webpack-bundle-analyzer用法

npm install -D webpack-bundle-analyzer

配置package.json：build里加上--report

"scripts": {

"serve": "vue-cli-service serve",
"build": "vue-cli-service build --report"

},

配置vue.config.js自动打开分析报告

var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

module.exports = {

configureWebpack: {
    plugins: [
        new BundleAnalyzerPlugin({
            openAnalyzer: false, // 在默认浏览器中是否自动打开报告，默认 true
        })
    ]
}

}
