parcel-plugin-workbox - service worker generator for Parcel
On every rebuild, this [Parcel][https://parceljs.org] plugin will generate a [Workbox][https://developers.google.com/web/tools/workbox/]-based service worker - sw.js
- and insert a registration code into the index.html
entry file.
The service worker will pre-cache all the files generated by Parcel.
