error on initializing i18nprovider
this is my code snippet
function App() {
const { t, i18n } = useTranslation();
const i18nProvider: I18nProvider = {
translate: (key: string, options?: any) => t(key, options),
changeLocale: (lang: string) => i18n.changeLanguage(lang),
getLocale: () => i18n.language,
};
This is my error
Type '(key: string, options?: any) => string | TFunctionDetailedResult<string, any>' is not assignable to type 'Translate'.
Type 'string | TFunctionDetailedResult<string, any>' is not assignable to type 'string'.
Type 'TFunctionDetailedResult<string, any>' is not assignable to type 'string'.ts(2322)
ITranslationContext.d.ts(3, 5): The expected type comes from property 'translate' which is declared here on type 'I18nProvider'

Hi @jakshire01. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The error you're encountering is due to TypeScript's strict type checking. The
translate
function in your i18nProvider
is expected to return a string
, but the t
function from useTranslation
can return a string
or TFunctionDetailedResult<string, any>
.
To fix this, you need to ensure that the translate
function always returns a string
. You can do this by converting the result of the t
function to a string
. Here's how you can modify your code:
In this code, String(t(key, options))
ensures that the translate
function always returns a string
, which should resolve the TypeScript error.
For more information on how to use i18nProvider
, you can refer to the Refine documentation (https://refine.dev/docs/guides-concepts/i18n#creating-the-i18n-provider).
