This project is forked from an earlier version of the ReScript compiler, focused on a deeper integration with the OCaml ecosystem. Such integration makes it easy to share code between backend and frontend using e.g. Dune's virtual libraries.
Melange 1.0 includes a ReScript compatibility layer to maintain compatibility with ReScript syntax - preserving access to ReScript's package ecosystem. Both ReScript and Melange have diverged significantly since then, and this compatibility layer was removed in Melange 2.0.
A small write-up with more details on the motivation behind this project can be found in the announcement blog post. Additional write-ups exist at anmonteiro.substack.com
Below is a quick comparison between Melange and other tools:
Thanks to the ReScript project, its author and maintainer @bobzhang, and its many contributors. Melange is a fork of ReScript, and continues to incorporate patches to ReScript on a regular basis.
Thanks to the OCaml team, obviously, without such a beautiful yet practical language, this project would not exist.
Thanks to Bloomberg and Facebook. The ReScript project began at Bloomberg and was published in 2016; without the support of Bloomberg, it would not have happened. ReScript was funded by Facebook since July 2017.
