Is it going strong? I'm evaluating it for a new project. I'm considering it together with Clara[0]. However, it does give a vibe that it's not as mainstream as it was before and that the ecosystem is more sparse than what is once was. I'm not trying to troll. I want to choose it. It seems like a good engineering decision to me, but if it's nosediving in popularity and contributors, this might bite me back in the near…
I found myself frustrated a lot when I used it two years ago. A lot of abandoned libraries. There's not a huge ecosystem around it compared to golang and other popular languages, but there's probably enough that it's a viable option if you really want to work with the language.
The one example I can think of where that's emphatically not true is clojure-android, which was tightly coupled to the Android SDK and did not remain usable after the main developer moved on. The Android SDK does not share the aforementioned traits.
