* [Caml-list] Beginners Question for js_of_ocaml @ 2017-01-13 23:58 Helmut Brandl 2017-01-14 7:49 ` Nicolás Ojeda Bär 0 siblings, 1 reply; 5+ messages in thread From: Helmut Brandl @ 2017-01-13 23:58 UTC (permalink / raw) To: Caml List Hello List, I am trying to use js_of_ocaml to compile my ocaml project for the nodejs ecosystem. Since js_of_ocaml does not compile calls to the 'unix' library I have to call some javascript functions directly from ocaml. All I need is to be able to call the javascript functions - readdirSync - mkdirSync - rmdirSync - statSync and receive the results in ocaml. I have looked into the documentation and into the examples, but I have not found a way on how to do this. All examples are for use in the browser. Maybe its a stupid question and it is so simple that I, as a beginner in js_of_ocaml, just don't see it. Can anybody give me a hint? Thanks in advance.

It works nearly as you explained. I have to get first the fs object and then make a method call and not a function call. As you explained there is all information necessary in the documentation. I just did not find it in my first attempt.
