what is my wrong?
my OS is macOS highSierra version 10.13.3
node js version 10
react version 16.2
The rest/spread operators (...) are currently not in Babel by default, so you need at least the stage 3 preset (or the babel-plugin-transform-object-rest-spread by itself) for it to work properly:
.babelrc
{
"presets": [
"env",
"react",
"stage-3"
]

I am not able to package my Electron application with electron-forge.
It looks like that the culprits are the native modules such as 'sqlite3'.
When running the command npm run package, I get the following error:
Module not found: Error: Can't resolve './→' in 'C:\Users\pauco\mybeast\node_modules\node-pre-gyp\lib'
I tried:
npm rebuild
node_modules\.bin\electron-rebuild

you can use plugin to unpack native modules to be resolved
You can follow here:
https://www.electronforge.io/config/plugins/auto-unpack-natives
This plugin will automatically add all native modules in your node_modules folder to the asar.unpack config option in your packagerConfig. If you have any native modules as all you should probably use this to reduce loading times and disk consumption on your users' machines.
Usage:
You must add this plugin to your plugins array in your forge config
The complete config options are available at AutoUnpackNativesConfig.

Apparently it happened because you have two module properties in the webpack config object.
Given JS objects can only hold one value per key - one value would be lost. And in this particular case the latter was overwriting the former, so webpack ended up configured without typescript loader config at all.
Trying to replicate an example that someone develops through a video to configure the development environment to work with React Js, I have encountered a problem, which em is very confusing, considering that I did everything in the same way .
After executing the npm run dev command, as I have it configured in the ** package.json **, the following error appears:
npm run dev

Using chart.js 2.5.0 and webpack 2.2.1, the resulting bundle after minimization is 357K. I've tried various options to Uglify, but not much seems to matter.
Using these files:

import Chart from 'chart.js'
const root = document.querySelector('#root')
root.innerHTML = `<p>Hello webpack.</p>`

Turns out the issue is chart.js in npm depends on moment.js, which inludes about 250K of locales. The fix is to ignore these locale files:
var webpack = require("webpack");
module.exports = {
// ...
plugins: [
new webpack.ContextReplacementPlugin(/moment[\/\\]locale$/, /de|fr|hu/)
// new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/)
]
};
More info here:
How to prevent moment.js from loading locales with webpack?
As JOP explained, Chart.JS depends on moment.js package that has 250K with locales.
If you don't have dates in your chart data you can remove moment package completely from result bundle without replacing it with another package. Moment package just could be marked as an external dependency in webpack.
I.e. something like this, depending on you webpack configuration.
module.exports = {
...
externals: {
moment: 'moment',
},
}
Edit: The reason was that I was running webpack-dev-server, when running just webpack it worked.
I am using React and Webpack. The bundle.js is not generated. I found this question on SO that brought up the same issue, but I seem to have the required dependencies installed. Here is my webpack.config.js:
var webpack = require('webpack');
module.exports = {
entry: [
'webpack-dev-server/client?http://localhost:8080',
'webpack/hot/only-dev-server',
'./src/index.js'
],
module: {
loaders: [{
test: /\.js?$/,
exclude: /node_modules/,
loader: 'react-hot!babel'
}]
},
resolve: {
extensions: ['', '.js']
},
output: {
path: 'dist',
publicPath: '/',
filename: 'bundle.js'
},
devServer: {
contentBase: './dist',
hot: true
},
plugins: [
new webpack.HotModuleReplacementPlugin()
]
};

Any idea?

webpack: bundle is now VALID.
Theres probably something wrong with the output path .. can you try replacing the output path to ./dist
It is due to missing of some key-value pairs in scripts of package.json. Replace your scripts object with the following:
"scripts": {
"start": "npm run build",
"build": "webpack -p && webpack-dev-server"
},
"-p" means specially for production evnvironment of webpack.config.js. Then run this cmd: $ npm start
$ npm start will invoke npm run build cmd which in turn will invoke "webpack -p && webpack-dev-server"
