PWA Install Polyfill
Propose invitation and installation helper for browsers which does not support them (Firefox, iOS...). Today, only Chrome and Edge browsers support the BeforeInstallPromptEvent. This lightweight library (<30ko) allows to get the same behaviour on some other browsers.
The PWA installation method depends on your browser. When a user accepts the installation invitation, a helper is showed to help him to install your application.
Currently supported language : en, fr
The invite banner is not triggered if the brower language is not supported. PR is welcome.
