New to webpack trying to understand how to make file structure, webpack.config.js and package.json work together, but not sure what is failing as the client.min.js(my outputted bunfdle file) is never regenerated upon NPM run dev
webpack.config.js:
var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');
var path = require('path');
module.exports = {
context: path.join(__dirname, "src"),
devtool: debug ? "inline-sourcemap" : null,
entry: "./js/client.js",
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/,
loader: 'babel-loader',
query: {
presets: ['react', 'es2015', 'stage-0'],
plugins: ['react-html-attrs', 'transform-class-properties', 'transform-decorators-legacy'],
}
}
]
},
output: {
path: __dirname+"/src/",
filename: "client.min.js"
},
plugins: debug ? [] : [
new webpack.optimize.DedupePlugin(),
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
],
};

NPM run dev result:
webpack-dev-server does not generate files. It serves all assets from memory.
If you want to generate files, run webpack.

I'm working on a React tutorial via Youtube and have matched his webpack.config and package.json files but I am getting a strange error when running webpack-dev-server

./src/js/client.js
import React from "react";
import ReactDOM from "react-dom";
import Bootstrap from 'bootstrap-without-jquery';
import Layout from "./pages/Layout";
const app = document.getElementById('app');
ReactDOM.render(<div>/Hello</div>, app);
The file structure matches the tutorial source code so I don't think that is an issue. However when I run npm run dev I get the following error
Webpack Error
If I comment out line 10 of client.js webpack compiles with no issue. (ReactDOM.render function)
You have Webpack 1 installed, which has all the loader configurations in config.module.loaders, but your config uses config.module.rules which was introduces in Webpack 2.
Installing Webpack 4 should resolve your issue.
npm install -D webpack#latest
I am aware that this is quite a common problem with Webpack, but I am a total newbie and the solutions I've found so far seem to be very specific to the single project. However, the scenario is the same: Webpack compiling the project correctly and then showing a blank page, without reporting any errors.
Here is my webpack.config.js (I made it following tutorials):
import path from 'path';
import HtmlWebpackPlugin from 'html-webpack-plugin';
export default () => ({

path.join(__dirname, 'src/index.jsx'),
],
output: {
path: path.join(__dirname, 'dist'),
filename: 'bundle.js',
},

new HtmlWebpackPlugin({

}),

Webpack version is the lastest and the project is written using React and ES5.
I am looking to use React application using MobX framework, into Electron.
I have success loading MobX with React, but when I try to wrap it with Electron, I have a console error message not allowed to load local resource

var path = require('path');
module.exports = {

};
Why does the electron saying that there he not allow to load local resource ? electron does not suppose to have access to local files? how can I solve this ?
Seems Like I accidentally route to the wrong path.
problem solved.

I am trying to get the browser to refresh every time I make changes to some of the components, but the changes don't take place.
Your issue is probably that you don't get to the loader with test test: /\.jsx?$/, since the first loader matches.
Can you try to use react-hot in the first module?
{
test: path.join(__dirname, 'src'),
loader: ['react-hot','babel-loader'],
query: {
cacheDirectory: 'babel_cache',
presets: debug ? ['react', 'es2015', 'react-hmre'] : ['react', 'es2015']
}
},
A more precise test for this loader would be better in the long run though.
I simply had to run this command:
"start-dev-hmr": "node_modules/.bin/webpack-dev-server --progress --inline --hot",
from

I'm pretty new to using React and Webpack so I'm likely doing something wrong, but when I build with the -p production flag my file size is considerably bigger (3.26MB vs 2.23MB) than when I build without.

I had the same problem and it got solved by removing the 'debug' property from webpack.conf.js. In stead I call webpack with the -d flag when I'm developing (and not when building the production bundle), as that adds the debug property automatically.
I see that debug is a conditional in your config, but at least it solved the problem for me.
