Hey everyone! I’ve been working on a small poker planning app recently.
I use it with my customers as we are all working remotely due to COVID…
I thought it might help some other teams out there, so I took some time to clean up the repo (in case someone finds it useful as an example 
) and pushed it to GitHub.
For the technical part, it only uses LiveView, Presence, and PubSub (no database, Redis, or JS, though I might have to add some to copy the game URL into the clipboard some day ^^).
The game logic is about 100 lines (+ 60 if you add the view helpers).
I included some pointers to the interesting files in the README.
The game is also completely decentralized and lives entirely in the LiveView.
The initial implementation used GenServer to keep the game state and handle round events. Then I realized it wasn’t necessary, thanks to Presence already doing all the job of broadcasting and synchronizing the state (aka “the votes”).
Everything else is done in the LiveView, which is what I found interesting as it made the whole app much more straightforward (even if we shouldn’t put too many things in the Presence 
).
Hopefully, this might be inspiring to the curious people here 
.
It took about half a day to release & deploy the first version (+ some more hours to add a Readme, some open graph meta, and hide all the signing salts in env variables before making the repo public ).
It was quite a fun experience all along!
Oh, and the docker image is 11MB 
.
You can try it live here, or check out the source code on GitHub.
I hope you’ll like it!
