Building Web Apps
summary
Focuses on concrete APIs and outcomes: explains service workers as a caching proxy that enables offline, push and background sync; shows the web app manifest fields that control icons, splash and display modes; demonstrates Samsung Internet’s ambient badging (shipped on S8/DeX) and cites Samsung as third‑most used mobile browser in some markets (10–20%). Covers Chrome install logic (third visit in two weeks), Lighthouse scoring (out of 104) and a Node push NPM helper for cross‑browser push payloads. Safari lacks full support.
