A Create react app that has been set up as a PWA
Clone the repo and run npm install or yarn install.
This is basically a Create React App that contains only three components out of the box:
1. Shell component
2. Header component
3. Loader component
This contains a manifest.json file, as well as icons in all sizes required for Lighthouse to give 100% score in the PWA section. Before deploying make sure you register the service worker on index.js.
