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

Agreed, seems a useless metric at this point.
Yeah I just don't really get it!
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?
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.
Nice that's kind of what I thought INP was, but it's definitely a little confusing 💯
I'm loving those 🐍 case numbers though! 🙌🏻
This is to combat blocking server response times!
Which part? INP doesn't factor in server response times if your request to the server is asynchronous...
th-cam.com/users/shortswXw1Zg9g4k4?si=t7IdXAsyRklkd_UN okay so my bad, background tasks related to performance give the L.
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
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
great video
