Webpack dev server reloads but doesn't show Markup or CSS changes?

So i'm pretty new to Webpack, and I finally got the webpack-dev-server running. It recompiles and refreshes page on save, and it shows changes to my JS code. But it doesn't seem to work well with my SASS or HTML files?
On a fresh start, it will show a change if I make it, but if I undo that change, it doesn't update. Looking around other posts, I tried added the "--hot" flag, and adding "inline" to my devServer in webpack config. This got it working for a style change, but won't show deleted or undone changes.
This is my package.json...

I must have something wrong or out of place?
Any help or tips would be appreciated. Will provide additional info if needed.
Thanks in advance!

I found a solution by adding "watchContentBase" to my devServer.
devServer: {
contentBase: path.resolve(__dirname, 'dist'),
**watchContentBase: true,**
inline: true,
hot: true
}

ReactDOM.render not accepting JSX

I cannot get ReactDOM.render(...) to accept any JSX tag, however if I use React.createElement(...) it works.
This is my index.jsx file:
import React from "react";
import ReactDOM from "react-dom";
// THIS WORKS!
//var elem = React.createElement('h1',{},"Hello");
//ReactDOM.render(elem, document.getElementById("content"));
// THIS DOESN'T WORK!
ReactDOM.render(<h1>Hello World!</h1>, document.getElementById("content"));
In the index.html file there is a div with id="content" somewhere.
This is my package.json file:
{
"name": "static",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "webpack -p --progress --config webpack.config.js",
"dev-build": "webpack --progress -d --config webpack.config.js",
"watch": "webpack --progress -d --config webpack.config.js --watch"
},

"webpack": "^4.35.0",
"webpack-cli": "^3.3.5"
},
"presets": [
"#babel/preset-env",
"#babel/preset-react"
]
}
This is my webpack.config.js file:
const webpack = require('webpack');
const config = {
entry: __dirname + '/js/index.jsx',
output: {
path: __dirname + '/dist',
filename: 'bundle.js',
},
resolve: {
extensions: ['.js', '.jsx', '.css']
},
};
module.exports = config;
module: {
rules: [
{
test: /\.jsx?/,
exclude: /node_modules/,
use: 'babel-loader'
}
]
}
The error I am getting is:
ERROR in ./js/index.jsx 11:16
Module parse failed: Unexpected token (11:16)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

> ReactDOM.render(<h1>Hello World!</h1>, document.getElementById("content"));

==============================================
Solution:
1st of all the webpack.config.js was wrong (see accepted answer).
After, I had to install babel-loader with npm install -D babel-loader #babel/core #babel/preset-env webpack and then created .babelrc file at the same path of the other config. files, with the content:
{
"presets": ["#babel/preset-env", "#babel/preset-react"]
}

You are placing the rules in the wrong place.
the correct config is:
const webpack = require('webpack');
const config = {
entry: __dirname + '/js/index.jsx',
output: {
path: __dirname + '/dist',
filename: 'bundle.js',
},
resolve: {
extensions: ['.js', '.jsx', '.css']
},
module: {
rules: [
{
test: /\.jsx?/,
exclude: /node_modules/,
use: 'babel-loader'
}
]
}
};
module.exports = config;

webpack autobuild/auto serve application

i am using this webpack project template from here
to run it i use npm run serve .how can I add auto build/serve when files are changed. is it something to do with webpack or npm? .i am new to this javascript tooling & searching on google gives lots of options which is overloaded with information & configurations each different.
attaching the webpack config:
const path = require('path')
const webpack = require('webpack')
module.exports = env => {
return {
entry: {
main: './src/index.js'
},
output: {
filename: 'bundle.js',
path: path.join(__dirname, 'dist'),
publicPath: "/"
},
mode: env && env.production ? 'production' : 'development',
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['env']
}
}
},
{
test: [/\.vert$/, /\.frag$/],
use: 'raw-loader'
}
]
},
devServer
: {
contentBase: './dist'
},
plugins: [
new webpack.DefinePlugin({
'CANVAS_RENDERER': JSON.stringify(true),
'WEBGL_RENDERER': JSON.stringify(true)
})
]
}
}

Error: `output.path` needs to be an absolute path or `/` [duplicate]

This question already has answers here:
Getting "Error: `output.path` needs to be an absolute path or `/`"
(5 answers)
Closed 5 years ago.
I am a beginner in React,and at the moment I am trying to do the basic set up. So far I installed the basic modules from npm and the folder structure of my project is as shown below.
The package.json shows what I have installed as well as a small description of the project.
{
"name": "test",
"version": "1.0.0",
"description": "test",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server --hot"
},
"repository": {
"type": "git",

"react": "^15.4.2",
"react-dom": "^15.4.2",
"webpack": "^2.2.1",
"webpack-dev-server": "^2.4.1"
}
}
Anyway when I am typing npm start,I get this error.
Error: `output.path` needs to be an absolute path or `/`.
at Object.setFs (C:\Users\Theodosios\Desktop\reactApp\node_modules\webpack-d
ev-middleware\lib\Shared.js:88:11)
I believe this has to do with the webpack.config.js file.
var config = {
entry: './main.js',
output: {
path:'./',
filename: 'index.js',
},
devServer: {
inline: true,
port: 3000
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015', 'react']
}
}
]
}
}
module.exports = config;
How can this error be fixed?
Thanks,
Theo?

you need to define the output path relative to webpack config.
path: path.resolve(__dirname, './'),
publicPath: '/',
filename: 'bundle.js'

Webpack - Getting node modules Into Bundle and loading into html file

I am trying to use node_modules in the browser via WebPack. I've read the tutorial and beginning steps but am stuck.
I have used webpack to generate bundle.js with the webpack config below and upon going to my index.html in Chrome browser I get the error:
Uncaught ReferenceError: require is not defined
at Object.<anonymous> (bundle.js:205)
What additional steps do I have to do to get the browser to recongnize require?
index.html
<script src="bundle.js"></script>
<button onclick="EntryPoint.check()">Check</button>
index.js
const SpellChecker = require('spellchecker');
module.exports = {
check: function() {
alert(SpellChecker.isMisspelled('keng'));
}
};
package.json
{
"name": "browser-spelling",
"version": "1.0.0",
"description": "",

"dependencies": {
"node-loader": "^0.6.0",
"spellchecker": "^3.3.1",
"webpack": "^2.2.1"
}
}
webpack.config.js
module.exports = {
entry: './index.js',
target: 'node',
output: {
path: './',
filename: 'bundle.js',
libraryTarget: 'var',
library: 'EntryPoint'
},
module: {
loaders: [
{
test: /\.node$/,
loader: 'node-loader'
},
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader',
query: {
presets: ['es2015']
}
}
]
}
};

In your webpack.config.js you specified that you want to build this bundle for Node.js:
target: 'node',
And webpack decided to keep require calls, because Node.js supports them. If you want to run it in a browser, you should use target: 'web' instead.

In the new "webpack": "^5.75.0", Required has been changed to rules
webpack.config.js
const path = require("path");
var webpack = require("webpack");
module.exports = {
entry: "./index.js",
target: "node",
output: {
filename: "bundle.js",
path: path.resolve(__dirname, "dist"),
},
module: {
rules: [
{
test: /\.node$/,
use: "node-loader",
},
{
test: /\.js$/,
exclude: /node_modules/,
},
],
},
};
