Hi there, I’m considering to migrate from ruby (rails) to crystal (amber), but the discusion is more tied to crystal than a framework, what are the cons right now at a language level? There’s anything I need to be worried about about some stuff that ruby currently has and crystal is missing? I’m not…

You can check [Mini Review] Giving up on Crystal for some cons. Exact problems mentioned there are debatable, but the points in general are (imho) truthy. Type system. Background with strongly typed languages will help, but there still will be times when you are fighting against type system. The …

For me the only issue I see right now is the version breaking changes, about the compile times, type system, etc I’m not concerned too much, I’ve been playing with rust for few months and I’m kinda used to thing about the types etc, also I fall in love in having static typed, even that I don’t want …

Maybe you can try it with a small service and see how it goes.

I have not used amber yet, so I can’t say anything about that end of things. About Crystal itself, I would suggest just doing it. I’m very much in love with the type system it provides and the great standard library. Using crystal also removes the problem of installing and maintaining a ruby insta…

If you want to stick with Ruby there is always the new Sorbet static type checker. However if you do want to switch to Crystal, which I am always a proponent for you have to know a few things. The compiler is magical, but also a massive pain in the ass. By this I mean that you will be fighting wi…

@girng I didn’t wanted to commit yet to use in a project, so I’m waiting to find the right pet project to test this out (something small that could possibly take only a few hours to convert to ruby as a fallback, if needed), some things that pushed me away to trying it was the breaking changes (with…

@norman784 Good to know! FWIW, it’s pretty stable! I know @sdogruyol uses Crystal in production. And I’m using it for a soon released online aRPG. I’ve seen some other people in gitter mention they use it at their company as well. But it’s understandable you want to wait for a firm release :) I hop…

Hi ! At Plezi we use Crystal on production for a little service. This service should be bigger, but the lack of good MongoDB ORM stopped us. Also, for side projects, I use Crystal (Amber) and the SQL ORM are bad too, it’s difficult to build complexe queries and fetch results, and all ORM are Acti…
