I'm making the Front part of an application in React and can't find information on how to implement the application's loading behavior. I take 2 bots as an example (Wallet, Durger King), they have their own placeholders. I can only implement a white screen (screen from a third-party bot "@Nespat_bot").
durger-king_bot - image (good)
nespat_bot - image (bad)
I tried adding inside index.js, but it was rendered after the application was initialized. It seems to me that this placeholder needs to be added somewhere outside the react application, but I don’t know where
Did you try lazy loading with Suspense components?
