Excluding the default language from the URL

[simon86pl]

Hello, I want to create a website with multiple language versions, with English as the default. Unfortunately, I have an issue. Even though the default version is set to 'en', you can still access it via '/en', but it should only be available under '/'. The other language versions should be accessible via '/de', etc. Currently, I have everything in /app/[locale]/page.tsx. Is there a way to configure this? The current solution makes no sense. I saw in the documentation that this was the default behavior on the Pages router. Unfortunately, it’s not the case in the App Router. I found a solution on YouTube, but it doesn’t fully work. I can access the English version without '/en', but I can still access the same pages with the '/en' prefix, which is unacceptable for SEO...

I've seen that similar topics have been raised, but the problem hasn't been resolved... I managed to create a working solution, but you need to have all files duplicated, for example, /app/page.tsx and /app/[locale]/page.tsx.
