setting

ssr:false;

in nuxt.config.ts fixes the issue.
But I want the ssr

Hey! I have downloaded your reproduction but I don't see the issue. What am I missing? 🤔

Screen.Recording.2025-02-25.at.13.27.28.mov

One thing I noticed in your Stackblitz repro is that you were adding tailwind and not tailwindcss. tailwind is unfortunately not our npm name but since you got the client changes to work fine I suppose this is only a typo in the repro?

I've fixed the typo in Stackblitz.
The issue occured in Linux.
But I also could not reproduce the issue in Windows 11. I will try again with Linux Ubuntu and update you
Thanks a lot

I'm also getting the same issue.
Following the official tailwind guid to use tailwind with nuxt allowed me to work in dev environement.
But it doesn't work well when deployed. I need to set srr to false to make it work.
But setting ssr to false is not a solution for me

Yes The issue is occuring in linux system.
Tried both Chrome and Firefox.
VsCode and VsCodium
With official vue extension and without
The issue persists.

The repro you shared works for me even if I do pnpm build and pnpm preview without having to change the ssr flag to false.

I even set up a Linux VM just to test this and set up a new project based on the README. All I did in addition was to add that server/api/health.js file and it works fine including reloads in dev mode. Here's a video of me using that:

Can you please let me know the exact steps you did to see this error message? Otherwise I have to close this issue since we aren't able to reproduce this I'm afraid.

[Sourav9063]

Maybe this error is related.
This error shows when the ssr:false is set in nuxt.config.ts

@Sourav9063 I need help here with how to reproduce this error. Can you please line out every step you are doing to get this running? I tried changing the ssr flag on my Linux setup and it's still working as expected.

Were you able to reproduce this in the stackblitz setup you created? If so, what are the comments you run?

[Sourav9063]

@philipp-spiess
I downloaded the stackblitz setup
yarn install
yard dev
then the issue is shown in this video

Same.

When type npm run generate, the and run npx serve .output/public, it showns 404.

The steps i exactly followed the the nuxt framework-guides, and created a simple page.

Thank you.

npm run generate

will create a dist/ directory (not in .output/public) with everything inside ready to be deployed on a static hosting service.
