研究方向

從 packages/angular_devkit/build_angular/src/tools/vite/angular-memory-plugin.ts 中第 163–178 行附近的 CSS 處理開始,追蹤 Vite middleware 鏈如何為樣式表完成。確認此變更在保留 CSS 提供功能的同時,允許自訂 middleware 處理 CSS 資源,然後驗證 serve 命令的行為。

Description

We are in the process of migrating from using webpack to esbuild/vite.

For development purposes, we need a way to dynamically switch from one theme to another. At this point, we have achieved it by proxying CSS or image files depending on the host name.

After switching to Vite, it turned out that it could work the same, apart from the fact that for CSS resources, our middleware is never executed.

I found a piece of code that seems to be the root cause. The AngularMemoryPlugin handles CSS files in a specific way and never executes next(), which terminates the middleware chain.

https://github.com/angular/angular-cli/blob/3d7b5f78bdab834cb50c441296c9bf31f7a5e764/packages/angular_devkit/build_angular/src/tools/vite/angular-memory-plugin.ts#L163-L178

Describe the solution you'd like

Ideally middleware chain should not be terminated in AngularMemoryPlugin for stylesheets (ie. next() should be called)

Describe alternatives you've considered

In the worst case scenario, we will find another solution for our use case. However, since the issue only pertains to CSS files, it would be really helpful if the middleware is executed for these files as well.
