Notes on PWAs and app manifests

bits i learned about web app manifests and PWA icons, what’s obsolete like gcm_sender_id and shortcut icon, plus useful links

• gcm_sender_id is no longer needed in Chrome 52+

• apple-touch-icon-precompose is no longer needed since iOS 7

• rel="shortcut icon" As per MDN The shortcut link type is often seen before icon, but this link type is non-conforming, ignored and web authors must not use it anymore.

Links
