webpack resolve error with packaged css file referencing an image

I'm working on a Vue component library built via VueCLI (and using Storybook Js, Bulma, and Buefy) and I am having issues consuming the CSS downstream. Specifically when I import the CSS file from my package, I am getting Webpack errors with referenced images.
For example, in my upstream src scss files I have a file called "notice-badge.scss" and am referencing background images like so:
.notice-badge img {
background-image: url('#/assets/img/warning-dark.svg');
}
and my src directory structure looks like:
my-app/
|--src/
|--assets/
|--scss/
|-- notice-badge.scss
|--img/
|--warning-dark.svg
|--fonts/
|--vue-components/
and I build the packages with this command which produces no errors.
vue-cli-service build --target lib --name my-ui-components ./src/index.ts
This outputs my JS, a CSS file, and 2 directories (img and fonts) into my "dist" directory. The images listed in my errors are infact inthere.
So over in another Vue cli app (and later Nuxt) I will be importing the CSS file and Vue components but I am getting a "can't resolve" error on that warning-dark.svg file:
Can't resolve /img/warning-dark.a45b259b.svg in /Users/myname/sites/my-app/ui-components/dist. My package also contains font awesome font files too (a business decision to include this all up stream)
So how can I get my downstream Vue CLI app to resolve the images and fonts referenced inside my node_modules dir?

You have (at least) 3 options:
Inline the images/fonts as data URLs.
Use a relative path in the output and require apps that install your package to move the image directory to the same path as the built CSS file.
Don't ship built CSS, but instead source SCSS files. That way file loading/moving can be handled with WebPack configuration in the app that uses it (using file_loader. You can include example configuration in your package to make this easier.
If you're writing a Vue component library, it probably makes most sense to use method 3. However from your description it seems like this may not be an option (the business decision you mention). Method 2 might be viable but I didn't try it nor seen someone else suggest it.
Inline
This method probably is easiest and has best performance. If your other SVGs are similar to the examples, it seems like they should all be relatively small files. There's few reasons for a component library to ship big images, so this might be sufficient for your use case.
If you're using WebPack 5, you can inline assets using "Asset Modules".
module: {
rules: [
{
test: /\.svg/,
type: 'asset/inline'
}
]
}
If you tried this, you may have run into the following problem.
Since Sass implementations don't provide url rewriting, all linked
assets must be relative to the output.
If you pass the generated CSS on to the css-loader, all urls must be
relative to the entry-file (e.g. main.scss).
If you're just generating CSS without passing it to the css-loader, it must be relative to your web root.
You can try replacing url('#/assets/img/warning-dark.svg') with url('../img/warning-dark.svg') (or whatever the path relative to the entrypoint is). Does it now properly inline them?

How to use static files with Custom Web Component

I have created a web component, uploaded it to npm, and imported it into another project.
I use webpack to bundle all of the code used within the web component, which creates a bundle file (in my case index.js).
This is the structure of my dist folder:
/dist
/static
/images
/fonts
index.js
Everything works, except loading images or fonts (static files). How can this issue be overcome? I have just added the static files to a public github repo at the moment, and load them from there. But I do not think this is the right way to do it.
I guess if the images are not that large, they can be converted into base64 and just bundled with the rest of the code?
Any thoughts
Found a similar question Paths in Web Components are Relative to Root.
The webcomponent specification defines that URLs are always relative
to the main document. This, of course, breaks web component
encapsulation, as you rightly concluded. In other words, the
specification is buggy, and lots of people are complaining about it.

JS, WebPack, Not Dynamically Loading Images Using Phaser3 Beyond Preload Function For IO Game

My attempts at making an IO game is failing, as I can't dynamically load images after I have packed the game using WebPack (a hypothesis). When I lazy load any assets whether it be cross origin or local, it doesn't seem to load and render.
in index.js I have this in phaser's create():
this.load.image('arc_red', 'https://art.pixilart.com/187aec08b8014f7.gif');//testing with this
this.load.once('complete', ()=>{console.log('image loaded!')}, this);
this.load.start();
when I use the preload, it does work. But dynamically it does not. I've been searching for nearly a day straight without any luck.
question:
Is my assumption correct? And if it is, what is a way I can dynamically load images after WebPack has packed the files?

