Brr is a toolkit for programming browsers in OCaml with the js_of_ocaml compiler. It provides:

• Interfaces to a selection of browser APIs.
• Note based reactive support (optional and experimental).
• An OCaml console developer tool for live interaction with programs running in web pages.
• A JavaScript FFI for idiomatic OCaml programming.

Brr is distributed under the ISC license. It depends on Note and on the js_of_ocaml compiler and runtime – but not on its libraries or syntax extension.

Brr can be installed with opam:

opam install brr

If you don't use opam consult the opam file for build instructions.

The documentation can be consulted online or via odig doc brr.

Not much for now. A few basic programs are in the [test suite][test].

An implementation of the TodoMVC application with brr.note is in todomvc.ml.
