I guess Bucklescript aims at a smoother integration with the JS ecosystem, which means binding to existing frameworks rather than creating new ones (such as tyxml or Eliom). These are different approaches which make sense for different target audiences.

That said, it is also quite easy to bind to the JS world with js_of_ocaml and nothing forces you to rely on tyxml or Eliom. You can use either the FFI which comes with js_of_ocaml, or gen_js_api ( https://github.com/LexiFi/gen_js_api ) which we have created to abstract OCaml/JS bindings from the underlying OCaml->JS compilation technology (we hope that Buckescript will support gen_js_api). The web client-side frontend of my company is using exclusively gen_js_api + the js_of_ocaml compiler (but not its FFI nor its standard library), which should make it straightforward to port to Buckescript at some point if the need arise.
