設定和 Hello World

將 React 新增到你的專案：

meteor npm install --save react react-dom react-mounter

建立 client/helloworld.jsx 檔案以顯示簡單的 React 元件：

import React, { Component } from 'react';
import { mount } from 'react-mounter';

// This component only renders a paragraph containing "Hello World!"
class HelloWorld extends Component {
  render() {
    return <p>Hello World!</p>;
  }
}

// When the client application starts, display the component by mounting it to the DOM.
Meteor.startup(() => {
  mount(HelloWorld);
});
