webpack4 化繁为简(二)
标签:
JavaScript
书接上文,继续干,配置一些常用的插件使支持
uglifyjs js压缩插件
webpack默认已经有uglifyjs,所以只需要引入就可以使用.
在webpack.config.js中配置:
const path=require('path'); const webpackDevServer=require('webpack-dev-server'); const extractTextWebpackPlugin=require('extract-text-webpack-plugin'); const uglify=require('uglifyjs-webpack-plugin'); module.exports={ mode:"development", entry:[ path.join(__dirname,'./src/entry.js'), path.join(__dirname,'./src/entry1.js'), ], output:{ path:path.join(__dirname,'dist'), filename:'[name].js' }, module:{ rules:[ { test:/\.css$/, use:extractTextWebpackPlugin.extract({ fallback:"style-loader", use: ['css-loader',] }) } ] }, plugins:[ new extractTextWebpackPlugin({ filename:'index.css' }), new uglify() ], devServer:{ contentBase:path.join(__dirname,'dist'), host:'localhost', compress:true, port:8888 } }
2.html-webpack-plugin 生成html
将dist的目录下面的index.html移入src目录,并且删除script 以及css 的引入标签,然
后安装html-webpack-plugin包。
cnpm install --save-dev html-webpack-plugin
在webpack.config.js中修改如下
const path=require('path'); const webpackDevServer=require('webpack-dev-server'); const extractTextWebpackPlugin=require('extract-text-webpack-plugin'); const uglify=require('uglifyjs-webpack-plugin'); const htmlWebpackPlugin=require('html-webpack-plugin') module.exports={ mode:"development", entry:[ path.join(__dirname,'./src/entry.js'), path.join(__dirname,'./src/entry1.js'), ], output:{ path:path.join(__dirname,'dist'), filename:'[name].js' }, module:{ rules:[ { test:/\.css$/, use:extractTextWebpackPlugin.extract({ fallback:"style-loader", use: ['css-loader',] }) } ] }, plugins:[ new extractTextWebpackPlugin({ filename:'index.css' }), new uglify(), new htmlWebpackPlugin({ minify:{ removeAttributeQuotes:true }, hash:true, template:path.join(__dirname,'./src/index.html') }) ], devServer:{ contentBase:path.join(__dirname,'dist'), host:'localhost', compress:true, port:8888 } }
file-loader、url-loader html-withimg-loader图片处理以及打包
在src下面建一个images的文件夹放入一张图片
分别在css和html 的img标签中引入
cnpm install --save-dev file-loader url-loader
cnpm install --save html-withimg-loader
webpack.config.js修改如下:
const path=require('path'); const webpackDevServer=require('webpack-dev-server'); const extractTextWebpackPlugin=require('extract-text-webpack-plugin'); const uglify=require('uglifyjs-webpack-plugin'); const htmlWebpackPlugin=require('html-webpack-plugin'); const webset={ publicPath:'192.168.0.175:8888/' } module.exports={ mode:"development", entry:[ path.join(__dirname,'./src/entry.js'), path.join(__dirname,'./src/entry1.js'), ], output:{ path:path.join(__dirname,'dist'), filename:'[name].js' }, module:{ rules:[ { test:/\.css$/, use:extractTextWebpackPlugin.extract({ fallback:"style-loader", use: ['css-loader',] }) }, { test:/\.(png|jpg|gif)$/, use:[{ loader:'url-loader', options:{ limit:8192, outputPath:'images/' } }] }, { test:/\.(htm|html)$/i, use:['html-withimg-loader'] } ] }, plugins:[ new extractTextWebpackPlugin({ filename:'index.css' }), new uglify(), new htmlWebpackPlugin({ minify:{ removeAttributeQuotes:true }, hash:true, template:path.join(__dirname,'./src/index.html') }) ], devServer:{ contentBase:path.join(__dirname,'dist'), host:'localhost', compress:true, port:8888 } }
4.配置babel(很关键,可以让浏览器支持es6语法。)
cnpm install babel-loader babel-core babel-preset-env
在webpack.config.js中添加loader:
后续抽空补上打包jquery以及第三方插件的webpack的配置。。。。。。
