Package Exports

purgecss-webpack-plugin

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (purgecss-webpack-plugin) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

The options available in purgecss Configuration are also avaiable in the webpack plugin with the exception of css and content.

const PurgecssPlugin = require('purgecss-webpack-plugin')
const glob = require('glob')
const PATHS = {
  src: path.join(__dirname, 'src')
}

// In the webpack configuration
new PurgecssPlugin({
  paths: glob.sync(`${PATHS.src}/*`)
})

only

You can specify entrypoints to the purgecss-webpack-plugin with the option only:

new PurgecssPlugin({
  paths: glob.sync(`${PATHS.src}/*`),
  only: ['bundle', 'vendor']
})
