Question

我使用CLI在Angular 7上构建了一个角度解决方案。该应用程序有2个区域。它们没有以任何方式连接，但是它们使用相同的代码库。

现在我可以转到http://localhost:4200/app1或http://localhost:4200/app2。但是它们在同一实例上运行。我想修改我的配置，以便可以写类似

ng build --app=app1

并获得独立解决方案。有什么建议，我该怎么办？

下面是我的angular.json文件。如您所见，我已经准备好用于开发，登台和生产的设置。这意味着目前，我可以写

ng build --build-optimizer --configuration=staging

并获得用于登台环境的构建。

使用cli，您可以在同一代码库（repo）中生成多个角度项目，并且可以分别构建，开发或服务它们。这样，您可以在前端级别实施微服务架构。如果您在同一个域中拥有不同的产品，并且希望通过不同的路线将它们分开，这是最好的方法。

以下是一些步骤，可以帮助您构建这种架构

生成多个角度应用程序：ng generate application <project-name> click在此处获取信息
分别构建并提供它们：ng build project-name和ng serve project-name
配置路由：要使此路由成为可能，您必须配置nginx代理服务器。

您必须在nginx脚本中使用位置块才能从不同的项目提供服务，以下脚本仅用于演示，请参考docs以获得完整的实现。

server {
    listen 4200;

    location / {
        proxy_pass http://localhost:4201;  # your root project
    }

    location /app1 {
        proxy_pass http://localhost:4202;  # your app1 project
    }

    location /app2 {
        proxy_pass http://localhost:4203;  # your app2 project
    }

}

对于生产，您可以在位置块中提供相应项目的index.html文件
