6.12.2 Works: https://stackblitz.com/edit/github-9r8kjuz1
6.13.1 Doesn't work: https://stackblitz.com/edit/github-9r8kjuz1-tuaijd5l

Describe the bug

I use tailwindcss-primeui, after upgrading to 6.13.1, the nuxt postcss warns ambigious name animate-duration-[450ms] and failed to process it.

Change the dep from 6.12.2 to 6.13.1 makes nuxt failed to process primevue tailwind utilities.

Thanks for opening an issue. I have a very similar project to this, and I noticed minor issues in the project setup..

1. In assets/tailwind.css, you are importing ./primevue/tailwind after tailwindcss/utilities, but I think I would recommend to import all Tailwind utilities first; moreover, I also tend to use layers within my PrimeVue CSS files, eg. @import 'primevue/common' layer(components).
2. I haven't made use of tailwindcss-primeui plugin, but it seems to support CJS for now, and you're using that in tailwind.config.ts -- not a big issue, but you could stick to using tailwind.config.cjs maybe.
3. Most importantly where the issue lies is in nuxt.config. So you have Tailwind CSS imported in assets/tailwind.css while the module tends to look for assets/css/tailwind.css (mind the /css dir). You added ~/assets/tailwind to nuxt.options.css yourself, and that is fine, but it doesn't integrate with the module, so you had two conflicting installations of Tailwind. To fix this, either move tailwind.css into a css/ dir within the assets directory, and no need to add it in nuxt.config; or, within nuxt.config configure the module like so: tailwindcss: { cssPath: false } (for the module to not install another CSS file) or tailwindcss: { cssPath: '~/assets/tailwind.css' } (and remove from css[], for the module to install this into nuxt.options.css itself).

Let me know how that goes. 😄

Sadly, it won't work.

Comparing to 6.12.2 this line is also missing:

ℹ Tailwind Viewer: http://localhost:3000/_tailwind/                                                   nuxt:tailwindcss 17:25:43

Sadly, it won't work.

I'll need to know what you did and what issue came up; the issue was fixed with the suggestions I provided on my end! Could you update the Stackblitz?

Comparing to 6.12.2 this line is also missing:

ℹ Tailwind Viewer: http://localhost:3000/_tailwind/                                                   nuxt:tailwindcss 17:25:43

This is intentional; you can access the viewer in devtools. The URL is only logged when devtools are disabled or in Nuxt 2.

[reitowo]

However in same configuration that line is outputed in 6.12.2, so I suspect, unless something changed between 6.12.2 and 6.13.1, tailwind may noy loaded properly.

I'll update that stackblitz later and post a new one here.

[reitowo]

Please take a look: https://stackblitz.com/edit/github-9r8kjuz1-n2rzo1ux

Same code but 6.12.2 still works: https://stackblitz.com/edit/github-9r8kjuz1-ny3t4uah

[reitowo]

Also notice that this error message is 6.13.1 only, when editing tailwind.config.ts and trigger a reload:

So, maybe something wrong with ts support between 6.12.2 - 6.13.1

[ineshbose]

Ah OK I found the issue..

It seems that your resolvedConfig loads two of the primeui plugins because of this:

https://github.com/nuxt/ui/blob/f2d387622ae6bc8781d7893b74595f4030f14a78/src/tailwind.ts#L82

I think I was aware of this code while working on 6.13, but didn't run into issues in my testing. I should provide a fix within this module in the next patch. Till then please stay on 6.12 🙏 sorry about this!

[reitowo]

No worries, thanks for debugging. Glad to find out what's wrong :)
