oc-template-elm

Elm template for the OpenComponents template system

Ports

Your Elm component will have access to two ports by default, if you want to use them.

-- To do a oc.getData request passing your properties
port getData : E.Value -> Cmd msg

-- A listener after the oc.getData request finishes. It will be up to you to decode errors you may get.
port dataReceiver : (E.Value -> msg) -> Sub msg

Custom ports

So what can you do if you want to have extra custom ports? (Maybe to listen to OC events). In that case you can point your entry as a javascript file.

{
  "oc": {
    "files": {
      "data": "src/server.ts",
      "template": {
        "src": "src/index.js",
        "type": "oc-template-elm"
      }
    }
  }
}

Then, on that file, just export default an object that will take two parameters: program with your Elm main program and js with a function that takes the elm app as a parameter where you can set whatever you want

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

export default {
  js: (app) => {
    window.oc.events.on("myEvent", (event) => {
      // Elm will get event data on that port!
      app.ports.myPortReceiver.send(event.data);
    });
  },
  program: Elm.Main,
};
