    Hi chinedufn, this looks very interesting. I am at the same stage as you re. "I REALLY want to use this for everything ...".

    I see you're using wasm_bindgen quite a bit, but from a cursory look at the code; I can't figure out something:

    I can see how you're using wasm in the front-end, but could you please elaborate a bit more about in the backend? I presume that your backend is Rust based?

    I spent last weekend porting some code from NodeJS to a wasm module. I got it sort of working on Node, but haven't tried it on the browser yet (ran out of weekend).

    I'm quite optimistic about wasm [and Rust with wasm_bindgen]. I'd been thinking of writing a native add-on for Node, but the idea that I can use wasm instead is exciting.

    Can someone ELI5(+) what an isomorphic virtual dom is?

    How does this compare to the Yew framework?

    The use of the html macro is incredibly nice, no need for a special "JSX" language, it’s all builting thanks to macros. I’m working on the same thing for python (using pyxl/mixt/lys and brython) and you just proved that there’s interrest in that !

    Heads up, there's something already called Percy in the JS space. https://percy.io

    Has Facebook picked up on this yet? Good thing the Web is a Web of documents.

    can you write an app in just once file and mark what can run in the client and what must only run on the server?

    Another good tool if you want to write front end in a great general purpose language is scalajs. It allows you to reuse the dame Scala code for backend and front end.
