Elm 0.17 port 筆記

ADT

port 不能使用 ADT，所以任何有巢狀結構的的資料在 port 都會遇到問題。目前的解法是在 outcome 的地方先用 JSON.stringify 轉成 String，income 再用 JSON.parse 轉成 Maybe a（噴 error 的時候就是 Nothing，這個解法有點問題，暫時先這樣 :p）

Electron、Elm 搭配使用

Electron 的 Browser 端

const callbacks = {};
let callbackId = 0;

glbale.electron = window.electron = function (event, args, cb) {
  // 產生 id 是為了讓之後 done 事件被觸發時能夠找到對應的 callback function
