Thank you! I am the guy on the video. We will be open sourcing Gea Stack next month, and in the meantime I am showcasing the examples we've built so far. The underlying framework, Gea, is already available for the web on https://geajs.com.

Oh how interesting, a new take on reactive UI, curious to see how it works, I see there's a Vite plugin that compiles JSX. Looking forward to learning more, and how this relates to the TypeScript to C++ compiler. Hmm, sounds like the GUI on WaveShare would be written in JSX, like React Native does for mobile UI.
