Rollup plugin that builds a service worker as part of your rollup build by using workbox-build.

Shameless copy/paste of rollup-plugin-workbox by Benny Powers.

The only noteworthy change is the use of the writeBundle rollup hook instead of generateBundle, so that workbox-build can pick-up bundled assets after they have been written to disk.

Install as usual with:

npm i -D rollup-plugin-workbox-build

and use like this:

import workbox from 'rollup-plugin-workbox-build'

export default {
  input: /*...*/,
  output: /*...*/,
  plugins: [
    workbox({
      mode: 'generateSW', // or 'injectManifest'
      options: {
        swDest: 'service-worker.js',
        globDirectory: 'dist',
        // other workbox-build options depending on the mode
      },
    }
  ],
}

You can also pass your own callback for rendering workbox-build stats. It gets an object with the following properties:

• swDest {string} - the path to the generated service worker
• count {number} - the number of assets added for pre-caching
• size {number} - the resulting pre-cache size in bytes

• bring it on-par with the official workbox-webpack-plugin
