next-sass: Custom Server routing doesn't automatically compile styles for css modules

[Kyle-Mendes]

Expected Behavior

When using a custom server, routing to a page should automatically bundle the styles of all included components.

Current Behavior

That is not the case. You will need to hard refresh the page to get the styles to be built.

Steps to Reproduce (for bugs)

1. Clone https://github.com/Kyle-Mendes/next-sass-modules/tree/custom-server (make sure you're on the custom-server branch
2. Run yarn dev
3. visit localhost:3000
4. Click "Test Page"
5. Observe: The Headline component is not styled.
6. Refresh the page
7. Observe: The Headline component is styled.

NOTE:

Sometimes, even doing a hard reload results in Headline not being styled.
