How to use node modules for a (Firefox) web extension with ParcelJS

[odebroqueville]

I created a web extension with the following folder structure:

It namely contains an options.html file which includes the following line of code:
<script type="module" src="./scripts/options.js"></script>

Then, options.js includes the following import statement:
import Sortable from 'sortablejs';

where sortablejs is a node module contained within the node_modules folder. Yet, when I type npm run build, the resulting dist folder contains no trace of the sortablejs node module:

In addition, the fonts inside the fonts folder are being duplicated with a hash.

My package.json file namely contains the following:

    "scripts": {
        "test": "eslint .",
        "lint": "eslint .",
        "start": "parcel watch manifest.json --host localhost --config @parcel/config-webextension",
        "build": "parcel build manifest.json --config @parcel/config-webextension"
    },

Finally, the files bookmarks.html, history.html and defaultSearchEngines.json are all also missing in the dist folder. Do these files need to be placed in the src folder?

1. What do I need to do to have sortable.min.js added to the dist folder?
2. What do I need to do to avoid having the fonts duplicated?
3. Is there an option that will prevent hashes being added to file names?
4. Is it possible not to have the .json files (namely manifest.json) minified?
5. Can ParcelJS be used to create the required output (dist) for a Chrome extension or do I have to make the changes manually?
