环境准备工作：windows7、webStorm 2017.1.4、Nodejs 8.7.0、npm 5.4.2
PS:安装的时我们都带上版本，这样即便webpack版本发生变化，也不会出现版本问题。
初始化package.json文件
npm init
npm安装react、react-dom包
npm install react@16.3.0 react-dom@16.3.0 --save
或者
npm i -S react@16.3.0 react-dom@16.3.0
npm安装webpack、webpack-cli等包
npm install webpack@4.4.1 webpack-cli@2.0.13 webpack-dev-server@3.1.1 webpack-merge@4.1.2 babel-cli@6.26.0 babel-preset-env@1.6.1 babel-preset-react@6.24.1 babel-preset-react-hmre@1.1.1 babel-loader@7.1.4 --save-dev
或者
npm i -D webpack@4.4.1 webpack-cli@2.0.13 webpack-dev-server@3.1.1 webpack-merge@4.1.2 babel-cli@6.26.0 babel-preset-env@1.6.1 babel-preset-react@6.24.1 babel-preset-react-hmre@1.1.1 babel-loader@7.1.4
文件夹结构
各个文件的内容
Index.jsx
import React from 'react'; class Index extends React.Component { render() { return ( <div> 这是首页women修改一下 </div> ); } } export default Index;
index.js
import React from 'react'; import ReactDOM from 'react-dom'; import Index from './views/Index'; ReactDOM.render(<Index/>, document.getElementById('app'));
index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta content="telephone=no" name="format-detection"> <title>react</title> </head> <body> <div id="app"></div> <script type=text/javascript src=js/index.js></script> </body> </html>
base.config.js
let config = { entry: { 'index':'./src/index.js' }, resolve: { extensions: [".js", ".json", ".jsx", ".css"], } }; module.exports = config;
dev.config.js
const webpack = require('webpack');//引入webpack
const opn = require('opn');//打开浏览器
const merge = require('webpack-merge');//webpack配置文件合并
const path = require("path");
const baseWebpackConfig = require("./base.config");//基础配置
const webpackFile = require("./file.config");//一些路径配置
let config = merge(baseWebpackConfig, {
/*设置开发环境*/
mode: 'development',
output: {
path: path.resolve(webpackFile.devDirectory),
filename: 'js/[name].js',
chunkFilename: "js/[name].js",
publicPath: ''
},
plugins: [
/*设置热更新*/
new webpack.HotModuleReplacementPlugin(),
],
module: {
rules: [
{
test: /.(js|jsx)$/,
use: [
'babel-loader',
],
include: [
path.resolve(__dirname, "../src")
],
exclude: [
path.resolve(__dirname, "../node_modules")
],
}
]
},
/*设置api转发*/
devServer: {
host: '0.0.0.0',
port: 8080,
hot: true,
inline: true,
contentBase: path.resolve(webpackFile.devDirectory),
historyApiFallback: true,
disableHostCheck: true,
proxy: [
{
context: ['/api/**', '/u/**'],
target: 'http://127.0.0.1:8080/',
secure: false
}
],
/*打开浏览器 并打开本项目网址*/
after() {
opn('http://localhost:' + this.port);
}
}
});
module.exports = config;
file.config.js
module.exports = { devDirectory:'static',/*开发目录*/ proDirectory:'dist',/*发布目录*/ resource:'resource',/*静态资源*/ };
package.json文件中添加脚本命令
"dev": "webpack-dev-server --devtool eval --progress --colors --profile --config webpack/dev.config.js"
最后执行运行命令
