A2hs.js
📲 A useful modern JavaScript solution that helps your website users to add (install) a progressive web application (PWA) to the Home Screen of their mobile iOS devices.

The Why?
As you probably know, iOS Safari doesn't have a built-in pop-up window with a suggestion to install a progressive web app on an iPhone/iPad (like Google Chrome). The a2hs.js project easily solves this problem!
Also, it's lightweight, production-ready, zero-configuration, has no dependencies and perfectly works with all of popular JavaScript frontend frameworks.
Install
npm install --save a2hs.js
Usage
/**
* Import a2hs.js
*/
import AddToHomeScreen from "a2hs.js";
/**
* Simple (with default config) init
*/
AddToHomeScreen();
/**
* Advanced (with your config) init
*/
AddToHomeScreen({
brandName: "Demo",
fontFamily: "Tahoma, sans-serif",
backgroundColor: "red",
color: "white",
// ... see full list of config options below
});
