React + Rails를 배우기로 결심했습니다. I는 다음과 같습니다 간단한 구성 요소를 렌더링 할 :React in Rails가 작동하지 않는 컴포넌트 렌더링

는 app.js를

var App = React.createClass({ 
    render: function() { 
    return (
     <div> 
     Hello React first component. 
     </div> 
    ); 
    } 
}); 
ReactDOM.render(
    <App />, 
    document.getElementById('content') 
);

react_controller.rb

class ReactController < ApplicationController 
    def index 
    render component: 'App' 
    end 
end

보기/반응/index.html.erb

<%= react_component 'App' %>

내 화면에 텍스트를 표시하기에 충분하다고 생각합니다.

routes.rb

Rails.application.routes.draw do 
    root 'react#index' 
end

그리고 나는 react-rails 보석을 사용하고 있습니다 : 나는군요. 서버에서

(로컬) 내가 할 (분명히 어딘가에 구문 오류가있다) :

jsx가 (가) javascript로 변환되지 않았습니다. 'config.react.jsx_transform_options'를 가지고 놀아보십시오. –

이 app.jsx하는 app.js의 이름을 바꾸는 시도가. 또한, 부품 과을 수동으로 마운트 할 필요없이 동시에 react_component를 사용하십시오.