I'm no webpack expert (and depending on the webpack version), but if you are not using a webpack.config, the default behavior is that there should be:
webpack bundle files are placed into the ./dist folder. So to answer your question, any file that is not in this folder is not bundled with webpack
Except if they are "inlined" in the main.js, I think images are not be inlined automatically/without plugin, or atleast in the version I used to use.
dev-server offers an extra folder, where "static" files can be placed, it is ./public(https://webpack.js.org/configuration/dev-server/)
So all files that are served from the dev-server must be in on of those folders.
I would place the images/assets into that ./public folder, and than they should be visible.
Info: I tripped over this once, files placed in ./public folder are accessed, as if they would be in the ./dist folder.

Cannot create Vue application http-server - Error: css and js files 404 Not found

I want to dockerize my vue app, but when I run it in a docker container nothing is loaded in the browser.
Since I run CMD["http-server", "dist"] in my Dockerfile, I decided to test it out locally to troubleshoot the issue.
Running:
npm run serve
Works fine and I get:
Then I run
npm run build
I believe this is due to having a posters folder with 50,000+ jpeg images in the assets directory which I dynamically display in the app as follows:
<div v-for="movie in this.recommendations" :key="movie" class="movie-card col-md-2">
<img v-if="movie['poster']=='True'" :src="getImgUrl(movie['movieId'])" v-bind:alt="pic">
And the getImgUrl function is:
getImgUrl(imgName) {
var images = require.context('../assets/posters', false, /\.jpg$/)
return images('./' + imgName + ".jpg")
}
vue/cli suggests
webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.
For more info visit https://webpack.js.org/guides/code-splitting/
but I'm not sure how to implement either one of these or
if hosting the images on a public google drive and importing them from there would solve the issue?
Pretty new to vue so any help would be much appreciated!

By using the assets folder and using require you are bundling all of your images into your code, by encoding them as base64. So when it is compiled it is creating GIANT chunks. Because the images are compiled into the source.
What you should do is move your images from assets to the public directory. Then load the images via HTTP. This means that your code and images remain separate. When the page loads, the browser requests the images separately from your code, and loads them into the file.
For example
<img v-if="movie['poster']=='True'" :src="getImgUrl(movie['movieId'])" v-bind:alt="pic">
getImgUrl(imgName) {
return `/posters/${imgName}.jpg`
}
Thus your directory structure would become
-public
-|--posters
-|--|--Poster1.jpg
-|--|--Poster2.jpg
-|--|--Poster3.jpg
-|--|--Poster4.jpg
etc
The public directory overly simplified acts as a webserver. Anything that is in it can be accessed directly. For example, if you were to move your images over, to the public directory, with the directory structure above, and access localhost:8080/posters/Poster1.jpg, it would load just the image, without even needing a Vue router.
For a better, in-depth description of the public folder, and the role it serves check out the docs.

Using webpack and publicPath for static resources

The following question was rewritten, because I have now a working solution, but no answer to the question above.
The repository that shows different scenarios how to use resources packed with webpack is named example-webpack-dynamic-resources. It contains 3 modules:
inline: a solution, but not useful in my context (many resource files)
file: a solution by using the plugin webpack-require-from
public-path: no solution yet, shows how I would like to use __webpack?public_path__.
I think I have read any resource about webpack and publicPath and __webpack_public_path__, but I don't get it to work. I try to dynamically change the path to static resources, but it fails.
Here is my context:
I build a Javascript library that will be used on web pages (HTML, CSS, Javascript).
It provides a lot (>100) static resources to small image files, combined > 500 KB. Only a fraction of it will be used by the user looking at the web site.
Therefore I would like to pack the CSS into the bundle, but keep the image resources in a directory located on the server somewhere. The default path to it will be /img.
As long as I use the same structure (which means, images only under ROOT/img/**, everything is ok.
But the users of the library should be able to configure the path to the image resources on their will.
You will find all relevant files in my example repository example-webpack-dynamic-resources in the module public-path-resources.
webpack.js: Use file-loader for images, which are referenced in CSS files. CSS will be inlined by style-loader and css-loader.
src/public-path.js: Define the global variable with a default (no environment variable).
src/index.js: require first public-path, then the logic.
examples/exam1-root/index.html: Tries to use the assets in the sub directory lib, sets the value therefore to __webpack_public_path__ = '/lib/. Not working.
examples/exam2-different-dirs/index.html: Moves the library to a different dir (not relevant), but uses the originally defined directory pgnv-assets for the assets. Working.
examples/exam3-non-standard-dirs/index.html: Try to use instead my-assets as directory for the assets. Not working.
How could the __webpack_public_path__ defined at runtime in the index.html file?
