This is a simple OCaml ppx rewriter to use node modules in OCaml.

opam install node_of_ocaml

In your dune file:

(executable
  (name <exe_name>)
  (modes js)
  (libraries js_of_ocaml)
  (preprocess (pps node_of_ocaml js_of_ocaml-ppx)))

If you wish to use a node module, just use this:

let uniq = [%require uniq]

To use the compiled file in your browser you cin use your favorite JavScript bundler.
