私の目標は、起動時にPurescript Thermiteコンポーネントを生成するためにリモートAPIを呼び出すことです。これはcomponentDidMountイベントハンドラが直接的ではないテルミットで使用可能ですが、低いレベルで公開されては、だから私はcomponentDidMountイベントリスナーを追加するcreateReactSpec機能を使用しようが、私はリジッドタイプを含む型の不一致を取得バインディングPurescript反応しPureScript ThermiteコンポーネントにcomponentDidMountイベントリスナーを追加する
を反応させます変数私はそうではありません理解する（私はpurescript/haskellにはかなり新しい）。ここにあなたの助け
ため
おかげでコードです：
module Main where

import DOM.HTML.Types (htmlElementToElement) as DOM

import Data.Foldable (traverse_)
import React (ComponentDidMount, createClass, createFactory, transformState)
import React.DOM as R
import ReactDOM (render)
import Thermite as T
