SCSS Imports doesn't recompile css

[mvosz]

Hi and thank You for the template, so I could debug my code with the tailwind v4 update. The Problem starts, when I import another scss inside styles.scss and make changes inside of it.

styles.scss:
@use "./more";

more.scss:

html {
    background-color: #bada55;
}

change more.scss

html {
    background-color: deeppink;
}

Hi @mvosz 👋🏽 — are you able to point to a repo or Stackblitz showing this issue, so I can dig deeper? Thanks.

Hi, thanks for the repro.

Just so I can make sure I understand the issue you're seeing: making changes to the newly imported more.scss file are not being reflected by the dev server, and so don't show up in the browser window (even if you do a manual refresh), until you restart the dev server, right? Good find!

I've pinpointed this to the @import "./tailwind.css" line — if you comment this out then it works as expected. I've also confirmed that all works fine in a regular clean Angular v19 app (without Tailwind). I suspect this is something deep down in the Dart Sass or PostCSS library, and the interaction with the @tailwindcss/postcss plugin.

Interestingly, making changes to the tailwind.css file does trigger an update properly. I wonder if it's a timing/sequencing issue.

I'm not sure what to suggest at this stage; I'll keep digging to see if I can pinpoint the exact issue.

For now, you can trigger an update by saving your styles.scss file, which will trigger a rebuild and update the browser.

Side note: partials should be named with an underscore (so in this case _more.scss as that tells the Sass compiler not to generate a CSS file for it); though that doesn't impact this bug.

No problem. Ha! I know what you mean 😆 But I have faith that it will (eventually) be sorted out. This is the nature of open source, and we're lucky enough to have access to all these wonderful tools in the first place 😌
