Issue
Note
This issue is Pages Router
next start
specific.Summary
When a CSS file was loaded statically from path
/
and dynamically from path/foo
, and the user navigates from/
to/foo
, the CSS file is not loaded in/foo
.Deep Dive
When a CSS file is server-rendered, it is cleaned up during the client render (e.g.
Link
navigation).next.js/packages/next/src/client/index.tsx
Lines 755 to 760 in 678b487
If the target route
/foo
dynamically imports the same CSS file, the client will skip loading it (as it was already loaded statically). But the client will still clean it up the server-rendered CSS file as above, which will result in missing the expected styles.Previous Work
Changes
Since we pass the list of required CSS files of the module to the client through the build manifest, included the dynamic-loaded CSS files to the corresponding paths of the build manifest.
How?
During the build, gather the dynamic CSS files from the dependency chunks, and append to the existing manifest entrypoint values.
