My problem is with npm and nodejs dependency, for writing CLI, which essentially means you have to install nodejs and is probably only really useful for nodejs developers.
My purpose in writing Vorpal is to make building CLIs accessible to a wider audience. While haters will hate JS, it nevertheless has a very broad use and accessibility.
Since every up-to-date Linux system is shipped with Python, and argparse is part of the stdlib, I don't need to worry about argparse not being available. NodeJs adoption is going up, but if someone is building a CLI for a Rust project using Vorpal, then I have to install another piece of software and bloat my local system. Imagine this goes into my docker container it means the overall size of my container will increase. Of course I typically also install a bunch of packages along with my Python project anyway, like requests library, but because these libraries are typically needed for my backend anyway, the CLI's dependency on requests library is debt free. But in the case of me writing a Rust / Go / Python project but shipping a NodeJS CLI version, that's pretty insane. But don't take this the wrong way, I will write NodeJs and I will look at your library. You have great work, but I want to offer you my opinion on why few people outside of NodeJs will use this to build CLI for their X-language project.
I'm yet to encounter those.
