Webpack est un outil frontal qui permet de charger, prétraiter et empaqueter chaque module. Il possède toutes les fonctions de base de Grunt ou de Gulp.
J'ai déjà utilisé gulp pour empaqueter et compresser les css et js de la page. La configuration est simple, mais elle est trop triviale et gênante. Lors de l'utilisation de sass, il est facile d'importer. le fichier sass directement dans sass. Erreur signalée (je ne sais pas ce qui se passe)
Ce qui m'attire dans webpack : modularité, chargement à la demande, compression css, styles en ligne, et styles indépendants. Compresser js, compresser la page

Installez vous-même la version 2.0 du webpack (certaines choses nécessitent une attention particulière)
Installez le nœud de test et npm
1 $ node -v2 v6.11.0
$ npm -v3.10.10
npm init -y
//全局安装 npm install -g webpack //安装到你的项目目录 npm install --save-dev webpack
"scripts": {"build": "webpack --profile --progress --colors --display-error-details","dev": "webpack --display-modules --profile --progress --colors --display-error-details","dev-hrm": "webpack-dev-server --config" },
// 开发模式npm run dev// 热更新模式npm run dev-hrm// 发布模式npm run build
module.exports = {entrée :{
Principal : "./src/app.js?1.1.11",
} ,
//Le seul fichier d'entrée qui a été mentionné à plusieurs reprises fois
+ "/dist",filename: "js/[name].js?1.1.11",
npm install --save-dev html-webpack-plugin
plugins:[new htmlWebpackPlugin({ filename:'index.html', template:'index.html', inject:'body', title:'首页', }), ]
<br/>Les chargeurs doivent être installés séparément et configurés sous le mot-clé
sous webpack.config.js. Les options de configuration des chargeurs incluent les aspects suivants : modules
<br/><.>
test
loader
include/exclude
: Fournir des options de configuration supplémentaires pour les chargeurs (facultatif)
Babelquery
Les normes JavaScript de nouvelle génération (ES6, ES7), qui ne sont actuellement pas entièrement implémentées par le support des navigateurs actuels
<br/>
// npm一次性安装多个依赖模块,模块之间用空格隔开npm install --save-dev babel-core babel-loader babel-preset-es2015 babel-preset-react
{ test: /\.js$/, loader: 'babel-loader', include: path.resolve(__dirname,'src'), exclude: path.resolve(__dirname,'node_modules'), query:{ presets:["es2015"] } }
npm install --save-dev style-loader css-loader
{ test:/\.css$/, loader: [ 'style-loader', { loader: 'css-loader', options: { importLoaders: 1 } }, 'postcss-loader'] }
