webpack打包react项目的实现方法

{
 "presets":["react","es2015"]
}

var path = require('path');
var webpack = require('webpack');
var HtmlwebpackPlugin = require('html-webpack-plugin');
var ROOT_PATH = path.resolve(__dirname);
var BUILD_PATH = path.resolve(ROOT_PATH, 'build');
var APP_PATH = path.resolve(ROOT_PATH, 'app');

module.exports = {
 entry: {
 app: path.resolve(APP_PATH, 'app.js')
 },
 output: {
 path: BUILD_PATH,
 filename: '[name].bundle.js'
 },
 resolve:{
 extensions:['','.js','.jsx'],
 root:APP_PATH
 },
 module:{
 loaders:[
  {
  test: /\.js"text-align: center">

app是项目组件文件夹，test是测试文件
list.js代码


import React from 'react';
import uuid from 'uuid';
import ListItem from '../listItem/listItem';

class List extends React.Component {
 constructor(props) {
 super(props);
 this.state = {
  items: []
 }
 }
 handleclick() {
 const value = this.refs.addlist.value;
 const str = {
  id: uuid.v1(),
  text: value
 }
 let items = this.state.items;
 items = [...items, str];//合并数值
 this.setState({
  items
 })
 }
 //删除其中的
 deleteItem(id) {
 this.setState({
  items: this.state.items.filter(
  result => result.id !== id
  ),
 });
 }
 render() {
 const ListIt = this.state.items.map(item => {
  return (
  <ListItem key={item.id} name={item} onDelete={this.deleteItem.bind(this)} />
  );
 });
 return (
  <div className="list">
  <input type="text" placeholder="请输入" ref="addlist" />
  <button className="addbutton" onClick={this.handleclick.bind(this)}>添加值</button>
  <ul>
   {ListIt}
  </ul>
  </div>
 );
 }
}

export default List;




listitem.js


import React from 'react';

class ListItem extends React.Component {
 render() {
 const text = this.props.name;
 return (
  <li onClick={() => this.props.onDelete(text.id)}>
  <span>{text.text}</span>
  </li>
 )
 }
}

export default ListItem;




app.js文件


import React from 'react';
import ReactDOM from 'react-dom';
import List from './list/list';

const app = document.createElement('div');
document.body.appendChild(app);
ReactDOM.render(<List />, app);

运行项目nam run dev
10)后续会有基于这个demo的测试enzyme库的使用，代码检测aslant，flux的使用，redux的使用
