PWA: How to retrigger beforeinstallprompt?

Question

Our site uses PWA so that the visitor can choose to Add to Home Screen (A2HS). However, from Google Analytics data, the Dismiss rate is too high compared to Acceptance rate.

We plan to make the UX more intuitive and clearer to improve the acceptance rate. However, we also want to revive those visitors already dismissed the A2HS dialog.

How to do so? To the extend of my knowledge, we only can add beforeinstallprompt listener but there is no openinstallprompt method.

Answer 1

In Dev mode,

Try this in devtools(tried in chrome) console to trigger the event:

event = new Event('beforeinstallprompt')
window.dispatchEvent(event)

Caution: We won't be able to open the in-browser modal by calling prompt on the event.
