1.如果是生产模式，关闭angular的所有log。
在main.ts的入口文件中，
main.ts
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
if(enviroment.production){
enableProdMode();
window.console.log=function(){};
window.console.info=function(){};
window.console.warn=function(){};
window.console.error=function(){};
window.console.debug=function(){};
platformBrowserDynamic().bootstrapModule(AppModule)
.catch(err => console.error(err));
}
在环境中配置不同的enviroments
environment.prod.ts
export const environment = {
production: true
...一些其他的不同环境的配置
一些url的配置
};
默认配置
environment.ts
// This file can be replaced during build by using the `fileReplacements` array.
// `ng build --prod` replaces `environment.ts` with `environment.prod.ts`.
// The list of file replacements can be found in `angular.json`.
export const environment = {
production: false
};
/*
* For easier debugging in development mode, you can import the following file
* to ignore zone related error stack frames such as `zone.run`, `zoneDelegate.invokeTask`.
*
* This import should be commented out in production mode because it will have a negative impact
* on performance if an error is thrown.
*/
// import 'zone.js/dist/zone-error'; // Included with Angular CLI.
增加配置
environment.prod..dit.ts
export const environment = {
production: true
...一些其他的不同环境的配置
一些url的配置
};
4配置多环境在angular.json中配置

5文件打包
下面的是两种打包命令 npm run build
npm run builddit ，这个命令执行的是上面增加的dit配置文件
test也是经过 配置 --code-coverage
...
