Web Extension. It gets bundled into an xpi file to be installed into my browser. And now I want to add the ability to parse CSV input.

I just cannot figure out how to make it so I can use papaparse.min.js in my JavaScript. The Readme on GitHub makes it look so easy:

import Papa from 'papaparse';

Papa.parse(file, config);

But I think that requires an npm setup that my code cannot rely on, no? My code is not using node.js at all.

I have downloaded papaparse.min.js directly into my project directories. And I have tried using an import like my code is using for several other modules that it requires:

import { Papa } from '../modules/papaparse.min.js';

And of course I get an error message like this:

Uncaught SyntaxError: The requested module '<project directory>/modules/papaparse.min.js' doesn't provide an export named: 'Papa'

With all the other imports my code needs -- mostly from npm modules I have installed and whose source files I have then copied into my project directory -- I have been able to find the exports my code needs in order to use the modules, but not with Papaparse. I can't see any export statements in the code.

I have tried installing the entire npm module. I copied all its files into my project, then I have tried these as well:

import * as Papa from '../modules/papaparse/papaparse.min.js';
import * as Papa from '../modules/papaparse/papaparse.js';

papaparse.min.js gives: Uncaught TypeError: e is undefined

papaparse.js gives: Uncaught TypeError: root is undefined

I am stuck.

Thank you for any help you might give me.

I was able to import it by sticking it in a <script> tag. For example:

<head>
  <script src="papaparse.min.js"></script>
  <script>
    console.log(Papa)
  </script>
</head>
