Slim down the WebAssembly build binary size #5403

Summary

The .wasm file is 22,80 MB which is quite hefty. I don't really need all the modules or even all the language features. Is there any way to slim it down?

Disabling the compiler feature (and freezing the standard lib) is the best you can do... that is unless you need the compiler at runtime in which case - not much you can do really
Doing that I've managed to slim down the binary to ~12MB from what I recall

(I went over this with @youknowone on discord some time ago; had the same "problem" I guess you could say. "no slim config ATM" - apart from the above - was the conlusion)

Oh and I should mention... there's nothing stopping you from freezing only some modules from the stdlib - if that didn't come out in the previous comment - the whole thing is very heavy

Perhaps there ought to be some information about this in the wiki.
