How can I make a "Install app function?"

I want to make an “install app” thing that looks like the screenshot below:

I know that I might need a manifest.json file, but is that it? What else do I have to do to make it work?

Hey @code-alt,

This feature is available only for Progressive Web Apps. See a starter PWA here: It includes a manifest.json, a service worker and a script file. More complex PWAs use Workbox, which is used to cache assets and make better PWAs.
