Natif
Bsb-native is a fork of BuckleScript's bsb that compiles to native OCaml instead.
Esy is a project package manager for native Reason. - Esy can install packages from opam. - Esy lets you install esy packages from npm and publish esy packages to npm..
Note: Esy works on all three platforms (OSX, Linux, Windows) but Windows support is still considered "beta".
There is not much support for combining these two workflows. esy begins with a "native-first" workflow, and bsb-native begins with a "bucklescript first" workflow - the main difference being that esy has tighter integration with the existing native ecosystem, and bsb-native has tighter integration with the bucklescript ecosystem.
