Incorrect preview command in `nitro.json` when `output.publicDir` option is set

[alSergey]

Environment

• Node - v20.18.1
• Npm - 10.8.2
• Nitropack - 2.10.4

Reproduction

1. Open Stackblitz
2. Run npx nuxi generate
3. Open dist/nitro.json

Describe the bug

Due to the fact that the command npx serve ./public is generated instead of npx serve ./, npx nuxi preview does not work correctly and the server does not start.

Is it possible to change preview command to npx serve ./ when output.publicDir option is set?

So if I understand correctly to fix this issue we need to change the behaviour of npx nuxi preview and use ( in the command npx serve ) the output.publicDir if present .
Is it correct?

[alSergey]

If I understood everything correctly, then the npx nuxi preview command runs the command that is written inside the nitro.json file. The command is currently written there without taking into account the output.publicDir setting.

I’ll be working on this issue, but I noticed that Nuxt CLI sets cwd to the directory it’s executed from. So, npx serve ./public won’t work, but npx serve ../public does in the generate setup. In this case, should I prepend .. for static files? I’ll take on this issue and try to fix it.

Fixed in nitropack@2.12.x
