Add more priorities

[astoilkov]

Currently, I have added only two priorities to the library — background and user-visible. I feel this won't be enough. However, I can't imagine all the use cases the library will be used in. This is why I am starting a discussion here, so together, we can find the right priorities.

You can read more about priorities here and here.

Wild idea, but would is be possible to do something like extend the delay adaptively? RIC does this but it's often too fast.

I've used algorithms that are able to calculate current CPU pressure. I mainly do this so I can block third party tags by monkey patching document.createElement. Then based of CPU pressure I can suspend the unblock rates till CPU isn't under so much stress.

Another one that might be interesting to consider is suspending when the user interacts with the page, scrolling or clicking around - tho some of this might be covered by by requestAnimationFrame

I like the idea. Maybe I can use it as a fallback when navigator.scheduling.isInputPending() isn't available. Do you have examples of a code that tries to do that? I will be interested in learning from it.

This is covered by navigator.scheduling.isInputPending() when available. When not available the library is a lot more conservative to do work without giving back control to userland.

I started experimenting with this. We will see how it goes.

Is some part of that open-source? I would love to take inspiration.

My current idea is to use fps tracking: https://github.com/astoilkov/main-thread-scheduling/blob/980ad69b477779ff882eac16ac7cd2a60331e16c/playground/utils/fps.ts. If fps is low, I will spend less time in scheduled tasks. I will add an option to the yield methods where you can control the wiggle room in ms. What do you think @ScriptedAlchemy?
