把部署、建站、AI 与网络问题，写成能直接解决问题的文章。

What medium-sized projects are really afraid of is that modules exist but do not have stable dependency directions and responsibility boundaries.

What is really difficult is whether the entire asynchronous link can remain clear for a long time.

What really determines whether the project can be modified later is whether the state boundaries, page responsibilities and component abstractions are set correctly from the beginning.
