Offline PWA News Reader
Installable news app that caches articles for reading offline
1-2 weeks build
Overview
A progressive web app that pulls headlines from a public news API through a small proxy that keeps the API key off the client. A Workbox service worker caches the app shell and recent headlines, and articles saved to the reading list are stored in IndexedDB so they open with no connection. The app installs to the home screen and syncs the list when back online.
