Description

gen_js_api aims at simplifying the creation of OCaml bindings for JavaScript libraries. Authors of bindings write OCaml signatures for JavaScript libraries and the tool generates the actual binding code with a combination of implicit conventions and explicit annotations.

gen_js_api is to be used with the js_of_ocaml compiler.

README

gen_js_api: easy OCaml bindings for JavaScript libraries

Overview

gen_js_api aims at simplifying the creation of OCaml bindings for JavaScript libraries. It must currently be used with the js_of_ocaml compiler, although other ways to run OCaml code "against" JavaScript might be supported later with the same binding definitions (for instance, Bucklescript, or direct embedding of a JS engine in a native OCaml application).

gen_js_api is based on the following ideas:

  • Authors of bindings write OCaml signatures for JavaScript libraries and the tool generates the actual binding code with a combination of implicit conventions and explicit annotations.

  • The generated binding code takes care of translating values between OCaml and JavaScript and of dealing with JavaScript calling conventions.

  • All syntactic processing is done by authors of bindings: the client code is normal OCaml code and does not depend on custom syntax nor on JS-specific types.

gen_js_api can be used in two complementary ways:

Examples

The repository contains some examples of OCaml bindings to JavaScript libraries created with gen_js_api:
