Issue with integrating cortex-js/compute machine in react application

I am trying to use compute machine provided by the cortexjs. https://cortexjs.io/compute-engine
I saved this dependency using
npm i #cortex-js/compute-engine
After I ran npm start, I am getting this error:
ERROR in ./node_modules/#cortex-js/compute-engine/dist/compute-engine.min.js 2:1360
Module parse failed: Unexpected token (2:1360)
You may need an appropriate loader to handle this file type.
Following is my webpack file:
var webpack = require('webpack');
const HtmlWebPackPlugin = require("html-webpack-plugin");
var path = require('path');
module.exports = {
// output: {
// path: path.resolve(__dirname, 'dist'),
// filename: 'main.js',
// publicPath: '/'
// },
mode : 'production',
devServer: {
historyApiFallback: true,
},
devtool: "source-map",
module: {
rules: [
{
test: /\.(png|jpg|woff|woff2|gif)$/i,
use: [
{
loader: 'url-loader',
options: {
limit: 8192
}
}
]
},
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
{
test: /\.html$/,
use: [
{
loader: "html-loader"
}
]
},
{
test: /\.css$/,
loader: 'style-loader'
},
{
test: /\.css$/,
loader: 'css-loader',
options: {
import: true,
},
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: "./src/index.html",
filename: "./index.html"
})
]
};
Please can someone suggest which loader should I add to webpack.config file to make this work.

Cannot load image webpack (4.41.0)

I am trying to load a jpg image file using Webpack, but I keep getting the following error: Uncaught Error: Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js): ModuleParseError: Module parse failed: Unexpected character '�' (1:0)
I'm using file-loader, so I'm not sure what's wrong...
This is my webpack.config.js file:
module.exports = {
context: __dirname,
entry: {
frontend: ['./src/index.js', './src/sass/style.scss'],
customizer: './src/customizer.js'
},
output: {
path: path.resolve(__dirname, 'public'),
filename: '[name]-bundle.js'
},
mode: 'development',
devtool: 'cheap-eval-source-map',
module: {
rules: [
{
test: /\.(jpe?g|JPG|png|gif)\$/,
use: [
{
loader: 'file-loader',
options: {
publicPath: 'public/images',
name: '[name].[ext]'
}
}
]
}
My image is currently stored in a src/images directory. What could I be missing?
Thanks for your help!
Edit: Here is the CSS I'm using to pull in the image:
#header {
background: url('../images/header.JPG') no-repeat center center fixed;
background-size: cover;
}
Edit: Here is my entire webpack.config.js file:
const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const BrowserSyncPlugin = require('browser-sync-webpack-plugin');
const StyleLintPlugin = require('stylelint-webpack-plugin');
module.exports = {
context: __dirname,
entry: {
frontend: ['./src/index.js', './src/sass/style.scss'],
customizer: './src/customizer.js'

}
]
},

new StyleLintPlugin(),
new MiniCssExtractPlugin({
filename: '[name].css'
}),
new BrowserSyncPlugin({
files: '**/*.php',
proxy: 'http://mysite.test/'
})
],
optimization: {
minimizer: [new UglifyJsPlugin(), new OptimizeCssAssetsPlugin()]
}
};```

test: /\.(JPG|gif|svg|gif|png)(\?v=[0-9]\.[0-9]\.[0-9])?$/,
include: SRC,
use: [{
loader: 'file-loader'
}]
.
.
.

First try to replace your sass regex test like this :
test: /\.(sass|scss)$/
if it didn't work try replacing your whole rule like this :
{
test: /\.(sass|scss)$/,
use: [
MiniCssExtractPlugin.loader,
{
loader: 'css-loader',
},
{
loader: 'sass-loader',
}
]
}
also remove {filename: '[name].css'} from MiniCssExtractPlugin
with the two tries I mentioned keep it simple like that :
plugins:[
...
new MiniCssExtractPlugin(),
...

