I have to work on an app where the user has to interact with the app fast ( its for an emergency)
Is there a way to implement a pair of buttons on a preloader screen / splash screen on a PWA ?
PS:- I am a beginner please excuse me if this is a dumb question
No, you cannot add buttons to the splash screen.
You can customize it by selecting a background color or icon (through the manifest.json file). The splash screen disappears as soon as the PWA is loaded.
If you are interested in learning more about PWAs, I wrote a series of articles about this topic.
