Usage

Given some Elm code like

module Main exposing (main)

import Html


main =
    Html.text "Hello from Elm!"

in a build file do

import { compileToModule } from "https://deno.land/x/deno_elm_compiler@0.1.0/compiler.ts";

await compileToModuleString("./src/Main.elm", { output: "./src/elm.js" });

then run your bulid script with Deno

deno run --allow-env --allow-run --allow-write --allow-read build.ts
  • --allow-env is required to pass in ENV variables to the Elm compiler
  • --allow-run is required to allow Deno to run the Elm compiler
  • --allow-write is required for writing a module and for compiling to a string
  • --allow-read is required for compiling to a string

after you can consume your Elm code like any of the following

import Elm from "./src/elm.js";

Elm.Main.init();

//----------- OR ---------------

import { Main } from "./src/elm.js";

Main.init({ node: document.getElementById("elm-root") });

For more details on Elm and Javascript interop, see the Elm docs.

Todo:

  • Add a cli wrapper so you can optionally do deno-elm src/Main.elm --optimize --module --output=src/elm.js
