Removing Internationalization | Nextbase v3 Starter Kits Documentation

Many saas products require internalization. But many don't need it too. Ultimately it is your customer requirements that matter.

If you don't need internationalization, you can remove it by following these steps:

Move all the children of the src/app/[locale] folder to the src/app/ folder.
Remove the [locale] from the src/app/ folder.
Remove the next-intl from the package.json file.
Update your middleware to this pattern. Pay close attention to the

// your imports stay the same

 * Public paths are paths that are accessible to everyone.
 * They don't require the user to be logged in.
 */

/**
 * Dashboard routes are paths that are accessible to logged in users.

const dashboardRoutes = [
  `/dashboard(/.*)?`,
  // ... other dashboard routes
];
