eio_js - Eio for JavaScript environments

The following packages are provided:

You can use Eio_brr.start or Js_of_ocaml_eio.Eio_js.start to execute a function asynchronously in a context where Eio operations can be performed.

Here is a short example using Eio_brr.

let counter = get_element "counter" in
let text = get_element "text" in
let output = get_element "output" in
Eio_brr.start @@ fun () ->
Fiber.both
  (fun () ->
    (* A little text editor *)
    while true do
      let ev = Eio_brr.Ev.next Ev.keyup (El.as_target text) in
      let target = Jv.get (Ev.to_jv ev) "target" in
      let text = Jv.get target "value" |> Jv.to_jstr in
      El.set_children output [ El.txt text ]
    done)
  (fun () ->
    (* A little timer counting up *)
    let i = ref 0 in
    while true do
      El.set_children counter [ El.txt' (string_of_int !i ^ "s") ];
      Eio_brr.G.set_timeout ~ms:1000;
      incr i
    done)
