Chill-Netcat (work in progress)

A deliberately limited Netcat implementation (UDP only).

An exercise in building a network enabled systems program / unikernel with OCaml / MirageOS.

With minimal network related dependencies included the resulting binary has a size of ~3.3MB (on MacOS).

This project is based on the highly instructional "Hello MirageOS World" guide and mirage-skeleton code examples.

You can also watch my talk at the first Vienna ReasonML meetup.


Check the official MirageOS installation guide.
