I have tried both typescript and cue-lang to generate json configuration for a while and I have to say that I prefer typescript to cue-lang, especially after deno provides native support for typescript.

I don't think Turing complete or not matters a lot for a configuration language. What really matter are the toolchain support and the ability of express complex concept or relationships. Writing typescript with VsCode is a really pleasure and its type system is powerful enough to express complicate concepts. Besides typescript has mature packages systems which cue-lang is not ready yet.

With typescript you can easily do things like reading a json configuration via HTTP and override some varibles to generate the target json file you want, which would be hard to do the same thing with cue-lang.

As a conclusion, I don't think currently cue-lang would be a good solution for configuration generation. But I do believe it would get better in the future if the community keeps working on it.
