webpack 编译less/scss文件
1、安装插件
处理less:
npm install less-loader --save-dev
处理sass:
npm install sass-loader --save-dev
2、项目目录:
layer.less为:
.layer{ width: 600px; height: 200px; background-color: green; > div{ width: 400px; height: 200px; background-color: red; } .flex{ display: flex; } }
layer.js为:
import './layer.less'; //import tpl from './layer.html'; function layer(){ return { name:'layer', tpl:tpl } } export default layer;
3、webpack.config.js配置文件(以编译less为例)
var htmlWebpackPlugin = require('html-webpack-plugin'); module.exports = { entry: './src/app.js', output: { path: __dirname + '/dist', filename: 'js/[name].js' }, module: { loaders: [{ test: /\.js$/, //以下目录不处理 exclude: /node_modules/, //只处理以下目录 include: /src/, loader: "babel-loader", //配置的目标运行环境(environment)自动启用需要的 babel 插件 query: { presets: ['latest'] } }, //css 处理这一块 { test: /\.css$/, use: [ 'style-loader', { loader: 'css-loader', options: { //支持@important引入css importLoaders: 1 } }, { loader: 'postcss-loader', options: { plugins: function() { return [ //一定要写在require("autoprefixer")前面,否则require("autoprefixer")无效 require('postcss-import')(), require("autoprefixer")({ "browsers": ["Android >= 4.1", "iOS >= 7.0", "ie >= 8"] }) ] } } } ] }, //less 处理这一块 { test: /\.less$/, use: ['style-loader', { loader: 'css-loader', options: { //支持@important引入css importLoaders: 1 } }, { loader: 'postcss-loader', options: { plugins: function() { return [ //一定要写在require("autoprefixer")前面,否则require("autoprefixer")无效 require('postcss-import')(), require("autoprefixer")({ "browsers": ["Android >= 4.1", "iOS >= 7.0", "ie >= 8"] }) ] } } }, 'less-loader' ] } ] }, plugins: [ new htmlWebpackPlugin({ template: 'index.html', filename: 'index.html' }) ] }
注意:postcss-loader在css-loader后,在less-loader前。
4、执行编译&查看效果
npm run webpack
