you drop a WASM bundle on the screen and it parses it and visualizes the size of each section/function therein.
It also traces function calls, such that when you hover over one function, it also shows you what functions are called from it.
here's an example of what you get when you drop applookfat's own bundle into itself (kinky!)
i would argue that one of the greatest caveats of WASM is the killing blow it deals to the "open web."
hopefully this project "opens" your WASM for you a bit; although you do need debug symbols for it to be useful.
it's all written in C and rendered with WebGL because your WASM bundle is fat as fuck and any overhead is too much overhead.
actually, i could be leveraging C and WASM far more efficiently; there are still WASM bundles for which this app stutters and chokes. progress to be made, iterations to be had and so forth.
