How To Install Webpack
Simple tutorial on how to setup webpack v2.
The latest webpack release is: To install the latest release or a specific version, run one of the following commands: npm install--save-dev webpack npm install--save-dev webpack@ If you're using webpack v4 or later, you'll need to install the CLI. Npm install--save-dev webpack-cli Installing locally is what we recommend for most projects. Initialize npm to create a package.json file, then install webpack locally. $ mkdir bootstrap-webpack && cd bootstrap-webpack $ npm init -y $ npm install webpack --save-dev Create the following directory structure for your project, separating the “source” code /src from our bundled “distribution” code /dist.
- NPM Install Webpack Plugin Speed up development by automatically installing & saving dependencies with Webpack. It sucks to Ctrl-C your build script & server just to install a dependency you didn't know you needed until now.
- If you use webpack for a serious task, and you'd like us to invest more time on it, please donate. This project increases your income/productivity too. It makes development and applications faster and it reduces the required bandwidth.

Setup & Installation
Step 1 - Create folder
First let's create a directory called webpack-2-demo and initialize npm:
Step 2 - Install webpack
or do it via Yarn
Step 3 - Write webpack config
Create a webpack.config.js in root of our directory and let's write some configuration.
Now lets add lodash to dependencies in package.json by.
And let's write some code in src/app.js
Step 4 - Run the webpack
To run webpack in development mode.

or run webpack in production mode.
pis for production which uglifies and minifies files.

Step 5 - Setup webpack development server
Webpack has its own development server. Lets setup that in webpack.config.js by adding the following.
And add the script for bundle.js in src/index.html.
Step 6 - Run development server
Run development server.
Open http://localhost:8080/ in your browser.
Ultimate zip cracker license key. Thats all basic webpack config is done. But what about SASS, IMAGES, ES6 loaders ? How to setup that ? Lets see.
Loaders
Lets set up ES6 + Babel using a webpack loader.
Step 1 - Install babel loader,core & ES6 preset.
After installation, We have to add config to webpack.config.js file.
Step 2 - ES6 Loader
In order to check babel loader, we will change app.js to ES6 syntax.
Run the development server and check the console.
Step 3 - SASS & CSS Loader
Install SASS & CSS Loader
SASS & CSS loader config for webpack is below.
After loaders, final steps are setting up sourcemaps and env for webpack.
Step 7 - Setup Dev & Prod Environment
In package.json file, lets add scripts to run our dev server and build with env.
NODE_ENV=production is environment set for build. Using process.env.NODE_ENV, we can check the env in webpack.
Step 8 - Sourcemap for Dev & Prod
Now we know when we are running production build or development. Lets use it to setup the sourcemap accordingly.

Final step contains all the config for webpack from above.
Thats all. Thanks for reading my repo.

I have installed webpack both globally (first) and for a certain project also (PC, windows 10). Seems that the project dir contains all the folders that it needed:
But when I run the command in the project dir:
It reveals an error:
Then I check installed package for node:
It says that's OK (?):
Nevertheless, the error remains.Pls, tell me, can it be fixed and how?!
Just in case, here is the content of the node_modules/webpack/package.json file:

When you install a module globally npm install -g webpack (as is required by webpack), it actually becomes available on your command line. So you just need to run:
As for the error which you were getting when running:
that's because when you run node webpack you're actually (supposedly) passing the file webpack.js (or webpack/index.js) to node, hence the 'Cannot find module' error.
