依赖Webpack bundle analyzer对Angula
1、安装依赖 npm install webpack-bundle-analyzer@^3.0.3
2、对package.json文件进行配置
scripts下添加一条指令："bundle-report": "webpack-bundle-analyzer dist/stats.json"
3、对angular.json文件进行配置
"outputPath": "dist",
architect配置如下
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist",

}
]
},
"production": {
"optimization": true, // optimization buildOptimizer 两个参数改为false不压缩，打包后提交大一倍，但是构建时间减少一倍，上生产改成true，测试为false
"outputHashing": "all",
"sourceMap": false,
"extractCss": true,
"namedChunks": false,
"aot": true,

}
}
},
"extract-i18n": {

"src/tsconfig.spec.json"
],
"exclude": [
"**/node_modules/**"
]
}
}
}
4、执行ng build --prod --stats-json
5、最后执行npm run bundle-report 会单独打开一个页面展示如下，可以一目了然的看到各个模块大小和nginx压缩后的大小
