How to import and use bpmn file in vue component with aid of raw-loader

I'm new to bpmn-js and try to import and use a .bpmn file in a vue.js component (BPMNViewer.vue). My research only brought up to use the raw-loader. So I'm kind of at a loss here.
<script>
import demo from './examples/demo.bpmn'
...
export default {
data() {
return {
xmlData: demo,
};
}
}
This results in the following Error:
error in ./src/views/BPMNViewer.vue?vue&type=script&lang=js&
Module not found: Error: Can't resolve './examples/demo.bpmn' in '/bpmn-test/src/views'
ERROR in ./src/views/BPMNViewer.vue?vue&type=script&lang=js& (./node_modules/#vue/vue-loader-v15/lib/index.js??vue-loader-options!./src/views/BPMNViewer.vue?vue&type=script&lang=js&) 12:0-39

webpack compiled with 1 error
I try to integrate the raw-loader in my vue.config.js:
const { defineConfig } = require('#vue/cli-service')
module.exports = defineConfig({
transpileDependencies: true,
chainWebpack: config => {
config.module
.rule("bpmn")
.test(/\.bpmn$/)
.use("raw-loader")
.loader("raw-loader")
.end();
}

Seems like I miss something here. Please let me know if I need to provide more information.

This looks like nothing Bpmn-js specific. Can you first ensure that the raw XML is indeed available in your xmlData object?
Your webpack may not be configured to use the raw-loader or not to use it for for the .bpmn extension. An inline solution would be
ìmport demo from 'raw-loader!./examples/demo.bpmn'
(if you don't have the raw-loader yet:
npm install raw-loader --save-dev)

Support for the experimental syntax 'jsx' isn't currently enabled error on imported module

I'm building an npm package that includes one react component as part of it. I originally developed the package as just a subfolder of the react app I was testing it on and it was all working. Now that I've extracted the code and turned it into it's own package, when I try to import it and build the react project it receives the error:
Support for the experimental syntax 'jsx' isn't currently enabled
...
Add #babel/plugin-transform-react-jsx (https://git.io/vb4yd) to the 'plugins' section of your Babel config to enable transformation.
When I run build on the extracted package itself it builds with no issues, it's only when I try and incorporate it into the other project that it has issues. I've tried many of the other solutions from other threads with no luck.

Published npm package does not apply styles

I'm currently working on creating an npm package. Which is basically a React component with added styles using SCSS. When I test it out, the class names are there, but no styles are being applied.
Here is the repo for the package. I use a separated webpack config for building the specific folder where the component is.
Here's the webpack configuration I'm using:
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const EsLintFormatter = require('eslint-formatter-pretty');
const path = require('path');
const pkg = require('../../package.json');
const { SRC_PATH, BUILD_PATH } = require('./constants');
const setStyleLoaders = require('./style-loaders');
const alias = require('./alias');
const packageName = pkg.name;
module.exports = ({ NODE_ENV }) => ({
mode: 'production',
entry: `${SRC_PATH}/components/Carousel/Carousel.js`,
output: {

This is the result when testing the published package:
Edit 1:
There are no errors on the Network and Console tab in devtools. I also can't find the file loaded, even though it's there in the package. It seems like the js file is not using it, but it should.
Edit 2:
Thanks for pointing me on the right direction!
I added import 'react-clear-carousel/build/index.css'; to include the CSS file from my package. I can see the file now (on devtools), but the styles are not being applied since css-loader is modularizing it and adding additional suffix and prefix (even though it already had them), thus having different class names that the ones my component has.
eg. My component is rendered as <div class="carousel_swimlane--kXSjh">, but the styles in the DOM are named as index_carousel_swimlane--kXSjh--2C.
I guess the question is now, how do I tell Webpack to pass this CSS as is? And if there's a way for me to deliver the CSS file without other people having to change their Webpack configuration.

Looking at your repo I see that you are importing your scss but attributing it's properties to classNames.
className should be the name of the class, and you can either attribute your imported styles to style or you can load your compiled css into the DOM using <link rel="stylesheet" type="text/css" href="styles.min.css">
The reason you're not seeing a stylesheet in the network tab is because you've simply forgotten to declare a stylesheet.

How to prevent webpack to fail build on eslint error?

i used the default vue-cli command to create a vue project.
When webpack is building, it fails, as shown in the image:
I am not using any special webpack configuration. What am i doing wrong?
My package.json:
{
"name": "myapp",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",

},

},

}

You can force ESLint to always emit just warnings instead of errors by webpack configuration. That will not stop your build as you expect. You need to set emitWarning option to true in your webpack.config.js file.
eg.
module.exports = {
module: {
rules: [
{
test: /\.vue$/,
exclude: /node_modules/,
loader: "eslint-loader",
options: {
emitWarning: true
}
}
]
}
};
You can read more in the documentation https://github.com/webpack-contrib/eslint-loader#errors-and-warning

i guess with the new eslint/webpack stuff, this is default behaviour.
So this is my workaround in my .lintrc.js file:
'no-console': process.env.NODE_ENV === 'production' ? 2 : 1

NoEmitOnErrorsPlugin is now automatically enabled in webpack 4, when mode is either unset, or set to production. So even ESLint warnings will fail the build. No matter what error settings are used for eslint-loader, except if emitWarning enabled.

Redux Web Extension - Uncaught TypeError: Invalid attempt to spread non-iterable instance

I am working on a React application that also uses the Redux dev tools extension. It is running on Node and used Webpack to compile. I recently upgraded my application to Webpack 4 from 2.
The application compiles fine through the use of the webpack command but when I try and run it in the browser I get the following error which kills the app:
Uncaught TypeError: Invalid attempt to spread non-iterable instance
The error is happening in my configureStore.js file where I am configuring the redux store. See below line 7 import { composeWithDevTools } from 'redux-devtools-extension'; is causing the issue.
configureStore.js
import { createStore, applyMiddleware } from 'redux';
import rootReducer from './rootReducers';
import reduxImmutableStoreInvariant from 'redux-immutable-state-invariant';
import thunk from 'redux-thunk';
import {routerMiddleware} from 'react-router-redux';
import createHistory from 'history/createBrowserHistory';
import { composeWithDevTools } from 'redux-devtools-extension';
const history = createHistory();
const middleware = routerMiddleware(history);
export default function configureStore(){
return createStore(
rootReducer,
composeWithDevTools(
applyMiddleware(reduxImmutableStoreInvariant(), thunk, ...middleware)
)
);
}
When I remove this extension my initial page loads. However, I want to keep this extension in the app. Any ideas or suggestions as to why this might be happening and how to keep this working? Below are additional files as reference points.

Or alternatively declare it directly
applyMiddleware(reduxImmutableStoreInvariant(), thunk, ...[middleware] )
EDIT : This is how i set up mine, for better readability
const middleware = [reduxImmutableStoreInvariant(), thunk, routerMiddleware(history)];
const store = createStore(reducers, initialState,
composeWithDevTools(applyMiddleware(...middleware)));
