Source Maps not working with Webpack
In bundle.js you will see original transpiled webpack bundle – this is normal behaviour. Open webpack:// and you will see your project files.

You should not use externals: [nodeExternals()], in web app. According to https://github.com/liady/webpack-node-externals it is only for backend. Since you use nodeExternals in web app you get CommonJS modules, that expects built in node require function. So just remove it to fix error.
Nullish coalescing operator is natively supported starting from eslint>=7.5.0. The easiest is set ES2020 in your package.json: { “eslintConfig”: { “parserOptions”: { “ecmaVersion”: 2020 } } }
You can export like this: import App from ‘./App’; import Home from ‘./Home’; import PageWrapper from ‘./PageWrapper’; export { App, Home, PageWrapper } Then, you can import like this wherever you need it: import { App, PageWrapper } from ‘./index’ //or similar filename … You can read more about import and export here. I also …
Try adding exclude: /node_modules/ after loader: ‘babel-loader’. I had the same problem when trying to run the runtime transformer without excluding node_modules. I am not aware of the underlying problem, though.
Babel has a separate preset for React, see http://babeljs.io/docs/plugins/preset-react/ To install this, run the following command (this adds it to your node modules and your devDependencies in package.json) npm install –save-dev babel-preset-react
Set up different environments in your .babelrc { “env”: { “dev”: { “presets”: [“es2015”], “plugins”:[“x”] }, “test”: { “presets”: [“es2015”] } } } And then run babel after you have set your BABEL_ENV BABEL_ENV=test <commandhere> or BABEL_ENV=dev <commandhere> If you don’t set BABEL_ENV, babel will use the NODE_ENV value. If you don’t set either BABEL_ENV …
You have 2 unclosed <div> tags in your render() and a semicolon that probably doesn’t belong. I’d get rid of those (e.g. close them, delete the semicolon in <div>; if it doesn’t belong) and try it again.
What could I be missing? Babel assigns default exports to the default property. So if you use require to import ES6 modules, you need to access the default property: const Button = require(‘./Components/Button.js’).default;
I’d like to add another reason why this error might pop up: I did the following: import mapActions from ‘vuex’ instead of: import { mapActions } from ‘vuex’ The former was importing the entire vuex export, which is an object. Adding object destructuring fixed the problem.
