failed to load wasm application

I'm trying to host a website, and I use a .wasm file with .js scripts created by the wasm-pack tool.
I tested the project locally with npm and node.js and everything worked fine.
But Then I hosted it on a raspberry (apache2), and when I try to access it, I get in the following error:
Failed to load module script: The server responded with a non-JavaScript MIME type of "application/wasm". Strict MIME type checking is enforced for module scripts per HTML spec.
details
There are multiple files, but here is the idea:
my index.html loads the module bootstrap.js
// bootstrap.js content
import("./index.js").catch(e => console.error("Error importing `index.js`:", e));
my main code is in the index.js, which calls test_wasm_bg.js
And finally, test_wasm_bg.js loads the wasm file with this line:
// test_wasm_bg.js first line
import * as wasm from './test_wasm_bg.wasm';
Where is the problem?
What is the right way to load a web assembly file?

I finally found what is the right way to load a wasm application in a wasm-bindgen project!
In fact, everything was on this page
When you compile the project without wanting to run it with a bundler, you have to run wasm-pack build with a --target flag.
wasm-pack build --release --target web.
This creates a .js file (pkg/test_wasm.js in my example) with everything you need to load the wasm-application.
And then this is how you use the functions created by wasm-bindgen (index.js):
import init from './pkg/test_wasm.js';
import {ex_function, ex_Struct ...} from '../pkg/test_wasm.js';
function run {
// use the function ex_function1 here
}
init().then(run)
You include your index.js in your HTML file
<script type="module" src="./index.js"></script>
And then it work's !
Edit:
Now that's I understand the javascript ecosystem a bit more, I cab try to explain what I understand:
There are many ways to do imports in js, here is a list :
https://dev.to/iggredible/what-the-heck-are-cjs-amd-umd-and-esm-ikm
You don't need to know much about that, except that the default target of wasm-pack is a node style ecmascript module. This import will work in node.js, but not directly in the browser. So in node, you can import a function from a wasm file directly, like so:
import {ex_function} from "./test.wasm"
But these styles of import don't work in the browser right now. Maybe it will be possible in the future
But for now, your browser only knows about js modules. So if you try to import a .wasm file directly in the browser, it will throw a mime type error because it doesn't know how to deal with webassembly files.
The tool you use to go from ecmascipt modules (with a lot of nmp packages for example) to a single js file is called a web-bundler (webpack, rollup, snowpack ...). If you work on a big project with npm, you probably need one. Otherwise, the "--target web" will say to wasm-bindgen to instantiate the wasm module the right way (look at the pkg/test_wasm.js)

SyntaxError: Unexpected token '*'. import call expects exactly one argument [Posenet]

I'm trying to run posenet off a python http server and encounter a syntax error in the camera.js file at this line.
import * as posenet from '#tensorflow-models/posenet';
The code is cloned from the GitHub repository: https://github.com/tensorflow/tfjs-models/tree/master/posenet/demos
I'm very new to javascript so any help will be much appreciated.

The import declartion itself is fine. I haven't seen that specific error, but it reads like the kind of error you'd get in an environment that supports dynamic import (import()) and you try to use a module script as though it were a non-module script. In a non-module script, import isn't a declaration, so the JavaScript engine (or whatever's parsing the script) assumes you're trying to use dynamic import (since unlike import declarations, you can use dynamic import in non-module scripts).
You haven't said how you're running this script, but be sure you're running it as a module, not as a non-module script:
In a browser, either import it from another module or run it via <script type="module" src="./your-file-name.js"></script>
In Node.js, be sure package.json has "type": "module" (or use .mjs instead of .js on your filename). Details here.
If using a bundler, be sure the bundler knows that the script where that declaration appears is a module script (how you do that will vary by bundler).

Unexpected token '<' Error (npx create-react-app)

I've setup a new react app using npx create-react-app my-app.
In the index.html file I want to import a javascript file in the head like so
<script src="/src/.../file.js"></script>
However, I keep getting Unexpected token '<' error. I can't do an import as it creates loads of errors and I want to be able to use some functionality in these scripts across the site.
Any ideas how to reference this file? Previously in other projects we use webpack but this config doesn't seem available in this project.

If your js files are located in the /public/ folder then you can import it like this:
<script src="%PUBLIC_URL%/.../file.js"></script>
If it is located in /src/ folder, you can simply import it to your index.js file, and it will be available across your React application. Remember that order of imports matters here.
import './.../file.js';

in a reactjs application made with create-react-app, how do I import js module in a file outside of project directory structure?

I am working with the following directory structure:
/sharedlib
/apps/create-react-reactjs-app-A
/apps/create-react-reactjs-app-B
create-react-reactjs-app-A and create-react-reactjs-app-B are both applications made with create-react-app. I would like both applications to be able to use javascript modules defined in files in a third folder, sharedlib. How do I configure my applications to allow them to import modules like this? When I attempt to do so, I get the following exception:
SyntaxError: export declarations may only appear at top level of a module

Importing Node Modules With JavaScript

I apologize for the simple question, but I'm pretty new to web development and JavaScript.
I want to import a package I've installed using npm, specifically shopify-buy following the guide here: https://shopify.github.io/js-buy-sdk/
The package is in my node_modules folder and I'm trying to import it into a JavaScript document using import Client from 'shopify-buy';
When I try to load everything up in Chrome, I get an error on the import line
Uncaught SyntaxError: Unexpected identifier
The Firefox error is a bit different: import declarations may only appear at top level
What am I doing wrong?
Edit:
The import line is the first line in my JavaScript file. And my HTML file is properly linked to the JS file (I think).
shopify.js
// Functions for SHOPIFY
import Client from 'shopify-buy';
const client = Client.buildClient({
domain: 'xxxxx.myshopify.com',
storefrontAccessToken: 'xxxxx'
});
index.html
<script src="javascript/shopify.js"></script>

If you want to use npm modules via the syntax, like import sth from "something" for browsers, you'd need to set up a module bundler and ES6 compiler, such as Webpack and Babel. You'd need to google them and find tutorials for setting up them accordingly.
An easy way to use the SDK seems to be using the CDN, since it's already been built for browsers to understand. Something like:
index.html
<script src="http://sdks.shopifycdn.com/js-buy-sdk/v1/latest/index.umd.min.js"></script>
<script src="javascript/shopify.js"></script>
shopify.js
const client = ShopifyBuy.buildClient({
domain: 'your-shop-name.myshopify.com',
storefrontAccessToken: 'your-storefront-access-token'
});
console.log(client);

JavaScript Modules can only be run in module-mode scripts. Change your HTML to the following:
<script type="module" src="javascript/shopify.js"></script>
