Question

我正在尝试使用NPM创建一个简单的页面并做出反应。

index.html文件：

<html lang="en">
  <head>
    <meta charset="utf-8">
    <title> Flux Comment Box </title>
  </head>
  <body>
    <section id="react"></section>
    <script src="js/bundle.js"></script>
  </body>
</html>

./ JS / app.js

var CommentBox = require('./components/CommentBox.react');
var React = require('react');
window.React = React;

React.render( <CommentBox />, document.getElementById('react'));

./组件/ CommentBox.react.js

var CommentStore = require('../stores/CommentStore');
var React = require('react');
var CommentBox = React.createClass ({
  render: function () {
    return (
      <div> HI </div>
    );
  },
});

module.exports(CommentBox);

当我执行“npm start”时（我的package.json应该没问题，我会在下面发布），它说

2870222 bytes written to js/bundle.js (2.44 seconds)

但index.html是一个没有错误或警告的空白页面。怎么了？

供参考，这是我的package.json

Answer 1

1. for render 你应该使用 ReactDOM insact of React

var React = require('react');
var ReactDOM = require('react-dom');

ReactDOM.render( <CommentBox />, document.getElementById('react'));

2. 重新设置已弃用：改为使用 babelify （确保您使用babel-preset-react配置了Babel）

页面没有显示在npm上开始使用节点，做出反应
