Describe your issue
The project is a minimal angular project (--minimal) with only tailwind added.
The project has 2 changes:
- Added tailwind classes to index.html and app.component.ts
- Symlink:
ln -s ../../node_modules/@angular/core/README.md assets/README.md
New tailwind classes are not added in ng serve
without restarting it. Try to change bg-red-500
to bg-green-500
in app.component.ts
. The sqaure will disappear as bg-green-500
is not added to the css output.
This issue can be fixed by removing the symlink. Now class changes are added without restarting ng serve
(may even require rm -rf .angular
).
It does not matter what file type it is, the existence of a symlink is enough to break it.
Hey! This is a super weird one but it looks like a problem with Angular itself. We aren't producing any content or postcss messages that are different whether the symlink is there or not.
- On the initial build we are returning the expected content paths from our plugin for
postcss-loader
to hand off to webpack. - On subsequent builds Tailwind CSS itself isn't called at all by Angular (I'm guessing PostCSS itself isn't called)
- This problem is only present when a glob path is passed to postcss-loader AND there is a symlink inside the "root" (non-dynamic) directory of the glob path.
- I suspected this was a problem with the persistent cache but disabling the angular cache does not fix this.
All this to say I believe this is an issue with Angular and possibly webpack itself that underlies Angular. I would suggest you open an issue with Angular and see what they can uncover. I can help provide more info to the Angular and/or webpack teams as needed as well.
