$ npm install webpack-cli -g
The official CLI of webpack
webpack CLI provides a flexible set of commands for developers to increase speed when setting up a custom webpack project. As of webpack v4, webpack is not expecting a configuration file, but often developers want to create a more custom webpack configuration based on their use-cases and needs. webpack CLI addresses these needs by providing a set of tools to improve the setup of custom webpack configuration.
When you have followed the Getting Started guide of webpack then webpack CLI is already installed!
Otherwise
npm install --save-dev webpack-cli
or
yarn add webpack-cli --dev
