PWACompat: the Web App Manifest for all browsers
Use the PWACompat library to bring your Web App Manifest to all browsers. By simply dropping in the library, many of the link and meta meta tags required to support older browsers for icons, home screen behavior, theming etc, will be added automatically- no more steps required!
Using the web app manifest to specify a site wide theme color
Set a theme-color in the manifest and have it available to all pages on your site when launched from the home screen.
