import { getNitroOrigin } from '#site-config/server/composables'

export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook('site-config:init', ({ event, siteConfig }) => {
    const origin = getNitroOrigin(event)
    if (origin.startsWith('https://fr.')) {
      siteConfig.push({
        _context: 'french nitro plugin', // helps you debug
        name: 'Mon Site',
        url: 'https://fr.example.com',
      })
    }
  })
})
```
