并行运行Angular和AngularJS框架

我找到了描述如何将Angular(2)组件集成到AngularJS中的资源,但所有这些都涉及像Angular项目一样设置AngularJS项目,需要来自TypeScript的转换器,需要ES6,需要import语句.我想在我的AngularJS应用程序中简单地使用Angular组件,而不会中断我现有的工作流程.这是可能的,如果是这样,我该如何实现它？我认为这是升级模块的目的,但我看到的所有教程都需要AngularJS应用程序中的import语句,这需要一个转换器.如果Angular应用程序需要提前编译,那没关系,但AngularJS应用程序无法转换,因为它在 django服务器上运行,我不想运行另一个带有转换器的服务器.

为了清楚起见,我当前的AngularJS应用程序由django提供服务.我想要包含一些Angular组件.这些在开发过程中不会被触及,因此可以提前编译它们而不影响工作流程.有没有办法将这些组件添加到AngularJS应用程序而不向AngularJS应用程序添加转换器？

将AngularJS应用程序逐步升级到Angular.

升级成功的关键之一是通过在同一个应用程序中并排运行两个框架,逐个移植AngularJS组件,逐步进行升级.这样就可以在不中断其他业务的情况下升级大型复杂应用程序,因为这项工作可以协同完成并在一段时间内完成. Angular中的升级模块旨在实现无缝增量升级.

I don’t want to run another server with a transpiler.

转换器可以在客户端运行.有可能但不推荐.

<script src="https://unpkg.com/zone.js@0.8.4?main=browser"></script>
<script src="https://unpkg.com/systemjs@0.19.39/dist/system.src.js"></script>
<script src="systemjs.config.js"></script>
<script>
  System.import('main.js').catch(function(err){ console.error(err); });
</script>

你可以用TypeScript中的Angular做任何事情,你也可以用JavaScript做.从一种语言转换到另一种语言主要是改变组织代码和访问Angular API的方式.
