I’ve noticed that this project is written in Crystal, is Crystal production ready?
I've looked into it months ago and it seems that there are a lot of breaking changes on every release and this scares me from using it.
I'm not sure I would recommend it for something on the scale of Apple or Microsoft, but for a personal project like this I've found it a very enjoyable experience.
Don't worry, as soon as Auntie Apple, Uncle Uber or someone as large as Mr Microsoft goes and adopts Crystal as soon as it reaches 1.0, then we will all immediately run to learning it just like we all did for Kubernetes, Docker, Elixir, Go and finally with its great success and without any formal introduction, we have all wanted to purse learning Mozilla's new and most excellent general-purpose programming language:
Rust.
