Optique just crossed 600 GitHub stars!
For those unfamiliar: #Optique is a #CLI parsing library for #TypeScript that takes a parser combinator approach, inspired by Haskell's optparse-applicative. The core idea is “parse, don't validate”—you express constraints like mutually exclusive options or dependent flags through types, and TypeScript infers the rest automatically. No runtime validation boilerplate needed.
It started as something I built out of frustration while working on Fedify, an ActivityPub framework, when no existing CLI library could express the constraints I needed in a type-safe way. Apparently I wasn't the only one who felt that way.
Thank you all for the support.
