源文件在src目录下，打包后的文件在dist目录下。
2.webpack.config.js
说明：
1.涉及到的插件需要npm install安装；
2.html-webpack-plugin创建服务于 webpack bundle 的 HTML 文件；
3.clean-webpack-plugin清除dist目录重复的文件；
4.extract-text-webpack-plugin分离css文件。
var path = require('path'); var webpack = require('webpack'); var HtmlWebpackPlugin = require('html-webpack-plugin'); var CleanWebpackPlugin = require('clean-webpack-plugin'); var ExtractTextPlugin = require("extract-text-webpack-plugin"); var UglifyJsPlugin = webpack.optimize.UglifyJsPlugin; var config = { context: path.resolve(__dirname, './src'), entry: { app: './main.js' }, output: { path: path.resolve(__dirname, './dist'), filename: '[name].bundle.js' }, devtool: 'cheap-module-eval-source-map', module: { rules: [ { test: /\.jsx?$/, exclude: /node_modules/, loader: 'babel-loader' }, { test: /\.css$/, use: ExtractTextPlugin.extract({ fallback: "style-loader", use: ["css-loader","postcss-loader"] }) }, { test: /\.less$/, use: ["style-loader","css-loader","less-loader"] }, { test: /\.(png|jpg)$/, loader: 'url-loader', options: { limit: 8129 } } ] }, devServer:{ historyApiFallback: true, host:'0.0.0.0', hot: true, //HMR模式 inline: true,//实时刷新 port: 8181 // 修改端口，一般默认是8080 }, resolve: { extensions: ['.js', '.jsx', '.css'], modules: [path.resolve(__dirname, './src'), 'node_modules'] }, plugins: [ new webpack.HotModuleReplacementPlugin(), new UglifyJsPlugin({ sourceMap: true }), new webpack.LoaderOptionsPlugin({ minimize: true, debug: true }), new HtmlWebpackPlugin({ template:'./templateIndex.html' }), new ExtractTextPlugin({ filename: '[name].[hash].css', disable: false, allChunks: true, }), new CleanWebpackPlugin(['dist']) ], } module.exports = config; // webpack里面配置的bundle.js需要手动打包才会变化,目录可以由自己指定; // webpack-dev-server自动检测变化自动打包的是开发环境下的bundle.js,打包路径由contentBase决定,两个文件是不一样的.
3.postcss.config.js(Autoprefixer)
module.exports = { plugins: { 'autoprefixer': {browsers: 'last 5 version'} } } // 兼容最新的5个浏览器版本
4.新建.babelrc
{ "presets": ['es2015','react','stage-3'] }
5.index.html
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>React Project</title> </head> <body> <div></div> <script src="https://www.jb51.net/app.bundle.js"></script> </body> </html>
6.package.json
npm install 或 yarn -> 安装模块，npm run build -> 打包，npm start -> 启动localhost:8181

7.main.js:入口文件
import React from 'react' import { render } from 'react-dom'; import $ from 'jquery'; import Demo1 from './js/demo1.js'; // import Demo2 from './js/demo2.js'; render(<Demo1 title="这是提示" />, $('#content')[0]); // render(<Demo2 myName="园中桥" sex="female"/>, $('#content')[0]);
8.templateIndex.html
打包后的模板index文件，插件html-webpack-plugin的template指定的目录。
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>Template Index html</title> </head> <body> <div></div> </body> </html>
