If this were implemented in a language with fewer dependencies, it'd be great.
Another option that appears to work well is to use Deno. I tried on my machine and it worked great. Only downside is the executable size is beefy. Could be about 70-105MB, or roughly 30MB compressed.
I don't know if that still sounds attractive? A 30MB download from Github, and then uncompressed to 100MB, and no other dependencies? (Most of it would be the Deno runtime, with only about 300KB being Reladraw)
