# webpack CLI
The official CLI of webpack
## About
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.
## How to install
When you have followed the [Getting Started](https://webpack.js.org/guides/getting-started/) guide of webpack then webpack CLI is already installed!
Otherwise
```bash
npm install --save-dev webpack-cli
```
or
```bash
yarn add webpack-cli --dev
```
## Supported arguments and commands
### Usage
All interactions with webpack-cli are of the form
```bash
npx webpack-cli [command] [options]
```
If no command is specified then `bundle` command is used by default
### Help Usage
You display basic commands and arguments -
```bash
npx webpack-cli --help
```
To display all supported commands and arguments -
```bash

```
