Test typescript performance

[saiichihashimoto]

It would be really nice to test the performance of type checking, similar to jest's testTimeout (which I'm fairly confident only sets a timeout for the runtime of the test, not the compile time. I want to be able to confidently claim that it's fast in your IDE, but I don't know how to test that.

I know about typescript's performance tracing wiki but it would be nice to have an automated way to determine the speed of the typing portion, preferably of my tests.

Essentially, I'd like to eliminate the desire for something like ts-simplify and try to hone in performance issues (and eliminate performance regressions).

i can take a look at some of this (trying it on my system and sometimes the loading time for TS is frustrating)

I know it's been quite a while! @ickynavigator is this something you've been able to look at at all? I still don't really know how to test a typescript library's performance directly like this.

hey @saiichihashimoto, i mostly use sanity's generated types now but i'm more than happy to check this out! I think ArkType has a tool for testing type performances, it should be called @arktype/attest or so.
