[Koc]

Steps to reproduce

1. Clone repository
2. Run npm run watch

Expected behavior

Actual behavior

www-data@php-fpm:~/html/apps/tables$ npm run watch

> tables@1.0.0 watch
> vite --mode development build --watch

Building tables for development
 
[vite-plugin-css-injected-by-js] Experimental dev mode activated! Please, for any error open a issue. 

(!) build.outDir must not be the same directory of root or a parent directory of root as this could cause Vite to overwriting source files with build outputs.

this can be fixed by specifying an "outDir" in the config. But doing this leads to a subdirectory in the js folder, instead of the build files just being at the toplevel, so the server can't properly find them.

yeah, I had attempt to fix that using outDir but no luck. That's why I've opened this issue (otherwise it will be PR with fix) 😄 .

But more or less same setup works fine in other apps, like forms. What's the difference?
