Installation

$ npm install webpack -g

The webpack command is now available globally.

Pure CLI

webpack <entry> <output>

entry

Pass a file or a request string. You can pass multiple entries (every entry is loaded on startup).

If you pass a pair in the form <name>=<request> you can create an additional entry point.

It will be mapped to the configuration option entry.

output

Pass a path to a file.

It will be mapped to the configuration options output.path and output.filename.

configuration options

Many configuration options are mapped from CLI options. I. e. --debug maps to debug: true, or --output-library-target to output.libraryTarget.

You see a list of all options, if you don't pass any option.

plugins

Some plugins are mapped to CLI options. I. e. --define <string>=<string> maps to the DefinePlugin.

You see a list of all options, if you don't pass any option.
