I'm more saying bundlephobia.com is wrong in that it doesn't appear to be including .wasm files at all.
If you just do an npm install of canvaskit-wasm you'll find a 6.4M canvaskit.wasm file. That'd have to be some insane gzip magic to bring that down to 50Kb.
If I gzip the entire canvaskit module (including the font files) I'm getting a size of 3.4M. If I just gzip the .wasm file I get a size of 2.4M.

I'm not saying you are wrong, but if the NPM package needed more stuff it would be in the package.json, no?
