Defer Web Install Banner

Question

According to developers.google.com it is possible to defer the Web App Install banner, however I have only been able to cancel it completely. window.addEventListener('beforeinstallprompt', function(e) { console.log('beforeinstallprompt Event fired'); e.preventDefault(); return false; }); One use case is to defer the prompt until later in the page lifecycle, for example just after a user has performed an action, or hit the bottom of the page (something to indicate that they are engaging with your site). How is it possible to defer the web-app banner?

Try to check this documentation, if it can help you. Here is the complete code that use in deferring the Prompt. var deferredPrompt; window.addEventListener('beforeinstallprompt', function(e) { console.log('beforeinstallprompt Event fired'); e.preventDefault(); // Stash the event so it can be triggered later. deferredPrompt = e; return false; }); btnSave.addEventListener('click', function() { if(deferredPrompt !== undefined) { // The user has had a postive interaction with our app and Chrome // has tried to prompt previously, so let's show the prompt. deferredPrompt.prompt(); // Follow what the user has done with the prompt. deferredPrompt.userChoice.then(function(choiceResult) { console.log(choiceResult.outcome); if(choiceResult.outcome == 'dismissed') { console.log('User cancelled home screen install'); } else { console.log('User added to home screen'); } // We no longer need the prompt. Clear it up. deferredPrompt = null; }); } }); For more information, check also this link.
