I'll modify the language switcher to only translate specific routes while leaving others untranslated. Here's how we'll implement this:

Now I've implemented route-specific translation functionality:

1. Created a central configuration file utils/translation-config.ts that defines which routes should be translated and provides a helper function to check if a route is translatable.

2. Modified the language switcher to:

   • Check if the current route is translatable
   • Disable the language switcher on non-translatable routes
   • Show a visual indication that translation is disabled

3. Updated the direct translation component to:

   • Only apply translations on translatable routes
   • Clear translation cookies on non-translatable routes

4. Modified the layout script to:

   • Check route translatability before applying any translation
   • Ensure non-translatable routes always use English

With these changes, only the specified routes (/, /projects, and /how-it-works) will be translated based on the user's language preference, while all other routes will remain in English.

You can easily customize which routes should be translated by modifying the translatableRoutes array in the utils/translation-config.ts file.

I see the issue in your code. The logic in the isRouteTranslatable function is inverted, which is causing all routes to be considered translatable. Let me fix that for you:

The problem was in your implementation of the isRouteTranslatable function. You had:

This logic was inverted with double negatives:

1. pathname !== route - This checks if the pathname is NOT equal to the route
2. !pathname.startsWith($route/) - This checks if the pathname does NOT start with the route
3. These were combined with OR (||), which would almost always return true

The correct implementation should be:

This checks if:

1. The pathname exactly matches one of the translatable routes, OR
2. The pathname starts with one of the translatable routes followed by a slash

With this fix, only the routes you specified ("/admin", "/create-project", "/edit-projects") and their sub-routes will be translatable, and all other routes will remain in English.
