webpack入门级配置（最新）
目前最的正式版本是：4.31.0，推荐使用本地安装，webpack官网-指南
1.初始化
- 确认node 的版本号
node -v - 新建一个项目文件夹
mkdir demo - 初始化
npm init -y - npm 安装 webpack webpack-cli --save-dev
- 在项目文件夹下新建一个src文件夹，src文件夹包含index.js,index.html
- 新建webpack配置文件 webpack.config.js
const path = require('path');module.exports = { entry:'./src/index.js'. ouyput:{ path: path.resolve(__dirname,'dist'), filename: 'bundle.js', }}安装 webpack-dev-server
- 本地安装webpack-dev-server
npm i webpack-dev-server -D - 找到package.json文件，搜索scripts，添加
"dev": "webpack-dev-server --open --port 3000 --contentBase src --hot"代码 - 此时在命令行运行
npm run dev,即可打包文件
安装html-webpack-plugin
- 命令行运行
npm install --save-dev html-webpack-plugin - 在webpack配置文件添加配置信息
const HtmlWebpackPlugin = require('html-webpack-plugin');plugins:[new HtmlWebpackPlugin({template:'./dist/index.html'})]
加载css
- 命令行运行
npm install --save-dev style-loader css-loader - 配置文件配置
module:{reules:[{test:/\.css$/,use:['style-loader','css-loader']}]}
安装babel-loader
- 命令行运行
npm install -D babel-loader @babel/core @babel/preset-env webpack - 配置文件配置
module: { rules: [ { test: /\.js$/, exclude: /node_modules/, use: { loader: 'babel-loader', options: { presets: ['@babel/preset-env'] } } } ]}- 运行
npm install -D @babel/plugin-transform-runtime - 配置文件
use: { loader: 'babel-loader', options: { presets: ['@babel/preset-env'], plugins: ['@babel/plugin-transform-runtime'] } }使用vue
- 命令行运行
npm i vue -D - 配置文件配置
# const VueLoaderPlugin = require('vue-loader/lib/plugin');# resolve:{ alias:{ 'vue$':"vue/dist/vue.esm.js" } } 安装vue-loader
- 命令行
npm install -D vue-loader vue-template-compiler - 配置文件
+ const VueLoaderPlugin = require('vue-loader/lib/plugin');- rules: [ // ... 其它规则 { test: /\.vue$/, loader: 'vue-loader' } ] - plugins: [ // 引入这个插件！ new VueLoaderPlugin() ]附上源代码
webpack.config.js
const path = require('path');const VueLoaderPlugin = require('vue-loader/lib/plugin');const HtmlWebpackPlugin = require('html-webpack-plugin');module.exports = { entry: './src/index.js', output: { path: path.resolve(__dirname,'dist'), filename: 'bundle.js', }, plugins:[ new VueLoaderPlugin(), new HtmlWebpackPlugin({ template:'./src/index.html' }), ], module:{ rules:[ { test: /\.css$/, use: [ 'style-loader', 'css-loader' ] }, { test:/\.(png|svg|ipg|gif)$/, use:['file-loader'] }, { test:/\.vue$/, loader:'vue-loader' }, { test: /\.js$/, exclude: /node_modules/, use: { loader: 'babel-loader', options: { presets: ['@babel/preset-env'], plugins: ['@babel/plugin-transform-runtime'] } } }, ] }, resolve:{ alias:{ 'vue$':"vue/dist/vue.esm.js" } }}package.json
