您可以创建一个文件，例如：components.ts并在这部分提到的所有组件，如：

You can create one file, for example: components.ts and in that component reference to all components, like:

export {Trigger} from '../trigger/ts/trigger.component'
export {Cmp} from '../cmp/ts/cmp.component'
...

比，当你想加载一个组件，你可以这样做：

Than, when you want to load one component, you can do:

import {Trigger} from '../components.ts'

这是分组是一件好事。

It is good practice for grouping things.
