I found the truth behind how INP is calculated. It was very misleading!

you re right. but you know that browser receives SIGNAL from monitor to update approximely each 16ms (60fps), so that means the user input and your event handler shoudnt block NEXT PAINT, thats idea behind INP. With your asynchronous call, you can implement an visual feedback before api call easily

@user-cx1de8xy8d Месяц назад

And for your question about how to block main thread, it s so easy. Remember then handlers (or code after await) are microtasks, and queue a lot of microtasks could block main thread, because they re prioritized. If you traverse an collection of 1000 records and casually in record #400 your browser needs to run render steps, the time of processing from #400 to #1000 will be a delay for NEXT PAINT even if are just 10ms

Nice that's kind of what I thought INP was, but it's definitely a little confusing 💯 I'm loving those 🐍 case numbers though! 🙌🏻

So this means any asynchronous call we make is not considered to effect INP. I'm wondering how do i even recognise what's main thread and how it's being blocked in a application?

@JamesQQuick 3 месяца назад

Honestly, most things would be async which is why I kinda struggle with this metric. I had a hard time coming up with reasonable examples of what would block the main thread.

@@JamesQQuick example is definitely helpful. I'm currently working on performance improvement as well so that's insightful to know.
