I remember now about #r2u. That looks good indeed.

Is there a way to make it work with `renv` or another package management system? (I looked at a couple Github issues and I think the answer is no, but maybe it's changed)

@veerle.hypebright.nl I know you dug into Shiny internals, maybe you have an idea why it behaves like that?

I'm discovering some obscure stuff.

Why does the same computation take 6x more computation time in an #RShiny app compared to an #Rstats script?

If I remove the `observe()` wrap it takes only 3 seconds. So it definitely comes from being observed.

For example, is there any way to measure how much time an app takes to fully load initially?

I have a few ideas in mind but not sure what's the best way to do that

What exactly do you mean by "mastering"?

Does knowing how to use the apply family functions qualify?
Knowing purrr?
Being able to contribute and mentor over purrr internals?
Being an expert in functional paradigms such as recursion and whatelse?

-> For my question, I’d say knowing some basics

That’s what I did in the end, just took a note for later and ship it in an "unoptimized" way
