vux-cli3 项目文件分析 webpack-bundle-analyzer

安装

cnpm install webpack-bundle-analyzer -D

 

修改vue.config.js

module.exports = {
    chainWebpack: config => {
        if (process.env.use_analyzer) {     // 分析
            config
                .plugin('webpack-bundle-analyzer')
                .use(require('webpack-bundle-analyzer').BundleAnalyzerPlugin)
        }
    }
}

安装  windows下不支持xxx=xxx这种写法。为了支持这种写法，用npm安装cross-env

cnpm install --save-dev cross-env

 

修改package.json

"scripts": {
    "analyzer": "cross-env use_analyzer=true npm run serve"
  },

然后运行npm run analyzer
