当今一般都流行脚手架使用,所以一般react\vue\angular官网都有推荐的安装方式,
react有好几种,一般是react-cli或自己配置。
package.json
{ "name": "test", "version": "1.0.0", "description": "测试", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "Webpack-dev-server" }, "author": "zhangzhicheng", "license": "ISC", "dependencies": { "react": "^16.2.0", "react-dom": "^16.2.0" }, "devDependencies": { "babel-cli": "^6.26.0", "babel-core": "^6.26.0", "babel-loader": "^7.1.4", "babel-plugin-react-html-attrs": "^2.1.0", "babel-preset-env": "^1.6.1", "babel-preset-react": "^6.24.1", "css-loader": "^0.28.7", "extract-text-webpack-plugin": "^3.0.2", "html-webpack-plugin": "^2.30.1", "less": "^3.0.1", "less-loader": "^4.1.0", "postcss-loader": "^2.0.9", "style-loader": "^0.19.1", "webpack": "^3.10.0", "webpack-dev-server": "^2.9.7" } }
webpack.config.js
const debug = process.env.NODE_ENV !== "production"; const webpack = require(‘webpack‘); const path = require(‘path‘); module.exports = { entry: ‘./src/index.js‘, output: { path: path.resolve(__dirname, ‘dist‘), filename: ‘bundle.js‘ }, module: { rules: [ { test: /\.js$/, exclude: /(node_modules|bower_components)/, use: { loader: ‘babel-loader‘ } }, { test: /\.css$/, use: [ ‘style-loader‘, { loader: ‘css-loader‘, options: { importLoaders: 1 } }, { loader: ‘postcss-loader‘, options: { ident: ‘postcss‘, plugins: (loader) => [ require(‘autoprefixer‘)() ] } } ] }, { test: /\.less$/, use: [ ‘style-loader‘, { loader: ‘css-loader‘, options: { importLoaders: 1 } }, { loader: ‘postcss-loader‘, options: { ident: ‘postcss‘, plugins: (loader) => [ require(‘autoprefixer‘)() ] } }, ‘less-loader‘, ] } ] }, devServer: { contentBase: path.join(__dirname, "dist"), compress: true, port: 9000, hot: true, inline: true }, plugins: [ new webpack.optimize.DedupePlugin(), new webpack.optimize.OccurrenceOrderPlugin(), new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }), new webpack.HotModuleReplacementPlugin() ] }; /* 以上是使用less+babel+react配置 启动webpack-dev-server配置devServer 基本上配置webpack都去官网和各模块官网复制粘贴就可以了,都有推荐配置 而postcss-loader这个自定义一些css预处理方式,可以和less\sass\stylus配合使用 */ /*如果你使用了一些有着很酷的依赖树的库, 那么它可能存在一些文件是重复的。webpack可以找到这些文件并去重。 这保证了重复的代码不被大包到bundle文件里面去,取而代之的是运行时请求一个封装的函数 webpack.optimize.DedupePlugin() 根据模块调用次数,给模块分配ids,常被调用的ids分配更短的id,使得ids可预测,降低文件大小,该模块推荐使用 OccurrenceOrderPlugin 压缩js UglifyJsPlugin 热替换模块,使用热替换使用的 HotModuleReplacementPlugin */
webpack使用3版本,因为4版本不稳定。
.babelrc
{ "presets": ["react","env"], "plugins": [ "react-html-attrs" ] }
使用react-html-attrs,因为react不能正常使用class,react都是使用ES6 clas类编写组件的和使用jsx,html的class会和ES6的冲突,
所以使用react-html-attrs解决,这就可以使用class在jsx的html里。
