React开发环境搭建

1 查看上一篇文章,并按照步骤来

2 自动打包(有需要再添加)

webpack.config.js  添加 watch:true

3 npm安装react相关

--save-dev  react

      react-dom

--save  babel-preset-react 

设置 webpack.config.js  ==>  query: {presets: ['es2015','react']}

4 demo文件

入口:a.js

import React from "react";
import ReactDOM from "react-dom";
import Hello from "./hello";
ReactDOM.render(
  <Hello />,
  document.querySelector('#app')
);

引用:hello.js

import React from "react";
class Hello extends React.Component{
  render() {
    return (
      <div>
          Hello, World!
      </div>
    )
  }
}
export default Hello;

5 编译,运行

webpack编译下,webpack-dev-server服务器,打开 http://127.0.0.1:8080/dist/

ok!
