angular - 在两个构建中拆分 Angular CLI 应用程序

问题描述

我有一个使用 CLI 在 Angular 7 上构建的角度解决方案。该应用程序有 2 个区域。它们没有以任何方式连接，但它们使用相同的代码库。

现在我可以去http://localhost:4200/app1，或http://localhost:4200/app2。但它们在同一个实例上运行。我想修改我的配置，所以我可以写类似

ng build --app=app1

并获得一个独立的解决方案。有什么建议，我能做什么？

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。这意味着此刻，我可以写

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

并为暂存环境构建。

解决方案

使用cli您可以在同一个代码库（repo）中生成多个 Angular 项目，并且可以分别构建、开发或服务它们。通过这种方式，您可以在前端级别实施微服务架构。如果您在同一个域下有不同的产品，并且您想通过不同的路线将它们分开，这是最好的方法。

以下是一些有助于您构建这种架构的步骤

  1. 生成多个角度应用程序：ng generate application <project-name> 单击此处获取信息

  2. 分别构建和服务它们：ng build project-name和ng serve project-name

  3. 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 location 块来为不同的项目提供服务，以下脚本仅用于演示，请参阅文档以获取完整实现。

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 location 块中提供相应项目的 index.html 文件
