What does webpack mean by XX hidden modules

Webpack hides modules coming from folders like [“node_modules”, “bower_components”, “jam”, “components”] in your console output by default. This helps you to focus on your modules instead on your dependencies.

You can display them by using the –display-modules argument.

$ webpack --display-modules

Issue – configuration.resolve has an unknown property ‘root’.

In webpack.config.js I had below under resolve…

  resolve: {
    root: __dirname,

Final SOLUTION – https://stackoverflow.com/questions/43107233/configuration-resolve-has-an-unknown-property-root

resolve.root is Webpack 1 configuration and doesn’t exist for Webpack 2.

For Webpack 2 you can use resolve.modules:

resolve: {
    modules: [__dirname, 'node_modules'],

Issue – “webpack: command not found” – Suddenly getting this, from the same directory from where it was working just fine last night

First followed this.


“use the scripts property of your package.json to use webpack from this directory which will be exported.” So in package.json included the following in the script:

"scripts": {
  "build": "webpack --config webpack.config.js"

then $ npm run build

But still was getting the same error.

Hence, from – https://stackoverflow.com/questions/32550089/webpack-command-not-found-after-npm-install-webpack-g

Install it globally

npm i -g webpack

And now SOLVED.

Issue – CLI for webpack must be installed. These are recommended choices ALSO WAS GETTING “Cannot find module ‘webpack-cli”

Just install webpack-cli globally with $ npm i -g webpack-cli

Issue – webpac -w command failed giving me the following node-saas error

Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 9.x

The source of the problems is most certainly, that I upgraded the node version in between.

Solution – https://stackoverflow.com/questions/37986800/node-sass-could-not-find-a-binding-for-your-current-environment

npm rebuild node-sass

Another solution would have been –

Just delete the node-sass folder and run npm install

Issue – < webpack > would throw error – Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema. – configuration.module has an unknown property ‘loaders’.


All I had to do was rename loaders to rules – in the webpack.config file
