A webpack block that adds happypack support to your webpack config.

This package is based on the PR by @fenos on the official webpack-blocks repository.

$ npm install --save-dev webpack-blocks-happypack

const { createConfig, babel, css, extractText } = require('webpack-blocks')
const happypack = require('webpack-blocks-happypack')

const config = createConfig([
  css.modules(),
  happypack([
    // these will be happypack'd
    extractText(),
    babel(),
  ]),
])

const config = createConfig([
  happypack([
    babel(),
  ], {
    // default options
    loaders: ['babel-loader', 'css-loader'], // allowed loaders
    cache: !process.env.DISABLE_HAPPY_CACHE,
    cacheContext: {
      env: process.env.NODE_ENV,
      refresh: process.env.REFRESH_HAPPY_CACHE ? Math.random() : 0,
      // ... add or override happypack cacheContext options
    },
    // ... add or override happypack options
  }),
])

$ DISABLE_HAPPY=true webpack # turns happypack off and run webpack
$ DISABLE_HAPPY_CACHE=true webpack # turns happypack cache off and run webpack
$ REFRESH_HAPPY_CACHE=true webpack # refreshes happypack cache and run webpack
