Although WASM is brilliant, I don't think its right to use it to recreate the whole UI drawn to canvas. You loose all accessibility integration with the OS either locking out users or making your life much harder reimplementing it. WASM is perfect for graphics and backend processing, see Figma it uses WASM for drawing the canvas but the rest of the ui is native web with all the accessibility tools that come with the browser/os.

My life was made much harder when Flash and Silverlight like tooling was taken away.

The craziness of faking UIs with paragraph tags massaged via CSS and JavaScript into a drop down menu.

Now they are back, even Google Docs is moving into it.

Yew doesn't use the canvas, it uses the DOM iirc.

He talks about Yew [0], and you link to flutter?

Sorry.

I stand corrected on that one.
