Next-i18next: Add support for useTranslation hook

[Jonesus]

Is your feature request related to a problem? Please describe.

React community is increasingly moving towards enabling functionality via the hook pattern which provides increased readability and reusability between components and projects.

Describe the solution you'd like

I wish this package would support using the useTranslation hook which exists in react-i18next since version 10, as the dependency of this project now would technically support it.

Describe alternatives you've considered

Currently my project uses the HOC approach, and the <Trans> component has also been considered, but I would much prefer using the hook.

Additional context

I haven't really dug into the insides of this project as of yet but if there's something I could do to help regarding the development I would be happy to do so if I manage to arrange my calendars :)

That's an awesome idea, I'm waiting new features implemented by react-i18next.
I tried to access react-i18next instance directly from next-i18next without success.

Do you plan to integrate new features directly from next-i18next or create a way to access react-i18next directly from next-i18next ?

Please read from https://github.com/isaachinman/next-i18next/issues/164#issuecomment-501430656 onwards.

If it makes enough people happy, I suppose we _could_ just import and then export various react-i18next methods.

I can also confirm that the useTranslation works when imported directly from react-i18next, sorry that I missed the discussion before submitting this issue... I think it could even be added as an example in the README.md!

As a personal opinion though, I would prefer to have a single dependency for my i18n needs (next-i18next) instead of having to import both this and react-i18next, especially when the latter is already a dependency of your package. I feel like I would rather use next-i18next as a Next.js optimized wrapper for the complete react-i18next rather than a reimplementation of just some of the features, but I can understand if you have a different vision for this package 👍

Thanks, I'll try to import react-i18next directly. However I have the same opinion as Jonesus.

[isaachinman]

I've added useTranslation to our exported class. Will go out with v0.42.0. Hope this helps!

[jonathangiamp]

Thanks, that will be very useful!
