styled-ppx
styled-ppx is the ppx that brings typed styled components to Reason, OCaml and ReScript.
Build on top of emotion, it allows you to style apps safe, quickly, performant and as you always done it.
Allows you to create React Components with type-safe style definitions that don't rely on a different DSL than CSS.

Editor Support
One of the downsites of using a ppx
is their editor support, we provide a VSCode extension that brings syntax highlight. This can include in the future, CSS autocomplete and other CSS-related extensions.
Install the VSCode extension: VSCode Extension
