Angular如何配置多套环境

1. 前言

在 Angular 应用程序中,默认情况下构建了两个环境文件 dev 和 prod。基于目标环境,您的应用程序可能具有不同的设置。您可以根据需要配置多个自定义环境。在这里,您将看到如何配置多个环境,如 staging、beta、QA、prod 等

2. 创建不同的环境文件

我们需要根据需要创建多个环境文件。这里我创建了两个文件:

  1. environment.stagging.ts
  2. environment.beta.ts

您可以使用 environment.prod.ts file 复制、粘贴和重命名(例如:environment.staging.ts),并根据需要设置环境变量值。

3. 修改 angular.json 文件
