Config file

webpack-parallel expects array, single config or a Promise of config/s.

const myConfigs = [...] // array of webpack configs

// optional - if you'd see named configs instead of seeing indexes
export const configNames = ['friendly-config-name-1', 'friendly-config-name-2'] 

export default new Promise(...)
  .then(...) // do some clean up, any shared operations before build or watch
  .then(()) => myConfigs)

How to use it

It is used in conjunction with @hungry/webpack-parts - composable, typesafe webpack config, however it is not necessary.

Selling points

• compatible with webpack watch
• compatible with webpack-dev-server and hmr
• reliable error handling
• exposed separate command for yargs if you've got already your custom command line tree
• full report activity - sorted by worker id report from stdin and stderr
• can connect any worker - there is an utility class provided for communication and wrapper to run any config based on babel
• full control over pipes and rendering phase - if you want to help me extend it

Motivation

There is couple of implementation of parallel building for webpack, however I wanted to provide something dev oriented with clear error reporting when there is spawned many of concurrent builds.
