Yes. If you don’t need to change the aspect ratio, then that is the approach I would take.
Reading some of the other responses though, I (without knowing anything about what you are trying to build…) would look at phoenix/LiveView first as well. It might not fit the scenario tho!
I’ve been working in React Native for a while (too long)… I would like sort of a drop in replacement for that. It’s possible you need to be Facebook or Google to pull it off but RubyMotion gives me hope.
A similar vision that @boydm has for Scenic. It should work with or without a server.
Also, I definitely want the BEAM for the same reason you’d want the BEAM in embedded. That’s kind of the point. I want to be able to run an Elixir node on the phone.
Actually I like the idea of Scenic. If we can do one super app together, than contains scenic, elixir, erlang and some native control all in one, so the community can distribute their own applet via hex.pm in source form. So this super app will access hex.pm, browse available scenic apps and download compile and play the app.
If we have that, before long we will have silly games mushroom all over!
