How to transform json when generating?

[Ercilan]

I've tried writing a Vite plugin to transform JSON, which works correctly on the development server. However, when building and compiling, although the plugin is showing being called, the final result is outdated.
I use nuxt generate, here is a demo: https://stackblitz.com/edit/bobbiegoede-nuxt-i18n-starter-qmkpavhk?file=vite-plugin-i18n-transform.ts, although that i can't run it with nuxt generate
