This is great, I think this is perfect use for web components and gives your customers trying to build a fully custom storefront a much better experience. I built something similar for stripe based sites a couple years ago but didn't get too much attention: https://elements.launchscout.com/
Really like what I'm seeing so far. It looks a lot like Sprae: https://github.com/dy/sprae one of my favorite things that no one seems to be paying attention to :) I use it on live-templates, which uses Sprae to connect a template to stateful backend in Elixir over Phoenix Channels: https://github.com/launchscout/live-templates
This sounds awesome. As a GA pilot and software developer, I can tell you that voice comms and the need to work with them will be around for a long time. Just look at all the feet dragging just to get ADSB adopted. I'd love to find out more and possibly get involved. Are you looking for help?
We've definitely experienced chaos when building large React apps. I don't think it's necessarily React's fault (though I'm not particularly a fan), I think the complexity is inherent in managing stage in both a client app and a server app. We've since moved to building apps with Phoenix LiveView and been much more productive. I've also built some libraries to give you the same benefits (single source of state on the server) when serving the front end in Elixir isn't an option: https://github.com/launchscout/live_state.
This sounds like a really excellent product, and I really love the description in this post of how you got there. Not working on anything just this minute that needs it, but I will definitely keep an eye out for opportunities.
The promise of being able to use any library from any language is really quite compelling, and that's what the WASM component model is about for me. It's pretty sad to say this amount of hate TBH
Once again, missing the point of unit testing. Unit testing is about improving the design of the software, and allowing the design to evolve through refactoring (which is effectively impossible without unit testing). E2E or integration tests are for catching bugs
