I’m very curious to know more about how you achieved fast calculation and scroll detection. Could you maybe give some details about how you optimised that? I’m right now working on a project and I have used the new IntersectionObserver API (polyfilled) and it has worked very well in terms of performance. Did you maybe use the same approach?
+ huge kudos for proving that investing into PWA’s makes sense from an engineering as well as a business standpoint. It’s way easier for devs in smaller companies to justify taking the time to improve perf :)
