Change language without modifying the URL (/[lang]/rest)

[VinceBT-BG]

What version of this package are you using?
2.6.0

What problem do you want to solve?
We have a dashboard app that is hidden from search engines, so we do not need SEO, using Next 13.5 with pages router and next-translate latest version and we would like to be able to change language without adding the locale inside the url, I see that setLanguage uses next-router to pass the locale but would it be possible to allow to change the locale without changing the URL ?

What do you think is the correct solution to this problem?
Maybe there is a way to use the NEXT_LOCALE cookie or something else to accomplish the same behavior, I am not familiar enough with this library

Are you willing to submit a pull request to implement this change?
It depends of the complexity of what would have to be modified

I'm facing a similar problem
I want a default route without being explicit on URL.. and another language to be explicit
Anyone has some idea?

We are on the same boat, trying to switch languages without using [lang]/route. the setLanguage complains about that the next/router is not found.

Error: No router instance found.
You should only use "next/router" on the client side of your app.

Source
components/organisms/Header/index.tsx (33:14) @ locale

  31 | date.setTime(date.getTime() + expireMs);
  32 | document.cookie = `NEXT_LOCALE=${locale};expires=${date.toUTCString()};path=/`;
> 33 | setLanguage(locale);

Ok, after finding this comment #1022 (comment)
we were able to implement a language switcher using ?lang=de or ?lang=en. without /en/ or /fr/ or /en/ in the path.

Attempting to implement the solution you refer to @Eusebiotrigo didn't work for me unfortunately. I still get:

Error: No router instance found.
You should only use "next/router" on the client side of your app.
