Implementing an installation of filepond

First of all, I’m new in web development, so this may be something really simple to answer (or at least I hope so).

I was trying to implement filepond in a project when I started running into problems.
Following a video guide I could use the library without any problems through CDNs, so I decided to try with npm installations by myself, but that’s when I started getting errors.

I can’t past the import part from the quick start guide (https://www.npmjs.com/package/filepond) and I would like someone to pin point what I’m doing wrong.

My Folder Structure:

/node_modules
   /...
/public
   /fileUpload.js
/views
   /index.html
/server.js

My code at the moment:

server.js (I’m running the code inside a node environment, express framework):

const express = require('express');
const path = require('path');

const app = express();

app.get('/', (req, res) => {
    res.sendFile(path.join(__dirname, './views/index.html'));
})

app.use(express.static('public'));

app.listen(5000);

fileUpload.js (exactly the same as the quick start guide):

import * as Filepond from 'filepond';

const pond = Filepond.create({
    multiple: true,
    name: 'filepond'
});

document.body.appendChild(pond.element);

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>FilePond</title>
</head>
<body>
    <input type="file" class="filepond">

    <script src="javascripts/fileUpload.js"></script>
</body>
</html>

Installations: npm i filepond

Error:
Running all the code above I get:

Uncaught SyntaxError: import declarations may only appear at top level of a module

And if I were to change the call of my .js file inside my html for the following one:

<script type="module" src="../public/javascripts/fileUpload.js"></script>

My error would change to:

Loading module from “http://localhost:5000/public/javascripts/fileUpload.js” was blocked because of a disallowed MIME type (“text/html”).
