Wordpress installing supabase and imports

I am trying to connect with my Supabase API and following the docs
Supabase DOCS
But everytime I write down:
import { createClient } from '#supabase/supabase-js'
I get an error "import declarations may only appear at top level of a module"
So is it even possible to use the npm install #supabase/supabase-js in my child theme and then uploading it?
Or what else is going wrong here?
I tried typing type="module" when trying it with the CDN link but still the same error.

Uncaught SyntaxError: Cannot use import statement outside a module Vue 3 PWA Workbox

I am trying to convert my vue js app into a PWA. Following the workbox documentation in the following link:
https://developers.google.com/web/tools/workbox/modules/workbox-strategies
I have to import some modules
import { registerRoute } from 'workbox-routing';
import { StaleWhileRevalidate } from 'workbox-strategies';
import { Queue } from 'workbox-background-sync';
After running npm run build, vue js automatically generates the following line of code which is at the top of service-worker.js file followed by the imports mentioned above:
importScripts("/precache-manifest.f6666fe9d8f679ee90db8a98ef900aa4.js", "https://storage.googleapis.com/workbox-cdn/releases/4.3.1/workbox-sw.js");
My app is fully functional without any errors, if I remove the imports, the service worker is registered successfully. When i add the imports I am getting this error:
Uncaught SyntaxError: Cannot use import statement outside a module
Error during service worker registration: TypeError: Failed to register a ServiceWorker for scope ('http://127.0.0.1:8887/') with script ('http://127.0.0.1:8887/service-worker.js'): ServiceWorker script evaluation failed
From my research I have learned that the scripts need to be bundled using webpack or a similar service.
https://developers.google.com/web/tools/workbox/guides/using-bundlers
However since I am using the CDN to importScripts, according to my understanding it should automatically bundle as stated in the following website:
https://developers.google.com/web/tools/workbox/modules/workbox-sw

It's an either-or thing: if you have full control over your build a bundling process, then following the "Using bundlers with Workbox" guide and using the ES module import {...} from '...' syntax, but not using workbox-sw, would work.
If you don't have full control over your build process (and it sounds like you don't), then you can use workbox-sw to load the rest of Workbox. Since you already have the importScripts('/path/to/workbox-sw.js') in your service worker, using statements like workbox.routing.registerRoute() or workbox.strategies.registerRoute() in your service worker, and not putting in any import {...} from '...' statements, should just work.

import module without nodejs - vanillaJS

I'm refreshing my old and low knowledge on VanillaJS using the latest best practices i found.
I recently did a tutorial on NodeJS doing API REST with ExpressJs and one with Socket IO.
Now I want to practice a little before going to REACTJS.
So I started a little project
I do one without NodeJs - just JS into HTML view - using Objects.
I want to use modules from Npm. I want to try Fakerjs but when i want to import it i have a 403.
The path is correct, no error.
So i'm wondering if it's possible without Nodejs to import modules when doing VanillaJs?
Am i doing it wrong ?
The structure of the project is :
js/
main.js
class/
node_modules/
index.html
Main.js:
'use strict'
//Importation of modules
import faker from '../node_modules/faker'
//Importation of Class Folder
import { Crypto } from "./class/crypto.class.js";
console.log(faker);
faker.locale = 'en_US';
I have this error in console:
GET http://crypto-market-js.local:8282/node_modules/faker/ net::ERR_ABORTED 403 (Forbidden)
If i write : import faker from 'faker' (like with node js but it's a require instead) i have this : Uncaught TypeError: Failed to resolve module specifier "faker". Relative references must start with either "/", "./", or "../".
If you could give me a hand on that plz :)

Trying to import with require is not supported without NodeJS, because require is a node-specific function. When trying to import modules into Vanilla JS, my recommendation is to first link to ths script with the <script> html tag, and then add another script with import faker from 'faker'
Hope that clarifies your issue.

Error trying to import 'systemjs' to use import dynamically

I am trying to use SystemJS to import a module that lives on an external server. Having problems just getting started with importing systemjs so that I can use it in code.
import System from 'systemjs';
OR
import * as System from 'systemjs';
// System not found, error on line above trying to import systemjs as module.
System.import('https://test.com/modules/somemodule.js').then(module => {
// got the module
});
Neither work. This is all assuming its possible to use System.import(...) in code to import a module. Reading through the docs not really sure how to import systemjs.
Error:
Module not found: Error: Can't resolve 'systemjs'

JavaScript error when importing a package

getting the following error when importing netscape.javascript
importClass(netscape.javascript)
org.mozilla.javascript.EcmaError: ReferenceError: "netscape" is not defined.
Trying to use javascript within applet to get access to cookies.
Using the following as an example to import required package
http://www.java2s.com/Code/Java/JDK-6/UsingJavaObjectsinJavaScript.htm
http://docs.oracle.com/javase/tutorial/deployment/applet/invokingJavaScriptFromApplet.html

Found out by trial and error.
It seems we need to prefix with Packages
importPackage(Packages.netscape.javascript);
