vue-loader的配置

Posted 2020-12-08 em2464

build/vue-loader.coonfig.js

module.exports = (isDev) => {
  return {
    preserveWhitepace: true, //清除文本换行等情况空格
    extractCSS: isDev ? false : true, // 把vue的css提取到单独的文件，默认
    cssModules: { localIndetName: ‘[xxx]‘, camcelcase: true }, // 用法：<style module>
    hotReload: true, // 热更新，默认会自动判断是否开发环境自动开启关闭，其实关闭后也会刷新页面更新
  };
};

webpack.config.base.js修改如下：

const path = require(‘path‘);
const vueloaderOptions=require(‘./vue-loader.config‘)
const isDev = process.env.NODE_ENV === ‘development‘
const config = {
  target: ‘web‘,
  entry: path.join(__dirname, ‘../client/index.js‘), //__dirname 当前文件所在的目录地址
  output: {
    filename: ‘bundle.js‘,
    path: path.join(__dirname, ‘../dist‘),
  },
  module: {
    rules: [
      {
        test: /.vue$/,
        loader: ‘vue-loader‘,
        options:vueloaderOptions(isDev),
        exclude:/node_modules/
      },

rimraf——每次打包之前删除之前的包  执行命令 rimraf dist

package.json配置如下：

"scripts": {
    "test": "echo "Error: no test specified" && exit 1",
    "build:client": "cross-env NODE_ENV=production webpack --config build/webpack.config.client.js","clean": "rimraf dist",
    "build": "npm run clean && npm run build:client",
    "dev": "cross-env NODE_ENV=development webpack-dev-server --config build/webpack.config.client.js"
  },