I have error '] Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema"

When I try to use command npm start, I get error
"] Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema."
Code: https://next.plnkr.co/edit/hEHTiPYQXQ7POWIH?open=lib%2Fscript.js&deferRun=1

I found your problem webpack use rules config not loader config so change your code into this
const HtmlWebpackPlugin = require('html-webpack-plugin');
const path = require("path");
module.exports = {
entry: 'src/app/app.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'index_bundle.js'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.html$/,
use: 'raw-loader'
},
{
test: /\.scss$/,
use: [
{
loader: 'style-loader'
},
{
loader: 'css-loader'
},
{
loader: 'sass-loader',
}
]
},
{
test: /\.css$/,
use: [
{
loader: 'style-loader'
},
{
loader: 'css-loader'
}
]
},
]
},
plugins: [
new HtmlWebpackPlugin({
template: 'index.html',
inject: 'body',
hash: true
}),
],
devtool: "#inline-source-map"
}
Update: move your index.html file into same level of webpack.config.js
I dont see in the document they allow user to change into different path
Please let me know if you still have a problem

Extract specific CSS files to a file with Webpack

What I'm trying to achieve is a Webpack configuration where CSS is handled by the final JS export, but, some specific files are exported to an external file (to optimize critical CSS loading).
So, the idea is: if the file name start with _critical-, put it in a file.
So, here is my webpack.config.js for the moment:
const path = require('path');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: './src/entry.js',
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js'
},
module: {
rules: [
{
loader: 'babel-loader',
test: /\.js$/,
exclude: /node_modules/
},
{
use: [
'style-loader',
'css-loader',
'sass-loader'
],
test: /\.s?css$/,
},
{
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [
'css-loader',
'sass-loader'
]
}),
test: /\A_critical-.*\.s?css$/,
},
{
test: /\.(png|jp(e*)g|svg)$/,
use: [{
loader: 'url-loader',
options: {
limit: 10000,
name: 'images/[hash]-[name].[ext]'
}
}]
}
]
},
plugins: [
new ExtractTextPlugin("styles.css"),
],
devtool: 'cheap-module-eval-source-map',
devServer: {
contentBase: path.join(__dirname, 'public'),
historyApiFallback: true
}
};
And, at some point, I have import './components/base/_critical-color.scss'; in my code.
When I run Webpack, no error. But no styles.css either.
What am I missing?

Webpack doesn't generate app.bundle.css

I have the following webpack file, however, when I run npm run dev the name.bundle.css file doesn't get generated: (no errors either)
const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
context: path.resolve(__dirname, './resources/'),
entry: {
app: './index.jsx'
},
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, './public/assets/'),
publicPath: '/assets/'
},
module: {
rules: [
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
use: [{
loader: 'css-loader'
}],
}),
},
{
test: /\.jsx|js$/,
exclude: [/node-modules/],
use: [
{
loader: "babel-loader",
options: { presets: ['react', 'es2015', 'stage-1'] }
}
]
},
{
test: /\.(sass|scss)$/,
use: ["style-loader", "css-loader", "sass-loader"]
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
use: ['file-loader?name=[name].[ext]']
},
{
test: /\.(eot|svg|ttf|woff|woff2)$/,
loader: 'file-loader?name=public/fonts/[name].[ext]'
}
]
},
resolve: {
modules: [
path.resolve(__dirname, './resources/'),
'node_modules'
]
},
plugins: [
new webpack.optimize.CommonsChunkPlugin({
name: 'common'
}),
new ExtractTextPlugin({
filename: '[name].bundle.css'
})
]
}
my CSS folder is:
CSS
- app.scss
COMPONENTS
comp1.scss
comp2.scss
it works this way "import styles from './css/app.scss';" but I would expect this to generate a app.bundle.css:
new ExtractTextPlugin({
filename: '[name].bundle.css'
})

You have 2 rules for both css and sass.
I think in your case you only need one:
test: /\.(sass|scss)$/,
use: ExtractTextPlugin.extract({
use: [{
loader: "css-loader"
}, {
loader: "sass-loader"
}],
fallback: "style-loader"
})
and like you said, you should import the scss files in the js files import './css/app.scss'
