Live deployment: https://so-pwa.firebaseapp.com/

This is a sample progressive web app which uses the Stack Exchange API to fetch the top questions and answers from Stack Overflow for a given tag.

Under the hood, it's powered by the following technologies:

• Service worker generation and Streams API logic via Workbox.
• Static and dynamic web hosting via Firebase Cloud Functions.
• "Universal" JavaScript via ES2015 source modules, bundled for the browser and Node by Rollup, with babel-preset-env ensuring compatibility with various runtimes.
• Shared server service worker routing logic using Express-style patterns and the regexparam library in the service worker.
