Cannot find namespace 'i18next'

[JuhG]

🐛 Bug Report

Using version 9.0.10 typescript is complaining, that the function t is not typed. We're using the type WithNamespaces, but for some reason it didn't contain the types coming from i18next. Checking the type file, it looks like this:

Cannot find namespace 'i18next' - somehow importing the types is not working.

Changing
import i18next from 'i18next';
to
import * as i18next from 'i18next';
seem to resolve it.

Sorry if this has already come up, but I couldn't find it.

Your Environment

• runtime version: node 12.22.3
• i18next version: 20.4.0
• os: Mac

WithNamespaces is very old
please update react-i18next

https://react.i18next.com/latest/migrating-v9-to-v10

We definitely plan to upgrade, but it's an old and big project, so changing all the withNamespaces calls and Interpolate components will take time.
Does the change I proposed have any drawback?
Thanks for the help!

<= v9 is not supported anymore, so you have only advantages ;-)

@pedrodurek another reason why I would prefer to split the types...
those for react-i18next in this repo...
etc.

I was on vacation 😅. @adrai I didn't get your question, could you clarify a little bit more?

[adrai]

Welcome back @pedrodurek 😉. Do you remember, some time ago we discussed if there was a possibility to have the types defined each in the appropriate module, so i18next would not need to be updated im case a TypeScript change in the react-i18next interface is done.
I think it was here: i18next/i18next#1626 (comment)

As answered on the other issue, build-in types are always preferable. I've already faced some issues with external types and type augmentation, where the internal type definitions were being ignored in favour of the external library.

Hey @JuhG, let me know if the issue was fixed after updating the libraries
