prolink-connect VS Papercups

Technically the software covers a _lot_ of the stack

* Reverse engineered Pioneer DJ gear's proprietary low-level network protocol to masquerade as one and receive state updates from the physical DJ gear on the network. The implementation is a typescript library [0].

* Implements a NFS client in typescript to download the music metadata database off of the USB drives DJs plug into the DJ gear.

* Uses kaitai-struct [01 to generate parsing code for the (very old) DeviceSQL database files that the music database use.

* The application is built as an electron app, react + emotion (styled-components) + framer-motion (animated components), and mobx with serializr to handle IPC between the main thread and renderer.

* Uses websockets with the same serialization driver to communicate updates to the overlay browser window which is rendered in OBS (or another livestreaming studio software)

I've just started working on an API backend for it as well, where the same serialization backend is used to publish users app store to a central server which will be useful for features like "Live user track voting", where you pick a playlist on your gear to expose to users, and they can vote on tracks.

The best language for the task at hand, when presented with time constraints, is the one that you already know well. OP said in the article that they authored Papercups [1]. Adopting Elixir for a websocket-push service makes a lot of sense, then. However, why don't you learn Elixir, some OTP, and then reconsider that question? You could be missing out.

Phoneix - Elixir

We're a live message tool and it is basically what Elixir is built for https://github.com/papercups-io/papercups.

The Elixir community has been great and incredibly friendly. I originally was worried about the size of the community but that hasn't been an issue the community has been super helpful. I also think the annual stackoverflow usage surveys are very misleading because most of the community's questions get asked in ElixirForum and not on Stackoverflow.

Phoneix is the web framework of Elixir which is very similar to Rails but minus a lot of the magic has been very helpful for our productivity as well.

If I had to built another service that is websocket heavy I would definitely use Elixir. Even if it was a standard crud app I would still most likely choose Elixir.
