Is there an option for keyPrefix in i18next?

For my current project, I am utilizing both i18next and react-i18next. One useful feature of using the useTranslation hook from react-i18next is the "keyPrefix" option, which helps in reducing code duplication. However, there are instances where I need to access i18next functionalities outside of components. Is there any abstraction similar to useTranslation that would allow me to use parameters like ns or keyPrefix without having to repeat them every time I call the t function?

I have searched through i18next's documentation for such a solution, but I have yet to come across anything applicable.

In an attempt to address this issue myself using the adapter pattern, I encountered challenges with TypeScript support as I could not obtain the type of the key for the t function.

It's actually quite simple to achieve this using i18next. You can simply refer to the react-i18next documentation for guidance:

// Assuming JSON in namespace "translation" like so:
/*{
    "very": {
      "deeply": {
        "nested": {
          "key": "here"
        }
      }
    }
}*/
const { t } = useTranslation('translation', { keyPrefix: 'very.deeply.nested' });
const text = t('key'); // "here"

In addition, referencing i18next (as detailed in its documentation):

// For namespaces other than the default one
i18next.t('translation:very.deeply.nested.key');
// It is advisable to utilize the ns option:
i18next.t('very.deeply.nested.key', { ns: 'translation'});

If you wish to make it a default setting in specific JavaScript files, you can refer to: 

i18next.getFixedT(lng, ns, keyPrefix)
.

This response hopes to provide assistance.
