What I've Learned (So Far) Building Online Mini Games with Elixir and Swift

In my own projects I've found the feedback loop to be much slower in native mobile apps compared to web. For web apps my workflow has involved lots of human verification just through using the app myself and testing out the latest features/fixes. Sometimes I get the agent itself to do this before I do using Codex's chrome extension. This same process on mobile is a lot slower. How have you approached this aspect? Have you figured out a way to get the agent to control an emulator?

My post about my recent project, Migo Games

I’ve never thought about how the room model matches the LiveView socket model before. Which socket library are you using?

Maestro but honestly you should always be testing on real devices

was expecting a bit more substance but always interesting to read different approaches.

but I do wonder if BEAM is a bit of an overkill, even fly.io (known among developer threads to be very unreliable uptime) wouldn't be my first pick.

Cloudflare Durable Objects really is generous, not often can you get replicated database and realtime sync for such low barrier in cost and implementation.

I do wonder tho what Cloudflare's ultimate game is, as I'd imagine once they corner the market and practically everything is running off it, wouldn't be hard to say raise the $5/month to something higher.

I should've said more about the tech. I will later. The server is in NJ. If you're in the EU the game might really lag. Sorry!

You mention it is possible to play via Web, but all links just lead to pages which point to Apple's app store. Game over for Android and the web?

Really interested in hearing more about the architecture. Especially (1) why you chose Elixir, Phoenix over TS (2) how you dealt with real-time multiplayer.

Aside: The links to the web game in the post don't lead to being able to play.

Phoenix is delightfully fast and not having to deal with two entirely different application stacks where your application is split down the middle (or the javascript ecosystem) is a breath of fresh air.
