Angular设置别名alias的方法

设置别名

在根目录下tsconfig.json中添加baseUrl和paths

{
 "compilerOptions": {
 "baseUrl": "src",
 "paths": {
 "@app/*": ["app/*"],
 "@assets/*": ["assets/*"],
 "@env/*": ["environments/*"],
 "@views/*": ["app/views/*"],
 "@core/*": ["app/core/*"],
 "@constants": ["app/core/constants/*"],
 "@model/*": ["app/core/model/*"],
 "@interceptors/*": ["app/core/interceptors/*"],
 "@services/*": ["app/core/services/*"],
 "@validators/*": ["app/core/validators/*"],
 "@shared/*": ["app/shared/*"],
 "@components/*": ["app/shared/components/*"],
 "@directives/*": ["app/shared/directives/*"],
 "@guards/*": ["app/shared/guards/*"],
 "@pipes/*": ["app/shared/pipes/*"]
 },
}

访问环境变量

import { environment } from '@env/environment'

添加了@env别名，以便能够import { environment } from '@env/environment',从应用程序中的任何位置轻松访问环境变量。它适用于所有指定的环境，因为cli它会根据--env传递给ng build命令的标志自动解析正确的环境文件。
